Tapping chucks for synchronisation SK30 - M3-M16 (ER20) - 85 DIN 69871

Application:
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 max. 100 bar.

• All holders are made of forged steel
• Specific, low warpage hardened
• Surface hardened HRC 58~60
• Hardening depth 0,8mm~0,9mm
• Taper angle tolerance < AT 3 according to DIN 2080
• Surface roughness Ra < 0,4 µm
• Tensile strength in the core of min. 800 N/mm² after DIN
• All functional surfaces fine machined
