Grinding

Shafts

Shafts are needed in various applications in automotive and other industries. We are producing shafts for oil-mist separators, electro-motors, power tools, driving systems, for stator and rotor stacks…

Several technologies are combined: grinding, induction hardening, straightening, rolling, knurling and gear hobbing.

• Diameter from Ø8 up to Ø 40 mm, grinding up to Ø65 mm
• Length 400 mm
• Deep drilling up to 20D
• Fine grinding with tolerance up to 4µm
• Milling of complex shapes
• Hard turning

Shafts for oil mist separators

Oil mist separators are used in trucks and personal vehicles, and they contribute to a cleaner environment. Shafts are mostly produced in medium & high-serial volumes and in different materials, such as free cutting steel and stainless steel. The grinding of the shafts is important to achieve the requested tolerances and is important for us to have fully automated processes with 100% quality control.

Some of the shafts are overmoulded in our plastic division.

Shafts for electro-motors
