Four Requirements for Second Hand Roll Grinding
The second-hand roll grinder is an important supporting equipment for sheet rolling production, and its grinding accuracy and grinding efficiency directly affect the rolling quality and production efficiency of the sheet. So, do you know what are the four major requirements for roll grinding? Today, we will give you a detailed introduction.
1. The X-axis feed is divided into grinding stages according to the size of the feed. In order to maintain the rigidity of the oil film of the grinding wheel spindle and the safety of the grinding wheel, the maximum feed is generally between 20-30u m.
2. The main function of the measuring ruler on the grinding wheel frame is to center the rollers and roughly adjust the Towa（supporting blocks). Put the measuring ruler down, then it will be just on the center line of the rotation, after making a rough adjustment of the Towa, fix the measuring ruler, and be sure to fix the screw in place, and make contact with the position sensor, so that the device can better receive the signal.
3. When hoisting the roll, be sure to open the yellow safety door, which can only be closed when the program is running. Four safety devices, mainly yellow safety door, centering ruler, two sensors and anti-collision rubber strip. These four safety devices are all sensitive parts and are safety protection devices. If you touch one of the devices during use, it will cause the program to stop immediately.
4. Once soft landing of roll grinding machine, there should be two green signal lights on the operating platform. However, in actual operation, even if it is a soft landing, there will be a phenomenon that the signal light does not light up, so that the roll cannot be rotated normally and the program cannot be run. A message like this will appear on the alarm that it is necessary to descend to the bottom for soft landing and roll rotation.
The above content is a detailed introduction to the four major requirements of roll grinding, and we hope it will be helpful to you.
