GMTA Now Represents WEMA Glauchau GmbH

The full line of WEMA grinding machines includes internal, universal, external, roller bearing, and customized solutions.

German Machine Tools of America is now the  North American distributor of WEMA Glauchau GmbH. These high precision grinding machines will be shown by GMTA at IMTS 2018.

WEMA 6SU Universal Grinding Machine

WEMA’s internal grinding machines maximize operating times with more efficient and integrated procedures. A repeatedly allocable tool and workpiece headstock are guided on up to six axes with an accuracy of 0.1 μm. WEMA SI is scalable and is adapted to the clients’ needs through specific mounting for the greatest machining efficiency. Powerful drives ensure quick availability with additional work and peripheral modules reducing costly non-productive times. Available in 4 different series (S2I, S3I, S6I and S10I), it offers machining of chuck and shaft-shaped parts. In addition, the internal grinding machines are equipped with internal cylinder/ cone, internal polygons, internal screw threads, up to 4 applicable grinding tools and high rigidity through the use of cast beds/hydropol beds.

With WEMA SU, universal grinding machines are available for the complex task of three-way machining of all major workpiece sizes. The machines are equipped with external and internal grinding units. Clamping operations provide decisive efficiency and precision benefits. WEMA’s technology enables machines to perform highly complex operations, while peripheral modules permit greater flexibility. These machines’ features include up to 3 swivel axes, machining of 4 sides in one clamping operation, machining of chuck and shaft-shaped parts and external grinding wheels with a maximum diameter of 600 mm. WEMA SU also offers additional features such as: 4 insertable internal grinding tools, 4 external grinding tools and cones, polygons, etc.

The company’s external grinding machines can machine parts up to 1,500 kg with external lengths of Ø  600 mm and 2,700 mm. Grinding wheels are available in Ø 500, 600, and 750 mm. Typical workpieces include railway axles, rollers, pipes and shafts.

Assemblies of the roller bearing grinding machines feature a strict modular structure used for various operations. One is for sequential internal, external and rim machining operations. Another is for simultaneous internal and external machining operations. Other modular structures are used for external machining operations, internal machining operations and rim machining operations. Machining jobs can be carried out on single or multi-row outer rings (OR) and inner rings (IR) of diverse bearing types. Notable features on these WEMA machines include three different types of milling centers (SW3, SW6, SW10), grounding of borings and tracks of inner rings, as well as tracks and outer diameters of outer rings. Outside rings have a diameter of approximately 300 mm to 900 mm. Shoulders, rims, etc can also be ground and different grinding operations can be performed in sequential or simultaneous grinding procedures.

Although the company’s grinding machines cover a wide range of possible applications,  they also build and design grinding machines to order ranging from more or less customized adaptations to complete designs of the machine.
