Abstract: A workpiece spindle comprises a spindle, a spindle motor and an actuator. The spindle is dynamically connected to the spindle motor and has a first channel and a second channel connected to the first channel. The first channel is assembled with a lathe center, the actuator is provided with an actuating rod disposed outside the spindle corresponding to the second channel. The workpiece spindle limits rotation of the spindle by displacing the actuating rod of the actuator by a first actuation distance relative to the second channel, and the workpiece spindle drives the lathe center to displace in the first channel by displacing the actuating rod of the actuator by a second actuation distance relative to the second channel. Thereby, machining statuses of the lathe center are integrated for convenient operation, and the lathe center is driven and displaced in the channel to facilitate replacement.

Abstract: A honing machine (100) for honing a bore in a workpiece comprises a support structure (120) fixed to the machine and at least one honing unit (130) which is mounted on the support structure and which has a main support (160), which can be mounted fixedly in relation to the support structure, and a spindle unit (150), which is supported by the main support and in which a spindle shaft (152) is rotatably mounted, wherein the spindle shaft (152) is rotatable about a spindle axis (155) by means of a rotary drive and, at a tool-side end (153), has a device for the fastening of a honing tool. The honing machine furthermore has a linear guide system which is arranged between the main support (160) and the spindle unit (150) and which serves for guiding a linear stroke movement of the spindle unit (150) relative to the main support (160), a stroke drive for generating the stroke movement of the spindle unit (150), and an alignment system (200) for setting the alignment of the spindle axis (155) in relation to the support structure (120). The alignment system (200) is designed for the continuously variable, reversible setting of the alignment of the spindle axis (155) in relation to the support structure (120), wherein the alignment system is designed for the independent setting of the position of the spindle axis (155) along two mutually perpendicular axes of translation and for the setting of the orientation of the spindle axis (155) in relation to two mutually perpendicular axes of rotation.

The body has a driving shaft rotatably disposed in the body and a containing hole disposed through a side of the body. The extension shaft has two ends and a concave structure. One of the two ends of the extension shaft is connected with the driving shaft of the body. The concave structure is disposed on the extension shaft, and is aligned with the containing hole of the body after the extension shaft rotates with the driving shaft. The nut is mounted on the other one of the two ends of the extension shaft. The button assembly is mounted in the containing hole of the body, and is able to be pressed and to extend into the concave structure to restrict the extension shaft from rotating.

Abstract: A device for grinding and deburring a flat workpiece comprise a grinding roller having an abrasive coating. A coaxial drive shaft that is connected rotation-fast to the guide roller is driven by a drive motor via a primary belt drive. The grinding roller is borne axially displaceable on the drive shaft. Via a second secondary belt drive, the drive motor drives a cam mechanism, comprising a control cylinder that is rotatably borne on the drive shaft of the grinding roller and that has a groove cam and comprising a cam slide arranged on the grinding roller. The rotating grinding roller thus performs an oscillating axial back-and-forth movement.

Abstract: The present invention is an original direct motor-drive portable angle grinder with a disc type motor installed in a position adjacent to the grinding wheel and an outer motor rotating part coaxially and directly driving the grinding wheel. By means of the direct drive, the present invention prevents the emission of noise made by angle type transmission devices. Moreover, an inertial body is installed on the rotating housing that is integrated with the rotating part to form a flywheel or the rotating housing and the inertial body are integrated into a single reinforced structure to enable a flywheel function in order to improve the grinding, polishing and machining or cutting abilities of the grinding wheel.
