在仪器仪表,特别是钟表的制造和维修中,经常使用精密仪表车床(即台式或案式车床)来车削细小零件。由于车削的零件尺寸很小,因此,所使用的车刀的尺寸相对也很小,而且大多数属于整体切刀。在多数情况下,是用手或者是由带有齿轮和齿条的杠杆或单独的杠杆进给来工作的。这种用在精密仪表车床上的车刀和普通车床上使用的车刀有着明显的不同,特别是在使用和维护方面。 要想使用和维护好仪表车刀,就必须了解影响仪表车刀使用的有关因素,并给予足够的注意,概括地说,这些因素是:车刀材料的类型和性质、刀刃的几何形状、锐度、刀刃的工 In the manufacture and maintenance of instrumentation, particularly clocks and watches, precision gauge lathes (ie, bench or case lathes) are often used to machine small parts. Due to the small size of turning parts, the turning tools used are relatively small in size, and most of them are integral cutters. In most cases, it is operated by hand or by a lever with a gear and a rack or by a separate lever. This kind of tool used in the precision instrument lathe differs from the lathe tool used in the ordinary lathe, especially in terms of use and maintenance. In order to use and maintain the instrument tool, it is necessary to know the factors that affect the use of the instrument tool and pay enough attention to them. Generally speaking, these factors are: the type and nature of the tool material, the geometry of the blade, the sharp Degree, edge workers
