Grinding quills
07 July 2014
Master Abrasives is highlighting the importance of grinding quills for precision internal grinding. Selecting the right quill for the job can make an important difference to the process optimisation and achieving grinding process objectives.

The purpose of the quill is to position the wheel into the part to reach the surfaces you need to grind. It is a highly customised and tightly toleranced tool that serves as an extension of the spindle itself.
It would not be economical for spindle manufacturers to produce thousands of different spindle designs to reach into every possible interior geometry. Instead, they produce a single design with a standard interface to which customers can design quills to suit their individual requirements. A well-designed quill should have a long lifespan, allowing the user to mount grinding wheels to it numerous times.
