Abstract
Automatically adjustable stop for establishing limit of hydraulically powered axial advance for a milling spindle head with positive means for holding the spindle in fixed advance position during the milling operation along a plane normal to the spindle axis and with automatic gauging means for determining need for adjustment of stop position and gauge responsive means for automatically effecting such adjustment in the stop position while the spindle head is retracted from operating position.
Claims7
A machine spindle position control system for accurately adjusting from work piece to work piece the effective spindle head axial position and face cutting plane of a cutter comprising;
- a spindle head assembly mounted on a machine,
- bearings in said assembly supporting the said spindle head for axial movement,
- adjustable positive stop means coacting with an abutment surface rigidly associated with said axially displaceable spindle, said adjustable positive stop means being actuatable to establish the limit of spindle head advance to an effective fixed operating position preparatory to starting a machining operation on a given work piece,
- actuating means for axial advancing and retracting of said spindle head, and maintaining said spindle in advanced position established by said stop means,
- and means for adjusting said positive stop position, during retraction of and preparatory to advancing said spindle head axially for successive machining operations on successive work pieces.
