Deep hole drilling &boring machine

Deep hole drilling &boring 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 hole in workpiece such as spindle of various kinds of machines, many kinds of hydraulic oil cylinders and steam cylinders.

The method of the internal-removal chip is adopted in drilling. The machine is strong in rigidity of the bed, high in precision an d wide in spindle speed range.It is suitable for various processing methods of machining of machin e deep hole. Fixture of the guide various change-model products of the series can be supplied according to users ' requirement.

Machine equips with one set drill bar support rest , which is assembled with hitching

and pulling structure, pull the drill bar support rest back to original position when the processing finished and returning tooling ; Can also adjust the axial position manually through the rack on machine bed ,but rack and pinion structure should be released by releasing structure under the machine working condition .

Oil pressure head can do axial movement driven by motor to reduce the labor force . The collect is assembled in front end of oil pressure head .

Headstock drive the workpiece to rotate , Three-phase asynchronous motor to drive, main motor power 30kw. Three-jaw chuck is assembled in front end of chuck body .

Coolant system adopts three groups of quantitative pumps, with flow 100L/min, 200L/min, 400L/min .
