About Kaiser Maschinenbau
Kaiser Maschinenbau und Zerspanungstechnik GmbH & Co. KG is a family-run contract manufacturer in Toppenstedt (Lower Saxony), in operation for generations and focused on deep hole drilling technology since 1995. With a total of 28 deep hole drilling machines, 10 lathes, 5 milling machines and 3 honing machines, the company machines workpieces up to 20 m in length, 2000 mm outer diameter and 75 t in weight. Its service portfolio includes concentric and eccentric deep hole drilling (solid drilling, core drilling, boring, form drilling, peel rolling) using BTA, ejector and single-lip gun drilling methods, multi-spindle drilling, turning, milling, honing, lapping, sawing and straightening, complemented by a transportable deep hole drilling unit for on-site operations. Materials of all kinds are processed, including steel and titanium alloys, non-ferrous metals and plastics, among other things for turbine shafts, extrusion cylinders, high-pressure pipes, gearbox shafts, hydraulic blocks and medical implants. Customer industries include mechanical engineering, energy/hydropower, petrochemicals, oil and gas, and medical technology.

History
- 1916
Founded as a contract threshing business; essentially the company name Kaiser survives from this.
- 1960
Establishment of the turning shop as a second pillar, which developed and ultimately replaced the original business.
- 1995
Concentration of the company on deep hole drilling technology; metalworking and machining remain part of business operations.
