Machining Delrin: Tips, advantages & applications
Delrin is a polyoxymethylene (POM) thermoplastic used in machining applications for its excellent strength and high wear resistance. This material is also known by other brand names such as Acetal, Polyacetal, and Hostaform. It is typically used in applications that require high strength and stiffness with low friction, such as gears, bearings, bushings, and fasteners.
Delrin machining can be done with a variety of tools, including milling, turning, drilling, tapping, and grinding. However, there are important tips to keep in mind when machining Delrin. Here are some tips for successful Delrin machining:
– Use carbide tools with sharp cutting edges for best results.
– Use coolant or lubricant for the best surface finish.
– Use light cuts and high speeds for best results.
– Make sure tools are sharp and in good condition.
– Use a feed rate of 0.002” per revolution.
– Make sure to take into account the material’s thermal expansion.
These tips will help ensure successful Delrin machining and produce parts with the best quality surface finish. Additionally, Delrin offers several advantages compared to other materials. Here are some of the advantages of Delrin:
