GMTA Hard Scudding

GMTA Presents Profilator and its “Micro-Finishing” Technology at Motion + Power Technology Expo

GMTA Hard Scudding Micro-FinishingWith over 300 exhibiting companies, the Motion+ Power Technology Expo is the ideal show for gear, electric and fluid power industries. Taking place between October 15 and 17, GMTA is one of the exhibitors at the Cabo Center in Detroit, Michigan.

GMTA will feature its Profilator line of gear pointing, rounding, cutting, Scudding®, Hard Scudding®, deburring and polygon machine tools for North America. The highly modular machines are used for polygon and slot facing, shifter stop machining, chamfering and deburring of highly complex automotive and other powertrain gears. The “Scudding®” and the “Hard Scudding®” process sets the Profilator apart in the market because of its manufacturing efficiency. “Hard Scudding®” allows the machining of green and hardened gears on the same machine, using the same programs. Furthermore, it is a superior technology to skiving, the previous technology used in the gear industry.

GMTA Hard Scudding Micro-FinishingWhile Profilator GmbH & Co. KG introduced the concept of “Hard Scudding®” in 2015, it expanded scudding technology with “Micro-Finishing.” “Micro-Finishing” takes place after the Hard Scudding® process has been completed. The process takes a high quality “Hard Scudding®” part and improves its surface quality. Additionally, this is a completely “dry” machining process and requires no cutting fluids or MQL technology. The total cycle time for finishing a ring gear via Hard Scudding® and “Micro-Finishing” is approximately 64 seconds but the cycle time could be decreased by 10%, keeping it under one minute for all automotive gear rings.

GMTA Hard Scudding Profilator Micro-Finishing Machine “Micro-Finishing” technology is aimed at making at quieter gear and the superfinishing process reduces friction, increases pitting resistance and the life of gears. This process uses a high quality diamond plated tool, designed to remove only a small amount of part material. The resulting part greatly increases surface quality on the gear teeth.

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.
