High speed of table moving
Hydraulic Surface Grinding Machine for Heads and Cylinder blocks
More constant speeds
2 Types of milling
Segmented Grinding Wheel
Surfacing of workhead with pre-chambre or bimetallic inserts
CBN AND PCD Tools
High precision grinding machining (without coolant) in a reduced processing times
Robust and stable Bed
Made in normalized and stabilized cast iron with large ground guides
The head slides on rollers Guides (available on ALPHA 17-18-23)
In this way the thousandth movements are very precise and highly accurate without jamming .
The spindle , hardened steel , is housed on roller bearings.
The spindle motor rotates at variable speed controlled by inverter
The automatic reciprocating movement of the table is hydraulically controlled or ball screw
Robbi PLC Program
Robbi PLC Program work in the ball screw version and it is very useful during CBN and PCD grinding
at the end of the process the spindle stop rotation and it is oriented: in this way the tools are not on direct contact with the machined surface.
table returns to the start position without the need to raise the head
Spindle Separated from Wheel Motors
Best spindle cooling reduction of the thermal elongation of the spindle
