Main job is to guarantee the scraping interaction and equipment on both sides of the friction surface or can obtain higher precision and accuracy, precision and shape accuracy, precision and contact transmission because of good lubrication, manual and repeatedly is worthy, large amounts of wind, time-consuming, scraping the time needed for different devices vary, such as boring slider and slide block wind profiling, between the match before measuring clearance between the original value, and then according to the technical requirement to measure the value of time and scraping scraping, then apply DanFen red on the slider, manual let slip on the slide seat back and forth, they do straight-line movement between full contact and friction, reoccupy scraper scraping friction creates the contact point, so repeatedly, until the technical requirements for the match, single within 2 days, must blow to the boring if all the time to work with wind, a half month is required.

刮削过程。刮削工作主要是为了保证设备相互接触并摩擦的两面间能获得较高的尺寸精度、形状精度、位置精度、接触精度、传动精度和良好的润滑，因是手工操作且需反复配刮，故工作量大，耗时较长，设备不同，刮削所需时间也各不相同，例如镗床上滑座与下滑座间的配刮，刮削前先测量出二者之间原有的间隙值，然后根据工艺要求测算出需刮削值及每次的刮削量，再将红丹粉涂于上滑座之上，手工让上滑座在下滑座上来回做直线运动，使它们之间充分接触和摩擦，再用刮刀刮削摩擦产生出的接触点，如此反复多次，直至技术要求范围之内，单此项配刮需2天左右，若对于整个镗床所有配刮工作的时间总和，则需半个月左右。

This kind of energy release — known as triboluminescence and seen in the form of light — occurs whenever a solid is crushed, rubbed or scratched.

这种能量释放——被认为是摩擦发光而且是光的一种组成形式——通常发生在固体发生了碰撞、挤压或者摩擦的时候。
