Introduction spindle component is an integral part of the lathe. It directly affects the vibration of workpiece surface quality and tool life and so on. Thus the spindle vibration components of its performance, it is very important. This paper on the impact of the headstock to make some of its temperature discussed. Second, the testing program 1. headstock spindle membership temperature measurement Measurement of temperature field measuring points and the measuring device shown in Figure 1, in which a measuring point near the front bearing at the spindle, spindle measuring point near the middle bearing location 2, measuring point 3 near the Spindle bearings at the measuring points thatch near the clutch position (the other side of the box) . thermocouples 0.28tara made of copper wire of a health and glue in the box with the 5O2 measured wall temperature measurement box circles around a BC1 eleven standard battery UJ31 - dc cover meter Ac15/5- - the starting point for the optical galvanometer X0Y0, perform the following procedures are shown in Figure 4 the trajectory.

Each compensation point of the composition by the two parameters, even parameters of the coordinate value for the compensation point (relative to machine zero), the odd parameters of the compensation point of the error (relative to the machine reference point .) compensation for use of the pitch should note the following points; 1. machine reference point must be as a compensation point, and this error is zero, meaning that the measurement error must be '2 machine as the base reference point. If you need to compensate point less than 30 have used high-Jing investment parameters should be set to zero} 3. the compensation point of the coordinates of the location must be less than ± 8388.607mm ~ 4. The distance between two adjacent points must be less than 524. 278mm; 5. error must be less than ± 32.766mm ~ 6. two adjacent points of difference between the error must be less than ± 0.128ram. a 3l a
