BTA Deep Hole Drilling Machine
BTA Deep Hole Drilling Machine
BTA is an external cooling and internal chip removing type of deep hole drilling. The drill head and drill stem is connected by screw. The rigidity is higher than gun drill and the drilling efficiency is 2-4 times higher than gun drilling. BTA deep hole drilling requires higher oil pressure and sealing between workpiece and guide sleeve. This type of deep hole drilling is suitable for constant and heavy volume drilling because of high efficiency. Limited by inner space of drill stem, BTA drilling is mainly used in drilling diameter Φ16 – 65mm of deep hole, the max drilling hole diameter can reach 130mm.
  • If you are wondering how to choose bta deep hole drilling machine, bta drilling machine, bta machine, if you are checking products price, or if you are looking for high-quality products for sale, please feel free to contact Golden Stone Machinery, we are one of the leading China bta deep hole drilling machine manufacturers equipped with professional factory.
