Machine Concept

Grinding operations setup

The SUU 320 machine is configurated for single grinding operations, external or internal grinding.

Hydrostatic grinding slides

Hydrostatic length- and cross slides, equipped with linear motors giving a feed rate of 1000 mm/s and a feed resolution of 0.01 μm.

Grinding spindles

A wide range of high-requency spindles are available. Grinding wheel peripheral surface speeds up to 80 m/s.

Work head

A unit consisting of work head spindle, driving plate, magnetic chuck or centric chuck and measuring unit. The work head is hydrostatic or roller bearing supported, equipped with a variable speed motor.

Gauging method

In process electronic gauging.

Chucking principle

Shoe centerless with magnetic chucking or centric chucking.


The units are fixed to the machine base and, as standard, equipped with rotating diamond disc, single point diamond, full profile diamond roller or hydrostatic radius dresser controlled by CNC path. Dressing is performed during work piece loading. The LIDKÖPING hydrostatic CNC radius dresser is generating the form by interpolation between the lenght and the cross slide. The torque motor in the dresser keeps the dressing tool perpendicular to the profile of the grinding wheel. This dressing concept gives a high flexibility with the possibility to dress radius, track form with end drop etc.

Control system

Graphical user interface provides user-friendly controls and integrated. Program Generator IPG. Control System, Siemens Sinumerik One.
