Pocket DepthAvoid unnecessarily deep pockets to reduce tool deflection and cost.
Thin WallsConfirm wall thickness based on material, part size and tolerance.
Hole DepthProvide depth and thread requirements clearly in drawings.
ThreadsSpecify thread standard, depth, tolerance and inspection requirements.
TolerancesApply tight tolerances only where function requires them.
Surface FinishDefine visual and functional finish requirements separately.
DatumMark datum and critical-to-function dimensions clearly.

FAQ

What plating options are used for CNC machined parts?

Common plating options include electroless nickel, zinc, tin and other project-specific coatings depending on material and function.

Does plating affect tolerances?

Yes. Plating thickness can affect threads, holes, slots and mating surfaces. Critical areas should be marked on the drawing.

Can steel CNC parts be zinc plated?

Zinc plating can be reviewed for steel components when corrosion protection and appearance requirements are specified.

Can copper or brass parts be plated?

Yes. Nickel, tin or other conductive/protective finishes can be reviewed by project requirement.

What should I include in a plating RFQ?

Include material grade, plating type, coating thickness if required, masking areas, critical dimensions, quantity and certificate needs.

Can plating certificates be provided?

Surface treatment certificates can be provided according to project and supplier documentation requirements.
