Product Description

1. Overview:
This machine made by frame, longitudinal slide, stand column, vertical slide, drilling unit, cnc control system, hydraulic system, pneumatic system, automatic lubrication system, spray cooling system and other parts.
Frame and structure are welded assembly, the sliding plates and main shaft boxes are made of high quality cast iron, the materials are treated with thermal aging to completely elimination, the internal stress and ensure whole machine rigidity and precision.

2. Product Feature:

1. The horizontal machine with left & right part, left part made by 3 steel plates welded and aging process section. Bottom surface install several adjustable sizing block.
2. Working table under foundation, with uniformly-spaced support bars(with T slot for clamp workpieces)
3. Moveable gantry made by steel plates welded and aging processed 2 stand column and 1 beam for relieving internal pressure, each stand column and beam install 2 heavy load anchor linear guide and Ball screw pair, driven by the servo motor, making three sets of CNC slide and power head in the gantry horizontal and vertical direction.

4. The machine has a single ram-type drilling power head, that is, left and right horizontal drilling power head and vertical drilling power head to meet the requirements of drilling at the same time on three sides of the workpiece. Drilling power head using Taiwan's precision high-speed spindle, high precision rotation, good rigidity; Frequency conversion motor + synchronous belt drive, low speed and high torque, can withstand heavy cutting load, can also be suitable for high-speed machining of carbide cutting tools. Spindle with a hydraulic knife, loading and unloading tool is very convenient. In order to ensure the power head and vertical slide up and down the movement of light and flexibility, the use of hydraulic balance, that is, both sides of the power head skateboard and hydraulic cylinder were connected according to the actual weight of the power head to determine the oil pressure to achieve effective balance power Head weight, to ensure the accuracy of processing and stability purposes.
 
5. The machine has a total of eight feed axes. The longitudinal movement of the main shaft along the bed is X1 and X2 axis. The positioning movement of the three skids along the column is U, V and W axis respectively, and the three ram driving motions are 1, 2 and 3 axes respectively. The movement of the three feed shafts is guided by the ultra-high bearing capacity heavy-duty linear roller guide. In order to ensure the smoothness of movement and positioning accuracy, X-axis servo motor plus precision gear box and backlash gears on both sides of the drive, linear ball guide, in order to achieve the gantry of the dual drive without backlash movement. The bed is reserved for the grating mounting surface, as a special configuration, matched by the customer. U, V, W axis and 1,2,3 axis are used servo motor plus ball screw drive, linear ball guide, to ensure their positioning accuracy.
6. CNC machine tools using FAGOR8070 system, and equipped with color LCD and network interface. Can control the two power head at the same time or independent work, do not affect each other. Operation interface with man-machine dialogue, automatic alarm, fault self-diagnosis, processing program preview and other functions, you can field keyboard input, you can also off-site PC input, easy to operate.

7. Machine power head with a laser knife device, with electronic hand wheel operation, easy alignment of the workpiece on the baseline, processing, CNC system can be automatically processed.
8. The machine is equipped with a dry cooling system for the cooling of the head, each of which is equipped with their own external cooling nozzles and internal cooling joints, according to the need to select the hole, cold and cold can be alone or at the same time use. The system is driven by compressed air, the internal cooling medium for the micro-plant cutting oil, continuous supply of oil mist for dry cooling, cold cooling with ordinary cutting fluid, adjustable nozzle control the water state, to achieve the best production.
9. Machine precision linear roller guide, precision ball screw, gear rack and other high-precision sports are equipped with automatic lubrication system. Automatic lubrication pump output pressure oil, quantitative oiler oil into the oil, oil chamber filled with oil after the system pressure rose to 1.4--1.375Mpa, the system pressure switch pull, pump shutdown, unloading valve unloading at the same time, Pipeline oil pressure dropped to 0.2Mpa below, quantitative oiler began to point to the lubrication point, to complete a filling. As the quantitative oiler fuel supply precision, and the system pressure can be detected, reliable oil to ensure that the surface of the movement of a layer of oil film, reduce friction and wear, to ensure the accuracy and life of the machine.
10. The hydraulic system is mounted on the rear of the gantry and moves along with the gantry to provide pressure oil for the knife on the top of the power box, which makes the removal of the tool extremely easy. It is also used for the locking of the gantry and the gravity balance of the power box. The system is equipped with oil temperature cooling device, used to control the oil temperature, improve the service life of hydraulic components and hydraulic system reliability. Hydraulic components adopting reliable, hydraulic components of installation size in line with international standards, with versatility to match user different requirements.


11. Pneumatic system from the external air supply to provide compressed air (1Mpa), mainly to complete the two aspects of work: a, after unloading the tool, the compressed air from the rear of the hollow spindle into the spindle, especially the spindle head cone hole Clean the tool so that it can be clamped again. b, for the machine with the dry cooling system to provide air.
12. The equipment is equipped with a chip conveyor, for the flat chain, iron and residual coolant from the table on the ramp fell to the chip conveyor, iron chip by the chip conveyor to the end of the chip car Inside, regular cleaning can be, can greatly improve the work site environment.
13. In order to ensure the reliability and durability of the machine, the key parts of the machine, are using world-renowned brand manufacturers products.
Note: The picture is only for reference, please make the object as the standard.
