(xvii), there is an abnormal sound, you should stop immediately to check; maintenance or replacement parts before you must cut off the power supply, and wait for the saw blade completely stopped.
(xviii), the use of cutting machines such as working in wet places, must stand on insulating mats or dry boards. Climbing or in explosion-proof and other hazardous areas must be used to do a good job of safety measures.
(xix), equipment shaking and other malfunctions, should be immediately shut down for repairs, it is strictly prohibited to take sick and take stimulants and alcohol work, operation is strictly prohibited to wear gloves operation. If the operation process will cause dust, to wear a mask or mask.
(xx) Processing should be turned off, and do a good job of cleaning the equipment and the surrounding area. 1, the operation is completed should be tap water to rinse the studio and workbench surface of the rock slag and dry.
2, regularly clean up the oil stains on the drag plate and guide rail and guide rail drive screw, and timely filling of lubricating oil.
3, after all the work is finished, move the blade forward about 10 centimeters to reset the travel switch rocker.
4, cutting machine after the use of the whole machine such as in a certain period of time is not used, should be the blade and fixture moving parts and some easy to rust inside the machine coated with a layer of lithium
I. Daily maintenance and repair:
1. Every working day must clean the machine tool and the guideway of the dirt, so that the bed to keep clean, off work off the gas and power supply, while emptying the machine tool pipe belt in the residual gas.
2. If you leave the machine for a long time, turn off the power to prevent non-professional operation.
3. Observe the machine horizontal and vertical guide and rack surface with or without lubricant, keep it well lubricated! III. Weekly maintenance and maintenance:
1. Every week, we should carry out a comprehensive cleaning of the machine, horizontal and longitudinal guide rails, transmission gear rack cleaning, adding lubricant.
2. Check whether the transverse and longitudinal rail wipers work properly, such as abnormal timely replacement.
3. Check whether all the cutting torches are loose, clean the garbage in the ignition muzzle to keep the ignition normal.
4. If there is an automatic height adjustment device, test whether it is sensitive, whether to replace the probe.
5. Check whether the plasma cutting nozzle and electrode damage, whether to replace the cutting nozzle and electrode.
II. Monthly and quarterly maintenance:
1. Check the total air inlet for garbage, each valve and pressure gauge is working properly.
2. Check all air fittings for looseness and all hose bands for breakage. Tighten or replace if necessary.
3. Check all transmission parts for looseness, check the meshing of gears and racks, and make adjustments if necessary.
4. Loosen the tightening device, push the carriage by hand, whether it is free to come and go, if there are abnormalities in time to adjust or replace.
5. Check the clamping block, steel belt and guide wheel for loosening, steel belt tightening, adjust if necessary.
6. Check the performance of all buttons and selector switches, damaged replacement, and finally draw a comprehensive test graphic to check the accuracy of the machine.
Base butter. 1, cutting machine installation is completed, turn on the power to check the machine parts of the rotation is flexible, whether the fasteners are loose.
2, turn on the power, press the host button, whether the blade steering in the same direction as the arrow. If reverse immediately adjust. After checking, you can clamp the rock samples for cutting, rock samples clamping, you should choose a reliable clamping point to prevent false clamping and false clamping phenomenon. In order to avoid damage to the tool and rock samples due to rock scrambling during the cutting process.
3, clamping irregular rock, available top pressure method of clamping, clamping method shown in Book 1. Clamping steps: first of all, the rock sample 8 flat on the table, and then the top pressure moving fixture 10 along the T-slot 3 inserted, selected fixture and the distance between the rock sample, locking fixture base screws, up and down to move the top bolt 13, in order to select a reliable clamping point, and then the top moving nut 11 lock, and then rotate the top rod until the top rod of the rock sample to the top of the dead, and at the same time to tighten the top rod nut 12, to prevent the top rod in the cutting process. to prevent the top bar from loosening during the cutting process.
4, cutting core samples, such as the number of rocks is more, can be randomly attached to the long platen pressure on several pieces of rock samples, together with the cutting, in order to improve the efficiency of work, the clamping method as shown in Figure 2, the steps are as follows: the rock samples 8 flat on the table 6, the platen bolts along the T-slot 3 inserted into the long platen 9 end inserted into the vertical surface of the table in the square holes, rotate the adjusting screws and the platen bolts nuts 10, the rock sample can be pressed, such as the core sample diameter size of a slight error, you can add a shape of a thin wooden board on top of the rock sample, so that the long pressure plate can be pressed to the rock sample. Clamping cut off the shape of the rectangular and square rock samples, also apply this method.
5, work, the first start the main motor, and then press the work into the button, start cutting, because the rock is more irregular shape, this time into the knife speed should be slow, to be the blade edge all into the rock samples, can be a little faster.
6, the cutter automatically in and out of the knife, when the cutter along the table movement to the end, can automatically back to the beginning, and automatically stop moving. If you need to go back in the working process, press the console fast-return button. If you need to move forward in the fast retreat, press the work in button to enter the knife as well. Whether the knife or backward, press the stop button cutter can stop moving. When working, if you find that the cutter is far away from the rock sample, you can press the fast forward button (press and hold) or tap fast forward, when the blade is close to the rock sample, that is, release the button. Then press the work-in button again for normal cutting. This can shorten the feed assist time. The machine feed drive is shown in Figure III.
7, in cutting the specimen, before the work can be based on the rock hardness to adjust the feed speed, in the cutting process to adjust the feed speed may appear knife marks, according to the use of experience in cutting the harder stone, the speed is generally about 40 mm / min.
