About This Part

Long plastic parts punish sloppy shops. At 66.19 in (about 1681 mm), this ERTALYTE TX bar would bow at the first aggressive cut if residual stress and clamping force were left unmanaged. We saw the bar on a vacuum table on a large gantry machining center, finished the base face and datum edges first, then took the five precision square slots in light passes so the span between them stayed inside a two thousandth of an inch band from end to end.

The slots at 2.607 +0.000/-0.002 in carry the locating duty for the rotary piston mechanism, and the 1.643 +0.002/-0.000 in spacing between them is what keeps the mechanism phased. Thickness is 2.245 +/-0.002 in, parallelism holds at 0.002 in, and unmachined surfaces run at 32 Ra. End steps and the R2.495 radius transitions are cut in the same setup.

ERTALYTE TX cuts with a gummy, stringy chip and leaves fine burrs along milled edges, so every edge goes through hand micro deburring under magnification, then an ultrasonic cleaning pass. Before packing, the full length is swept on a gantry CMM, one piece at a time, with laser interferometry supporting the long span check.

Common Questions

How do you keep a 1.6 meter plastic bar straight?

Stress relief starts with the stock. We finish the datum face first on vacuum fixturing so the part is never clamped hard over the long span, then take the slots in light passes. Parallelism is verified with a full length CMM sweep, not a spot check at one end.

Why ERTALYTE TX instead of POM or nylon?

The solid lubricant filler gives it a lower friction coefficient and better wear life than unfilled PET or POM in sliding contact, which matters for a piston mechanism running continuously. It also holds its dimensions better in service.

Can you hold the slot span tighter than 0.002 in?

Tell us the target. The gantry platform and interferometer support tighter bands; the practical limit depends on the slot depth and the bar temperature during measurement, and we will confirm feasibility with the drawing in front of us.
