The spindle carriage is reciprocated along the ways on recirculating roller bearings which provide smooth, friction free motion under any load. To obtain maximum positive control of the stroke, this assembly is reciprocated by a heavy-duty hydraulic motor.
Controlled expansion of the abrasives in the tool include a rapid initial-expand feature. The abrasives are expanded at an accelerated rate until they contact the bore surface; at that point, stone expansion is immediately slowed to a pre-determined feed.
Work-holding fixtures are adjustable up to 20" and wiring is encased in a power track (see above).
To facilitate work handling and provide the operator with an unobstructed view, the centerpiece of the spindle is 38" above the floor.
Clockwise or counterclockwise rotation and tool feed pressure are controlled from console. Horsepower load meter and cycle timer are optional.
Rayon-media coolant filter features automatic advance of filter material.
Solenoid-controlled directional valves meet ISO standards. Valves and 15 HP hydraulic pump motor are positioned for easy service.
The head lift is hydraulically adjustable.
Heat-treated alloy steel tooling with shock resistant tool steel holders are precision made.
