*Additional notes on tolerance:
We will follow strictly the tolerance requirements indicated on the drawings, and for unspecified tolerances, ISO 2768 -mK will be applied by default.
Normally, CNC milling and turning is available for the tolerance of 0.01 mm, for the tolerance of 0.005 mm, grinding is necessary.
DFM For Precision Machining
Avoid Excessive Deep Holes
The effective cutting edge length of the milling tool is limited, and the right design of the hole depth help reduce the machining time and machining cost.
Limit thread depth
Deep threads are sometimes completely unnecessary. It is usually best to design the depth of threads to be from 1.5 X to 3 X the diameter of the threaded holes.
Avoid Excessive Tolerance
Take note that excessive tight tolerances will increase machining difficulties & costs. Thus, narrow tolerances requirement should only be indicated as necessary.
holes with standard sizes
Holes with standard size can be CNC machined by standard drill bits with accuracy and high speed. This can help save machining cost in contrast to non-standard size holes.
avoid Excessive aesthetic
Prioritizing the accuracy of necessary features over aesthetics will help improve your design, as cosmetic requirements can be achieved with finishing.
Avoid Thin Wall
It is quite difficult for accurately machining thin-walled parts. To keep machining costs low, the minimum thin wall should be 0.8 mm for metal parts and 1.5 mm for plastic parts.
Avoid too Small Features
Too small features such as less than 2.5 mm in diameter will increase the machining difficulty and machining costs, thus it should be avoided except when necessary.
Right Thread Size
The recommended thread size is M6 or above, avoiding thread sizes smaller than M2, and it is also important to avoid designing holes that cannot be threaded.
Necessary Radii
Unless the sharp inner corner is specified in your design, it will be machined to a 2 mm radii by default.
Sharp inner corners can be machined with EDM if necessary.
Why Choose Us For Machining Service

Surface Finishes For Machining Parts
Bead Blasting
If aesthetic appearance is essential, bead blasting is the finish we prioritize. Parts can be bead blasted from #60 to #200 grit.
Anodizing
Resistant to corrosion and oxidation, anodized parts has a great color, and a uniform, clean, matte or glossy appearance.
Plating
With great looking and corrosion resistance, such as silver, gold, nickel, zinc or chrome plating and electroless nickel plating.
Powder Coating
Compatible with all metals, and allows for a very uniform looking colors with great corrosion and wear resistance.
Painting
It involves spraying a layer of paint onto the surface of the part. The finishes range from matte to gloss.
Polishing
Parts can be polished in multiple directions, and their surface are smooth and slightly reflective.
Black oxide
Applicable on steels, this process is used to improve corrosion resistance and reduces light glare.
