They can also cause distortion

CNC machining may be the manufacturing means of choice if you want simple parts with tight tolerances, excellent mechanical properties, and scalable low volume production. To achieve the very best impact from all these strengths, there are many key factors you should consider in the design process.

The keys for learning CNC machine like CNC machining China operation is practice, which could take 1-2 years. You need to master systematic operation method, fitting the fixture, the alignment in the part benchmark, the tool alignment, the setting of zero offset and tool length compensation, the radius compensation, the loading and unloading in the tool and tool handle, the measurement of CNC machining part (including skillfully utilize vernier caliper, the micrometer card, the dial indicator, the dial indicator, the inner diameter lever gauge, etc.). The horizontal machining center can present the operation level. In addition, the fixture design and modification can also be much essential requirement.

Avoid Deep Cavities
The end mill cutting tools have limited cutting length, they typically perform most optimally when cutting cavities having a depth up to 2-3 times their diameter. To minimize cost, we propose limiting the depth from the cavity for the 4X diameter on the tool to guarantee good results. Anything over that will boost the cost, as special tooling or multi-axis CNC systems are important.If larger cavity depth is needed, consider designing parts using a variable cavity depth.

Increase the Thickness of Thin Walls
CNC parts with thin walls are likely to chatter, which holds back machining speeds.They can also cause distortion, so that it is difficult to machine them accurately. The result may be additional machine some time to cost.In order to keep machining costs low, thin walls must have a minimum width of 0.8mm for metal parts, and 1.5 mm for plastic parts.

On which products is your business the highest margins? Often these are typically single pieces and small series. By implementing every one of the previous tips, you would like to automation that may be fully set to the present. With automation you may produce 24/7 and deliver faster because of a shorter product turnaround time. Selling ‘No’ due to low capacity is something on the past. At least until your CNC machine makes 160 hours per week and you have to link another CNC machine towards the automation to meet up with the growing customer demand.

A simple calculation. On average, a CNC machine has 60 tools which 40 are standard. If you produce a lot more than 5 different product series with 5 unique tools per series unmanned, you may already come across problems. A large tool stockroom is unnecessary luxury. Of course this is usually taken into account when using the same tools whenever possible in the CNC programs through the preparation. But what goes on when a miller breaks? Will you lose production and can the CNC machine stand still? Tip 9 supplies a solution.
