HPC 190 - Motor spindle for milling and grinding

The HPC 190 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 190 spindle platform accommodates housing diameters as small as 190mm, with speeds from 6,000 to 28,000 rpm, power from 8.5 to 114 kW S1 and torque from 43 to 150 Nm S1. The Spindle Exchange Program (SEP) guarantees no more than 24 hours of downtime (EU) to maximize machine availability and minimize capital investment in spindles. Built-in acceleration sensor maintains compliance and process safety while it speeds up part approval.

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.
