1:1 Copy milling made easy. For toolmaking, mouldmaking, the jewellery industry, mints and engraving works, the use of the engraving machine means a slice of independence. There are practically no limits on individual creativity. For more than 50 years, the engraving machine has been constantly improved but we are still supplying spare parts for machines from the 40s. There can scarcely be any better proof of their robustness and reliability. The engraving machine’s functioning mode is simple but brilliant at the same time. And, above all, the surface quality of the tools produced easily outstrips the competition.

Outstanding features of the BEMA System 3500 engraving machine

  • an engraving machine which is easy to operate and handle
  • reduction range of 1:1.41 to 1:100
  • no relief adjustment because of exact positioning of the pivot on the stamp surface
  • enlargement
  • 1:1 or additional device without anti-clockwise adjustment
  • continuous feed
  • feed and speed change possible during the machining operation
  • automatic speed regulation of tool and model
  • almost immovable mass because of weight reduction during scanning process, using special aluminium from aeronautical engineering industry
  • controlled feeler arm through the use of double rollers
  • X/Y axis for precise adjustment of the reduction range
  • 2 adjusting microscopes for precise setting of milling cutter and callipers
  • Machine completely equipped with halogen machine light, high frequency inverter and motor milling spindle.

1. The specification

Your model can be made of plaster, steel, bronze or Duroplast. Of course, you can have a model made from wax and then develop a Duroplast model by means of an intermediate mould. The maximal model diameter is 250mm.

2. The tracer pin

The tracer pin scans the model. Since the machine operates without vibrating, even the slightest depressions are picked up.

3. The milling spindle

The milling spindle is firmly connected to the tracer pin and mills precisely what is scanned on the model. There is no need to supervise the complete scanning and milling process. The machine functions totally automatically, round the clock.

4. The stamping die

With geometric precision, the die can be engraved exactly or reversed. The material is tooling st
