BEMA System 4001

3D engraving, reproduction and copy milling with the System 4001.

Tried and tested all over the world for decades.

Copy milling made easy. For toolmaking, mouldmaking, the jewellery
industry, mints and engraving works, the use of the engraving machine
means 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 4001 engraving machine

  • an engraving machine which is easy to operate and handle
  • large reduction range of 1:1.6 to 1:100
  • manufacture of convex and concave dies possible
  • profile flattening or heightening from 30% to 100>#/li###
  • no relief adjustment because of exact positioning of the pivot on the stamp surface
  • smooth 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 process, using special aluminium from aeronautical engineering industry
  • precisely-controlled feeler arm through the use of double rollers
  • X/Y axis digital scale for precise adjustment of the reduction range
  • 2 adjusting microscopes for precise setting of milling cutter and callipers

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 500mm.

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 coining punch

The punch can be smoothly reduced and engraved in the range between 1:1.6 and 1:100.
