BTA Deep Hole Trepanning Machine

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. Workpiece and tooling rotate oppositely when machine working .

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) Tooling spindle is driven by 30kw three phase AC motor ,rotary speed range is 40-500r/min, 12 steps .

6) Tooling infeeding adopts servo motor ,servo speed reducer, rack and pinion structure , stepless speed can be realized .

7) Machine equips with three sets drill bar support rest , which are 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 .

8) Oil pressure head can do axial movement controlled by servo system to tighten and loosen the workpiece; The collect is assembled in front end of oil pressure head .

9) Adopt three sets center frame to support the workpiece, workpiece OD range is 60-330mm Upper cover of center frame is opened and closed by manual;Adjust the axial position manually through the rack on machine bed.

10) Headstock drive the workpiece to rotate , three phase AC motor driven, main motor power is 30kw, rotary speed range is 40-500r/min . Three-jaw chuck is assembled in front end of spindle .

11) Coolant system adopts three groups of quantitative pumps, two groups with flow 200L/min, one group with flow 100L/min.
