Description

Rotax Series machines are specifically designed for processing flat cylindrical parts, such as the mating flanges.

Advantages:

  • Great rigidity and stability.
  • Rich choice of standard and optional equipment.
  • Rotating table
  • Hydrostatic guide system.
  • Maximum grinding dimensions up to ø900 x 530 mm.
  • Spindle rotation speed 1450 rpm with a logical inverter option.
  • Spindle power up to 11 kW.

Specifications

Hydrostatics and hydrodynamics

All guiding elements are hydrostatic and their surfaces are perfectly polished. Hydrostatic guide lubrication works based on a closed loop system supplying lubricant under pressure (on the column, the table and the headstock), which ensures that ultra-thin oil film lies between the contacting surfaces of all guiding elements. The absence of direct contact with metal surfaces ensures reliability, excludes wear-out, and as a consequence the original geometric accuracy of the machine is maintained for the entire service life. Minimum friction when sliding – it means to use the full capacity of the machine, high accuracy, no stick-slip at the feed or striction effect, and ensuring smooth positioning, high precision, high surface treatment quality, and high load-bearing capacity.

Three automation levels: NC DIASTEP

NC DIASTEP is designed to facilitate the basic operations of grinding and controls.

Three automation levels: NC COMPACT PLUS

NC COMPACT PLUS with advanced profiling functions can store up to 50 different programs.

Three automation levels: CNC DIATRONIC

CNC DIATRONIC (based on Siemens 840Di) is a full-featured CNC that has a huge set of functions, an image editing program for complex profiles and a possibility of working with CAD systems.
