We will follow strictly the tolerance requirements specified on the drawings, and for unspecified tolerances, ISO 2768 -m or ISO 2768 -f 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 Tips 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 and machining costs. Thus, narrow tolerances requirement should only be specified 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 aesthetic requirements can be achieved with finishing such as polishing.
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, 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
In order to avoid wear and tear of tool, it is necessary to add radii to inner edges (round the internal corners) in your design to avoid unnecessary pressure on the tool.

Surface Finishing
Bead Blasting
If aesthetic appearance is essential, bead blasting is the finish we prioritize. Parts can be bead blasted from #60 to #150 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 etc.
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 are polished in multiple directions. The surface of the polished parts are smooth and slightly reflective.
Black oxide
Applicable on steels, this process is used to improve corrosion resistance and reduces light glare.
Part Marking
When it comes to part marking, the parts can be marked with logos, custom lettering or a whole image.

Applications for CNC Machining
CNC machined parts have a very wide range of applications, from consumer goods to aerospace. Due to its high precision and flexible machining methods, CNC machining process is particularly suitable for small batches or prototypes of complex parts. In addition, precision CNC machining is also often applied to post processing for die casting, forging and injection molding.
Automotive

Aerospace
Most parts used in the aviation industry generally have rigorous requirements, both in terms of materials and tolerances, such as adjusting screws, pins, impellers, titanium fasteners, stems and shafts.
telecommunications
Our CNC machining service are also used for microwave towers, heat sinks, RFI shielding, amplifier housings and other enclosures, many of these parts require good surface finishing and machining.
Medical Devices
The parts involved in medical devices are also in our manufacturing range. Such as bone screw, stabilizer, fixation piece, valve stems, valve seats, valve bodies, nipples, miniature motor shaft, etc.
Machinery & Equipment
Our custom parts are also applied to glove dipping lines and heavy machinery & equipment, inclusive of the related parts for conveyor chains & former holder sets and undercarriage components.
