Every Punch Grinder We Build

Punch grinding is fine work on small diameters, and the machine has to hold the pin without marking it while the wheel takes microns off a shoulder. Our punch grinders clamp from 1 mm right up to 150 mm and swivel the workhead plus or minus 45 degrees so angled forms are ground rather than filed.

The Problem

What This Category Is For

Stamping dies stop earning the moment a punch goes undersize or picks up a burr, and sending punches out for regrind puts the press on hold. A punch grinder in the tool room turns that into a same day job, and lets you make replacement punches instead of buying them.

Who buys these machines: Stamping and progressive die shops, press tool makers, connector and terminal manufacturers, and maintenance teams keeping presses running on their own tooling.

Core Advantages

Four Things That Separate These Machines

Clamping from 1 mm Diameter

The WK22 clamps from 1 mm to 150 mm on both internal and external diameters, which covers pilot pins through to die buttons on the same machine.

Workhead Swivel Plus Minus 45 Degrees

Angled lands and tapers are ground by swivelling the head rather than by building a dedicated fixture for every form.

Workhead Speed 0 to 1000 rpm

Infinitely variable workhead speed lets small diameters run fast enough to cut cleanly and larger parts run slow enough to stay round.

25 mm Spindle Through Hole

Long punch blanks pass through the spindle instead of hanging out of the chuck, which is what keeps deflection out of the ground diameter.

Questions

Punch Grinder Questions

Can the machine grind internal diameters as well?

Yes. The WK22 internal spindle runs 10000 to 20000 rpm on ER11 collets, which is the speed range small bores need.

Is the machine CNC controlled?

Yes. Control brand is your choice from FANUC, SIEMENS, SYNTEC or GSK, and we normally recommend matching what your maintenance team already supports.

What size machine footprint should I plan for?

1200 x 500 x 1500 mm, at 1280 kg. It fits in a tool room rather than needing a dedicated bay.

Can I grind carbide punches on it?

Carbide requires a diamond wheel and a rigid setup. Tell us the punch material and geometry and we will confirm the wheel and the workholding before you commit.

What is the lead time on this machine?

15 to 45 working days after deposit for a standard configuration. Special control or fixture requirements are quoted with their own dated schedule.
