Design Tips
Machine grip faces 0.05–0.10 mm oversized if hard anodizing is specified — confirm allowance before drawing is locked.
Use thread inserts (Helicoil or Keensert) in aluminum jaw sets where repeated tool changes will stress threads.
Specify datum surfaces that must remain accessible for CMM probing in your drawing notes.
Call out gripping-surface flatness and parallelism separately from general tolerance block.
Featured Case Study
7075 Gripper Fingers for a Packaging Robot
Maintaining parallel gripping surfaces within 0.02 mm after hard anodizing — machining allowance, masked datums and agreed inspection method defined before production.
Prototype Robot Parts, Then Repeat Production
A robot cell usually starts with one part that has to fit today. The same drawing often becomes a repeat order once the cell is validated — so prototypes are machined on the production program from the first piece.
One piece to start
Prototype robot parts are machined from a single piece. There is no minimum order quantity, and setup is amortised over the batch you actually need.
What to send
A STEP model with a PDF drawing that identifies datums and critical interfaces. A detailed 2D drawing without a model is also enough to quote from.
DFM review before cutting
Every drawing is reviewed before the quote. Features that would add cost without adding function are raised before anything is machined.
Typical lead time
5-10 working days for standard batches once the drawing is confirmed; volume, material availability, finishing and inspection level move it.
Repeat production
Same part number, same program, same inspection level at any volume - a validated prototype can be reordered without a new approval cycle.
Documentation
Standard final inspection is included. Critical-dimension, full dimensional and FAI reports are supplied at the level agreed on the quotation.
