In the prototype fabrication, the customer is bit concerned about the tolerance of the product.Many customers will ask how much precision can be controlled? This is because the higher the precision of the prototype is, the smaller the gap with the actual product will be, and the more real the test result will be, which is also conducive to mold opening and mass production.

     No matter how high the precision of the prototype is, it still has a certain gap with the real object.In the prototype fabrication, there will be no problem in prototype making. if the tolerance can be controlled at ±0.1mm, The precision of the equipment used in the duochuang prototype can reach 0.05mm, and the smaller the device is, the higher the precision will be.

Several factors that affecting tolerance:

    1.CNC cutter: The cutter used in the prototype fabrication machine is generally tungsten steel cutter, the knife will be worn, so there are errors in the knife after several times of use.

    2.Manual correcting of cutter: In order to save the cost that choose the machine without tool, only manual tool in small prototype factory, In order to ensure the precision of the prototype, Duochuang prototype has installed the cutter setting instrument on the CNC equipment, which can not only accurately set the cutter, but also greatly improve the working efficiency.

    3. Machine:The machine itself will also have a certain error, the general error within 0.02mm,and the older the machine, the greater the error.
