TZ2150B oil drill collar processing machine is a special deep hole drilling machine designed and manufactured by our company for the inner hole drilling of oil drill collars. The process characteristics and particularity of oil drill collar deep hole drilling are fully considered in the design, and on the premise of ensuring the processing quality, we strive to improve the processing efficiency and the pleasantness of machine operation, and it is convenient to load and unload workpieces. This machine tool is suitable for super long workpieces The length-to-diameter ratio of the drilled inner hole can reach 150-200mm, and the maximum drilling depth of the machine tool is 10 meters to 15 meters. This machine tool is suitable for deep hole drilling and boring processing of 42CrMo, 35CrMo, and 4145 alloy materials after quenching and tempering. The hardness of the workpiece is generally not greater than HB320. The machine tool is equipped with a bed head box and a drill rod box. During processing, the tool and the workpiece can be rotated relatively at the same time, which effectively improves the processing efficiency. The machine tool is equipped with a circular center frame and two reinforced special center frames, which can effectively ensure the relative stability of the processed workpiece when it rotates. In addition, the workpiece is straightened (bending amount <2mm) during processing, and there is no need to process the outer circle and end face, and the drilling and pin processing can be directly performed, saving auxiliary time. Since it was put on the market, it has received unanimous praise from users and is the first choice of domestic and foreign oil drill collar manufacturers.
