Operation precautions of cnc plate drilling machine

When it comes to cnc plate drilling machines, some people know very much about it, and many people do not know about it. From the point of view of text meaning alone, cnc surface drilling is used to drill, and can also have two major functions of tapping and milling function, so what do we need to know about the operation of the cnc plate drilling machine?

1, the high pressure center of the internal cooling cutting operation form is preferred to recommend, can effectively avoid chip accumulation, blade damage and machining surface quality and other problems, the external cooling method in the drilling process needs to pay attention to the drilling depth, must not exceed 1.5D, drilling depth is necessary to use the pecking drilling method. Do not drill holes on inclined, medium-concave, and uneven surfaces.

2, if the parts have reserved holes, then it should be noted that the aperture processed by CNC plane drilling should not exceed 1/4 of the size of the finished product, otherwise it will divert the bit. When drilling parts with intersecting holes or multiple layers stacked together, it is necessary to reduce the feed rate to about 1/3 of the recommended value. During the machining process, the blade with the drilling effect should be used with the blade with the tip arc radius greater than 0.4mm to improve the service life of the tool.

3. When the CNC gantry drilling milling center is in the working state, it is necessary for the operator to check the load status of the spindle at any time and avoid the spindle load value exceeding 100%; The wear condition of other blades should also be confirmed in time, and the switch and color of the chip and the load value of the spindle can be discharged to confirm the wear condition of the blade.

4. Check the blade of CNC gantry drilling milling center regularly, so long as it can effectively ensure the accuracy requirements of the machining hole and improve the quality and processing efficiency of the product. It not only improves the utilization rate of the machine tool, but also improves the utilization rate of the tool and reduces the processing cost of the product.

In general, the rational use of CNC gantry drilling milling center can bring great assistance to our processing and production, but it is worth noting that in the daily operation, we should also do the basic maintenance and maintenance work at any time.
