Our independently developed, designed, and manufactured ZSK21100BX10M deep hole drilling machine has been fully put into production at the customers site.
Product Brief
This machine tool can complete the drilling of inner holes in petroleum drill collars. During processing, the tool and workpiece rotate relative to each other simultaneously, or only the tool rotates or only the workpiece rotates. The internal chip removal process (BTA method) is used for drilling. The cutting fluid reaches the cutting area through the gap between the oil injector, tool holder, and the drilled hole of the workpiece, lubricates and cools the cutting area, and wraps the chips into the chip box through the drill rod inner hole and chip hopper. The CNC device is used to control the sequence of various movements and actions of the machine tool, which can accurately control the depth of the drilling hole. After straightening the workpiece (with a bending amount less than 2mm), there is no need to machine the outer circle and end face, and drilling can be carried out directly after installation, saving auxiliary work time.
