Questions buyers ask

01
Can you work from a 3D file?
Yes. STEP, STP, IGES, X_T and native SolidWorks files. The model is checked against the 2D drawing and anything that cannot be turned or measured is flagged before quoting.
02
Do you do a first article report?
Yes, on request. It lists every dimension on the drawing with the measured value, the instrument used and pass / fail.
03
What about surface treatment on turned parts?
Zinc, nickel, black oxide, anodising for aluminium, passivation for stainless. Anodising colour is matched to a sample you approve.
04
Can you keep the same tolerance across repeat orders?
Yes. The process sheet, tooling and inspection plan are filed per part number, so a repeat order runs on the same settings.
05
How do you pack small precision parts?
In a blister tray or a bag per cavity, with desiccant and a lot label. For high-value parts we pack into your line-side container.
06
Can a small lathe shop scale up?
Yes. First volumes run on CNC lathes; above roughly 50,000 pieces a year the same part moves to a cam machine, which brings the unit price down.
