About This Part

This end head is a simple part that punishes sloppy turning: an acetal cone with a fine external profile, a threaded bore, and surfaces that show every chatter mark. We turn it from Acetron GP white POM bar in two operations, roughing the profile on a general lathe and finishing the critical features on a CNC lathe with the part reversed for a true second-end reference.

Dimensions follow an imperial drawing to ASME Y14.5: decimal features at X.X ±0.020 in and X.XX ±0.010 in, angles at ±0.5 degrees, and a 63 Ra microinch general surface. All internal and external edges are broken to 0.02 in and the 1-1/8-7 thread is cut to Class 2 so the mating ring seats smoothly without forcing.

Acetal brings high wear resistance, self lubrication, dimensional stability, and chemical resistance, which is why it appears on fluid and dosing equipment. Every piece is inspected for size and appearance, cleaned, and packed individually.

This part family supports the Industrial Parts industry. Read how KGL machines parts for that sector, then send your drawing for a quote.

Why Machine It at KGL

Five-Axis Fleet

100+ CNC machines including 11 five-axis centers run complex geometry in single setups, so tolerances do not stack up across refixturing.

Verified Accuracy

±0.005 mm standard on metals, plastics, and carbon fiber composite, verified on Hexagon and Zeiss CMMs (0.0015 mm accuracy).

Fast Prototypes

Engineering feedback with every quotation; prototype parts typically machined in 15 to 25 days.

One Supplier, End to End

Material sourcing, machining, heat treatment coordination, finishing, CMM inspection and export packaging under one roof.

Common Questions

Why acetal instead of nylon or PTFE for this head?

Acetal holds its dimensions better than nylon in humid service, machines into crisp thread forms, and keeps the stiffness that PTFE lacks. For a threaded end head that gets assembled repeatedly, it is the practical middle of the plastics family.

Can you run this part in imperial from a US drawing?

Yes, this lot was produced exactly that way, inspected against ASME Y14.5 callouts, and shipped with records. Send the drawing and we quote within 24 hours.

What is the minimum order?

One piece. Bar stock quantities allow us to support prototypes and volume from the same process.
