Face drivers/Live centers
PIONEER Diaphragm Chuck is basically to clamp the workpiece ＂Soft＂ and ＂Evenly＂to avoid the distortion by utilizing the tensile strength of special material used for Diaphragm and jaw, and thus to achieve the hightest possible accuracy in turning field. It is also designed not to be affected by the centrifugal force at high speed, and can be used up to 10,000min-1 or over. It ensures super high precision and stable turning operation.
Diaphragm chucks
With the roller burnishing a high surface finishing can be obtained on a lot of metals.
Bored or turned surfaces with a superficial roughness of 3 RA can be finished at 0,4 - 0,05 RA in only one single pass. Roller burnishing replaces grinding, honing, lapping and other expensive secondary operations.
Roller burnish holders
Quick clamping/release of component without the problem of jamming.
Super precision-Radial Run-out Accuracy up to 0.002mm achievable.
High Torque Transmission.
Long Operation Life and high dirt resistivity.
Easy to operate.
Hydraulic mandrels
Rotary broaching is a machining process where material is removed to produce internal and external profiles with various geometries (hexagons, squares, special splines, involute), starting from a pre-hole and by using shaped tools.
Broaching holders
Grippex is powered by coolant. There is no need of any adjustment within the whole gripping range.
-Compact and light - Adjacent turret tool positions need not be empty.
- Powerful - stands high pressure up to 20 bar.
-Grippex doesn’t need high pressure for pulling properly. It can work from 0,5 bar onward.
-Clamps very close to the chuck, allowing short overhang of the bar.
-Clamps hexagon bars without need for spindle orientation.
-Can also be used as a pick-up unit with robot jaws.
