3 Axis Gun Drilling Machine
ZKA21 three-axis CNC deep hole drilling machine adopts gun drilling (chip discharge), tool rotation and feed, workpiece fixed on the table, the table can move vertically and horizontally;
ZKA21 three-axis CNC deep hole drilling machine adopts gun drilling (chip discharge), tool rotation and feed, workpiece fixed on the table, the table can move vertically and horizontally; adopts imported or domestic CNC system, with single action and automatic circulation function, three service axes: X axis, Y axis and Z axis, uses servo motor to drive ball screw pair to realize the movement of each axis; The speed and feed of the cutter are stepless speed regulation. The maximum drilling diameter is 20 mm, 30 mm and 40 mm. It has the functions of drilling straight hole, inclined hole, blind hole and step hole. Widely used in automobile, motorcycle industry, mold industry, military industry, aerospace industry, hydraulic valve body, gear shaft and other parts of small deep hole processing.
1. The bed body and box body are made of high-quality cast iron with good rigidity and stability.
2. In the process of drilling deep hole, there is no need to withdraw the cutter halfway.
3. It is controlled by numerical control system with high degree of automation.
4. The rotation and feed of the cutter are stepless speed regulation.
5. X axis: dovetail sliding guide or rolling linear guide (four spindle Series), Y axis: rectangular sliding guide, Z axis: rolling linear guide.
6. It has three servo axes, which can realize the machining of coordinate hole.
7. The main shaft, sliding guide surface and other parts are lubricated automatically and intermittently.
8. The high pressure cooling system adopts frequency conversion motor to drive gear pump, and adopts immersion oil temperature controller.
9. Use automatic chip removal machine to remove chips.
10. It has a variety of automatic monitoring devices.
11. Unique features of the four spindle series: the machine tool adopts double feed system (double Z-axis), each feed system drives a drill pipe box, each drill pipe box is of double spindle structure, the high-pressure pump group of the cooling system is of double pump structure, and the machine tool can process four or two workpieces at the same time. The operator can operate at the front and back sides of the machine tool, which is convenient for operation. The guide rails for drill pipe box movement (Z-axis) are all linear guide rails, the guide rails for table vertical movement (Y-axis) are all double rectangular sliding guide rails, and the guide rails for table horizontal movement (x-axis) are all linear guide rails. Equipped with special cooling system to provide high pressure, large flow and clean cutting oil for deep hole drilling. Equipped with automatic chip conveyor, oil temperature controller, filtration system, high pressure pump set, etc. All the components on the oil tank are assembled as a whole with towing plate, which is convenient for oil tank cleaning and suitable for processing of magnetic and non-magnetic materials. The ball screw driven by servo motor is used to feed the cutter, the spindle motor driven by servo motor is used to rotate the cutter, and the feed and rotation of the cutter can realize stepless speed regulation. The machine tool has the functions of pressure protection, cooling system liquid level and temperature protection, tool protection, stroke protection, etc.
