    Quality testing instrument CNC lathe first look at high precision cylindrical surface engraved lines, higher general machine the workpiece surface accuracy reticle inspection should grasp the following points: Before testing, with fine grinding stone to remove burrs engraved lines. Visual inspection reticle sharpness, thickness uniform, whether straightness and length of the distribution reticle meets design requirements. Test starting position size, spacing and length sampling reticle size, measurement methods and preflight same. Carefully check aliquot of engraved lines, namely the pitch fluctuation size. Inspection Points conical surface scribing, scribing conical surface is relatively high, if the engraved line machine machining position adjustment deviation, will not only cause the machine engraved trough deflection, caused by off-center but also because there are engraved groove depth and other ills. In addition to regular projects test score line, it should also have the following points in mind when tests.
    Careful visual inspection with a magnifying glass engraved meter CNC lathe groove depth is consistent. Inspection is located conical surface trough carved prime line position, high dimensional inspection can use cursors and indexing head. When the inspection work clamping plate is placed on a standard high-precision indexing head spindle and standard plate dividing head is parallel to the height vernier caliper engraved thread accurately located spindle center height, this time with a vernier caliper crossed height on the first test of the workpiece 180 degrees corresponding to the positions of engraved lines engraved lines can be detected conical surface is in prime position line conical surface.
Plane inspection points to the heart of the reticle inspection tools to the heart when the score line to line, with a vernier caliper set aside three equal height to score the extension line, if the intersection of the lines coincide at one point to be accurate, otherwise described line to the deviation, and the intersection farther apart, the greater the deviation.
    The above describes meter CNC lathe processing quality scribing how to test, the number of Taian Hai Machinery Manufacturing Co., Ltd. Main CNC lathes, turning centers, machining centers and other welcome new and old customers to order.
