March 2014—29 Compact Drawbar Enables Power-Off Clamping Advanced Machine & Engineering offers the OTT-Jakob power drawbar for toolholding. Designed for power-off clamping in a compact design with minimal rotating mass, the drawbar is said to provide increased spring force while requiring lower tool-release force. According to the company, there is no load on the spindle bearings during tool change. The cutting tool is held securely in the spindle taper with gripper fngers, which are pulled into the taper with the spring pack of the power drawbar. The pull-in force is multiplied by an intensifying mechanism, and the spring force applied to the clamping sleeve pushes the balls outward. The angle design of the clamping ring Gear Inspection System Includes Surface Finish Measurement Gleason's 1500GMS analytical gear inspection system is said to enable faster inspection speeds and is capable of a range of inspection tasks for gears ranging to 1,500 mm in diameter. The updated inspection system now includes surface fnish measurement as part of the gear inspection process, avoiding the need to take the procedure offine to dedicated equipment. The system is capable of inspecting multiple traces on gear teeth using a motorized rotary probe system adapted to the existing SP80H scanning head. A range of surface fnish inspection parameters can be specifed, with programming for the operation incorporated into the system's GAMA applications software. Barkhausen noise testing can detect grind burn during the course of normal gear inspection, and Stresstech Rollscan 300 Analyzer technology is integrated into the platform to save time and setups. The system also supports non-gear metrology through the Gleason-Capps prismatic measurement software platform, making it well-suited for inspecting both gears and other rotationally symmetrical workpieces requiring high accuracy. The system is suitable for inspecting features such as bolt-hole patterns, tapered bores, diameters and lengths. The option is available in three levels ranging from self-taught routines to full CAD-based programming from 3D models.

The cam inside the spindle closes the gripper fngers to securely lock the tool, and according to the company, the tool will not come loose if there is a loss or reduction in hydraulic pressure. The power-off design requires pressure applied to the hydraulic piston and transmitted through the rod to push the clamping sleeve down to unlock the mechanism. After clearing the cam, the gripper fngers open and the face of the holder ejects the tool with a controlled stroke.
