BTA blind hole drilling and boring machine

BTA blind hole drilling and boring machine
Product Description

Heavy duty BTA blind hole  drilling and boring machine for solid bar

Product Description

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 servo main motor , hydraulic two-gear variable speed, stepless speed can be achieved within each gear . Main motor power 55kw, max. speed of low gear is 400r/min, max. speed of high gear is 800r/min .

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

7) Machine equips with two sets 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 .

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 one set center frame to support the workpiece, workpiece OD range is ÃƒÆ’ŽÂ¦60~Φ350mm 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 , servo main motor driven , hydraulic two-gear variable speed, can realize speed stepless within each gear, Main motor power 55kw, max. speed of low gear is 400r/min, max. speed of high gear is 800r/min , Three-jaw chuck is assembled in front end of spindle .

11) Adopts one chain plate chips removal devices to remove the cutting chips .

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