Creep Feed Grinding, Profile Grinding
The MACRO Creep Feed Series
Flexible and modular CNC grinding centers:
Excellent precision – economical – user-friendly
Our MICRON Creep Feed Grinding machines are highly flexible CNC grinding centers. With their compact design and excellent reliability, they have been especially designed for Creep Feed and Profile Grinding. Compared to conventional surface grinding, these processes allow high stock removal rates. As a result, MICRON Creep Feed Grinding machines offer a high level of dynamic rigidity to reduce undesirable vibrations.
MICRON Creep Feed Grinding machines feature precision linear guide ways, ball screws, and digital drives in all axes. The state of the art SIEMENS 840D CNC control allows precision contour dressing and grinding and offers up to 5-axis interpolation. However, alternative CNC controls (e. g. Fanuc) can also be installed.
The MICRON “MACRO” Creep Feed machine range is based on the innovative Moving-Wheel-Head (MWH) concept. All linear movements when positioning and grinding are performed by the grinding head. Compared to conventional moving column and moving table concepts, this design arranges the axes in a very compact way, which results in optimum force distribution and minimal thermal variation, properties which result in best possible process control over a long lifespan.
The most diverse range of areas of application
A high level of dimensional accuracy and surface quality – for almost all industry sectors
MICRON Creep Feed machines are used in almost every industrial sector where precision mechanical components are being produced. Wherever there is a need for accurate profiles or slots and / or close finish requirements, MICRON Creep Feed equipment offers excellent and highly economical results. In the aircraft engine and stationary turbine industries, components with poor machinability, such as turbine blades and vanes, can be ground very efficiently.
Further applications are the highly efficient production of automotive parts, saw tooth profiles, gear racks, gear rings, guides, work holding details, cutting tools, broaches and highly dense ceramic parts. Steering system components and rocker arms are machined in the automotive industry, stators and rotors in the hydraulic industry are other areas of application.
For most applications, conventional or vitrified CBN grinding wheels are used. In certain cases, however, the use of single layer plated super abrasives may be more economical.
What is Profile / Creep Feed Grinding?
- Grinding of any profiles on plane and round faces.
- Grinding wheels are dressed according to the piece profile.
- Multiple profiles over the wheel width allows shorter cycle times and higher throughput
- Is the best choice to machine grooves, serrations, deep slots and all kind of profiles.
- Achieves high stock removal rates for hardened material
- An economical way to machine super-alloys
- Has a robust and stiff design to grind the required form and surface quality in one grinding path.
- Depending on the surface quality maybe a second grinding step is necessary.
