- Engraving Machine Type: CNC Drilling Machine for Beam
- Origin: Chengdu, China
- Trademark: VISTA
- HS Code: 8459210000
BDM Series widely used in the fields of construction, bridge, tower mast, and space truss, mainly for the drilling of H-beam, U-beam and Box-beam. It adopt seven servo-control CNC axes(three for flange drilling) and three stepless transducer controlled rotation speed of spindle. All the holes on its 3 sides can be completed after the H-beam getting thought the machine once, with high efficiency and high position precision. It is the necessary equipment for guarantying the quantity in the steel structure.
1. The machine has good rigidity, optimized structure, higher strength, better anti-shake and more beautiful preview.
2. The machine has 3 power heads: One vertical drilling head for the drilling on the web plate, and two horizontal drilling power heads on the two side of the machine for the drilling on the flange plates. Each power head can do continuous drilling in the feed-in direction 640mm after once feeding until to complete all the drilling process of one hole group. It is connected by taper shank module between drill bit and spindle.
3. These 3 drilling spindles can be controlled separately. They can drill simultaneously and also separately.
4. Comparing with the carriage conveyor, the servo motor driving to feed in with the examining by the two encoders can process longer work piece without the length limitation of carriage conveyor.
5. Movable side and upper unit is each equipped with a detecting cylinder with raster, which can realize the control symmetry of web and flange plate of H-beam and meet customers' processing requirements.
6. For the spindle of power head is controlled by the hydraulic sensing, it can alternate among fast feed-in, working feed-in, fast feed-out automatically, no need to set the length of drill bit and the thickness of work pieces. Therefore the working efficiency is improved greatly.
7. The spindle motors and deceleration motors of power heads which are imported from the SEW company of Germany guarantee the good performance, high reliability, and low noise of our products.
8. It can be programmed automatically with the friendly software interface. For the programming software is independent to the host computer, it can install in any computer to realized the programming in different places. The programming can be copied directly or sent to the equipment by internet for using.
9. The drilling machine has reasonable electric control system and famous industrial computer. 7 axes controlling make it stable, reliable and convenient for operation.
10. Classic components, the hydraulic components, all the electric components (include button switch etc), ball screw, and linear guide rail are the products of famous companies in home and abroad.
III. Introduction about the trolley Conveyor system
The trolley conveyor is equipped on the feeding side of CNC 3-D drilling machine. It is used for transporting the workpiece(H-beam, U-beam and Box-beam) into drilling machine.
