Mechanical processing

Mechanical processing is carried out in our company using conventional as well as modern NC and CNC-controlled machine tools.  Turning, milling, planning or sinkhole drilling – we offer the perfect solution for every need.

 B = borehole, depth = 1000 mm
The size of the workpiece depends on the tool and machining type.

Fettling shop and Heat Treatment

In our modern fettling shop, the components obtain the required finishing through flame cutting, jointing, welding and reciprocating grinding. The essential mechanical and technical values can be adjusted using a correct heat treatment method.

 Heat treament methods

  • Annealing 
  • Quenching and Tempering in various mediums (tempering after quenching):

    • Air (different movements)
    • Hardening oil (modified high- Performance quenching oil)
    • Polymer solution (different concentrations possible)
    • Water

  • Austenitising
  • Soft annealing 
  • Stress relieving
