Products Description
The CNC Cold Cutting Machine is a specialized equipment for high‑quality straight-line slitting of steel plates. Using a cold cutting process, it eliminates heat‑affected zones, prevents deformation, and avoids oxide scale. It delivers efficient and high‑precision straight-line cutting of steel plates, making it particularly suitable for applications where cut quality and environmental requirements are critical.
Industry Pain Points
- Oxide layer and slag generated by traditional thermal cutting
- Significant stress deformation – parts cannot be used directly and require secondary processing
- Processing pollution – harmful emissions and waste
Core Advantages

High machining accuracy and excellent surface finish

High efficiency – multiple blades slitting simultaneously for one‑pass forming

Low residual stress from sawing slitting process

Magnetic adhesion – quick and easy clamping, no complex fixturing

Mist cooling – no wastewater, no exhaust gas



Applications
- Straight-line slitting of steel plates (longitudinal/transverse)
- Dimension cutting of plates in shipbuilding
- Plate cutting for bridge steel structures, offshore platforms
- Steel plates for pressure vessels, chemical equipment
- Plates for rail vehicles, building steel structures
Selection Guide
- Cutting method: cold saw / band saw / multi-blade simultaneous slitting
- Plate thickness range: whether it covers your required thickness (especially for thick plates)
- Cut quality: oxidation-free, deformation-free, surface finish requirement
- Efficiency needs: whether multi-blade one-pass forming is needed
- Environmental configuration: mist cooling, chip collection
Maintenance
- Daily: remove chips, check saw blade/tool wear
- Regularly: lubricate guide rails and lead screws, check magnetic chuck surface
- Inspect coolant/mist system, prevent clogging
- Monthly: calibrate cutting accuracy, check band saw or circular saw tension
- Keep electrical cabinet dust-free; check cooling fan status
Frequently Asked Questions (FAQ)
1. What materials can the CNC cold cutting machine process?
It is designed for cutting steel plates, including carbon steel, stainless steel, and other ferrous metals. It is not suitable for non‑ferrous metals like aluminum or copper.
2. What is the maximum plate thickness the machine can cut?
Depending on the model, our machines can cut plates from thin gauge up to 100 mm in thickness. Please consult our specifications for model‑specific limits.
3. Does cold cutting generate any heat‑affected zone (HAZ)?
No. Because the process uses sawing or shearing without high temperature, there is no HAZ, no oxidation, and no structural change in the material.
4. How accurate is the cutting width?
Cutting width accuracy can be maintained within ±0.2 mm under normal operating conditions. Regular calibration and proper tool selection are required.
5. Can the machine perform both longitudinal and transverse cuts?
We offer dedicated longitudinal cold cutting machines and transverse cold cutting machines. For multi‑directional cutting, please specify your requirement so we can recommend the best configuration.
6. How often should the saw blade be replaced?
Blade life depends on plate material, thickness, and cutting volume. Typically, sharpening is needed after 200–500 square meters of cut area. Monitor cut surface quality as a guide.
7. What is the maintenance schedule for guide rails and bearings?
Lubricate guide rails and lead screws weekly. Check bearings and drive belts monthly. Replace worn parts every six months or according to usage hours.
8. Why does the cut surface show rough lines or steps?
Possible causes: dull or chipped blade, excessive feed rate, improper blade pitch, or loose blade tension. Stop the machine, inspect the blade, and adjust parameters.
9. Is magnetic clamping suitable for all plate sizes?
Magnetic adhesion works best on flat, ferrous plates above 5 mm thickness. For very thin plates (below 5 mm) or non‑ferrous materials, we offer mechanical clamping options.
10. Does the machine produce any harmful emissions?
The cold cutting process generates no fumes, oxides, or thermal gases. Mist cooling uses a small amount of environmentally safe coolant (or plain water) and produces no wastewater or exhaust.
11. What safety features are included?
The machine is equipped with protective covers, door interlock switches, emergency stop buttons, overload protection, and automatic chip evacuation to reduce operator contact with sharp waste.
12. How do I choose between a CNC cold cutting machine and a CNC beveling machine?
If your primary need is straight‑line slitting to width, choose the cold cutting machine. If you need edge beveling (e.g., V/U/X shapes for welding preparation), choose the beveling machine. Some projects use both in sequence.
