Product Description

Product Description

Our press brake dies adopt 42CrMo alloy steel with forging, overall quenching and cryogenic tempering, hardness HRC47±2 for high wear resistance and toughness. We provide standard and custom dies including acute punches, gooseneck dies, multi-V bottom dies, flattening and radius forming dies, fitting most CNC and conventional press brakes. CNC precision grinding controls tolerance within ±0.03mm for accurate bending on carbon steel, stainless steel and aluminum. Standard dies in stock, custom orders available per your drawings.

How to choose correct press brake tools for your needs

The customer who knows what he wants, will be glad to give them some of our knowledge, info, and experience.
We will try not to base on any tooling system but just the possible geometry of tools and their possibilities for bending.and divide it into the simple following categories:
 
A-Bending punch - an upper tool so the tool will be attached directly to the moveable beam of the press brake or upper holder on the beam and will be moved together with the beam. 
 
B-Bending die - a lower tool to be attached to the press brake table or lower support and stay fixed.
 
C-Tooling sets - complete sets of tools including upper and lower parts (mainly part and die) but used for special applications so a lot of times cannot be used without each other (like Z-bending tools) or used with a lot of limitations (like hemming punch). So these tools are usually sold, manufactured, supplied, and used only as a complete set together.

FAQ

1.What are the different types of CNC press brake dies?
Common types of CNC press brake dies include:
V-dies: Most common type, with a V-shaped opening that allows for various bending angles.
U-dies: Used for bending metal into more rounded or curved shapes.
Multi-V dies: Dies with multiple V-shaped notches, allowing for different bending angles in one die.
Straight or flat dies: Used for forming straight edges or flanges.
Custom dies: Specially designed dies for specific projects or parts, often used for complex shapes.
 
2. What materials are CNC press brake dies made of?
CNC press brake dies are typically made from high-quality, durable materials, including:
Tool steel (e.g., AISI D2, AISI O1, or other high-carbon steels) for wear resistance and long life.
Alloy steels for higher toughness.
Carbide (for specialized applications requiring extreme hardness and durability).
Hardened steel for maintaining die integrity under heavy use.
The material choice depends on the type of bending, required precision, and expected lifespan of the die.
 
3. How do I choose the right CNC press brake die?
Selecting the right die depends on several factors:
Material type: Different materials (e.g., aluminum, steel, stainless steel) may require different dies or die shapes.
Bending angle: The desired bend angle and radius will dictate the type of die (e.g., V-die for acute angles, U-die for rounded bends).
Material thickness: Thicker materials require dies with a larger opening to accommodate the sheet metal.
Part geometry: Custom dies may be needed for complex or unique part shapes.
Tolerance requirements: Precision parts may require specialized dies to ensure consistent bending results.

 4. What is the importance of the die opening in CNC press brake dies?
The die opening or "V-gap" is crucial because it determines the bending radius and the angle of the bend. A smaller V-gap will create a sharper bend, while a larger V-gap allows for a gentler bend. The proper die opening is essential to achieving the desired part geometry, especially for materials with varying thicknesses and hardness.
 
5. How are CNC press brake dies maintained?
Proper maintenance of CNC press brake dies is essential for ensuring consistent performance and longevity. Key maintenance steps include:
Regular cleaning: Remove metal debris, rust, and oil buildup from the die.
Inspect for wear: Check for damage such as cracks, chips, or excessive wear.
Lubrication: Apply lubricant to the die surfaces to reduce friction and wear.
Regrinding or reconditioning: Over time, dies may require regrinding to restore their original shape and sharpness.
Storage: Store dies in a clean, dry environment to prevent corrosion or damage.
 
6. How can I increase the lifespan of CNC press brake dies?
To extend the lifespan of CNC press brake dies:
Use the correct die for the job: Ensure that the die is suitable for the material and thickness you're working with.
Avoid overloading: Ensure the press brake machine is not operating beyond its capacity, as this can cause premature wear or damage to the die.
Use proper lubrication: Regularly lubricate the die and sheet metal to reduce friction.
Prevent metal build-up: Clean the die regularly to prevent material buildup, which can damage the die surface.
 
7. Can CNC press brake dies be customized?
Yes, CNC press brake dies can be customized to meet specific requirements for complex parts or unique geometries. Custom dies are often designed for specialized bending tasks and can be tailored to the thickness, material type, and desired angle of the parts being produced.
 
8. How do CNC press brake dies affect part quality?
The quality of the die directly impacts the accuracy, consistency, and overall quality of the bent part. Properly designed and maintained dies ensure:
Consistent bend angles across multiple parts.
Precise control of the bend radius for tight tolerances.
Minimal defects such as wrinkles, cracks, or deformation.
Longer tool life, reducing downtime and maintenance costs.
