Product Details

Used for making deephole parts, roughness usually can reach Ra 0.4, it adopts BTA method for drilling, and use push-boring method

T2120 Deephole Drilling&Boring Machine

　　The machine is special equipment for machining deep cylindrical hole of workpieces.It can be perfectly suited for drilling and boring through holes, blind and step holes in workpieces;sush as, apindle of various kinds of machines, many kinds of hydraulic oil cylinders and cylinders.Tt can perform not only drilling and boring, but also rolling pressing.The method of the internal-removal chip is adopted in drilling.The machine is strong in rigidity of the bed, high in precision, andwide in spindle speed range Feed system is driven by Japan A.C. Servo feeding motor.It is suitable for various processing methods of machining deepholes.Fixture of the guide carriage and clamping force of the workpiece are performed by hydraulic device and indicated by meter.
Various change-model products of the series can be supplied according to users requirement.
