BTA Deep Hole Drills are used on dedicated machinery where the coolant is induced through a pressure head and the chips are then evacuated through the center of the drill and the drill tube. Tube dampers are used to support the drill tube, prevent vibration and distortion, and work steadies support the workpiece if required.
Ejector drills are used on conventional and CNC-type machines. They use an inducer to feed coolant between the inner and outer twin-tube system with the chips being ejected through the center of the inner tube. With CNC machines now utilizing high-pressure coolant, We can offer alternatives to the ejector system.
Solid drill heads with brazed carbide inserts are available from Ø7.76mm to Ø65mm. These heads can be reground and re-tipped / re-coated but are considered a consumable item and therefore have a limited life. Indexable inserted drill heads are available from Ø15mm upward and allow quick insert changes and on heads above Ø25mm the ability to adjust the cutting diameter.
T2120G T2120G/1 BTA drilling machine:
Purpose of machine: This machine is a special machine for processing cylindrical deep hole parts. It is suitable for drilling and boring cylindrical deep hole parts. When boring, oil feeder is used to supply oil. Through the cutting area, the chips are discharged to the chip hopper at the head of the machine. During drilling, the internal chip removal (BTA) method is adopted, i.e. oil is supplied by the oil feeder. Through the cutting area, the chips are discharged from the inside of the drill pipe to the chip removal hopper at the back of the bed.
The machine is controlled by PLC, the reciprocating motion of the oil feeder and the feed carriage is controlled by servo motor, and the transmission is driven by rack in the middle of the two guide rails, which ensures the accuracy and rigidity of the feed transmission in the ultra long motion. Protection is installed on both sides of the bed, and the above ground oil tank structure is adopted to improve the machine environment. The machine tool can be equipped with two sets of automatic or manual high-efficiency tools, which greatly improves the machining efficiency of the machine tool.
The machine is a kind of deep hole boring machine with convenient operation, control, high efficiency and environmental protection.

TK2150 TK2250 CNC deep hole boring machine |
TK2150 CNC deep hole boring machine is a new generation of CNC deep hole boring machine developed by our company, which embodies our company's leading position in domestic research and development of deep hole boring machine. Compared with the T2250A CNC deep hole boring machine series, the TK2250 CNC deep hole boring machine series has the following characteristics and advantages: It adopts the SIEMENS 802D CNC system produced by the German Siemens company. 2. High-precision helical racks are installed on both sides of the carriage bed; Siemens servo motors are used as feed motors. The feed motor slows down through the reduction gearbox and meshes with the racks on both sides of the machine bed to achieve the feed motion. 3. The servomotor is used to control the movement of the oil injector, which makes the operation more convenient. TK2250 CNC deep hole boring machine does not have the drilling function, the boring bar box is optional, and the remaining functions are the same as TK2150 CNC deep hole drilling and boring machine. |
