CNC Machining Parts

Machining is a material removing process to achieve accurate dimension tolerance and surface roughness. It is a manufacturing system that consists of workpiece material, cutting tools, and machine tools.  Nowadays, the machine tool has almost all computer numerical controls. As a result, the CNC machining efficiency increase dramatically.

Fundamentals of Machining

Machining cut material from the workpiece surface, the cutting tool creates a shearing deformation zone at the cutting area. The process produces waste chip, and raise zone temperature because of friction on the contact surface.

There exist three cutting parameters: cutting speed, feed rate, and cutting depth. Machining jobs will optimize these parameters according to the particular machining system adopted, this makes sure that perfect production efficiency is achieved.

Some common cutting process includes turning, slab milling, end milling, facing, cutting off, and so on.

Machining Process: Turning and Milling

Machining can be classified into two categories: turning and milling.

The turning process rotates workpieces on a lathe or similar machine tools typically while the cutting tool is working. Machine tools are highly versatile and capable of doing a number of machining processes to create a featured geometric profile. The finished workpiece is round or conic shape normally.

The milling process rotates the cutting tools to remove workpiece material, as well as travel along various axes with respect to workpieces. Once the computer numerical control system and driving servo added, milling operation is capable to make complicated parts with several axles moving simultaneously.

Field Application

Almost all industry sectors need precision machining components to meet accurate fitting requirements between assembly parts.

The automotive industry, such as piston ring, and Gas station fuel dispenser components, are typical machining components application cases.

To sum up, CNC machining is a precision manufacturing process, it is final downstream workmanship that can meet customer ultimate precision requirements.
