We adopt international standards ISO 2768 To control uninjected linear tolerances of machined parts，Among them ISO 2768(F) applies to metal parts，ISO 2768 (M) is suitable for plastic parts。Normally，We can guarantee processing accuracy of ± 0.10mm to ±0.05mm。If tighter tolerances are required，You will need to provide a 2D drawing with complete annotation information，Our engineering team will communicate critical dimensional tolerances with you，and provide the highest possible processing accuracy。What's important，due to increased scrap rates、Additional fixtures and/or specialized measuring tools，Tighter tolerances may result in additional costs。

same as high features，Vibration increases when machining thin features。as a guide，The minimum thickness of metal thin-walled parts is 0.5-0.8mm，The minimum thickness of plastic parts is 1.0-1.5mm。If the wall is used for supporting or higher features，The wall thickness should be increased，To avoid vibration during processing。
You may need to mark the part with the part number or company name，Adding text looks cool，But processing is very time-consuming，Electrochemical etching or laser engraving is usually better。If you must mill text，Choose sunken rather than raised text whenever possible，Keep it simple with larger text，Font depth does not exceed 0.3mm。
When creating threads，It’s also important to stick to standard sizes。The larger the thread，The easier it is to process。The length should be kept to a maximum of the nominal diameter of the hole 3 times。For blind hole tapping，It is best to add at least at the root of the hole 1/2 Extra length of aperture。You may also consider using inserts，Threaded coils and copper nuts last longer than bare machined threads，Especially in materials like aluminum or plastic，and easy to install。
Any internal cuts will create fillets，It is half the diameter of the tool used。Milling with smaller tools takes a long time，We recommend that the radius should be larger than the machining depth 1/3。The best approach is to eliminate interior corners or allow the largest possible interior corner radius in the mating part design，and use the same radius on all inner edges，so that the same tool can be used throughout the process。
The depth of the pocket and groove is usually related to the diameter of the tool used to machine the internal fillet.，A good rule of thumb is to keep the pocket depth equal to the tool diameter 3-4 times，Or the groove depth is smaller than the feature width 4 times。Whether blind hole or through hole，Recommended maximum depth is diameter 4 times，The minimum aperture is 1 mm，And it is recommended to design standard size holes。Use a standard drill bit，Can process holes quickly and with high precision；For non-standard holes，Using end mills increases costs。

For CNC machining，Tolerances on all part dimensions will follow the ISO 2768-1 standard。if needed，You can specify tighter tolerances in part specs，This will require 2D technical drawings。Normally，We can control the tolerance range from ±0.125mm to ±0.05mm。
Tighter tolerances exceeding ±0.05mm will be reviewed by our engineers。please understand，Tolerances are greatly affected by part geometry and material type，Our project managers will consult with you on every part，And provide the highest processing accuracy within the allowable range as much as possible。
Importantly tighter tolerances may result in increased scrap rates、Additional costs due to additional fixtures and special measurement processes。The best way to apply tolerances is to apply tight tolerances only in critical areas，This will help keep costs to a minimum。
Once the processing is complete，CNC parts will have slight visible tool marks on the surface，call it”machined surface”。Machined surface roughness (Ra) The standard is 1.6-3.2μm，Surface finish requirements can be increased to 0.8-1.6μm，Or higher 0.2-0.8μm，However, this will require more operating time and higher costs。
