Automatic CNC Machine Precautions? CNC machine tool is a high degree of automation, complex structure of advanced processing equipment, in order to fully deliver the advantages of machine tools, improve production efficiency, manage, use, repair CNC machine tools, the quality of technical personnel and civilized production is particularly important. Titanium Hao machinery is based on rotary center, lead screw, shaft processing, Automatic CNC Machine processing, the operator in addition to familiar with the performance of CNC machine tools, skilled operation, but also must develop a civilized production of good work habits and rigorous work style, with good professional quality, responsibility and spirit of cooperation.
First, basic precautions for safe operation
1. Please wear work clothes, safety shoes, work cap and protective goggles when working. Note: gloves are not allowed to operate machine tools;
2, be careful not to move or damage the warning sign installed on the machine tool;
3, be careful not to place obstacles around the machine, the working space should be large enough;
4, if a job needs two or more people to complete together, should pay attention to the coordination between each other;
2. Preparation before work
l, the machine work to preheat before the start of work, carefully check whether the lubrication system is normal, such as the machine tool for a long time has not started, you can first use manual way to supply oil to each part of the lubrication;
2, the tool used should be in line with the specifications allowed by the machine tool, and the tool with serious damage should be replaced in time;
3, adjust the tool used in the tool do not forget in the machine;
4. Whether the center hole of large-size shaft parts is suitable, if the center hole is too small, it is prone to danger in the work;
5, the tool should be installed after a second or second test cutting.
6, check the status of chuck clamping;
Third, safety precautions in the process of work
l, do not touch the knife tip and iron filings with your hands, iron filings must be cleaned with iron hooks or brush;
2. Do not touch the rotating spindle, workpiece or other moving parts by hand or in any other way;
3. It is forbidden to measure and change speed during processing, and it is not possible to wipe the workpiece with cotton silk or clean the machine tool;
4. During the operation of the lathe, the operator shall not leave the post, and the machine tool shall stop immediately when it finds abnormal phenomenon;
5, often check the bearing temperature, too high should find the relevant personnel to check;
6, in the process of processing, is not allowed to open the machine protection door;
7. Strictly abide by the post responsibility system, the machine tool is used by special person, and the use of others must be approved by me;
8, when the workpiece extends out of the lathe 100mm, the protective object must be set up in the protruding position.
9. No tentative operation is allowed.
10, manual origin regression, pay attention to the position of the machine tool axis to be more than 100mm from the origin, the machine tool origin regression sequence is: first +X axis, followed by +Z axis.
11, the use of hand wheel or rapid movement to move the position of each axis, be sure to see the machine X, Z axis in each direction of the "+, -" sign before moving. When moving, first slowly turn the hand wheel to observe the moving direction of the machine tool and then speed up the moving speed.
12, after completing the program or entering the program into the machine tool, it is necessary to carry out graphic simulation first, and then carry out the machine test run after accuracy, and the tool should leave the workpiece end face more than 200 mm.
13. Precautions for program operation:
(1) The tool should be accurate, and the tool compensation number should be consistent with the program call tool number.
(2) Check whether the position of the function keys of the machine tool is correct.
(3) The cursor should be placed in the main program header.
(4) Insert appropriate amount of coolant.
14, carefully observe the cutting and cooling conditions during the processing to ensure the normal operation of the machine tool and the quality of the workpiece.
15, in the program operation must be suspended to measure the size of the workpiece, to be completely stopped until the machine, the spindle can be measured to avoid personal accidents.
16, shut down, to wait for the spindle to stop for 3 minutes before you can shut down.
17, do not open the electrical box without permission.
18. Each manual lubrication point must be lubricated according to the instructions.
19, the key to modify the program should be removed immediately after the program adjustment, not inserted in the machine tool, so as not to inadvertently change the program.
20, the use of machine tools, must use the oil cutting cycle 0.5 hours a day, the winter time can be slightly shorter, the cutting fluid to be replaced regularly, generally between 1-2 months.
