Трехкоординатный станок для глубокого сверления с ружейным сверлом и композитным инструментом BTA

The machine adopts horizontal layout, using gun drill (External chip removal) and BTA (Internal

chip removal) two processing methods, the two processing methods can not be used at the same time. For example, when using gun drill, BTA can not be used; workpiece is clamped on the machine by

chuck and cone disc;cutter tool and workpiece rotate relatively, and cutter toolfeed. When the gun drill and BTA are converted, it is necessary to change the cutter, auxiliary tools and oil circuit manually, so that the conversion of the two processing modes can be realized. The machine adopts double spindle structure. The gun drilling drill box and BTA drill box are assembled on one bracket and share one infeed system.

Machine features:

(1) It has two processing methods: gun drill (external chip removal) and BTA (internal chipremoval). Double spindle structure, one spindle for gun drilling, the other spindle for BTAprocessing. (2) Bed body, box body, worktable and other basic parts are cast with high quality cast iron. (3) Equipped with special cooling system: composed of automatic chip conveyor, oil cooler, filtersystem, high-pressure pump group, etc. (4) Z-axis feeding guide is double rectangular sliding guide with good rigidity. (5) The spindle motor is used to drive the cutter tool rotation, and the feed of the tool is realized by the ball

screw driven by the servo motor. Stepless speed regulation can be realized by rotating and feeding thecutter. (6) Electrical system: it was controlled by CNC system, which can not only program and set up the

automatic processing cycle, but also can adjust manually, point, start and close. (7) The machine has the functions of pressure protection, liquid level and temperature protection of cooling system, tool protection and stroke protection.
