Product Description

BTA Deep hole drilling machine

Product Descriptio

Machine Operation:

The machine has the function of drilling, boring, pull boring, trepanning, rolling.


Machine brief: 

1) Drill hole method: Single spindle internal chips removal (BTA method) . This machine is used for the cylindrical workpiece concentric hole processing.


2) Adopt front chips removal method when boring. It means the chips will flow out from holes on the clamp body of headstock front end.


3) Workpiece loading and clamping adopts one-end chuck and another end collect clamping

by manual .


4) The machine used guide rail is double rectangular sliding guide rail , which is processed through medium frequency quenching and precision grinding.


5) Tool feeding adopts servo motor ,servo speed reducer, rack and pinion structure , stepless speed can be realized .


6) 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 .


7) 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 .


8) 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 .


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