Mikron Mill S 600 U 5-axis machining centres now boast new high precision HVC140 (StepTec) spindles

Mikron Mill S 600 U 5-axis machining centres now boast new high precision HVC140 (StepTec) spindles
GF Machining Solutions’ Mikron Mill S 600 U 5-axis machining centres are now equipped with new high precision HVC140 (StepTec) spindles, which deliver increased process stability, quality and productivity, among other advantages, for precision mould and die makers.

The 13.5 kW, 42,000 rpm spindle units boasts Opticool technology offering enhanced polar thermal balance, controlling the temperature of the machine’s spindle and spindle bearings to improve part accuracies and surface finishes.


Opticool technology

In addition, an all-new bearing design that uses ultra-high precision ceramic hybrid bearings. As a result, radial and lateral stiffness are increased by 16% and 60% respectively. Low radial and axial run-out, as well as repeatability, at the tool interface of less than two microns is achieved.

Designed for mould and die makers looking to achieve high accuracies and to maintain unrivalled process reliability during lengthy and prolonged machining runs, they feature several construction features in support of that.

A rigid base construction combines high dynamic direct-drive technology with a range of design and build features, plus integrated on-board software that ensure thermal stability and, therefore, guaranteed high precision and process optimisation. These SMART software modules include:

Ambient Robust, which monitors and regulates thermal variation detected in the machine’s base and drives;

OSS (Intelligent Operator Support System), which helps customers optimise their machining processes based on workpiece specifications/dimensions and their specific machining priorities of speed, accuracy and surface finish;

ITC/ITC 5AX (intelligent Thermal Control), which eliminates the need for, or reduces the time required for, warm-up cycles.

This spindle system, working in conjunction with the machines’ Smart Technology software, helps reduce spindle warm-up cycle times and ensures high accuracy and process reliability.
