Thread processing machine operation steps

Applicable models:

1. Thread milling machine: S6110, SB6110, Y620 (563B), J620, Y68 (5M5Б62), J68, S6125, 5Б62, 561.

2. Thread machine tool: KT38A, SB8918, CFI. Conscientiously implement the following relevant regulations.

1. The operator must pass the examination and hold the 'Equipment Operation Certificate' of this machine tool to operate this machine tool.

2. Earnestly do it before work:

1. Read the shift record carefully to understand the operation status and existing problems of the machine tool in the previous shift.

2. Check the machine tool, workbench, guide rail and all main sliding surfaces. If there are obstacles, tools, iron filings, impurities, etc., they must be cleaned, wiped clean, and oiled.

3. Check the workbench, guide rails and main sliding surfaces for new pulling, grinding, or bruising. If there are any, notify the team leader or equipment personnel to check together and make a record.

4. Check the safety protection, braking (stop), limit and reversing devices should be complete and intact.

5. Check that the mechanical, hydraulic, pneumatic and other operating handles, gates, switches, etc. should be in non-working positions.

6. Check that each tool post should be in a non-working position. (Guide: Five maintenance methods for hardware accessories)

7. Check that the electrical distribution box should be closed firmly and the electrical grounding is good.

8. Check that the amount of oil in the oil storage part of the lubrication system should meet the requirements and be well sealed. The oil indicator, oil window, oil cup, oil nozzle, oil line, oil felt, oil pipe and oil separator should be complete and installed correctly. According to the lubrication instruction chart, do manual oiling or motorized (hand position) pump oiling, and check whether oil is coming from the oil window.

9. For machine tools that are parked for more than one shift, they should be run dry for 3 to 5 minutes in accordance with the regulations in the manual and the prescribed start-up procedures and requirements for the use of the hydrostatic device. an examination:

①Whether the control handles, gates, switches, etc. are flexible, accurate and reliable.

②Whether the safety protection, brake (stop), interlock, clamping mechanism and other devices are working.

③Check whether the movement of the mechanism has enough stroke, adjust and fix the limit, fixed-stroke stopper and reversing bumper, etc.

④Whether there is oil in the lubricated parts of the motor pump or the hand pump, and whether the lubrication is good.

⑤ Whether the motion, working cycle, temperature rise, sound, etc. of the mechanical, hydraulic, static pressure, pneumatic, profiling, profiling and other devices are normal. Whether the pressure (hydraulic pressure, pneumatic pressure) meets the requirements. After confirming that everything is normal, you can start working.

Any equipment that is continuously transferred, the transferee shall inspect the equipment in accordance with the above (Article 9) together, and the transferee can leave only after the transfer is clear. For equipment that is succeeded from another shift, if a serious violation of the operating procedures is found in the previous shift, the team leader or equipment personnel must be notified to check it together and make a record, otherwise it will be dealt with according to the violation of the operating procedures of the shift.

After the equipment is overhauled or adjusted, the equipment must also be inspected in detail according to the above (Article 9), and it can be started only after it is deemed that everything is correct.

Three, earnestly in the work:

1. Stick to the post, operate meticulously, and don't do anything unrelated to the job. Stop the machine when leaving the machine due to accidents, and turn off the power and air supply.

2. Process according to the process regulations. It is not allowed to arbitrarily increase the amount of feed, the amount of grinding and the cutting (grinding) speed. It is not allowed to use the machine tool beyond the specification, overload and weight. Rough use of precision machines and small use of large machines are not allowed.

3. The tool and workpiece should be clamped correctly and fastened firmly. Do not damage the machine during loading and unloading. Align the tool, and the workpiece is not allowed to be hit with a heavy hammer. It is forbidden to tighten the tool and workpiece by lengthening the handle to increase the torque.

4. It is not allowed to install thimble, cutter, knife sleeve, etc. in the taper hole of the machine tool spindle, the taper hole of the tailstock sleeve and other tool installation holes, the taper or the diameter of the hole does not match, the surface has nicks and is not clean.

5. The mechanical speed change of the transmission and feed mechanism, the clamping and adjustment of the tool and the workpiece, and the manual measurement of the workpiece between the working procedures should be stopped after the cutting and grinding are terminated, and the tools and abrasive tools should be moved away from the workpiece. get on.

6. Knives and abrasive tools should be kept sharp, if they become dull or cracked, they should be sharpened or replaced in time.

7. During cutting and grinding, the tool and abrasive tool are not allowed to stop if they do not leave the workpiece.

8. It is not allowed to disassemble the safety protection device on the machine tool without authorization, and the machine tool lacking the safety protection device is not allowed to work.

9. The hydraulic system is not allowed to adjust without permission except for the throttle cutting.

10. Tools, workpieces and other sundries are not allowed to be placed directly on the machine tool, especially on the guide rail surface and work table surface.

11. Frequently remove iron filings and oil stains on the machine tool, and keep the guideway surface, sliding surface, rotating surface, positioning reference surface and working table surface clean.

12. Pay close attention to the operation and lubrication of the machine tool. If abnormal phenomena such as malfunction, vibration, heat, crawling, noise, peculiar smell, bruising, etc. are found, stop and check immediately, and then continue to work after troubleshooting.

13. In the event of a machine tool accident, you should immediately press the master stop button, keep the accident site, and report to the relevant department for analysis and processing.

14. Welding and repair welding of workpieces on the machine are not allowed.

Four, earnestly after work:

1. Put the mechanical, hydraulic, pneumatic and other operating handles, gates, switches, etc., to the non-working position.

2. Stop the operation of the machine tool and cut off the power and air supply.

3. Remove iron filings, clean the work site, and carefully clean the machine tool. Refuel and maintain the guide rail surface, rotating and sliding surface, positioning reference surface, and working table surface.

4. Carefully fill in the machine tool problems found in the shift in the shift record book, and do a good job of shifting.
