Description

Technical Field

[0001] The utility model relates to a hydraulic fixture positioner, belonging to the technical field of positioners. Background Art

[0002] A milling machine is a machine tool with a wide range of uses. On a milling machine, plane (horizontal plane, vertical plane), grooves (keyway, T-slot, dovetail groove, etc.), tooth-dividing parts (gear, spline shaft, sprocket), helical surfaces (thread, helical groove) and various curved surfaces can be machined. In addition, it can also be used for machining the surface of a rotating body, inner hole and cutting work, etc. When the milling machine is working, the workpiece is installed on the workbench or attachments such as a dividing head. The rotation of the milling cutter is the main movement, supplemented by the feed movement of the workbench or milling head, and the required machined surface of the workpiece can be obtained. Due to multi-edge interrupted cutting, the productivity of the milling machine is relatively high. Simply put, a milling machine is a machine tool that can perform milling, drilling and boring operations on workpieces.
