Common metal CNC machine additionally provided with high-speed spindle and application method thereof

Abstract

The invention relates to the technical field of CNC processing and discloses a common metal CNC machine additionally provided with a high-speed spindle and an application method thereof. The common metal CNC machine additionally provided with the high-speed spindle comprises a four-shaft workbench, a fixture, an original spindle and a tool magazine which are arranged on a machine base. The four-shaft workbench is located below the original spindle. The fixture is mounted on the four-shaft workbench. The tool magazine is located above the original spindle. The tool magazine is used for clampingand carrying a plurality of different sizes of cutting tools. The original spindle is provided with a high-speed spindle fixing bracket. The high-speed spindle fixing bracket is provided with the high-speed spindle. The fixture is used for clamping and fixing a workpiece to be processed. The high-speed spindle grabs and clamps the corresponding cutting tool from the tool magazine to implement processing on the workpiece. The four-shaft workbench drives the fixture clamping the workpiece to do four-shaft motion relative to the high-speed spindle. The effects that an existing common metal CNC machine is used for processing plastic outer parts or plastic-metal combined parts and improves the processing yield are achieved. The common metal CNC machine additionally provided with the high-speedspindle has the advantages of high processing efficiency and low invested cost.

Description

technical field [0001] The invention relates to the technical field of CNC machining, in particular to an ordinary metal CNC machine equipped with a high-speed spindle and a method for using the same. Background technique [0002] At present, there are usually three types of appearance structural parts of consumer electronics products such as smartphones: metal appearance parts, plastic appearance parts and plastic-metal composite parts. Metal appearance parts are usually formed by ordinary metal CNC machining, plastic appearance parts are injection molded by injection molding machines, and plastic metal composite parts are molded by die-casting aluminum alloy or magnesium alloy middle plates through in-mold inserts. Holes such as button holes, USB holes, earphone holes, and speaker holes on plastic appearance parts and plastic-metal composite parts are usually formed by CNC machining. [0003] The mainstream CNC models used to process metal appearance parts of consumer ele...

Problems solved by technology

[0007] The purpose of the present invention is to provide a common metal CNC machine equipped with a high-speed spindle and its use method. Its main purpose is to use a common metal CNC machine to add a high-speed spindle to further improve the processing yield while ensuring higher processing efficiency. It will not involve a large cost input, so as to solve the problem of processing the four side holes of plastic appearance parts or plastic metal composite parts, the processing yield is low when using ordinary metal CNC machining, and the processing efficiency is low when using plastic CNC machining , the use of ultra-high-speed metal CNC machining has the technical problem of high investment cost
