How Much Can a 100T Press Brake Bend?
A 100T CNC press brake handles sheet metal bending jobs that fall in the most common range for job shops and sheet metal fabricators. With a 3-meter bed and 100-ton pressure, it bends carbon steel up to 4mm thick over the full 3-meter length, and up to 6mm thick over shorter sections. This makes it the standard machine for electrical cabinets, control boxes, HVAC ductwork, kitchen equipment, and general sheet metal enclosures.
The CNC backgauge positions the sheet with repeat accuracy of +/-0.05mm, and the operator programs bend angles and bend sequences on the controller. After setup, the machine repeats bends identically across production runs.
- Carbon steel up to 4mm at 3000mm bend length.
- Stainless steel up to 3mm at 3000mm.
- Aluminum up to 4mm at 3000mm.
- Copper and brass sheet for electrical busbars.
- Galvanized sheet for HVAC and ductwork.
- Press force: 100 tons
- Bending length: 3000mm
- Bed length: 3200mm
- Stroke: 100mm
- Distance between housings: 2500mm
- Backgauge axes: 2-axis (X, R)
- Controller: CNC with graphical programming
- Motor power: 7.5kW
- Weight: Approximately 6500kg
This machine size is the workhorse for:
- Electrical enclosure manufacturers bending cabinet panels and frames.
- HVAC fabricators bending ductwork and flanges.
- Kitchen equipment shops bending stainless sinks and countertops.
- Signage and display companies bending aluminum and stainless frames.
- General sheet metal job shops handling mixed production runs.
If your typical parts are under 3mm sheet and 3 meters long, the 100T machine is sufficient and costs less. If you regularly bend 5-8mm thick plate or need longer bending length, step up to 160T or 200T. For structural steel and heavy plate, a 300T or larger machine is required.
Q: What is the difference between a press brake and a folding machine?
A: A press brake punches the sheet between upper and lower dies to bend it. A folding machine clamps the sheet and swings a folding beam up to form the bend. Press brakes handle thicker material; folders produce cleaner edges on thin sheet.
Q: How do I choose the right die for my bend?
A: The die opening (V-width) should be 8-12 times the material thickness. For 3mm steel, use a 24mm V-die. Air bending with a 30-degree punch is the most common setup.
Q: Can it bend stainless steel?
A: Yes. Stainless requires about 50% more force than carbon steel of the same thickness due to its higher tensile strength. The 100T machine handles 3mm stainless at full length.
Q: What is the backgauge used for?
A: The backgauge stops the sheet at a programmed position to control the flange length. A 2-axis backgauge (X and R) allows multi-step bending without manual repositioning.
Q: How long does setup take between parts?
A: With CNC programming, setup between similar parts takes 5-15 minutes. New bend programs can be imported from CAM software or programmed at the controller.
