Precision machining – CNC milling, CNC turning & ball bearing cages since 1994

When comprehensive expertise is combined with many years of experience, precision is the logical result. Since 1994 bmk-Baumann GmbH & Co. KG has stood for high-precision CNC machining, CNC milling and CNC turning – reliable, flexible and quality-oriented.

We are your partner for metal and plastic processing at the highest level and manufacture precision parts for mechanical engineering, medical technology and the roller bearing industry.

CNC machining for the highest demands

Our modern CNC machines enable the precise machining of complex turned and milled parts – from individual parts and small series to special functional components.
Whether stainless steel, aluminum, brass, titanium or high-performance plastics such as Torlon, PEEK, PE, POM, PTFE or Plexiglas – we supply components with the maximum dimensional accuracy and perfect surface quality.

Specialist for ball bearing cages

A particular focus of our production is the manufacture of ball bearing cages for the rolling bearing industry.
Using state-of-the-art CNC machining technology and precise machining processes, we manufacture cages and components with the tightest tolerances – for durable and low-friction bearing solutions.
Our decades of experience make us a valued partner of leading manufacturers in the field of ball bearing technology.

Innovative production through adiabatic cutting

In addition to conventional cutting processes, we also offer adiabatic cutting – an innovative, material-friendly process that enables precise cutting edges without the influence of heat.
This technology allows particularly efficient and clean cutting of profiles, ideal for sensitive materials and high-precision applications.

  • Ball bearing cagesOur ball bearing cages are designed to meet the highest requirements in terms of tolerance, running smoothness, roundness, and surface finish. Among numerous other applications, they prove their worth in high-precision ball bearings for high-performance spindles, in medical engineering, as well as in the aerospace industry.
  • CNC turning & millingIn addition to conventional turning and milling, we do of course also have profound expertise in deploying state-of-the-art CNC technology for turning and milling.
  • Vibratory grindingOur centrifugal (disc) finishing machines, as well as our rotary and trough vibrators, deburr your workpieces in a cost-efficient manner.
  • Punching & formingWe get your parts into the best shape possible. On eccentric and hydraulic presses, we punch, form, and emboss your parts in accordance with drawings.
  • Adiabatic cuttingThechipless high-speed cutting of rods and tubes, also known as high-speed impact cutting (HSIC) or “adiabatic cutting”, has some serious advantages over chip-removing cutting processes.
