Vertical Turn-Grind Centers
Grinding with the INDEX V series
The machines are especially suited for the machining of chuck parts requiring internal and external grinding operations
- O. D. grinding spindle units: directly driven INDEX motor grinding spindles for maximum rigidity and precision trough largesized precision antifriction bearings
- I.D. grinding spindle units: High-performance servodriven antifriction bearing spindles
- Conventional as well as CBN tools can be used
- Dressing cycles, wheel contact detection and grinding wheel balancing are fully automated
- Automatic workpiece handling through pickup by the motor spindle as the active handling unit
- In-process measuring system
- Very good accessibility, resulting in easy setup that is unparalleled
The result speaks for itself:
- Grinding roundness: 0,1 to 0,5 µm
- Roughness Ra: 0,1 to 0,4 µm
- Roughness Rz: 1 to 3 µm
Grinding components from the modular building block system
The grinding technology is integrated into the existing basic version of the machine, without having to design a completely new machine, by using components from the existing INDEX modular system. Once again the high precision of the standard machine appreciated by many users turned out to be an advantage, since the system extension of the standard machine did not require any change to the basic structure. The result is a complete machining center showing all the features of modern
process integration. Hard turning and grinding on a single machine. With this machine, the user does not have to make any compromise. The existing full turning functionality of the work spindles, tool carriers and turrets is maintained and completed with the equally unlimited grinding functionality of the modular grinding components.
Optimal conditions for safe complete machining
The combination of the processes hard turning and grinding in one turn-grind center offers many advantages: The grinding allowance can be reduced by a hard rough turning operation. This reduces considerably the machining time for grinding - especially for internal
grinding. The INDEX complete machining centers are a unique opportunity for hard turning operations .Without special modifications to the standard machine, highest roundness tolerances and flatness tolerances can be achieved. The control software has a special programming interface for grinding. The automatic workpiece measurement offers all the advantages of inprocess measurement and of all post-process measurements.
