HPC 290 - Motor spindle for milling and grinding

The HPC 290 platform offers a broad range of metal-working solutions, not just outstanding spindles. The platform concept serves mold makers and part-production applications.
Ideal for roughing and finishing precision parts, the HPC 290 spindle platform accommodates housing diameters as small as 290mm, with speeds from 6,000 to 15,000 rpm, power from 35 to 66 kW S1 and torque from 279 to 512 Nm S1. The COOL-Core technology provide polar temperature stability for repeatable, reliable machining processes. The clamping capabilities of our spindle shaft interlock solution enable turning, milling and grinding with precise high throughput.

Monitoring options

The Spindle Diagnostic Module (SDM; black box), combined with Step-Tec's patented acceleration sensor, records all process-relevant data, including vibration along three axes. SDM also monitors and time stamps collision events > 30g.

Compensation

Any undetected spindle movement or temperature increase can cause inaccuracies and flawed surface quality on the finished workpiece. Step-Tec provides various monitoring options for machine compensation, including several resistance thermometers, placement for traditional thermal compensation and optional Axial Movement Sensor (AMS). The combination of these data-acquisition capabilities with Step-Tec's outstanding thermal stability offers the best possible machine compensation to achieve outstanding precision and surface finishes.

Spindle Diagnostic Software (SDS)

Analysis and data-logging software enables our technicians to conduct remove evaluations of the machining process to offer recommendations for improvements. This capability increases spindle service life, and records behavior from initial commissioning onward, providing field service engineers with a powerful tool for onsite diagnosis of machining problems.
