KARL KLINK POT broaching machines

Since more than 40 years Karl Klink is a leading manufacturer of high-performance broaching machines and broaching tools for POT-broaching:

With this kind of process it is possible to achieve an efficient machining of external profiles in one broaching stroke by means of a tubular shaped broaching tool. High efficiency

The simultaneous cutting engagement of the tools all over the workpiece contour results in high cutting capacities and short production times. Automation and interlinking

Special adapted automatic loading and unloading systems for shortest cycle times in mass-production.

Workpiece range

Typical workpieces are with external teeth and in addition with circular guiding grooves.

Further very diverse external profiles (grooves, recess, curves etc.) can be POT-broached economically.

POT broaching tools

A complex, high-precision designed and manufactured tubular body is the seat of broaching tool segments and of workpiece guidances. High workpiece accuracy by

- profile cutting rings in the finish section

- high-accuracy guidance of workpiece through the POT body

Intensive cooling and lubrication

by internal channels of the POT for:

- long tool life

- high surface quality

- cleaning of broaching tools, workpieces and part adaptors

- lubrication of guiding bars for workpieces

Machine design

- two-cylinder POT-broaching machine with high-accuracy slide guiding

- single-cylinder POT-broaching unit

- special design of Table-up-type broaching machine for POT-broaching

Hydraulic drives

for high broaching forces and dynamic ranges
