POM turning parts     Based on our experience in POM turning parts, POM materials have poor heat resistance and generate considerable heat during turning. Although cutting fluid provides some assistance, tool wear is still evident. High speed steel machine tools are not a problem, if it is made of ordinary POM material. However, some POM materials may add special materials such as fiberglass. POM turning parts What is POM? POM (Polyoxymethylene, or Polyformaldehyde) is a high-density, highly crystalline, non branched linear polymer. According to the different chemical structures in its molecular chain, POM can be divided into two types: homopolymer formaldehyde and copolymer formaldehyde. -Polyoxymethylene. The significant differences between these two types of POM are shown below. Homoformaldehyde has high density, high crystallinity, and high melting point, but poor thermal stability, narrow processing temperature range (about 10 ¡æ), and slightly lower acid-base stability. Co formaldehyde has low density, low crystallinity, and low melting point, but it also has good thermal stability, a wide processing temperature range (about 50 ¡æ), good acid-base stability, and is not easily decomposed. POM is an engineering plastic with excellent comprehensive performance. It has good physical properties, good mechanical properties, and good chemical properties, especially excellent friction resistance. POM is also the third largest general engineering plastic.
Raw Material of POM What can we do with POM? POM is suitable for manufacturing wear-resistant parts, transmission parts, chemical parts, and instrument parts. Due to its excellent stiffness and high friction resistance, POM is widely used in gears, bearings, automotive parts, machines, internal components and instruments.
POM Pulley Is POM suitable for turning? POM is suitable for turning, with an accuracy of up to 0.015mm. POM parts require precise machining by controlling feed and increasing speed. Based on our experience in POM turning parts, POM materials have poor heat resistance and generate considerable heat during turning. Although cutting fluid provides some assistance, tool wear is still evident. High speed steel machine tools are not a problem, if it is made of ordinary POM material. However, some POM materials may add special materials such as fiberglass.
Fiberglass enhanced POM DUPONT525GR Therefore, many POM turning parts suppliers will ensure high-performance tools. Such as diamond coated cutting tools, triangular ceramic slotting tools, hand grinding boring tools, etc. Some POM turning parts have high requirements for appearance or smoothness. After turning about 3000 POM parts with a hand grinding boring tool, the holes in the POM parts will appear pale. The drilling tool needs to be reworked, and the POM parts may turn black and shiny again.
