How Does a Small Press Brake Work?

The small Press brake sheet metal machine is capable of bending tonnage for small tonnages. It is composed of a frame, hydraulic system, foot pedal, small brake tooling. The mini press brake machine forms pre-bends by clamping the workpiece between a matching punch and die.

It has a wide range of press brake tooling selections with custom designs such as V dies, channel forming dies, and hemming dies.

The V dies are used to create a variety of angles of the bends and are the most common type of small press brake dies. The sheet metal press brake calculator is a useful tool to figure out the total bending force.

Small hydraulic press brakes offer solutions for bending smaller parts

The small brake press offers a solution for bending smaller parts.  It operates with two ball screws and a liner guideway to provide accurate results easily and reliably. The small hydraulic press brake machine has a wide range of CNC programs for precise processes.

Frequently Asked Questions: Small Press Brake Selection & Specs

 

1. What is a small press brake and main type ?

A small press brake is a compact sheet metal bending machine featuring a 40T to 100T capacity, designed for precision fabrication in electronics, automotive, and electrical cabinet workshops. The miniature sheet metal brake machine is a smaller version of a sheet metal bender with tonnage range of 20- 100 tons.

There are three types of small press brakes:

  • Small electric press brake
  • Small Hydraulic press brake: The oil cylinders drive a small hydraulic press brake and the synchronization is decided by the two torsion bars on both sides to move up and down.
  • Small CNC press brake machine: Electro-Hydraulic servo bending machine is synchronized by servo proportional valves and a grating ruler.

2. What thickness can this small press brake bend?

JSTMT small press brakes (40T to 100T) typically bend carbon steel plates up to 4mm to 6mm thickness, depending on the bending length and V-die opening width. For thinner materials (0.5mm to 2mm) or micro-components, lower-tonnage models offer higher speed and energy efficiency.

3. How do I choose the right tonnage and bending length?

Tonnage is determined by material type, plate thickness, and the chosen V-die opening. As a rule of thumb, bending 1mm mild steel per meter requires approximately 8 tons. Our engineering team provides custom tonnage calculations based on your part dimensions to ensure optimal machine sizing.

4. Can it bend stainless steel and aluminum?

Yes. Stainless steel requires roughly 50% more bending force than mild steel due to higher tensile strength, while aluminum requires wider V-dies to prevent cracking along the bend line. JSTMT machine parameters can be configured specifically for non-ferrous and high-strength alloys.

5. Can this machine produce my parts according to a drawing?

Absolutely. Simply send us your DXF/STEP files or engineering drawings. JSTMT engineers perform a free bendability and interference check to verify flange lengths, tool clearance, and angle repeatability before machine selection.

6. What tooling and controller are included?

Standard machines include segmented multi-V bottom dies and standard top punches with quick-clamp systems. You can choose controllers ranging from entry-level NC systems (Estun E21S) to multi-axis CNC systems (Delem DA41T / DA53T / Cybelec) based on your automation requirements.
