  • Spindle Quills and Wheel Adapters Grinder Tooling GCH Tool

    GCH can custom design wheel adapters for any grinding wheel regardless of size. Spindle quills are offered in a host of lengths and diameters. Every quill and wheelscrew assembly is manufactured from standard steel or tungsten-based heavy metal to provide optimum density and rigidity for near "chatter-free" machine operation. Grinding machines like broaching machines operate over a range of speeds depending on the type of machine being used.These range from approximately 1250 to 2000m min −1 although in high-speed grinding speeds of up to 5400m/min are achievable (Schey 1987).The two most common grinding applications are cylindrical grinding and surface grinding.
