Deep hole drilling machine

Drill box:Drill box 12 grades speed regulation, speed range 60-1000 r/min. The box body is made of high quality cast iron with artificial aging. All gears are made of high quality medium carbon steel or low carbon alloy steel with quenching hardness of about HRC48.Grinding process to improve working accuracy and wear resistance.

Drill box has 2 kinds of structure design : Fixed and rotary. The drill box can be locked if there is no need of drill bar rotating

Oil pressure head: Function: 1) input coolant to the workpiece and sealing ; 2) Guide bush can be installed in it .to guide the drill bit ; 3) support the drill bar; the oil pressure head front mounted machine cooling and hydraulic display instrument, so that the machine can be dynamically displayed in processing, easy for the operator to judge the processing of the machine.

Cutting oil supply system: It mainly consists of oil tank, pump station, oil chute, chip car and oil return tank. Three sets pump group with 3 sets gear pump, According to the different processing aperture, through the knob on the button station, we can get 200 L/min, 500 L/min, 800 L/min three kinds of flow.The tank is placed on the ground without digging holes. Oil tank thickness is 3mm.
