TZ2150B Oil Drill Collar Processing Machine

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 design fully considers the process characteristics and particularity of deep hole drilling of oil drill collars. On the premise of ensuring the processing quality, it strives to improve the processing efficiency and the pleasantness of the machine tool operation, and it is convenient to load and unload the workpiece. This machine tool is suitable for ultra-long workpieces. The length-diameter ratio of the drilling inner hole can reach 150-200, 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 of 42CrMo, 35CrMo, 4145 alloy materials after quenching and tempering, and the hardness of the workpiece is generally not greater than HB320. The machine tool is equipped with a headstock and a drill pipe box. During processing, the tool and the workpiece can rotate relative to each other at the same time, which effectively improves the processing efficiency. The machine tool is equipped with an annular steady rest and two reinforced special steady rests, which can effectively ensure the relative stability of the workpiece when it is rotated. And the workpiece is straightened during processing (bending amount <2mm), no need to process the outer circle and end face, and can be directly drilled and pinned, saving auxiliary time.

Since it was put on the market, it has been well received by the majority of users, and it is the first choice of domestic and foreign oil drilling collar manufacturers.
