How are press brake punches made?

They are machined from tool steel, heat treated, then precision ground to final dimensions. The grinding after heat treatment sets the tool height and the profile accuracy.

Why is press brake tooling ground after heat treatment?

Heat treatment distorts the material, so the final dimensions can only be held by grinding afterwards. This is what gives the tool an accurate and repeatable height.

What should be on a tooling inspection record?

The interface and tang dimensions, the overall height, the profile angles and radii, and the hardness of the working surfaces, plus the material grade so the rated load can be checked.

Does the manufacturing location affect tooling quality?

Not by itself. What affects quality is the specification, the manufacturing tolerance and the inspection applied. Ask any supplier for those in writing.

How Press Brake Tooling Is Made: Machining, Hardening, Grinding

How is press brake tooling manufactured?

Press brake punches and dies are machined from tool steel, heat treated, then precision ground to their final dimensions. The grinding step after heat treatment is what sets the tool height tolerance and the profile accuracy.

The manufacturing sequence

Each step is a control point. Heat treatment moves the material, so the final dimensions can only be set after it, and the grinding that follows is where the tolerance is actually achieved.

Design. The profile is drawn against the machine interface, the clamp and the load the tool will carry.
Machining. The blank is cut and profiled from the specified tool steel.
Heat treatment. Induction hardening at the working surfaces, or through hardening for dies.
Grinding. The working faces, the tang and the seating faces are ground to final dimensions.
Inspection. Interface dimensions, tool height and hardness are checked against the drawing.

Why is grinding done after heat treatment?

Because heat treatment distorts the material, sometimes by more than the tolerance the tool is allowed. Grinding after hardening removes that movement and is the only way to hold an accurate tool height.

What each manufacturing step controls
Step	What it controls
Design	Whether the tool fits the machine and carries the load
Machining	The blank geometry and material usage
Heat treatment	Hardness, wear life and toughness
Grinding	Tool height, tang fit and profile accuracy
Inspection	Whether the tool matches its drawing

What does the workshop sit inside?

The factory is in Bowang District, Maanshan, Anhui Province, a tooling and blade manufacturing cluster. Bowang is known as China's blade and tooling district and is a national-level cluster for machine tool and blade dies.

The cluster is a location fact, not a claim about any individual order. Buyers should assess any supplier on its own specification, inspection and delivery record.

What should a tooling inspection record contain?

The dimensions that decide whether the tool fits and bends correctly: the interface and tang dimensions, the overall height, the profile angles and radii, and the hardness.

Interface and tang dimensions against the drawing.
Overall tool height, which drives the tooling setup.
Profile angles and radii, which drive the bend result.
Hardness of the working surfaces.
Material grade, so the rated load can be verified.

How is tooling packed and shipped?

Tooling is packed so the ground and hardened faces cannot contact each other or rest on the tip in transit, because damage in transit is the most common cause of a tool arriving out of specification.

Segments are packed in their sets so that a matched group of segments arrives and stays together, which matters for the bend angle along the length.
