Grinding quills
20 May 2014
Master Abrasives has created a general overview of the importance of grinding quills for precision internal grinding.
Most engineers involved in grinding understand what a grinding quill is, but few actually consider the important contribution the quill can make when optimising the abrasive machining processes, claims Master Abrasives.
When assessing an internal grinding operation, abrasive technicians turn their attention to such things as feeds & speeds, abrasive wheel shapes and specifications, dressing options and appropriate coolant choices, however quills seem not to merit much consideration.
This can be an oversight, because, like other grinding process variables, quills have an important role to play. Selecting the right quill for the job can make an important difference to the process optimisation and achieving your 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.
