CNC lathes can be used to process complex rotary body shapes. Milling is to fix the blank, with high-speed rotation of the milling cutter in the blank knife, cut the shape and characteristics of the need. Conventional milling is more commonly used for simple shapes/features such as contours and grooves. CNC milling machine can be used to process complex shapes and features. Milling and boring machining center can be three or multi-axis milling and boring processing, used for machining, mold, fixture, fixture, thin-wall complex surface, artificial prosthetic, blade and so on. In the selection of CNC milling processing content, should give full play to the advantages and key role of CNC milling machine.
A common cold working method of metal, differing from turning in that in milling the tool rotates at high speed driven by a spindle while the workpiece being machined remains relatively stationary.
The difference between turning and milling:
Turning is used to process rotary parts, the parts through the three-grasp chuck clamp on the machine tool spindle, and high-speed rotation, and then use the tool according to the busbar of the rotary body knife, cut out the product shape. The lathe can also carry out the processing of the inner hole, thread, biting flowers, etc., the latter two are low-speed processing.
The Processing Technology
(1) the curve profile of the workpiece, such as straight line, arc, thread or spiral curve, especially non-circular curve and list curve profile given by mathematical expression.
(2) The space curve or surface of which the mathematical model has been given.
(3) Although the shape is simple, there are many sizes and difficult parts to detect.
(4) it is difficult to observe, control and detect the inner cavity and the inside of the box body when processing with ordinary machine tools.
(5) holes or planes with strict dimensional requirements.
(6) A simple surface or shape that can be processed in a single clamping process.
(7) The use of CNC milling can effectively improve productivity, reduce labor intensity of the general processing content.
Suitable for CNC milling main processing objects have the following categories: plane contour parts, variable Angle parts, space surface contour parts, holes and threads.
