Jig grinding: Secure and reduce your manufacturing process for optimal surface quality with a single machine
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.
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.
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.
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.
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
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.
30,000 min-1, HSK-E40
42,000 min-1, HSK-E40
36,000 min-1, HSK-E50
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
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.
