Accurate strength of the company launched the first Taiwan set gun drill, drill pipe, milling, tapping on one of the twin screw drive seven spindle deep hole drilling. The industry's first dual screw drive variable angle technology, unique and novel design, so that the function and performance to achieve the perfect combination, can effectively solve the complex problem of deep hole processing. Precision seven axes machine can be called the deep hole drilling performance of the king!
The industry for the first time using a double screw drive angle technology, in improving the angle range of the same time also reduces the load of the screw, so that the performance of the machine is greatly improved. (patented technology)
The relative horizontal direction of the spindle head can be rotated 20 degrees, down to 35 degrees, compared to the industry to improve the angle range of 35%, can be more rapidly changing perspective, improve the operating efficiency.
Due to the double screw dispersed drilling slide. The load, reducing the loss of screw motion, so as to effectively improve the moving parts of the service life, but also to ensure the accuracy of the persistent.
Double screw driven variable angle bearing platform through design innovation of science, and the Taiwan high precision roller type linear slide. The high rigidity structure can reduce the vibration caused by the rotation of the variable angle, and avoid the phenomenon that the single screw is easy to appear in the structure.
Precision joint Germany's top rotary table manufacturers, production of high precision rotary table in China, the volume of the machine tool for the machine, because the need to understand the deep hole drilling.
The static pressure guide rail has many outstanding advantages compared with the traditional contact rail:

Due to the casting vibration and has good stability, precision machine tool bed adopts high quality casting fine crafted. All bed were senior engineer of scientific structural design, according to the machine tool working conditions and metal material characteristics and casting process on the bed of the geometry and size of careful analysis, using high quality raw materials, combined with the advanced casting technology, strict control of each production process. To ensure that the internal and external quality of the ideal state, and then the two time to eliminate the internal stress, so that the casting is more durable.
Machine tool bed mainly comprises a base, a column, base to protect the stability of the bench and column of the movement, posts are to protect the drilling precision and rigidity, two do foundation for construction of machine tools, but also to ensure the machine can play a powerful performance condition. Ultra to avoid the vibration cause for single tube drilling and milling, the base and the column to the conventional design concept, the geometrical specifications bold increase, and the four Taiwan roller type linear slide rail (model: AMG38. Its stability and heavy sense of second to none in the industry.
According to the cutting force analysis, machine tool spindle in the processing process, in horizontal slide with the workpiece produced strong reaction. The old machine tool slide design the force distribution in the lateral side of the parallel slide, although the precise column in the four roller linear slide rail models (: AMG38, the rigid has superior performance, but according to the roller type linear sliding rail stress principle, lateral a force will not slide performance to the best state. Precision on the performance of the machine is the ultimate pursuit, in the vertical plane of the four rail added a strong roller slide, slide the front main bearing spindle of cutting force and also four rail main bearing horizontal slide out of balance force. After upgrading the feed drilling process in heavy milling and single tube when the obvious speed, accuracy and stability have been further improved.
This machine has a rich function, must be equipped with powerful control system to achieve intelligent operation. Precision with the Taiwan leading control system manufacturers SYNTEC depth cooperation, the exclusive control system, the more innovative design perfect integration into the controller. Precision original image programming, no redundant and complex code programming, simply input processing size, control seven axes machine as simple as the control of the three axes machine, to provide users with a convenient, easy to operate experience.
Optional Japan FANUC (FANUC), Mitsubishi (Mitsubishi), Siemens (Germany), Heidenhain Heidenhain preparation: in order to meet the using habits of the user to the control system, precision and the advanced control system vendors have friendly cooperation. Users can make use of the existing technology, the machine tool control technology for deeper mining.
In order to achieve the real sense of the milling function, the milling cutter is directly mounted on the spindle head, instead of using the auxiliary rod between the milling cutter and the spindle head. To guide the provisional removable deep hole drilling and supporting device, avoid becoming obstacles milling spindle moving. At the same time, considering the convenience of switching between the drilling and milling functions, the precision of the company has used an ingenious design.
Guide sleeve in the process of gun drilling in the drilling process of the drill guide role, need to load the vibration of the drill in the processing, the rigidity of the guide set directly determines the accuracy of the deep hole processing.
Precision for the exclusive use of the square ram structure, by the hydraulic cylinder launch guide sleeve seat at the working position and avoid position switch and the operating system one button control. Square sliding pillow structure compared to the common rail line has a stronger ability of anti vibration, Phi 20mm in large aperture processing or single tube drilling performance is particularly prominent. In the position to avoid, switching speed and rigid structure design are integrated into the latest technology, in the milling processing, guide sleeve seat moved to a position to avoid a spindle can move to the top of the fixed cutter for heavy cutting; in the deep hole processing, a guide sleeve seat moves to the position of the easily gun drill processing and single drilling.
The support frame mainly carries on the support to the middle part of the drill pipe in the process of gun drill. Because of the strong toughness of the drill pipe material, the small diameter gun drill in the high speed running will produce strong shaking, need to set up the support point of the drill pipe diameter of every 40 times.
For the same need to drill milling function switching, avoid the position of the support frame also need to design a reasonable. Ensure switch is convenient, the careful design of two tracks, for a period to avoid the movable track, a for the orbit of a work. In the milling mode, the supporting frame is fixed on the active track, and the main shaft is not caused by obstacles. In the drilling mode, the active track and the moving orbit can be docked, and the supporting frame is pushed onto the moving track, and the supporting role of the gun is drilled. The active track is driven by hydraulic cylinder, and is controlled by the operating system, which is simple and practical.
It is well known that the gun drill is a kind of internal cooling discharge system, high pressure cutting fluid through the hollow drill pipe internal, to reach the head of the drill head cooling lubrication, and the chip from the drill pipe outside the V type groove. Gun drill is generally applicable to Phi 30mm small aperture processing, when the aperture is more than Phi 40mm, has been completely beyond the gun drill processing range, seven - axes machine fusion specializes in large aperture pipe drilling technology, as a gun drill processing technology of, a combination of the two can be swept pore size.
Single drill is a cooling chip mode, and gun drill instead, cutting fluid through delegated oil from the gap between the drill pipe and the outer wall of the workpiece to enter, arrived at the cutter head for lubricating and cooling, and the chip is discharged from the inside of the drill pipe. Large aperture processing is mainly suitable for less than 20mm.
The application of single machine drilling has many advantages:
To make the drilling machine can play a pure milling performance, it must meet the dual needs of light and heavy cutting. Heavy cutting is the test of the performance of the machine tools, such as machine tool rigidity, spindle size, motor power, etc..
This machine adopts BT50 spindle and 18.5kw spindle motor, improve the rigidity of the main shaft and the motor output torque, can easily achieve heavy milling and single drill large diameter processing.
