Factory workshops for production of
workpieces for drills and cutting machines
The production of workpieces for drills and
cutting machines is separated in two factory
workshops. In one of the factory workshops are
located completely automatic machines ("R&F")
for rough grinding and fine grinding of details.
In the other factory workshop are installed
automatic grinders for rough and finishing
grinding ("Undercut", "NIB", "ROD Grinder", "Flexstep").
In this factory workshop are also located the
automatic grinders, used for production of the
initial or so called starting workpieces "RAW
material", as after that the material is
subjected to the subsequent operations until it
reaches the required form and dimensions.

for the production of high-quality technical
details. The machines are equipped with
peripheral units for precise temperature control
of the extrusion forms, drying of the materials,
automated dosing of colorants and management of
hot channel systems.
We produce items from 1 gr. to 500 gr. and the
ready parts may also be produced using moulds,
provided by the customer.
We offer ENGEL extrusion machines with closing
force of up to 250 tons; volume of injection
moulding – up to 500 gr., at maximum dimensions
of the instruments - 640 mm х 620 mm. We can
produce plastic items using your moulds or to
produce new moulds for you.
