1. horizontal tube processing Mingtai tube shell type used mainly used in petroleum, chemical, pharmaceutical, power station, nuclear power plants and other industries in deep hole drilling of heat exchanger on the tube plate hole, the maximum diameter of workpiece processing 6000mm (need to flip 180 degrees), maximum drilling depth of 1000mm. The machine tool has high efficiency and good accuracy. The surface roughness of drilling can reach Ra6.3 to Ra3.2, the aperture accuracy is IT9 ~ IT10, and the straightness of hole is 0.3mm/1000mm.
2. located outside chip discharge tube can be used in single chip gun drill or BTA deep hole drilling drill plate, double spindle can work at the same time (adjustable spacing). The DXF format drawings are transformed into NC part programs using programming software. Optimizing drilling sequence and improving drilling efficiency. The machine tool has many kinds of safe automatic protection, and can realize automatic safety monitoring.
3. horizontal tube plate Mingtai deep hole drilling mainly include longitudinal slipway, vertical slide, double spindle feed slide platform and bending plate, hydraulic system, cooling system, lubrication system, electrical system, chip removal etc..
4. horizontal tube plate deep hole drilling is located in horizontal drilling. The main basic parts of machine tools, bed, column, table and bending plate are all high-quality iron castings. After aging treatment, the precision is stable and the seismic resistance is good. The bed is arranged on the longitudinal sliding table for bearing column longitudinal movement; (X) is installed on the column vertical sliding bearing for vertical spindle feed slide (Y) movement; spindle feed sliding table driven spindle feed (Z) movement.
5. horizontal tube plate Mingtai deep hole drilling X, Y, Z three axis adopt imported linear guide pair guide roller, with high load capacity and excellent dynamic performance, seamless, high precision. The three shafts are driven by a preloaded ball screw, which is driven by a servo motor (the Z shaft is decelerated by a high-precision planetary reducer). The X and Y axes are provided with grating ruler and closed loop control, which can greatly improve the positioning accuracy and reliability of the machine tools.
6. horizontal pipe work table and bed located in deep hole drilling is the separation of the influence of the workpiece can not be clamped by the bed vibration. The bent plate workbench clamping workpiece is divided into two parts, spacing can be adjusted to adapt to different workpiece diameter; can also move back and forth, adjusting the distance between the end surface and the guide sleeve end, in order to adapt to the different thickness of workpiece; two inclined plate under the support of the V shape, used for bearing the workpiece, can adjust spacing, in order to adapt to the different diameter of workpiece.
6. horizontal pipe has two main shaft located in deep hole drilling, can work at the same time, improve the efficiency of nearly one times than the single spindle of machine tool. The spindle spacing can be adjusted to accommodate different hole spacing requirements. The machine tool can use BTA drilling, also can use gun drilling, so drilling holes can be gun drilling, drilling large holes can be BTA drilling, greatly improve the drilling aperture range, drilling 7 ~ Phi 45mm hole.
7. horizontal tube with flat chain Mingtai automatic chip removal in deep hole drilling, drill out of the iron chip through the channel to the chain chip, chip full automatic. The coolant is pumped into the coolant tank of the chip remover and is pumped into the magnetic roller, tape filter, filtered and then pumped into the system's coolant tank for recycling. The machine tool is equipped with an industrial refrigerator to cool the coolant, so that the oil temperature can be effectively controlled below 40 degrees, and the stability of drilling can be ensured.
8. horizontal drilling pipe plate Mingtai equipped with automatic lubrication system, can fully periodic lubrication of guide screw, lubricating parts, effectively guarantee the stable operation of the machine tool, improves the service life of each member. This machine CNC system by Taiwan new generation of CNC system (optional Spanish FAGOR system, Japan FANUC System), equipped with electronic handwheel, convenient operation and management. The system can compensate the positioning accuracy of each axis and further improve the positioning accuracy. Using the programming software to transform the CAD drawing into the NC part program and optimize the order of drilling can greatly improve the efficiency.
9. horizontal pipe is provided with a variety of detection functions located in deep hole drilling, including:
1) the X and Y axes are equipped with grating rulers to monitor whether the X and Y axes are accurately completed and feed back to the system to ensure the accuracy of the hole position.
2) spindle feed torque detection. The cutting edge of the drill or the grinding will cause the torque of the feed servo motor to increase. After the system detects, the main shaft stops and exits, waiting for the operator to process. 3) spindle motor torque detection. The cutting edge of the drill or the grinding may cause the motor torque of the spindle to increase. After the system detects, the main shaft stops and exits, waiting for the operator to process. 4) flow measurement. In the process of drilling if the chip will make the coolant flow is reduced, flow measuring instrument signals, CNC system will control the valve to improve the cooling fluid pressure to open the chip, if not open, then wait for the machine to stop drilling, manual processing.
5) pressure detection. Abnormally high or low coolant pressure is detected during drilling, and the spindle stops and returns when this occurs.
6) liquid level detection. A liquid level detection device is provided in the coolant tank, the chip remover and the filter to prevent the coolant from overflowing and the liquid level is too low and the pump can not suck oil.
7) temperature detection. The utility model can prevent the cooling and lubricating effect from lowering because of the high temperature, and further aggravate the abrasion of the cutter. Any of the above cases will be abnormal, and the system alarm will give corresponding hints so that the operator can check the problem.
