gantryLine SLM
High-precision grinding of long work pieces

The SLM model is a Technology Machine based on the gantryLine design. It is specifically conceived for the economic processing of long work pieces. The gantryLine SLM combines all required characteristics to achieve the highest quality and repeatability for reciprocation as well as creep-feed grinding.

This machine is conceived to process work pieces up to 6,000 mm in length. Equipped with three main spindles, it is capable of solving diverse grinding problems. Initially designed for processing of linear guides, this machine finds its place in a number of other industries as well. High levels of customization is achieved utilizing a wide variety of dressing units.

All axes are equipped with high-precision linear guides and absolute measuring systems. The main table movement via linear motor achieves velocities of up to 60 m/min even with heavy loads. Acceleration and deceleration curves are short increasing the economic benefits of this machine.

Vertical and cross-axes are driven via ball screws and servo motors.
