Combined type BTA and gun drilling Machine

  • The machine is equipped with special cooling system to provide high pressure, high flow and high clean cutting fluid for deep hole drilling.

          Automatic chip conveyor: automatically remove chip and achieve initial oil and chip separation.

         Oil temperature controller: control the temperature of cutting oil and prevent cutting oil from deteriorating               because of high temperature;

         Filtration system: paper tape, mesh type, magnetic rod, precipitation filtration, improve cutting fluid                         cleanliness.

         High pressure pump group: cutting fluid that produces adjustable flow and pressure to supply oil for cutting            tools.

  • Cutting tool infeed is realized by servo motor driving ball screw; Cutting tool rotation is driven by spindle motor; Cutting tool infeed and rotation can be stepless speed regulation.
  • The machine tool has the functions of pressure protection, cooling system level and temperature protection, tool protection, stroke protection and so on.
  • Adopting CNC control mode, it has high degree of automation, strong maneuverability, high working efficiency, high precision, safety and reliability.
