Description

Technical Field

[0001] The utility model relates to the technical field of numerical control milling machines, in particular to a numerical control milling machine with a positioning fixture. Background Art

[0002] Milling refers to the use of a rotating multi-edged tool to cut workpieces. It is a high-precision processing method. During operation, the tool rotates (as the main motion) and the workpiece moves (as the feed motion). The workpiece can also be fixed, but at this time the rotating tool must also move (to complete the main motion and feed motion at the same time). The machine tools used for milling include horizontal milling machines or vertical milling machines, as well as large gantry milling machines. These machine tools can be ordinary machine tools or CNC machine tools.

[0003] Milling is generally performed on a milling machine or a boring machine, and is suitable for processing planes, grooves, various forming surfaces and special surfaces of molds, etc. However, when processing workpieces, existing CNC milling machines generally require manual adjustment and clamping, and the fixtures for clamping the workpieces are not stable enough, which affects the processing quality of the milling machine on the workpiece. For this reason, we propose a CNC milling machine with a positioning fixture to solve the above problem. Utility Model Content
