The demand for high precision in machining process is increased more and more. To keep preciseness of the processed bore diameter, Tool Correction System is necessary. With this product, Tool Correction Control is carried out by the pressure balancing of the air pressure servo and the power boosting of the oil pressure. The elastically deformable Setting Head is radially deformed in micron level. Even after repetitive use, this Setting Head provides a stable linearity in proportion with no residual stress inside or metal fatigue.

The Head part is made with the highly-rigid diaphragm-pivot-type elastically deformable body to lessen the influence of the stick-slip. This product provides Tool Correction performance with high proportionality by the precisely-controlled hydraulic power.

Downsized elastically-deformable design to keep high rigidity for deep hole processing. Minimal-length Setting Head. High productivity in high processing and high precision are on the same vector.

This holder is a component of the Tool Correction System and composed of the uniquely designed Setting Head having air servo mechanism and rigid parallel elastic body for lath processing. The system with this holder offers:  Micron-level tip adjustment  High repeatability of less than 1 micron  Simple and rapid (less than 1 second) offset performance This product with the easy operation is appreciated by users of single-and multi-spindle automatic turning machine, single-function machine, copying lathe and special purpose machine for turning. The picture on the left shows a processing of a brake disc with this holder.

To meet the demand for processing of partly-tapered hole, this system provides highly accurate tip adjustment during processing. By combining a servo valve and a pressure sensor in the special hydraulic unit, direct hydraulic control is provided in semi-closed loop. The head is the Membrane Setting Head, which has less influence of the stick-slip. Highly precise increment/decrement of offset displacement available. Plus/ Minus taper processing from one direction is also possible. The Tool Correction Controller with the built-in sequencer has a user-friendly 5-inch display screen, on which parameters can be input with touch screen system.
