5 minutes to learn operating instructions for milling machine

One, Preparation before operation

1. Turn on the machine's main power, turn on the emergency brake switch of the machine, and finally turn on the motor switch to see if the machine is running normally.

2. Clean the table debris to ensure that there is no debris on the table of the machine.

3. Calibrate the machine head, and make sure the machine table is perpendicular to the machine head.

4. Select reasonable machining fixtures according to the requirements of machining parts.

5. switch on electronic scale, electronic scale work is normal. If you want to high requirement of machining accuracy of workpiece, check with the school table electronic scale reading accuracy and electronic scale return condition. F. shaking the x, y, z axis handle, check machine three axis activity is normal, whether the work of detecting the spindle feed smoothly and reset is normal.

6. If you want to carry out slow machining, check whether the slow shift and operation are normal.

7. Check whether the automatic feeding system of the spindle of the machine tool is normal for automatic feeding of the spindle.

Two, Operation process

1. Workpiece mounting and clamping:

Small artifacts such as to use batch processing, to the bottom of the group of shi to wipe clean, iron light pressure of shi, and yards will be batch correction parallel. A - 2: to direct pressure on large-sized workpiece on the workbench, workpiece of each side of the burr should be clean, at the bottom of the workpiece must level off, then adjust the jig light pressure on the work surface, place the artifacts to pay attention to the journey working shaft, so as not to trip and processing in the not enough influence points.

2. Calibration table and fastening workpiece:

For the workpiece with batch load clamping, the workpiece faces shall be corrected to the allowable tolerance of the machining requirements, and the batch handle shall be tightened after the table is calibrated to ensure the workpiece stability during processing. For large workpiece calibration, the length of the workpiece shall prevail, and the error shall be within 0.02mm.

3. Number of medium and touching: according to the requirements of the drawing, the number of medium and unilateral touching shall be determined.

Points in great notice: in the first points of the sticks in the machine tool spindle head, adjust the spindle rotational speed to 550-650 RPM, lest damage points in great speed is too fast. Use the points in great when it first to check whether points of flexible, otherwise it will affect the points in the precision of points carefully, should take the points in the rod spring shaft and fixed shaft just away from the subject of the event, the electronic scale to zero, and check for at least 2 times. Points after the good side of the workpiece on the other side also operated by the above methods, the points of the two shaft rod coordinates can no longer move in just in time, using electronic foot points of feature points on workpiece.

Note: the operation mode of the split bar is consistent with the above operation. It should be noted that there is another coordinate normalization process after the return to zero.
