Measurement system of Roll Grinder
At present, roll measurement methods in China and at abroad are generally divided into two categories. Firstly, due to the emergence of online roll grinding (ORG) technology for steel rolling, which produces online roll shape measurement technology; the second category is roll grinding and roll production. Roll measurement technology. There are also some measuring equipment such as snap gauges and saddle gauges that are low-cost and low-precision. Among them, the roll measuring of CNC roll grinding machine has the highest measurement accuracy. However, according to the analysis of CNC software for CNC roll grinder's measurement systems at home and abroad, there are not many functions that can truly measure the roll installation taper, roll shape and roundness, and the machine tool guide rail and roll shape compensation functions of the roll grinder are not enough. It's even more blank. The functions that can be realized by the measurement system CNC software are as follows:
(1) Automatic and manual measurement of rolls.
(2) Calibration function of the roll measurement device before roll measurement.
(3) Correction and compensation of guide rail calibration data of roll grinder.
(4) Taper measurement and compensation of roll installation.
(5) Straightness measurement function (when measuring the roll curve, analyze the direction and roll compensation).
(6) When measuring the roll shape, the theoretical curve, roll measurement trend curve, and error separation curve can be displayed simultaneously, and the measurement graphic interface is designed into two display windows to facilitate error display and analysis; the roll shape is realized The error is separated from the guide rail error and the measurement frame movement error, and the compensation data of the roll processing is obtained.
(7) Measurement of roll concentricity.
(8) The measurement and evaluation of roll roundness is carried out using the four methods specified by national standards. The roundness error curve obtained in the interface is the true roll roundness error curve after the spindle motion error is separated.
