About BERGER technologie
BERGER technologie GmbH is a Swiss mechanical engineering company based in Gwatt near Thun. The company develops and produces multi-spindle drilling heads in five product lines (MSBZ-ER, MSBS, MSBZ-EM, MSBU, MSBV) for simultaneous drilling, reaming, countersinking and thread tapping on drilling, transfer and CNC machines. In addition, BERGERtechnologie manufactures and sells optical precision drill grinding machines (MEGA-POINT blue line, easy-point-grinder EPG1) as well as the wood tool grinding machine WTG1, including spare parts and service, and since 2016 also for OPTIMA and TATAR machines. In contract manufacturing, mechanical parts are CNC and conventionally turned, milled, laser-marked and assembled into assemblies, complemented by design in HiCAD as well as heat and surface treatment with partner companies. The workshop works with aluminium, steels, brass, cast iron and carbide. Customers come from mechanical engineering, metal and wood processing as well as medical technology; sales are handled worldwide via sales partners.

Materials and Processes
Aluminium
Milled and turned parts as well as housings and spindle carriers of the multi-spindle drilling heads made of high-strength aluminium alloys.
Case-hardening steel and tempered steel
Hardened, ground spindles as well as nitrided gears made of tempered steel.
HSS and HSCO
Cutting materials for regrinding drills on the MEGA-POINT and EPG1 machines.
Solid carbide (VHM)
Carbide drills are ground with diamond grinding wheels; MSBS drilling heads are designed for solid carbide tools.
Hard brass and spring steels
Drill points with corrected main cutting edge according to DIN 1412 B for hard brass and spring steels.
Grey cast iron
6-face grind according to DIN 1412 D for grey cast iron drilling applications; contract manufacturing of cast parts.
Cermet and diamond tools
MSBS spindle bearing for highly precise running of the latest tool materials.
