Deep hole drilling and boring machine
The machine tool is specialized in processing cylindrical deep-hole workpiece equipment, machine bed is with good rigidity and accuracy. Equipped with 2 sets of adjustable roller center frame, it can also adapt to the machining of large workpiece's inner hole.The spindle speed range is wide, and the feed system is driven by AC servo motor, which can meet the needs of various deep hole processing technology.The tightening of oil pressure head and workpiece adopts servo tightening method.
Machine bed:
The guide rail adopts double flat guide rail design, and the machine bed guide rail width is 800mm. The material adopts high quality cast iron HT300. Artificial aging treatment, medium frequency quenching treatment on the surface of guide rail, quenching depth 2-3 mm, quenching hardness HRC45-50. High precision and good abrasion resistance. Precision rack drive bracket is installed in the middle of the guide rail ,It is used for infeeding and rapid movement of the bracket. 
Headstock and chuck : Headstock 21grade speed regulation, speed range 3.15-315 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.A button station on the front side of the headstock can control the forward movement and stop of the spindle.The headstock is fixed structure, the main motor is fixed on the bed body, the transmission rigidity is good, and the aseismic property is good.
The cage type chuck body is mainly fixed on the front end of the spindle, and a 630mm three jaw chuck is mounted on the chuck body.
