CNC Machining Manufacturable Precision Parts

CNC machining is a very convenient and efficient manufacturing technology that uses computer numerical control (CNC) technology to control machines and tools that process various materials and items.

Most machining materials can be used on CNC machines. It really depends on the application. Common materials include metals such as aluminum, brass, copper, steel, and titanium, as well as wood, fibers, and plastics such as polypropylene, [**]BS, POM, PC, and nylon. But some materials are too soft or too hard to be machined on a CNC machine. For example, materials such as rubber or silicone are too soft for CNC machining, while ceramics are too hard for precision machining.

1. Common use of CNC precision machining parts

Using CNC technology and a variety of tools, almost anything can be manufactured on a CNC machine, from marine parts, mechanical parts to aerospace parts, which are often high-precision parts, including shafts, gears, bushings, flywheels, cams, dies , propeller, etc. The products that can be produced on a CNC machine depend on the type of machine used. Each type of CNC machine has its own machining capabilities to manufacture unique part properties. For example, round or spherical parts produced on a CNC turning center cannot be produced on a CNC milling machine, and parts produced with a milling machine cannot be produced with a CNC lathe, etc.

2. Products that can be machined by turning CNC precision parts

In the CNC machining industry, CNC lathes are used to process linear cylinders, inclined cylinders, arcs, and various threads, grooves, and worms. They can also handle complex surfaces of revolution, such as hyperboloids. Typical CNC turned parts include shift knobs, knobs, pulleys, shafts, hubs, bushings, flywheels, and more.

3. CNC precision parts can be processed by milling

CNC milling machines are mainly used to process various complex planes, curved surfaces and shell parts, such as various cams, molds, connecting rods, blades, propellers, boxes, shell parts, etc. CNC milling. To sum up, typical CNC milling parts can be divided into three categories: flat parts, curved parts and angle steel parts. Each machine has its own precision class and machining sequence. Sometimes, some machining equipment is used to make certain parts.

So what is more difficult to CNC machining?

1. Most parts can be manufactured on CNC machines, but there are some limitations. Parts with certain features that are not suitable for CNC machining include:

Inner vertical angle

Since CNC milling cutters are cylindrical in shape, they leave a radius of vertical angle when cutting the inner wall. While it is possible to reduce the diameter of the nose by using a smaller diameter tool, no matter how small the tool diameter is, the internal vertical angle cannot be formed.

2. Thin-walled precision parts

It is difficult to process thin walls, and it is easy to deform or break during CNC machining. Thin-wall machining requires multiple passes at low depths of cut, and thin features are also prone to vibration, making precise machining challenging and increasing machining time.

3. Precision parts with notches

Since the tool can't get there to do any machining, it's difficult to CNC make some cuts in the inner wall of the part.

Therefore, it is recommended to avoid using these functions before designing CNC precision part machining.

CNC machining provides precise cutting and manipulation capabilities, and it can be said that most products made of wood, metal, aluminum, alloys, and various other materials can be completely constructed or improved by using CNC machines. The above are the precision parts that can be manufactured by CNC machining introduced by CNC precision machining parts manufacturers.
