KEMMLER synchronous tapping chuck SK40-M3/M27 ER32 A95, form AD/AF

Application

For machining centres with synchronous spindle.

Execution

• Alloyed case-hardening steel with a core tensile strength of at least 950 N/mm²
• Case-hardened HRC 60 ± 2 (HV 700 ± 50), hardness depth 0.8 mm ± 0.2 mm
• Taper angle: tolerance quality less than AT 3 in accordance with DIN 7187 and DIN 2080.
• black-oxide and precision-ground.

Advantage

• Synchronous tapping chucks compensate for synchronisation faults
• Minimum length compensation in push and pull direction between synchronous spindle and screw tap reduces excessive thread flank friction forces.
• Reduces possible increase in axial forces during the cutting cycle to a minimum.
• Suitable for internal cooling.
• Max. coolant pressure of 100 bar.
