PROCESS FIT
Why mill-turn fits multi-feature parts
Mill-turn adds live-tool milling and drilling to turning, so round parts with flats, slots or cross holes need fewer transfers between machines. The drawing and tooling set the machining sequence.
Our production equipment
We operate 13 mill-turn machines in our own Dongguan factory. The equipment page lists their models and quantities.
Batch quantities
Trial runs from 200 pieces; production runs from 2,000.

Find the closest shape in the part collection and mention it in your inquiry. Block-shaped parts such as the housing are assessed case by case.
BATCH PLANNING
Compare batch quantities
At 2,000 pieces, each part carries 1/10 of the setup cost it would at 200. Your quotation shows the actual unit price for each quantity.

BUYER QUESTIONS
Questions about mill-turn production
What parts do you manufacture?
We make custom turned components with milled, drilled or threaded features. Shafts with flats, sleeves with cross holes and threaded parts with wrenching features are examples of the geometry we review. Our focus is complete mill-turn components rather than block-shaped milled parts, which we assess case by case.
Do you have your own production equipment?
Yes. We run 13 mill-turn and 16 Swiss-type machines in our own factory in Dongguan. View equipment
Can I compare several batch sizes?
Yes. Send one drawing revision and the quantity breaks you want quoted, so the quotations can be compared line by line.
What is your typical lead time?
Typical lead time is 15–20 days. Large batches or outside finishing can take longer; your quotation states the date for your order.
What tolerances apply if my drawing has none?
Tolerances on your drawing apply as drawn. For untoleranced dimensions we follow the general tolerance standard stated on the drawing; if none is stated, we work to ISO 2768-mK.
Do you make block-shaped parts?
Sometimes. Block-shaped parts are not our focus; we assess them case by case from the drawing.
