However, since these do not directly measure the thickness of the workpiece being machined, an error occurs between the desired size and the actual finished size. Also, since the lapping machine processes many workpieces at the same time, as is generally known, the measured thickness of each finished workpiece shows a normal distribution, and if the workpiece deviates from the desired dimension, Existence cannot be avoided. For this reason, it is necessary to measure the thickness of the finished workpieces one by one and sort them into good products and defective products.

Further, when the sizing device is used, the difference between the desired value and the actual finished size shows different values depending on the machining characteristics of each machine. Therefore, when the work is processed using multiple lapping devices, the thickness of each work is measured for each machine, the measurement result is calculated, and the sizing device is based on the result. It is necessary to correct the setting value input to. However, when the number of operating lapping devices increases, it becomes difficult to manage the work and machining data for each machine, and an accurate value may not be obtained.

Further, the operator must newly input the measurement data of the work after the thickness measurement to the lapping device, which is time-consuming and there is a risk of an input error.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the apparatus of the present invention will be described in detail with reference to FIG. 1. Reference numeral 1 is a lapping apparatus composed of an upper surface plate 2 and a lower surface plate 3, and a work 5 held on a carrier 4 is sandwiched between the two surface plates. , Polish both surface plates and work while rotating.
When the interval between the upper and lower surface plates reaches a predetermined set value, the lapping device 1 is stopped. Then, the work 5 is taken out, the thickness of the work 5 is measured by the measuring device 6, and this is sent to the calculator 7 to calculate the average value, the standard deviation, etc., and the set value is corrected by this, and the next work 5 Start polishing. The printer 8 and the personal computer 9 connected to the arithmetic unit 7 print out and manage the arithmetic data.

Since the work thickness measuring device is provided in each lapping device and is directly connected to the computing device, the worker measures the thickness of the work taken out from the lapping device each time. Only by doing so, the data management of the work for each machine can be surely executed, and the input error of the measurement data is eliminated. Further, by combining with a sizing device, it is possible to perform accurate sizing based on actual measurement data instead of the interval between the upper and lower slabs as in the conventional case. In addition, since a personal computer and printer are connected to the computing unit, it is possible to convert the measured thickness data into the necessary management data and manage the data for each month and lot. Data can be output as needed.
