Combined Type BTA And Gun Drilling Machine
The machine adopts horizontal layout, using gun drill (External chip removal) and BTA (Internal chip removal) two processing methods, the two processing methods can not be used at the same time
Description
Combined type BTA and gun drilling Machine
Machine brief :
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 fluidcleanliness.
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.
