Product Description

TBHD1250 CNC High Speed Beam Drilling Line(Siemens PLC) 
(With Auto Line Scribing Function)
Application:
This machine is mainly used for processing holes on H-beam, channel beam with high speed, the positioning, feeding of three spindles are all driven by servo motor. It adopts spindle servo motor, controls by CNC system, and in-feeding by CNC carriage, high efficiency, and high precision; and it is wildly used in construction, bridge and other industries.

Product Feature:

1. The whole machine is optimized integrated design, with high quality machine body and drilling units, which ensure high stability and high rigidity when high speed drilling. This machine is mainly composed of main machine, CNC sliding table (3), drilling spindle box (3), clamping device, detection device, cooling system, scrap box, hydraulic station, lubrication system, Tool Magazine(optional), marking unit (optional).
2. The main machine is welded by square pipe. The structure of main machine is strengthened where the stress is greater. After welding, artificial aging treatment was carried out. All these ensure the stability of the main machine and then ensure accuracy of the whole machine.
3. There are three CNC sliding tables: fixed side CNC sliding table, movable side CNC sliding table and intermediate CNC sliding table. The three sliding tables are similar in structure and are composed of sliding plate, sliding table and servo drive system.
4. There are six CNC axes on the three sliding tables, including three feeding CNC axes and three positioning CNC axes. Each CNC axle is guided by precise linear rolling guide, driven by AC servo motor and ball screw, which ensures positioning accuracy.
5. There are three spindle boxes, which are mounted on three NC sliding tables for horizontal and vertical drilling. Each drilling spindle box can drill both separately and simultaneously.
6. Used high-speed precision spindle from Taiwan's well-known brand, model BT, which can meet the using demand of both hard alloy and high-speed steel drill. Every CNC axes are guided by the heavy loading roller linear guide, driven by the servo motor and roller screw which ensure the rigidity and positional accuracy.
7. Also equips with hydraulic tool cylinder, using hydraulic -disc spring to do automatic tool de-clamping, tool pulling, with tool status monitoring device to check the tool clamping and effective safety co-locking protection device. Easy to change tools. The spindle is driven by spindle servo and timing belt, reducing ratio i=2 , spindle speed is 0~3000r/min, large rotation speed range.
8. The workpiece is fixed by hydraulic clamping method. There are five hydraulic cylinders, which are clamped horizontally and vertically. Horizontal clamping consists of fixed side datum and moving side
9. clamping, fixed side datum is fixed, moving side clamping is driven by large cylinder sliding table, guided by linear guide rail, moving towards the fixed side to clamp the workpiece horizontally; vertical clamping is on both fixed side and moving side, and each cylinder drives the pressure bar to move up and down in four positions. The workpiece is clamped vertically.
10. The machine is fed by a NC carriage. The NC carriage is decelerated by the servo motor through the reducer and then passes through the gear rack to driven a laser alignment device. When the workpiece is fed in, the workpiece can be detected and then fed back to realize the precise positioning of the workpiece.
11. Cooling system: using air-fog cooling, with the internal and external cooling. Each drilling spindle box is equipped with its own external cooling nozzle and internal cooling joint, which can be selected according to the needs of drilling holes. Internal and external cooling can be used independently or simultaneously.
12. Chip collecting box: Universal caster guide, easy to carry.
13. 13. Machine equips with auto lubrication system, automatic pump the lubrication oil into and do fully lubrication for each and every part of linear guide, ball screw nuts and every rolling bearings etc at regular time, no need manual lubrication, increase the parts life and save time. All the lubrication pump and units are using famous brands.
    14. Tool Magazine(optional): Installed 3 inline type tool magazine, which realize the automatic tool change, also meet the demand of drilling multiple diameter's hole. Oil spray and air spray cooling, has inner cooling and outer cooling efficacy.
    15. Marking unit (optional): The marking unit adopts the disc typing structure, 0-9, A-Z, 36 characters are distributed on the disc, and the position is selected by the servo motor.
    16. The CNC control system is the Siemens PLC. Strong anti-interference, high precision, because of the digital communication, thus overcome the defect of easy be interference in traditional pulse analog transmission.
    17. In order to ensure the accuracy, reliability and stability of transmission system, electrical system, hydraulic system, all the key components are from international famous brand.
    18. This machine has the function of scribing, which can replace the manual work. At the same time of drilling, the position of the plate to be welded in the next process can be marked with the scribing tool, which saves time and effort, and has better precision. The scribing tool is made of Korean cutter, which can be installed on the side fixed handle. The whole set of scribing tool is made of replaceable carbide scribing drill in the center, which is durable. In addition, a set of spring system is specially designed, which can recover the resistance of drill bit when machining uneven surface. hydraulic system is for auto tool device of ram type drilling box,Horizontal clamping, vertical clamping, side pushing and power raceway, unified oil supply; all the hydraulic units are from imported brands or joint venture companies, for easy maintenance and solving oil leaking, all the design adopts accumulative valves.If marking unit is equipped, there is also an independent hydraulic station for marking unit action.

15. The main advantage of high speed CNC drilling TBHD1250, it's high speed drilling, rotation speed can reach 3000rpm.
    Due to TBHD1250 using the carbide drill bits, single hole processing efficiency increased to more than 5 times than the normal speed machine, the overall production efficiency more than 2 times than the normal machine. For example: 22 mm diameter, thickness 20 mm workpiece, TSWZ series drilling one hole need about 30 seconds, TBHD1250 series can be controlled within 5 seconds.
