Micron diameter correction head specialized for finishing on small machining centers (BT30 shank class).
The "GR-1 Ver.2" is an ATC mechanical correction head specifically designed for micron adjustments in lightweight machining centers. It can be used manually or automatically and is a lightweight, compact correction head. For error correction after tool changes, micron adjustments can be easily made without using a digital gauge inside the machine, allowing for immediate processing without the need for re-tightening. Additionally, automatic feedback correction for mass production boring processes can be performed using an NC program when combined with measurement and drive units. Please feel free to contact us if you have any inquiries. 【Features】 ■ 1 rotation of the ring equals 1μm ±0.5μm ■ Immediate processing after correction (no locking work required after correction) ■ Manual adjustment is a simple operation of turning the ring to align with the mark ■ No modification of the machine is necessary. It can be used immediately on existing machines, not just new equipment ■ Standard compatibility with axial coolant. Max. 2MPa *For more details, please download the PDF or feel free to contact us.
