Tapping chucks for synchronisation BT 40 - M3-M12 - 81 | ER 16Application: For machining centres with synchronous spindle. Note: Synchro tapping chucks compensate synchronisation errors. Minimal length compensation on compression and expansion balances very small pitch differences between synchro spindle and tap, which can cause high frictional forces on the thread flanks. A possible increase of axial force during the tapping process is reduced to a minimum. Suitable for internal coolant. Coolant pressure up to
