After all, who doesn't like to have a partner who has made "pure perfection" his business and achieves it every day?

Grinding of special tooth profiles Even today it is often advantageous to manufacture spur toothed profiles using semiautomatic grinding processes. That, however, demands high expectations from the grinding specialists. The interaction of machine, metrology and grinding specialists generates tooth profiles with micron precision.

NC grinding of the profiles is carried out on a KAPP VUS 55 P and a VUS 57 P machine. These machines have been improved specifically to meet FRENCO's requirements for high precision. Both dressable grinding wheels and CBN grinding wheels are used to grind internal and external tooth profiles. Specially developed software modules allow the machining of worm gears. Topological grinding of unusual modifications is also possible. Grinding of internal profiles of the highest quality requires workpiece-specific mounting fixtures and grinding arms, which makes a consultation with FRENCO's specialists...

The wire erosion machines are tuned to high precision through sophisticated technology. They are positioned in a fully clima-tised room. In combination with the know-how of the operating staff, this results in a fantastic composition, which leads to a brilliant blend of unimagined accuracy. The extraction hoods provide a constant air humidity The air temperature is monitored in several places within the room, particularly in the vicinity of the EDM machine. The temperature of the machine is kept at a constant level via an internal water cooling system.

Pre-Machining FRENCO has specialised in the manufacture of gears and splines. The pre-fabrication process is carried out by our partner company Munkert GmbH. Munkert is specialised in individual high-precision components and small batches and stands out due to their state-of-the-art production engineering and an experienced and highly qualified team. The equipment includes NC lathes, 4-axis CNC milling machines, a 5-axis CNC machining centre with high-speed spindle and the necessary Mastercam X2 system as well as highly precise grinding machines for internal, external cylindrical and surface...

Inspection After the manufacturing process, each gearing profile is thoroughly inspected. An inspection certificate guarantees the faultless condition and gives detailed measurement results. There are three Klingelnberg gear measuring centres, one Zeiss CNC co-ordinate measuring machine Prismo Navigator 7 HTG with rotary table, one SIP length measurement machine and a combined roughness and contour measurement device by Mahr. You can rely on our inspection! After all, FRENCO has the experience of an accredited DAKKS conformity assessment body.
