Drilling spindle, high speed

Precise HSSSC offers complete spindle systems for drilling and milling operations, manufactured by Precise GmbH, Germany. The company now offers a new type of synchronous motor spindle, SD 5084, to meet the requirement of small dimension and higher torque. This new spindle combines small dimensions and higher torque. A peak torque of up to 6 Nm (SI 4 Nm) is available over the whole speed range of 500-20,000 1/min. The nominal power of 8 kW at 20000 1/min is realized in a housing dia of 80 mm. This power density can only be reached by the usage of the synchronous motor. This spindle offers tool interface HSK E 32 for fully automatic tool change. Typical applications of this spindle are drilling of steel and titanium or milling of steel mould and dies. The possibility of tapping and option of coolant through shaft are the next development steps that are being targeted for this spindle. To operate this spindle, the new drive module PCB 11 has to be used. The drive module contains PWM frequency converter PCB11 with special software.
