What are the precautions when ?????????? Precision Machining stretch it? Precision drawing parts manufacturers here to answer them, I hope you can use to help you in the future can be used. 1. Do not open with staff cuffs, wear tight protective clothing, long hair to wear helmets, not wearing gloves, chuck operation, there must be secure faceplate bolts to be tightened before use; cone axis chuck to be installed on the lever. 2, in addition to the lathe is equipped with work outside the active measurement equipment, parking should be measuring the workpiece and tool holder moves to the safety position. When turning slender workpieces should be used to guarantee the safety of the intermediate frame or with the knife, partially due to grow lathe marks. 3, lathe work before the job shall examine the situation, identify problems and timely disposal, clamping the workpiece and the tool to be tightened. Workpiece clamping chuck, dial, protruding part of the best heart-shaped clip using shields, avoid clothes and live in other parts of the cutter body. Materials drawing parts: General requirements for stretching the material has good ductility, low yield ratio, the large thickness of directivity and a small plate plane direction. The stretch material mold parts have been identified as 08 steel. Stretching pieces of tolerance: the dimensional accuracy of the tensile member should T13 level below, not above the IT11 level. This drawing parts look-up table to determine the level of accuracy for IT12 ~ IT13., Drawing a blank thickness t = 0.5mm. Stretch wall thickness tolerances should generally not exceed the thickness variation of the drawing process. Stretching pieces of dimensions, should be marked to ensure the dimensions, or the internal dimension, can not be marked within the dimensions. Stepped drawing parts, the size of the height direction should generally be marked at the bottom of the base, if the upper portion of the base, the height is not easy to guarantee. Precision drawing parts manufacturer Kechuang stretching pieces work well, reasonable price, like friends, please come quickly to contact us.
