Machining

We provide heat treatment and machining of castings in the modern heavy mechanics operation at our parent company TOS VARNSDORF a.s.

Heat treatment

  • large car furnace with gas part heating at 7 000 mm x 3 000 mm x 1 500 mm, weight 30 t, all types of annealing possible up to the maximum temperature 580 °C
  • car furnaces (2 pcs) with electric part heating at 2 500 mm x 1 000 mm x 600 mm, weight 20 t, all types of annealing possible up to the maximum temperature 960 °C
  • shaft furnace with electric part heating at 1 700 mm and diameter 900 mm, 10 t, all types of annealing possible up to the maximum temperature 960 °C

Machining

We deliver both final treatment and roughing up to 25 t.

Castings are processed in modern CNC machines:

  • Horizontal boring and milling machines - TOS VARNSDORF
  • Portal milling centres - WALDRICH
  • Flat surface grinders - Schiess
