    How to operate CNC Milling?

     

    Milling fixes the blank and uses a high-speed rotating cutter to advance the blank and cut out the desired shape and features. Traditional milling is used more for simple profile features such as milling profiles and slots. CNC milling machines can handle complex shapes and features. The boring and milling machining center can perform three-axis or multi-axis boring and boring machining for machining, dies, gauges, lathes, thin-walled complex surfaces, artificial prostheses, blades, etc. When selecting CNC milling processing content, the advantages and key functions of the CNC milling machine should be fully utilized.

     

    CNC milling is a common metal cold processing method is different from turning in that the tool rotates at a high speed under the drive of the spindle in the milling process, and the processed workpiece is relatively stationary. The difference between turning and milling: Turning is used to machine the rotary part. The part is clamped on the spindle of the machine by a three-jaw chuck, and it is rotated at a high speed. Then the tool is used to cut the product shape according to the busbar of the rotary body. Come. Lathes can also be machined for bores, threads, biting flowers, etc. The latter two are low-speed machining.

     

    Parts Of CNC Milling.jpgBefore operation, check whether the components and safety devices of the CNC milling machine are safe and reliable; check whether the safety and reliability of the electrical parts of the equipment are good. When loading or unloading the workpiece, the table should be retracted to a safe position. When tightening the workpiece with a wrench, the CNC milling cutter should be used in the direction of force to prevent the wrench from colliding with the tool or jig. When CNC milling irregular workpieces and holding workpieces with vises, indexing heads and special fixtures, the center of gravity of irregular workpieces and vices, indexing heads, special fixtures, etc. should be placed as far as possible on the middle of the worktable to avoid the workbench. Uneven stress, resulting in deformation. For the CNC milling machine, pre-selection of the work program, spindle speed, tool feed amount, tool movement path, and consecutive offside position should be performed before the work according to the process requirements. Place the electric knob in the “adjusted” position to test the car. After confirming that there are no problems, place the electric knob in the automatic or semi-automatic position to work.
