Operation Specifications for Juxin CNC Face Milling and Center Hole Drilling Machine

The operation specifications for the Juxin CNC face milling and center hole drilling machine are as follows:

1. Preparation before operation:

Operators must be familiar with the performance, structure, transmission principle, and control program of the machine tool. Only after obtaining an operation certificate through on - the - job training can they operate the machine.

Before starting the machine, check the handover records and the following items. Power can be turned on only after ensuring everything is in order.

2. Clamping the workpiece:

The part to be processed is clamped on the worktable. During the cutting feed process, the face mills at both ends of the part can ensure its fixed length.

For shaft - type parts such as crankshafts, the center holes of the lathe are usually used for positioning. For the center holes on the surface of the carriage, since there is only one processing tool, it must be turned around during the processing, and two fixtures are used to complete the processing of the center holes at both ends of the shaft.

3. Adjustment and tool setting:

Adjust the positions of the milling power heads on both sides to ensure that the distance between the tips of the face mills on both sides is equal to the fixed length of the part to be processed.

The milling cutter is set using two right - angled tool - setting blocks.

4. Processing process:

Adopt a horizontal CNC servo - drive method. The power heads at both ends simultaneously complete the milling of the two ends of the workpiece, and at the same time, complete the drilling of the center holes at both ends or the turning of the outer circles at both ends.

During processing, first position with the outer circle surfaces of the two main shafts of the blank, mill the end faces first, then process the center holes. After that, position with the center holes at both ends, and then rough - and finish - machine the surfaces, threads, keyways, and crank end faces of each shaft. Finally, rough - and finish - grind each journal.

5. Daily maintenance and upkeep:

Formulate and strictly implement the daily maintenance regulations of the CNC system. Regularly inspect and replace worn parts according to different maintenance requirements to keep the machine clean and well - lubricated.

6. Safety precautions:

During the operation, strictly follow the operating procedures to avoid overloading and misoperation.

Ensure that all protective devices are in good condition and effective to prevent accidents.

By following the above steps and precautions, the safe and efficient operation of the Juxin CNC face milling and center hole drilling machine can be ensured.
