2, every time you drive and start the moving parts, pay attention to whether the tool and the handle are in the required position. When you move the handle quickly, you must start it gently first to see if the moving part and direction are consistent. Do not start the fast moving handle suddenly.
3, installation tool rod, bracket, washer, dividing head, vise, knife hole, etc., the contact surface should be wiped clean.
4, before the machine starts, check whether the tool is installed, whether the workpiece is firm, the pressure plate must be stable, the cushion iron supporting the pressure plate should not be too high or too many blocks, the tool bar washer can not be used for other pads, and the parallelism should be checked before use.
5, in the machine tool for up and down the workpiece, tool, fastening, adjustment, speed change and measurement of the workpiece must be stopped, replace the tool rod, cutter, end milling head, milling cutter, should be stopped.
6, when the machine starts, do not measure the size, the template or touch the processing surface by hand. Do not put the head close to the machining surface to observe the cutting situation during processing. When removing and unloading the workpiece, the tool must be moved before proceeding.
7. When disassembling the end mill, the table must be padded with wood, and it is forbidden to use the hand to support the cutter.
8, install the flat milling cutter, when using the wrench wrench nut, pay attention to the appropriate choice of wrench opening, the force can not be too strong, to prevent slipping.
9, the knife must be slow feed, the knife close to the workpiece, need to hand feed, not fast feed, is walking the knife, no stopping. Stop and withdraw the tool when milling deep groove. When feeding quickly, pay attention to hurting people by the handle. When the universal milling vertical feed, the workpiece clamping should have a certain distance from the workbench.
10, the knife can not be too strong, automatic knife must pull off the handwheel on the workbench. Do not change feed speed suddenly.
11, in the process of milling must clear the gap between the lead screw and the nut, to prevent damage to the milling cutter.
12, open fast, must make the hand wheel and shaft off, to prevent the hand wheel rotation hurt, high-speed milling, to prevent iron filings hurt, and not brakes, to prevent the shaft cut off.
13, the vertical, horizontal and vertical movement of the milling machine should be consistent with the direction of the operating handle, otherwise it can not work. When the milling machine is working, the longitudinal, horizontal and vertical automatic cutting tool can only choose one direction, and the safety baffle in each direction can not be removed at will.
14, at the end of the work, turn off the switch, pull the handle of the machine tool back to the vacant position, wipe the machine tool, fill lubricating oil, maintain the machine tool clean.
