Centering machine is called centering machining center, also can be called spindle box mobile CNC automatic lathe, economic turning and milling compound machine tool or longitudinal cutting lathe. Belong to the precision processing equipment, can be completed at the same time vehicles, milling, drilling, boring, composite processing, such as attack, engraving, etc., mainly for batch processing of precision hardware, shaft shaped non-standard parts. Centering machine processing manufacturers in the use of centering machine to carry out parts processing, in the processing of deep holes, generally in 30 - 35mm up and down, in the process of processing, if the processing hole depth reaches 5 times the diameter, or even 10 times the case, the processing hole depth parallelism are slash. However, if the threaded hole is processed, the relationship between the hole depth and the processing diameter is also 10 times, which is not suitable for processing on the heart machine. At the practical application level, the accuracy of the centering machine is high and meets various accuracy requirements in use. And about the centering machine to carry out deep hole processing level, the machine tool will have high pressure cutting fluid equipment, so that the cutting fluid can be very smoothly sprayed into the hole inside, so that the temperature of the drill bit to further reduce the precision pin processing factory for the development of cutting time occurred when the slag easy to discharge. This can further improve the processing accuracy and service life of various tools in the equipment.
