Gear Expo Preview: Emuge Corp Booth 505
August 15, 2013
Emuge Corp., a manufacturer of precision workholding devices for many industries, offers a comprehensive line of clamping solutions. Emuge’s workholding division specializes in providing highly accurate, almost maintenance-free customized solutions for applications from low volume job shops to high volume automotive production environments. “Our workholding group stays close to our customers to learn about their unique challenges and production environments. Doing so helps us develop the best solutions for their applications,” said David Jones, precision workholding manager at Emuge Corp.
With its expanding-bush design, Emuge’s System SG is used in many machining operations such as hobbing, shaping and shaving for gear production, as well as milling and inspection. The System SG’s large surface area contact with the workpiece provides a clamping solution which is very rigid, accurate and repeatable.
The high precision System SP is used not only to clamp workpieces but also to clamp tools. By applying an axial force, the clamping sleeves move in the direction of the force and expand radially. This eliminates the clearance between clamping sleeve and body, and between clamping sleeve and workpiece. System SP achieves concentricity of < 0.002 mm (corresponding to < 0.0001 inch).
For workpieces that have a short clamping base or for diameters with a very large tolerance, Emuge offers the System SZ. By applying an axial force, a slitted collet is radially expanded by a cone. Simultaneously an axial movement occurs, clamping the workpiece.
When the eccentricity between pitch circle and seating bore is very small, diaphragm clamping System SM is suitable. It allows clamping of the gear wheel at the pitch circle for machining the seating bore. The gear wheel is clamped in both axial and radial directions.
System SH is a solution if there is not enough room for a mechanical clamping system and for clamping long, thin-walled workpieces or a number of similar workpieces. System SH is a closed system which uses hydraulic pressure to clamp the workpieces.
