Abstract
Grinding machine for a workpiece having a reference surface that cannot be used for mounting the workpiece for grinding and, yet, must be located near the abrasive wheel to permit accurate grinding of surfaces relative to the reference surface; the machine includes a chuck adapted to mate with a locating surface in a workhead and to mate with a similar locating surface in a mounting means, the mounting means including a clamp for engaging the reference surface on the workpiece and holding it in a fixed predetermined relationship to the locating surface on the chuck.
Claims3
Grinding machine, comprising
- a. a workpiece-holding chuck having a locating surface and having an open-ended container normally holding a low-temperature melting alloy in which a first portion of the workpiece is embedded with a second portion of the workpiece with a reference surface exposed on which the grinding operation is to be performed,
- b. a workhead and a wheelhead mounted for relative controlled movement to perform the grinding operation, the workhead having a locating surface for engagement by the locating surface on the chuck, and
- c. a setup head remote from the workhead having a locating surface exactly similar to the locating surface on the workhead and having a clamping means for engaging the said reference surface to hold the workpiece in the container in such a way that the locating surface of the chuck and the reference surface of the workpiece lie in a predetermined geometric relationship.
