Computer Numerical Control (CNC) Machining is a manufacturing process in pre-programmed computer controls that controls the movement of machinery and factory tools. This means that complex machinery like grinders, mills and routers are dictated by computer software with a single set of commands.
In CNC machining, the software is programmed according to cuts required and dictates the actions of the necessary tools and machinery. In this way, the specified tasks are carried out by machines just like robots as the programs or codes in CNC are written by programmers and then fed to computers.
Plastic CNC Machining
Besides metals, plastic is most commonly used in CNC machining. Plastic CNC machining utilizes a variety of plastics to serve the interests of aerospace, energy, medical and oil industries. The types of plastic used in CNC machining are as follows.
Acetal
Acetal plastic is a thermoplastic that has a myriad of characteristics including wear resistance, low sensitivity to moisture, chemical and solvent resistance, good electrical properties, and high strength and toughness. It is used in gears, bearings, and engineering parts.
Nylon
Nylon in the form of rods, sheets, and tubes is used because of its toughness, high fatigue strength, abrasion resistance, solvent resistance, and durability. Its applications include power engineering, mechanical engineering, gear manufacturing, and various applications within the automotive industry.
Ultra-High Molecular Weight Polyethylene (UHMWPE)
This lightweight plastic has high abrasion resistance, good chemical resistance, outstanding impact strength, little to no moisture absorption, and noise resistance, so it is commonly used in shipping, the handling and storage industry, farm machinery, the forestry industry, and the chemical and biological treatment industry.
PVC
Polyvinyl chloride is a synthetic plastic polymer with high chemical resistance, good mechanical properties, and high purity. It is easy to machine and is typically used in chemical plant engineering, semiconductor technology, and chemical technology.
Applications of Plastic CNC Machining
Today, plastic CNC machining is being used to produce prototypes of equipment in almost every field of life. Some of the industrial applications of Plastic CNC Machining include:
- Biomedical and pharmaceutical devices
- Chemical handling equipment
- Food handling components
- Laboratory and scientific equipment
- Microelectronics
- Photonics
- Semiconductor components
First Part CNC Machining Service
First Part Co. employs cutting edge technology and a variety of CNC machining processes to attain complex three-dimensional cutting jobs with accuracy and efficiency.
First Part CNC machining service uses following operations for the production of parts.
CNC Turning and Milling
Turning is a machining process where the product is removed from a rotating workpiece using single point cutting tools. This is a subtraction manufacturing process where the raw material is rotated and another metal rod is dictated to subtract material from the rotating rod to get the required product. This process produces parts with radial holes, grooves, slots, and cylindrical features.
CNC Milling
Milling machining employs multi-point cutting tools to remove material from a rotating workpiece. The cylindrical rotating tool removes excess material as it moves along multiple axis. CNC Milling produces jigs, fixtures, 3D shapes and complex parts in a short period of time.
First Part strives to deliver reliable service on-time, and quality control is always a prime concern of theirs, so they always design products with practical and functional utility. These characteristics of the First Part CNC machining service them the first choice for customers.
Conclusion
Cutting edge technology has replaced manual machining with programmed machining that can be pre-programmed to dictate machinery to create a certain product. Computer Numerical Control (CNC) Machining is a prime example of this. Consequently, CNC machining is influencing every field of life from home appliances to medical and aerospace equipment.
