Burr-Free Grinding Machines

Providing a burr-free solution for grinding the teeth in arthroscopic shavers, the SG-1645 and SG-2060 Burr Free Electrochemical Surface Grinding machines cut shaver teeth burr-free, without recast, slag or heat damage, and much shorter cycle times. The machines are designed for burr-free grinding on applications with tight tolerances on stainless steel and other heat-sensitive materials.

Arthroscopic shaver teeth are commonly produced by conventional abrasive grinding, wire EDM, or laser cutting which are slow processes resulting in long cycle times. EDM and laser cutting burn away the metal at high temperatures leaving changes to the metal surface including heat-affected zones, recast, and slag. Laser cutting requires significant post-processing to produce an acceptable sharp edge and surface finish. Conventional grinding requires a secondary process of deburring without damaging the cutting edge. It also involves frequent wheel dressing to maintain the correct form and a high-quality part.

Each machine features CNC controls and high precision components for high accuracy and repeatability. The optional pallet loader features a 180-deg. index table allowing parts to be loaded during the grinding operation, reducing loading time to almost zero, and maximizing productivity.

All Tridex machines feature safety rated door interlocks, servo systems, and pneumatics and are certified to CE and the ISO 13849 Machine Safety Standard
