摘要:
A machining center includes a rotatable tool magazine (22) arranged above a work space (WS) facing a spindle (15) tilted so that the spindle side becomes lower and having a plurality of grippers (24) for holding tools (16) in a circumferential direction, and a shutter (26) arranged below the tool magazine (22) to be able to open and close facing the spindle side. The tool magazine (22) has a tool-free area (AR2) where there are no grippers (24) at a part of the circumferential direction and a tool-holding area (ARA) where there are grippers (24) at another part of the circumferential direction. The tool magazine (22) is controlled in rotation so that when the shutter (26) is closed, the tool-free area (AR2) moves to the spindle side while when the shutter (26) is open, the tool-holding area (AR1) moves to the spindle side.

A clamping device (1) for a machine tool (2) for machining at least one dental workpiece (3), wherein the clamping device (1) has at least one workpiece carrier (4) for accommodating the dental workpiece (3) during machining, wherein at least one tool holder (5) for holding at least one, preferably a plurality of cutting tools (6) for machining the dental workpiece (3) is arranged, preferably fixedly, on the workpiece carrier (4), and the workpiece carrier (4) and the tool holder (5) are fastened or fastenable together as one component on a carrier of the clamping device (1) in an exchangeable manner by a fastening device (7) that is non-destructively releasable, preferably without a tool.
摘要:
A rotary drive adapted to perform a speed of rotation switching of a tool holding device, comprising an output drive shaft bearing the tool holding device, said output drive shaft being able to be moved into first and second axial positions by means of a setting drive. The output drive shaft is coupled in the first axial position with a power driven first drive gear wheel and in the second axial position with a concentric tubular shaft, which is adapted to be driven by a power driven second drive gear wheel by way of a worm drive.

摘要:
An automatic tool-replacement apparatus including the main body of a machine tool on which a plurality of tools can be dismountably mounted. The tools are selectively held by an automatic tool-replacement arm and are mounted on or dismounted from the main body. The arm has a plurality of holding portions for holding the tools. Therefore, a plurality of tools can be mounted on or dismounted from the main body of the machine tool by one-time operation of a single arm. Each holding portion has a pawl for preventing disengagement of the tool positioned therein, this pawl being able to advance toward and retract away from the holding portion.
摘要:
A machine tool has a rotating head provided with a radially movable carriage. Transferrable tool holders are clamped to the carriage of the head by a releasable clamping mechanism. A plurality of tool holders are held on an indexable drum, the rotational axis of which lies perpendicular to the axis of rotation of the head. The tool holders are slidably transferred from the drum to the carriage of the head and vice versa by a changer which has a transfer rod and a mechanism for actuating the clamping mechanism.

A MACHINE TOOL WITH AUTOMATIC TOOL CHANGING IS DESCRIBED WITH A TOOL HOLDER HAVING A CENTRAL TIGHTENING SCREW AND LOCK AND A FACE SLIDE INCLUDING AN INDEXING PIN AS WELL AS TWO COMPRESATING WEIGHT THREADED SPINDLES.
摘要:
The present invention provides a tool changer which can be placed on the table of an existing machine tool, while utilizing the existing control computer of the machine tool to automate the tool changing process. This simplified tool changer allows the owner of an entry level machine tool to automate the machine tool at a relatively low cost and without many modifications to the machine tool as compared to current alternatives. The tool changer of the present invention requires no external power, no additional motors, and no modifications to the spindle of the machine tool.
摘要:
Automatic cutter change type shaving machine, wherein a spindle of a cutter head supported movably upward and downward by a column has a cutter loading portion having a mechanism to load and unload a cutter along the axis of said spindle at an end of said spindle and a carriage which moves toward and away from said cutter loading portion carries out load and unload of a cutter for said cutter loading portion through its reciprocating motion.
