What Type of Parts are Suitable for CNC Milling?

The main parts suitable for CNC milling are plane parts, curved surface parts, variable bevel parts, holes and threads, etc. For example, all kinds of cams, molds, connecting rods, vane, propellers and boxes. Also can carry out drilling, expanding, reaming, boring and screw machining.

Plane parts

Plane parts refer to the processing surface parallel or perpendicular to the horizontal plane, and processing surface and horizontal surface Angle is constant angle. Most parts belong to plane parts, is the most simple CNC milling processing of a part.

Curved surface parts

The processed surface is space curved surface. The machining surface of such parts can not be unfolded plane, general use spherical end mill cutting, processing surface and milling cutter is always point contact, if use of other tools easy to produce interference and milling injury adjacent surface. General use of three-coordinate CNC milling machine processing curved surface parts.

Variable bevel parts

The parts with continuous change of Angle between machining surface and horizontal surface are called variable bevel parts. Variable bevel parts are widely used in machinery and aerospace, such as beams, frames, edges strip and ribs on aircraft. For example, vane wheel, propellers, gears and turbine blades are variable bevel parts.

Because the variable bevel processing technology is complex, and the accuracy is very high, so the general machine tool is unable to process. Like this process complex, high precision parts, need to use precision five-axis machining center to process, ordinary three-axis machining center cannot process such parts, because ordinary three-axis machining center can only process plane and simple curved surface parts, the variable bevel parts can not be processed.
