The invention provides a machining center for machining a workpiece by moving a grinding wheel and the workpiece relative to each other in the X, Y and Z directions. The machining center has a main spindle for removably mounting a grinding wheel, a spindle head for rotationally supporting the main spindle, a table for mounting the workpiece, a column for movably supporting the spindle head, and tool dressing means having a dresser spindle, provided over the spindle head to move in the vertical direction toward and away from the grinding wheel mounted to the main spindle, for mounting a dresser for truing or dressing the outer peripheral surface of the grinding wheel.

Machining center and method of changing tools thereof

The present relates to a machine tool for machining a workpiece by moving a tool and the workpiece relative to each other and to a pallet changer thereof. The machine tool is provided with a spindle for mounting the tool thereon, a table for a pallet (P) having the workpiece mounted thereon to be placed on the table, a pallet loading station for setting up the workpiece to the pallet (P) on the pallet loading station, and a pair of pallet change arms arranged to swivel about a vertical axis between the table and the pallet loading station, one pallet change arm ( ) of which is arranged to be able to move independently of the other pallet change arm ( ) in the vertical direction.

Machine tool and its pallet changing device

The present invention relates to a machine tool system and a machining liquid supply device for machining a workpiece by a tool such as a grinding wheel or a milling cutter, and solves the problem of how to supply the machining liquid optimally to an area where the tool engages with the workpiece. In order to solve this problem, the present invention is so configured that during the machining of a workpiece with a tool (T) detachably mounted on a spindle ( ) of a machine tool (MT), the machining liquid supply device ( ) for supplying a machining liquid to a machining area of the tool (T) is provided with an opening end at the forward end of a machining liquid supply nozzle ( ), and can give the movements in a radial direction and a circumferential direction through 360&deg; with respect to the axis of the spindle ( ) about the spindle head ( ) having the spindle ( ) through a rotational supporting body ( ) by means of linear movement means ( ) and rotating movement means ( ), respectively.
