ESTARTA-175 / ESTARTA-250Precision centerless grinding
Centerless grinding
These machines have been specially developed to achieve maximum versatility in conjunction with maximum productivity.
The optimized design of this grinding machine range gives maximum accessibility for different adjustments and machine set up, getting the maximum versatility. ESTARTA-175 and ESTARTA-250 centerless grinding machines feature linear motors for grinding and regulating, wheels dressers for high speed and precision dressing and natural granite bed for thermal stability. Designed to grind as an option with high-speed technology with CBN wheels.
Advantages
- A machine with an optimized design giving maximum accessibility for different adjustments and machine set up.
- The machine has been conceived with wheel headstock in cantilever for quick changeover times emphasizing key factors for this design like minimum distance to front bearing or wheel spindle shaft diameter.
- Roller guideway system of the machine with positional control using linear scales, providing two important advantages: extreme movement sensitivity and an environment-friendly machine, as the hydraulic equipment becomes superfluous, requiring lower energy consumption and reduced maintenance.
- New damping system in both guiding systems of grinding and regulating wheel slides.
- The combination of these guiding and damping systems yield in maximum precision even in the most severe working conditions.
