CNC Vertical-Horizontal Deep Hole Drilling Machine

Application:


This machine is mainly used for processing holes in heat exchanger of tube shell type in petroleum, chemical, pharmaceutical, thermal power station, nuclear power station and other industries, maximum drilling diameter of workpiece is φ3500mm (need 180°rotaion), and maximum drilling depth is 1000mm. This machine is of high efficiency and high precision, drilling surface roughness can reach Ra3.2 ~ Ra1.6, and precision is IT7 ~ IT9.
 This machine can use outer chip gun drill or inner chip BTA drill, double spindles, can work simultaneously (distance is regulable). Can convert dxf format drawings into NC parts program using programming software. Optimizes drilling sequence and improves drilling efficiency. Equipped with a variety of safety and automatic protection, automatic safety monitoring can be realized.

Structure and configuration:
 

This machine is composed of longitudinal slipway, vertical slipway, double spindle feeding table, working table, curved plate, hydraulic system, cooling system, automatic lubrication system, electrical system, chip conveyor etc.

Specifications:
 

1. This machine is horizontal deep hole drilling machine. Casting lathe bed with high precision and stability, equipped with longitudinal slipway, used for sustaining longitudinal movement of column in X direction; Equipped with vertical slipway   on column, for sustaining vertical movement of feeding slipway in Y direction; movement of spindle in Z direction is driven by spindle feeding slipway.
 2. X, Y, Z axis of machine adopt heavy linear roller guide, which is of high loading capacity and super dynamic response, without clearance and high movement precision. The movement of three axis is driven by pre-loaded ball screw and servo motor (speed reduction in Z axis through high precision reducer). X, Y, Z axis are equipped with grating ruler, closed loop control, can greatly improve the positioning accuracy and reliability of machine.
 3. Working table and lathe bed are separated, avoids influence of lathe bed vibration on clamping workpiece. Working table is made of casting material, with stable precision. Two pieces of curved plates for clamping workpieces, distance is regulable to adapt to different workpiece diameters; also can move forward and Backward to regulate distance between workpiece and end of guide sleeve, in order to adapt different workpiece thickness; Two oblique plates below support of V form, to sustain workpiece, and distance is regulable for adapting different workpiece diameters.
 4. Equipped with two spindles, can work simultaneously, efficiency is doubled in   comparison with single spindle machine. Distance between two spindles is regulable in order to meet the requirements of different hole distances. This machine can use BTA drill or gun drill, in this way, gun drill can drill small holes while BTA drill can big holes, greatly improves the drilling range from φ10~ φ50mm.
 5. This machine is equipped with chain type automatic chip conveyor, chips are conveyed to chip conveyor through chip removal channel, chip removal can complete automatically. Coolant is collected to cooling tank, then is pumped to magnetic roller paper tape filter, after filter is pumped into cooling tank again for recycling use. This machine is also equipped with industrial refrigerating Machine, for cooling the coolant, this way ensures the stability of drilling.
 6. This machine is equipped with automatic lubrication system, for the most adequate lubrication on guide rails, screw and other spares, ensures stability working of machine and prolongs longevity of all spares.
 7. CNC system adopts German Siemens 840D, equipped with manual pulse generator, easy operation and management. System can compensate the positioning accuracy of each axis, for improving positioning precision. Only need to input drawings into system, set center position, system can program automatically, optimize drilling sequence and greatly improve efficiency.
 8. This machine is equipped with many inspection functions, including:

1)  X、Y、Z axis are equipped with grating ruler, which can monitor positioning, feeding,    and then feedback to system, ensures working precision.
2) Spindle feed torque detection. Tipping or sharpening of spindle can increase torque of servo motor, after systematic inspection, spindle can stop and exit for management of operator.
3) Torque inspection of spindle motor. Tipping or sharpening of spindle can increase torque of servo motor, after systematic inspection, spindle can stop and exit for management of operator.
4) Flow measurement. In the process of drilling, if the chip is blocked, the coolant flow rate will be reduced, the flow measuring instrument will give signal, the NC system will control the valve to improve the cooling fluid pressure to open the chip, if not, machine will stop drilling for management of operator.
5) Pressure measurement. the abnormal condition of high or low pressure in the drilling process can be detected, in this condition, Spindle will stop and exit.
6) Liquid level detection. liquid level detection device is arranged in the cooling liquid tank, the chip removing device and the filter, can prevent the overflow and low level of coolant, the pump cannot suck the oil.
7) Temperature measurement. Can prevent high temperature, so that the cooling, Lubrication effect is reduced, exacerbates the tool's wear. Any of the above exceptions, the system alarm will give the corresponding prompt, in order to facilitate the operator to check the problem.
8)Linear guide rail pair, ball screw, servo motor, other driving motor, reducer, internal cold joint (for gun drill), CNC system, hydraulic pump, valves and other important spares, a
ll adopt international famous products, so the machine with high stability, can compare with imported machines, less fault and high power.
