In the sheet metal industry, equipment configuration often determines product positioning. If bending machines are the "basic equipment" in sheet metal forming, then grooving machines are the "key process" that allows products to go from ordinary to high-end.
As industries such as architectural decoration, elevator panels, high-end furniture, and stainless steel products place increasingly higher demands on product appearance and bending precision, grooving machines have gradually transformed from optional equipment into standard equipment for high-end sheet metal processing companies.
1. What is grooving? Why is it so important?
Grooving (V-groove machining) is a process in which a U-shaped or V-shaped groove is cut into a specified bending line using a cutting tool before bending a sheet material.
Its core functions are threefold:
1) Reduce bending springback and improve angular accuracy
2) Achieve an extremely small inner radius angle in the bend, creating a sharper zigzag effect.
3) Ensure the bent surface is free of indentations and deformation, achieving a high-end visual effect.
In other words, grooving is not for making bending easier, but for making bending more advanced.
2. Which products must rely on the grooving process?
Grooving machines are used in almost all industries that have strict requirements for "lines, angles, and textures," for example:
Application areas
Typical products
Features
Architectural Decoration
Metal wall panels, curtain wall panels, hotel decorative panels
Requires a perfect straight-line visual appearance and a crease-free surface
Elevator manufacturing
Car panels, landing doors, decorative borders
The radius (R) must be extremely small; no indentations are allowed on the mirror surface.
High-end cabinets
Stainless steel cabinet body, countertop edging
The bend must be a sharp 90° angle, not a blunt one.
Advertising sign
Display boards and lightbox edging
Clean and crisp edges create a sophisticated visual effect.
Stainless steel furniture
Coffee table, display rack, custom space components
Pursuing a weld-free, scratch-free, and minimalist structure
If the product falls into any of the above categories, bending machines alone cannot achieve the desired results; grooving processing must be used in conjunction with bending.
3. What traditional processing problems does the grooving machine solve?
✅ Solving the problem of bending springback
Especially with 304 stainless steel and aluminum sheets, the springback is significant, making it difficult to form in one go using compensation methods. Grooving can improve the stability of the bending angle by 30%-50%.
✅ Avoid bending marks and surface damage
High-end mirror panels, titanium plates, and brushed steel plates are most susceptible to indentation when bent; after grooving, they can be formed with almost no protective film.
✅ Achieving small R angles or even "right-angle bends"
In ordinary bending, the radius (R) angle is at least equal to the thickness of the plate, while grooving can reduce the inner radius angle of the bend to about 0.2mm, resulting in a more refined visual effect.
✅ Reduce welding processes and improve appearance consistency
Many structures that originally required welding and grinding can now be formed in one step by grooving and bending, resulting in greater strength and a better appearance.
4. Why are high-end customers paying more and more attention to grooving?
✅ Stronger process expansion capabilities —— Can accept higher profit orders.
✅ Replacing some laser welding/splicing processes —— with more controllable costs.
In short: Grooving machines can directly affect whether a company can accept high-end orders and sell at higher prices.
5. What should you pay attention to when choosing a grooving machine?
1) Is the countertop structure thickened, and how stable is it?
2) Are the tool precision and adjustable angle range sufficient?
3) Does the control system support automatic compensation and margin control?
4) Does it support long/thick plate processing (e.g., 6 meters, 8 meters)?
5) Can the equipment meet the requirement of not scratching the mirror panel?
In practical use, a grooving machine with unstable precision not only cannot help, but may even slow down the production pace and increase rework costs.
6. ZYCO's grooving solutions

In addition, we provide our clients with free process evaluation and trial cutting services to help them confirm the grooving effect before making a purchase decision.
In the field of high-end sheet metal processing, the requirements for R-angles (bending fillets) often directly determine the final texture of the product, especially in industries such as elevator decoration, precision chassis, display cases, door panels, and building curtain walls. Many factories choose more advanced bending machines when improving bending accuracy, but still find that the R-angles of some products does not meet customer requirements - especially those parts that require "right angle effect, sharp edge presentation, and almost no rounded corners".
The problem often lies not in the bending machine, but in the processing method: For products with strict R-angles requirements, "Grooving + bending" is often far superior to traditional single Bending.
The following will explain why from the perspectives of processing principles and practical applications.
1. Why is it difficult to achieve an extremely small R-angles angle in a single bend?
Traditional bending methods (whether torsion, electro-hydraulic, or purely electric) are subject to the following technical limitations:
1) The material itself has resilience
Metal will automatically bounce back after being bent, returning to a larger angle, and forming a natural rounded corner at the bend. No matter how precise the bending machine is, it cannot completely eliminate this process.
2) The V-shaped opening of the lower die determines the bending R-angle
The larger the lower mold, the larger the R; however, even if a very small V-groove is used, the difference still exists:
Rounded corners are still visible
The outer side of the workpiece is easily damaged
Thick plates are prone to cracking
This makes it difficult to balance "precision", "appearance" and "strength" in a single bend.
3) The thinner the sheet, the more difficult it is to maintain a sharp angle when bending
Stainless steel sheets with a thickness of 0.8–1.2mm often require sharp edges, but when the material is too thin during bending, the R-angle is still obvious and it is easy to twist and deform.
2. How to make the R of the bend close to a right angle when grooving?
When the fold line is pre-treated using a grooving machine, the bending effect is significantly changed:
1) By thinning the bending area, the material is made to "fold along the line"
Grooving involves removing a portion of the material thickness along the bending line, making it easier for the sheet material to conform to the curved surface of the mold at the bending line, resulting in more concentrated creases and more even stress distribution.
The effect after bending is usually:
The R-angle almost disappears
Sharp and clean bending edges
Visually closer to a perfect 90° angle
2) Material rebound is significantly reduced
The material thickness remaining after grooving is very thin, and the springback behavior is almost eliminated, making it easier to achieve the accuracy requirement of ±0.3° after bending.
3) More friendly to sheet metal — no surface marks, no wrinkling
Grooving reduces bending force, making thin sheets less prone to:
leave indentations
Surface scratches
Wrinkles or deformation
This significantly improved the product's appearance.
3. In workpieces with strict R-angle requirements, three key scenarios where grooving is more effective than a single bend
1) Elevator industry: Requires "straight edges and sharp lines"
Mirror panels are most susceptible to bending marks. Grooving allows for the maintenance of elegant straight edges when bending, giving the panel a more premium feel.
2) Architectural decoration: Inside and outside corners must be "sharp and distinct"
Curtain wall aluminum panels, door frame moldings, etc., usually require that the edges be folded without rounded corners, otherwise it will affect the overall visual effect.
3) Precision equipment casing: pursuing a seamless visual appearance
Server racks, automated equipment enclosures, and the like require the sharpest possible edges to appear more compact and refined.
In these situations, a single bend is insufficient, and grooving becomes almost the standard procedure.
4. Grooving + bending ≠ increased costs, but rather enhanced competitiveness
Many factories consider grooving an extra step, but after actually trying it, they find that the benefits far outweigh the costs.
The defect rate dropped significantly
More consistent appearance
Customer complaints decreased
High-end orders are easier to meet the standards
Factory overall image improvement
Under the same equipment conditions, factories that can perform grooving have a significantly stronger order-taking capacity than factories that can only perform bending.
5. Summary
For products with stringent requirements for R-angle, there is always a technical limit to the ability to bend in one go. Grooving technology, on the other hand, raises this limit, making the bending effect go from "can be done" to "doing it beautifully".
If you want to improve the appearance of your products, increase bending accuracy, or enter a higher-end market, a grooving machine is a key piece of equipment that is well worth considering.

Understanding Custom Metal Stamping from an Engineering Perspective
Metal stamping is a process that transforms sheet metal into complex shapes using precision tooling and high-tonnage stamping presses. What differentiates high-quality stamping from general forming is:
1. Tooling Accuracy
High-precision dies (often 0.005–0.02mm tolerance control) determine part quality, cycle stability, and production cost.
2. Material-Forming Behavior
Engineers must evaluate:
Yield strength
Elongation
Springback behavior
Grain direction
Surface finish requirements
These parameters determine whether a part can be punched, drawn, or formed without cracking or deformation.
3. Progressive vs. Single-Process Stamping
Progressive dies integrate multiple forming operations into a single continuous process, ideal for high-volume automotive connectors, terminals, and brackets.
Single- or compound dies are suitable for large, thick, or structural components.

A superior automated truck loader relies on a robust mechanical structure as its "limbs," but its true soul lies in its "eyes" and "brain." This week, we'll delve into the core, revealing how the Gachn truck loader achieves highly intelligent, unmanned loading through the seamless collaboration of 3D vision, AI algorithms, and advanced control.
In the past two weeks, we discussed industry pain points and introduced the revolutionary "cargo box entry" mechanical solution. However, for the robotic arm to precisely extend into the truck bed and perfectly stack the loads, an intelligent system for perception, decision-making, and execution is indispensable. This is precisely what distinguishes Gachn from simply cobbled-together automated equipment on the market, making it a truly "intelligent truck loader."
I. Intelligent Eyes: All-Aspect Perception for Clear Vehicle Identification
Challenges: Vast Variations in Vehicle Parking: Improper parking, centerline deviation, and foreign objects in the cargo compartment (such as residual binding ropes or debris) can all lead to loading failures or even equipment collisions.
Our Solution:
Precise Modeling: The equipment uses high-precision LiDAR to perform an all-around scan of the parked vehicle, generating a 3D point cloud model with millimeter-level precision. This system automatically measures the length, width, and side panel height of the cargo compartment, as well as the vehicle's ground clearance.
Intelligent Judgment:Utilizing a self-developed intelligent detection algorithm, the system analyzes the point cloud data in real time. It automatically identifies whether the vehicle is parked within the permitted automated loading area and whether the centerline deviation is within a controllable range. Simultaneously, it acts as a "quality inspector," detecting any irregularities in the cargo compartment to prevent unstable stacking or equipment malfunctions caused by foreign objects.
Active Guidance: If the system detects that the rear panel is too high or the parking position is improper, it will proactively remind the driver via screen to "open the rear panel" or "adjust the parking position," achieving human-machine interaction and ensuring a perfect starting point for the operation.
(Video: Showing the 3D point cloud model of the vehicle generated after LiDAR scanning, with the measured length, width, and height dimensions marked)
II. Intelligent Brain: Strategic Planning for Optimal Loading Path
Core Technology: Proprietary Palletizing Algorithm and Schneider Electric High-End Control Platform
Challenge: How to convert known vehicle dimensions and the tonnage to be loaded into precise, neat, and stable palletizing coordinates and movement trajectories for each bag of cement?
Our Solution: Intelligent Calculation: After acquiring 3D scan data, our independently developed palletizing logic algorithm begins operation. Based on the tonnage of cement to be loaded and a mathematical model, it automatically calculates the optimal landing coordinates for each bag of cement and plans the most efficient, collision-free movement trajectory.
Flexible Strategy: The algorithm supports three modes: horizontal stacking, vertical stacking, and a combination of both. It can intelligently select or combine modes based on the truck bed dimensions, ensuring tight and neat stacking, maximizing truck bed space utilization, and facilitating unloading.
Precise Execution: The calculated trajectory instructions are received and executed by a control system centered on a high-performance Schneider 12-axis motion controller and a 15.6-inch large touchscreen. The stability and high processing power of the Schneider PLC ensure the synchronization, accuracy, and reliability of the actions of all servo motors, cylinders, and other actuators.
III. Neural Networks: Data Interconnection, Enabling Intelligent Factory Management
Core Technology: Loading Information Management System and Industrial-Grade Interface
Challenge: The automated loading machine should not be an information silo; it needs to seamlessly integrate with the factory's existing management system.
Our Solution: The driver only needs to swipe their card next to the loading machine, and the system automatically retrieves the pickup information (such as customer, product type, and tonnage) from the ERP system, eliminating the need for manual input and preventing errors.
After loading is completed, data (such as actual loading time and tonnage) is automatically transmitted back to the management system, forming a closed loop and providing real-time and accurate data support for financial settlement and production scheduling.
The equipment is equipped with an Ethernet interface as standard, reserving ample expansion space for the factory's future Industry 4.0 and smart manufacturing upgrades.
IV. Reliable Foundation: Distributed Layout and Top-Tier Components
We understand that even the most intelligent system requires stable hardware support. Unlike competitors who centralize subcontracting, steering, and packing mechanisms, resulting in "small maintenance space and difficult fault handling," Gachn adopts a distributed layout. This layout not only offers higher stability but also provides spacious maintenance access when maintenance is needed, allowing for rapid problem location and resolution, significantly reducing downtime and improving overall equipment efficiency (OEE).
Conclusion: True intelligence is the perfect integration of perception, decision-making, execution, and management. The Gachn loading machine is precisely such an intelligent loading expert with "eagle eyes," a "super brain," and "flexible limbs." It brings not only savings in manpower, but also a comprehensive leap in loading quality, management efficiency, and data transparency.

How They Work
Water Cooled Screw Chiller Operation
You will find that a water cooled screw chiller uses water as the main medium to remove heat from your process. The system pumps water through a sealed condenser, where it absorbs heat from the refrigerant. This heated water then travels to a cooling tower, where it releases the heat into the atmosphere. The cooled water returns to the chiller, and the cycle repeats.
Modern water cooled screw chillers often include advanced features that enhance performance and efficiency. For example, a double compressor system allows the chiller to handle larger loads with greater stability. You can benefit from a PLC control system, which provides smart monitoring and easy adjustments through a touchscreen interface. These controls let you track system diagnostics, log historical data, and even access the chiller remotely. Many models use eco-friendly refrigerants, which help reduce environmental impact while maintaining high efficiency.
Air-Cooled Chiller Operation
An air-cooled chiller works differently. Instead of using water, it relies on fans to blow air across exposed condenser tubes. The refrigerant inside these tubes releases heat, which the moving air carries away. This process makes air-cooled chillers easier to install, since you do not need a cooling tower or extra piping.
You can place an air-cooled chiller outdoors, such as on a rooftop or beside your facility. This setup saves indoor space and reduces installation complexity. However, air is less effective than water at absorbing heat, so air-cooled chillers may not match the efficiency or performance of water cooled screw chillers for large industrial loads.

You should also check for heat coming from outside, like sunlight through windows. Use these steps to guide your planning:
Calculate the cooling load for your building.
Check energy efficiency ratings, such as the Coefficient of Performance (COP), to see how much energy the chiller will use.
Think about capacity and if you might need more cooling in the future.
Make sure the chiller is easy to maintain and that parts are available.
Look at the total cost, not just the price to buy the chiller, but also the cost to run and maintain it.
Identify all heat sources, both inside and outside.
Choose the right type of chiller for your needs.
Know the flow rate and the temperatures you want for the water going in and out.
Tip: A good plan now helps you avoid problems later.
Site Selection and Plant Room Design
You must pick the right spot for your chiller. The plant room should be safe and easy to reach. Follow these steps for a good setup:
Select a location with good airflow and enough space for workers to move around. Avoid hot areas.
Build a strong, level foundation to hold the chiller’s weight.
Connect water and power supplies safely and securely.
Install high-quality pipes and check for leaks.
Test the system to make sure it works well and does not leak.
A well-designed plant room makes it easier to keep your chiller running smoothly.

Step-by-step Installation Guide for Water-cooled Screw Chiller
You want your building to stay cool. This guide shows you how to install a water-cooled screw chiller. Follow each step to make sure you do it right.
Foundation Preparation
Begin with a strong base. The chiller needs a flat and sturdy floor. You can use concrete or other tough materials. Put the chiller on a concrete floor that is level within 6mm. For bigger chillers, build a concrete base with a 50-100mm gap. Fill this gap with sand or pitch. The gap helps stop vibration and keeps the chiller steady. A good base stops movement and damage when the chiller runs.
Use concrete for a strong base.
Make sure the floor is flat before you start.
Fill the gap with sand or pitch for support.
Tip: A strong base helps your chiller last longer.
Positioning and Mounting
Now, put the chiller in the plant room. Leave enough space around it for workers and air to move. Place the chiller where people can reach it easily. Attach the chiller tightly to the base. Use bolts and brackets that the maker suggests. Check that the chiller is straight to avoid bending the frame.
Leave space for workers to get to the chiller.
Use strong bolts to hold the chiller.
Make sure the chiller is straight.
Utility Connections
Connect water and power to the chiller. Use good cables and pipes. Follow safety rules for electricity. Make sure the water supply fits the chiller’s needs. Check that all connections are tight and do not leak. Label each connection so you know what it is for later.
Use safe cables and pipes.
Connect water pipes to the right places.
Test for leaks after you connect everything.
Piping Installation
Put in pipes carefully. Pick pipes with the right size for your system. Connect pipes using normal ways for chilled water and cooling water. Add pipes that help stop vibration. Put a filter at the water inlet and clean it often. If your water is not good, use Y-type filters and check them a lot. Build and install pipes by following national rules.
Pick pipes that match your chiller’s power.
Connect pipes the right way.
Add filters and clean them to keep water clean.
Use vibration pipes to protect the evaporator.
Note: Clean filters and good pipes help your chiller work well.
Vibration Isolation
Vibration isolation keeps your chiller and building safe. Pick isolators like rubber mounts or springs based on the chiller’s size and weight. Put isolators between the chiller and its base. Follow the maker’s instructions for lining things up. Stop vibration problems by checking system frequencies. You can change these by adjusting mass or stiffness.

Tips for Successful Installation
Avoiding Common Mistakes
You want your chiller to last a long time. Making mistakes during installation can cause problems. Many people forget to check the base before putting in the chiller. If the base is not flat or strong, the chiller can shake or break. Some people do not read the manufacturer’s instructions. This can cause wrong connections or a bad setup. Always follow the steps from the maker.
Leave enough space around the chiller for workers. Tight spaces make fixing and checking hard. Workers need room to reach all parts. Another mistake is using pipes that do not fit the chiller’s size. Pipes that are too small or too big can leak or lower cooling power.
Tip: Check every step twice when installing. Ask for help if you are unsure about a part or connection.
Maintenance Planning
Regular care helps your chiller work well. You need a plan for daily, monthly, and yearly tasks. This helps you find problems early and avoid big repairs. Check the inlet and outlet temperatures every day. This shows if the chiller is cooling right. Look at water strainers each month to keep water clean and stop clogs. Test phase rotation and check the expansion valve every month. These steps help the chiller stay safe.
Some jobs need to be done once or twice a year. Use ultrasonic leak testing to find hidden leaks. Take oil samples and send them to a lab. Pressure wash the microchannel coil to clean off dirt. Update the software on control systems to keep the chiller smart.
