Introduction to milling machine operation

Today to share with you milling machine operation entry 16 operating rules, see you understand it

 

1.The operator must be familiar with the machine structure, performance, operating system, transmission system, protective device, lubrication parts, electrical and other basic knowledge, use method.

 

2. Before the operation of the machine according to the provisions of wearing labor protection equipment, female workers must put their hair into the working cap, wear protective glasses when high-speed cutting, wear masks when processing castings. Do not wear gloves, scarves and aprons to operate.

 

3.Before starting, check the handle position, the transmission parts and protective cover, limit device, cutter head is firm and reliable, cutting fluid meets the requirements, electrical protection zero reliable, etc. CNC milling machine should also check the program, parameter setting and so on. After inspection, pre-shift lubrication and refueling shall be carried out according to the parts and oil quantity specified in the lubrication chart of the machine tool. The guide rail is strictly forbidden to be oiled when casting is processed.

 

4. After checking and refueling, the operator drives at low speed idling for 3~5 minutes to check whether there is any abnormal sound in the operation of the machine tool, lubrication of various parts, lubricating oil level, whether the control handle is flexible, whether the chain mechanism is normal and reliable, whether the handle and handwheel tooth embedded clutch is normal. CNC milling machine should also be processed according to the process of empty running inspection.

 

5. Concentrate during processing and operation, and it is strictly forbidden to talk with others. It is strictly forbidden to leave the post when automatically moving the knife; No driving speed change; Not allowed to exceed the standard use; Do not remove the mechanical limit at will; Do not place articles on the guide rail; No private installation of redundant devices; It is not allowed to operate with rope or wire bolt handle. Stop the machine when leaving the machine and turn off the power for a long time.

 

6.Clamping milling cutter, work surface should pad wood. Check the tool taper handle should be correct taper, clean without burr, clamping force should be uniform, clamping firm and reliable, and check whether it is loose at any time. 

 

7. When clamping the workpiece, the workpiece must be secure and reliable.

 

8. When working, the operator must stand on the side of the milling cutter cutting direction to prevent the cutting tool, workpiece and chip from crashing and wounding. When the chip splashes, the machine should be set around the chip plate.

 

9. longmen milling clamping large parts, the crane should be operated correctly, the workpiece hanging firm, clear command, carefully check whether there are obstacles on the workbench, the mold is firmly installed, positioning datum is clean, do not support the bottom of the workpiece by hand, the use of slow speed when falling, is not allowed to impact the machine. After the positioning is correct, tighten the bolt pressure plate and check that there are no obstacles on each sliding surface before processing. After processing, it is necessary to loosen the bolt pressure plate and ensure that there is no lifting obstacle before lifting down the workpiece. 10. When measuring the workpiece, it is necessary to stop the workpiece and retract it away from the tool before measuring the workpiece.

 

11.Processing is strictly prohibited by hand to clean up chips, must use special tools. When processing chip accumulation is too much, should stop in time to clean up. Do not use compressed air to clean chips.

 

12.Cutting liquid cooling flow should be adjusted appropriately, cooling parts should be reasonable, not allowed to produce splash during processing. Metamorphic cutting fluid should be cleaned and collected in time, and sent to the designated collection place of the unit. Dumping is strictly prohibited.

 

13.Gantry milling working lamp voltage must be below 36 volts, wiring does not affect the operation of the machine tool, tidy when not in use, placed in a fixed place.

 

14.Machine failure or abnormal sound, should be stopped in time to check and deal with. If it cannot be handled, report to maintenance personnel for treatment in time, and fill in daily maintenance records and downtime records after treatment. All electrical faults are strictly prohibited to be handled by the operator. 15, at the end of processing or work, should be according to the end of the class equipment maintenance requirements, clean up chips, clean up felt mat, thoroughly wipe the equipment, guide rail, workbench and exposed parts of the precision oiling maintenance.

 

16.Maintenance content: thoroughly clean up the cutting dirt; Thoroughly wipe the equipment; Clean oil filter, felt pad, oil wool; Check the quality of lubricating oil and impurities precipitation; Check coolant status. Clean the flat pliers once a month.
