Jig grinding​: Secure and reduce your manufacturing process for optimal surface quality with a single machine​

Two-in-one solution

Two-in-one solution​

Combine Milling and jig grinding on a single machine to both reduce the part manufacturing process and increase surface quality. The closed grinding process (grinding + measuring) accelerates your time to market.

Process monitoring

Monitor your process

Dressing spindle is equipped with an acoustic emission (AE) sensor to track and visualize on the Heidenhain control the signal during tool dressing. The machine can be equipped with an additional AE sensor to track grinding operations in order to further optimize the process.

Mold and die dot matrix

Three- or five-axis grinding process

Thanks to the MIKRON MILL S/X U series extend your business opportunity by combining milling and grinding process on the same machine in three- or five-axis simultaneous. Get easily a surface quality of < Ra 0.06 µm.

Grinding process

Stable grinding process​

Easily and significantly increase surface quality on parts with the closed grinding process (grinding/dressing/measuring) and the monitoring through the AE sensors.

Mold and die packaging

Maximize your potential​

MIKRON MILL S/X (U) series machines are Automation ready and the grinding option does not impact standard workpiece dimensions or the standard pallet changer. Get automated parts changing to increase your production output while achieving 3 µm machining accuracy and less than 0.06 µm surface roughness.


Human Machine interface​

HMi

Boosted numerical control​

The MIKRON MILL S and X series can be equipped with either the Heidenhain TNC 7 or the Siemens Sinumerik ONE control system. Both HMIs are enhanced by an internally developed and patented Smart Machine modules, designed to boost productivity and elevate machining performance to the next level.​


High-quality Swiss made Spindle​

Precision engineered for extreme micromachining

STEP TEC high-speed Spindles use premium components and advanced thermal design for stable, precise, vibration-free micromachining at high speeds. Swiss-made in-house for unmatched quality, ideal for automotive, electronics, and medical applications.

OptiCool Spindle design

OptiCool​
STEP TEC’s OptiCool Spindle series ensures not only that the Spindle remains thermally stable, but that natural heat transfer to the Spindle support (e.g., Z axis) is limited to the lowest amount possible, in order to preserve the machine’s geometry.​

CoolCore Spindle design

CoolCore​ 
Where conventional stator cooling reaches its limits, STEP TEC’s CoolCore Spindle goes beyond the ordinary to lower the temperature and minimize temperature fluctuations in the rotating shaft.​
