About This Part
At 431.8 mm long and slender, this blue POM rail is a material behavior problem as much as a machining one. Acetal releases stress as you cut it, so the channel and window are roughed and finished in staged passes on vacuum fixturing, holding the overall length at plus or minus 0.010 in and the channel geometry at plus or minus 0.005 in.
The half enclosed round channel runs the full length for flow or cable guidance, with a center through window along the rail. The ends carry precision locating bores and cutouts at Ø1.505 plus or minus 0.002 in and Ø1.872 plus or minus 0.001 in, positioned at .008 and .010 in to datum A, so rails splice cleanly on long tracks.
Chip control is the other half of the job: POM packs heat and the deep channel hides burrs. Sharp geometry, controlled engagement, and a full length deburring pass keep the channel clean. The gantry CMM checks length, bore positions, and channel straightness end to end.

Common Questions
Why POM for a 17 in rail?
Low friction, low wear, and quiet running against product contact parts. The cost is stress movement during machining, which staged symmetric passes and vacuum fixturing keep ahead of.
What fails on long plastic rails?
Burrs packed into the channel and heat distortion. Sharp tools, cold engagement, and a deburr pass designed for the channel geometry deal with both.
