Introduction of zk21d series of machine: this series of drills adopt the method of internal chip removal for drilling and machining. There are two types of drill pipe: single pipe and double pipes. The single tube is BTA Deep hole drill and the double tubes is ejetor drill.
The drill bit is usually connected with the drill pipe by screw thread, and its connecting part is circular section, its rigidity is higher than gun drill, and its production efficiency is 2-4 times of gun drill. However, limited by the chip removal space of the tool system, it is mainly used for the machining of holes with diameter ￠ ≥ 16mm, and the tools can not be reground. The workpiece rotates or is fixed, and the drill pipe rotates and feeds.
The feed guide adopts rolling guide, which has high hardness, stable movement and long precision. There are many kinds of workpiece clamping forms, such as double chuck, chuck with hydraulic center frame, inner cone top plate, etc.
The preferred equipment for deep hole machining of large quantities of rotary shaft parts is suitable for mining machinery, machine tools, molds and other industries.
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. |
