What Is Teflon Machining?
Teflon Machining is the precision machining of customized Teflon parts cutting or forming through five-axis, milling, and turning by digital equipment. As one of the most popular plastic materials, PTFE is softer than POM, and it is easier to meet the needs of Teflon manufacturers to complete the cutting process. At the same time, Teflon processed parts have good corrosion resistance and are not affected by the chemical environment. After processing technologies such as turning and milling, Teflon parts can be in harsh environments for a long time.
Technologies Of Teflon Machining
-
Teflon 5-Axis MachiningThe 5-axis of motion of the CNC equipment is processed at different angles to produce high-precision Teflon pieces to meet the needs of PTFE manufacturers for customizing PTFE parts.
-
CNC Milling TeflonIt is a material removal process for milling CNC machine tools to perform irregular or curved processing of Teflon rods and sheets. Milling PTFE is efficient and fast at producing parts with tight tolerances.
-
Turning TeflonIt is the technique used by turning machines to perform material removal machining on Teflon parts. The rotary tool of the turning machine tool is more advantageous for processing cylindrical or round Teflon machining parts and can achieve high-precision processing.
-
Teflon DrillingWe provide Teflon drilling technology. The material of Teflon is soft and flexible, and the processed parts are not easy to deform. But it should be noted that when punching holes, we need to fix the tool to avoid skewing. Smallest drill hole size up to 0.5mm (0.02 in)
Properties Of Teflon
High-Temperature Resistance
Teflon material with a melting point of about 327 degrees Celsius, its processed parts can withstand high-temperature environments without being dissolved.
Corrosion Resistance
Teflon does not react to chemical solvents, so it will not corrode in chemical environments.
Low Coefficient Of Friction
Because Teflon has long linear polymer chains, its surface reduces contact with other surface areas, reducing friction.
Electrical Insulation
Teflon is an electrically insulating material with high dielectric strength and low dielectric constant, so it can withstand high voltages and does not conduct electricity.

Teflon Surface Finishing
Surface Finishing deburring is also a crucial step in a complete product. A perfect product must meet the tolerance requirements of customers, and at the same time, the surface is clean and free of scratches, and then the product is deburred. This step improves the level and quality of the entire product.
Industry Application Of Teflon
Aerospace Industry
For industries that require excellent high-temperature resistance, Teflon components are just right. Its component applications include bearings, bushings, and washers.
Automobile Industry
Teflon components with low friction properties have many applications in the automotive industry. Its applications include fuel lines, injector seals, and fuel tank linings.
Chemical Industry
Because Teflon does not react to many chemical solvents, it becomes a part of chemical equipment. Its component applications include pumps, valves, and reactors.
Electronics Industry
Electronic components require good electrical insulation and thermal performance, so Teflon components are often used in the electronics industry. Its applied parts are circuit boards, semiconductor manufacturing, and electrical connectors.
Teflon Grades For Teflon Machining
The material is a kind of Teflon material, which has good wear resistance. Its applications include seals, bearings, and electrical components. The advantage is strong chemical resistance. The disadvantage is that the price is relatively high and the machinability is poor.
The Teflon material has good flexibility and electrical insulation. Its applications include wires, seals, and gaskets. The advantage is better flexibility. The disadvantage is that it has low strength compared to other materials.
This grade of Teflon material has excellent non-stick properties. Its applications include coatings, linings, and tableware surfaces. The advantages are good chemical resistance and non-stick properties. The disadvantage is that it has poor temperature resistance and strength compared.
