CNC Gantry Movable High Speed H Beam Drilling Machine For Bridge Construction Model BHD1250
China Top Quality CNC Gantry Movable High Speed H Beam Drilling Machine For Bridge Construction Model BHD1250
Application industry:
This machine tool is mainly used for drilling of H-shaped steel. The machine tool uses three high-speed precision drilling spindles to drill the workpiece. It has the characteristics of high machining accuracy and convenient operation. It is an indispensable high-efficiency equipment in the steel structure industry and is widely used in construction, bridges, tower masts and grids. And other industries.
Machine structure:
1．This machine tool is mainly composed of main machine body, cnc feeding system, material conveyor, electrical system, hydraulic system, cooling system, lubrication system, waste box and other parts. The machine tool adopts a fixed bed structure and a movable workpiece structure, which is suitable for the processing of large H-shaped steel, is convenient for continuous production, and has a high degree of automation.
2．The drilling machine body is composed of bed, CNC sliding table components, supporting device, upper pressing device, side pressing device, detection device and so on. The parts of the numerical control sliding table are the fixed side, the moving side and the upper unit numerical control sliding table. The sliding table components are composed of a sliding plate, a sliding table seat, a headstock, a high-speed mechanical spindle, a tool cylinder, a frequency conversion motor, a servo motor, a linear guide, a lead screw, etc., which are used for drilling of H-shaped steel.
3. The lubrication system uses a combination of centralized lubrication and manual lubrication. Centralized lubrication is mainly used for timing and quantitative lubrication of main linear guides and lead screws.
4. The control system of the machine tool is composed of a host computer, PLC and so on.
Programming method: input CAD drawings or processing parameters through USB interface or keyboard to generate processing program. The processing program can be stored, recalled, displayed and communicated at any time according to the part number. The machine tool can not only realize the manual adjustment and control of each processing parameter, but also realize the automatic control processing of the whole process.
