Technical Specifications:
The KX-2 32/4.5 24 63A ES electrospindle is designed for high-performance applications. It operates at a maximum power of 32 kW at 4500 RPM under continuous duty (S1) with a maximum torque of 68 Nm and a current of 73 A. For intermittent duty (S6 40%), it maintains the same power at 3100 RPM, with a torque of 100 Nm and a current of 113 A. The spindle operates at a voltage of 400 V and has 4 poles, with a maximum rotational speed of 24,000 RPM. It supports both clockwise and counterclockwise rotation and is driven by an inverter.
Tool Interface and Bearings:
The tool interface is HSK 63A, and the spindle uses high-speed, high-precision ceramic angular contact ball bearings, arranged in pairs both at the front and rear.
Cooling and Lubrication:
Cooling is achieved through liquid means. The spindle features tool locking (S1) and an open clamp (S2) system. It includes a SYN/COS encoder with 1Vpp 256 pulses per revolution plus a reference mark. Tool release requires air pressure between 14.5-15.5 bar, while pressurization and taper cleaning require 0.5-1.0 bar and 6-6.5 bar respectively. Lubrication options include air tool, oil mist, MQL, and CTS lubrication.
Weight and Sensors:
The spindle weighs 100 kg and includes an encoder sensor. Optional features are available.
Performance Graph:
The performance graph illustrates power and torque across different RPMs for both S1 and S6 40% duty cycles, highlighting the spindle's capability to maintain high performance across a range of speeds.
