Microcut Honing System: Highest precision, easy to control
The Microcut Honing System developed specifically for smaller bores guarantees shape accuracy, surface quality and dimensional accuracy at the highest level even in series production.
Our technology has fundamental technical and economic advantages over established processes such as internal cylindrical grinding and long-stroke honing.
Especially for bores smaller than Ø 2 mm, where conventional processes such as honing and internal cylindrical grinding reach their limits due to the system, our process delivers previously unattained results.
With our unique innovative machining tools and the intelligent, force-sensitive control of the machining process, we offer an easily controllable and robust process with minimum dispersion.
The actual machining is carried out with tools coated with diamond or CBN grit (undefined cutting edge).
Our system is suitable for through holes.
sonic-honing technology: Highest precision AND productivity
The sonic-honing technology is based on the Microcut Honing System and is suitable for specific applications.
We combine the adaptive feed control* of the tool with a fast stroke of the workpiece in the sound range. This enables us to achieve a massive reduction in cycle time, a longer tool life and finer surfaces with the same grain size.
*Adaptive feed control: The feed of the tool is controlled depending on the torque applied.
The control and evaluation of the process is managed by a highly sensitive force control and can, for example, detect and trigger the following
Workpiece clamping technology: A key factor
For difficult, e.g. thin-walled and small components, workpiece clamping technology is an essential success factor for achieving high form quality and automation. Microcut can offer various corresponding systems.
