The number of grinding modules varies from 2 to 12, depending on customer requirements. All modules can be adjusted independently of each other via a computer-controlled grinding process. All actuators and drives operate pneumatically or electrically, which minimizes the risk of fire and makes a significant contribution to environmental protection.

The machines operate autonomously via an attached generator carriage. The machines are optionally equipped with a laser measuring system for measuring the rail cross-section, an extinguishing water system and the ability to grind points automatically. Handling, e.g. loading/unloading the machines, can be carried out using a built-in pallet truck, loading ramp or loading arm, depending on requirements.
