Our company's TSK2150X12m heavy-duty deep hole drilling and boring machine passed the strict inspection by the buyer's personnel, and was successfully packed and shipped to Tianjin Port on March 16, 2011, ready to be shipped to Iranian user factories. This machine tool is completely independently developed, designed and produced by our company according to the special needs of users. Both domestically and internationally, it has created a precedent for the perfect combination of heavy-duty deep hole drilling and boring machines and lathes. The machine has the functions of drilling, boring, expanding, rolling and turning, which can realize one-time clamping and complete multiple processes at the same time. It also saves the cost of a 12-meter lathe for customers. Mainly used for processing the inner hole and outer circle of petroleum drill collars, seamless steel pipes and other workpieces.
