TBHD1000 / TBHD1250 CNC High Speed Beam Drilling Line
  • 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.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.

    3.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.

    4.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.

    5.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. 

    6.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.

    7.The workpiece is fixed by hydraulic clamping method. There are five hydraulic cylinders, which are clamped horizontally and vertically. 

    8.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.

    9.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.

    10.Chip collecting box: Universal caster guide, easy to carry.

    11.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. 

    12.The control system is 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.

    13.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.
