POM (Polyoxymethylene) Is Widely Used In CNC Machining To Manufacture High-Precision, Low-Friction And Wear-Resistant Mechanical Parts, Such As Gears, Bearings, Bushings And Precision Fixtures. This Material Has Excellent Dimensional Stability And Chemical Inertness. When Processing, Sharp Carbide Tools Must Be Used, Cutting Speed And Feed Rate Must Be Reasonably Controlled, And Compressed Air Cooling Must Be Used To Prevent Thermal Deformation. Its Low Moisture Absorption Property Reduces The Risk Of Deformation After Processing, But Chip Removal Must Be Paid Attention To To Avoid Material Melting. It Is Suitable For Medical Equipment, Automotive Accessories, Electronic Components And Other Fields That Have Strict Requirements On Tolerance And Surface Finish.

Available POM at Dazao: Homopolymer POM, Copolymer POM etc.
Homopolymer
POM
Made From A Single Formaldehyde Monomer, It Has High Crystallinity, Better Mechanical Strength, Rigidity And Hardness Than Copolymer Formaldehyde, But Slightly Worse Thermal Stability. It Is Mainly Used In High-Load Gears, Bearings, And Precision Structural Parts.
