What should we pay attention to when checking the cutting tools of surface grinder

The small partners working in the factory must know that it is necessary to check the machine at work or after work. Only the normal operation of the machine can ensure the normal production in the factory, and so is the surface grinder. In normal operation, it is often necessary to reflect on the length of the cutting tools of the surface grinder! Let's briefly understand what aspects should be paid attention to in the reflection on the cutting tools of the surface grinder in the ordinary production process!

Before the work of surface grinder, check whether the scattered cutting tools are safe and easy to use, whether the position of each hand wheel rocker is wrong, whether there is friction obstacle in fast feeding, and whether each limit switch can play the role of insurance protection.

When assembling cutter bar, support, washer, indexing head, vice, cutter hole, etc., the parallel surfaces shall be wiped clean, and the milling machine shall be kept free of dirt. Before the cutting tool is used, check whether the cutting tool can be firmly installed and whether the work piece can be firm. The sizing block supporting the pressing plate should not be too high or the number of blocks is too large. The cutter rod gasket should not be used for other pads. Check the parallelism before application. When inheriting high and low work, fastening, adjustment, speed change and measuring work on the surface grinder tool, be sure to park. When replacing the cutter rod, cutter head, end milling head and milling cutter, stop the machine first. After the power switch is turned off and the pull rod screw is loose, be careful to avoid the damage of the staff hanging flowers or knives.

When the tool is running, it is forbidden to measure the size, align the template or touch the machined surface by hand. When taking and unloading the workpiece, it is inherited after moving the tool. When starting each moving part every time, pay attention to whether the tool and each handle can be in the position of the homework range. When pulling the handle quickly, you should first open it gently to see whether the moving part and position are consistent. It is forbidden to drive suddenly and move the handle quickly.

When assembling and disassembling the end milling cutter, the table must be padded with stone plate, and it is forbidden to support the cutter head by hand. When installing a flat milling cutter and using a wrench to pull the screw nut, pay attention to the proper selection of the wrench. The force should not be too strong to prevent slipping.

When setting the knife, be sure to feed the knife slowly. When the knife is close to work, it is necessary to manually feed the knife. Fast feeding is prohibited. When walking the knife, parking is prohibited. Park and retract the tool when milling deep groove. Pay attention to the injury caused by the handle when fast feeding. When milling vertical feed, the workpiece loading card shall be at a certain distance from the worktable.

The surface grinder shall not be too hard to eat the knife. The hand wheel on the worktable must be used to walk the knife. It is forbidden to change the feeding progress suddenly. The infinite bump should be adjusted later. When the homework is finished, turn off the switches, pull the handles of the cutting tools back to the open space, wipe the cutting tools and inject greasy oil.
