Keyseating machines

Reliable and economical

With our many years' experience in mechanical engineering, we see ourselves as a competent partner for diverse industries - from drive technology, the armature industry, agricultural engineering and the pump industry to woodworking.

Leistritz keyseating machines ensure the economical manufacture of:

  • Feather keys/grooves
  • Tangent key grooves
  • Hexagonal profiles
  • Helical grooves
  • Blind hole grooves
  • Lubrication grooves
  • Spline profiles
  • Involute profiles 

In addition to substantially lower costs for machines and tools, keyseating provides numerous essential advantages as regards economy and flexibility when compared to broaching or slotting.


Polymat NC

Especially when being used for low batch counts, the drawing technology of the Leistritz Polymat model range displays its advantages with a great deal of flexibility as regards profile geometry.

The Leistritz Polymat NC machines are an economical solution for creating clearance grooves/gages in clearance boreholes (single or multiple groove). The Polymat NC is generally designed as a two-axle machine.


Polymat CNC

Especially when being used for low batch counts, the drawing technology of the Leistritz Polymat model range displays its advantages with a great deal of flexibility as regards profile geometry.

Whether it is being used for single-item production or in automated series operation, Leistritz Polymat CNC machines are universal and flexible. Thanks to the controlled axis, interpolation is possible. This way, special profiles in clearance boreholes (oblique, lubrication and twist grooves), grooves in blind holes as well as (ir)regular multiple grooves/profiles can be drawn in addition to the normal feather key grooves - and all this in accordance with DIN 6885.


Polyjet 50

The electric keyseating machine Leistritz Polyjet 50 opens a new dimension in profile and keyseating technology for the operator. Hydraulics are omitted thanks to the linear actuator. This way both the amount of space it takes up and the noise level are reduced considerably. This generation of machines has the same capacity as substantially more complex broaching machines as well as the flexibility and economy of a keyseating machine.

Applications: feather key grooves, inner and outer profiles, grooves in conical boreholes, twist grooves, varieties of profile also in mid and large scale.
