STANDARDS

Specializing

Precision Swiss Type and Brown & Sharp Type turned products according
    to customer drawings including all secondary work
Assembly work
Mechanical components for electrical analogue measuring instruments
Assembly units for mechanization and automation (for the assembly of the componets from the prvious item)

Materials

Stainless steels in special qualities for solenoid valves
Rost- und säurebeständige Stähle
Free- cutting steel alloys
CuZn- alloys
Al- alloys
CuZn- alloys
Other materials available upon request

Lathe processing

 Automatic turning centers and Swiss Type mechines (NC and cam control)
Range of diamenters < 1 to 42 mm
In addition to turning operations the following work can be done in one chucking operation:
Longittudial drilling (also excentric drilling)
Transverse drilling (also offset from center)
Milling (in all directions)
Innrt and outer reaming
Thread: cutting, forming chasing, whirling and milling

All the processing operations above can also ba done as a second side- secondary operation on the same machine

Finishing work

NC- finish turning
Milling
Drilling
Thread roling and cutting
Grinding: Throughfeed, recess, centerless between centers and clamped
Transfer machines with 4,6,10 or 12 stations on which different processes can be combined
Many units have fully automatic loarding and unloading equipment, also for very delicate and exceptionally small parts
Honing, standard and single-stroke

Assembly

Manual, semi and fully automatic assembly of components for:
Pneumatics
Hydraulics
Precision mechanics
Electrical analog measuring instruments

with the option of integreted dimensional and function testing
