High Speed CNC Beam Drilling and Marking Machine Line Model BHD1000/BHD1250
Used for the drilling processing of H-shape steel, box beam and
channel steel of steel structure, bridge, three dimensional garage
and petrol platform. The positioning and feed of the three drilling
headstocks are all driven by the servo motor, CNC system control,
CNC trolley feeding, high efficiency and high precision.
Machine structure and configuration:
1. Mainly composed of bed, CNC slide (3), drilling headstock (3),
clamping device, detection device, cooling system and iron filings
2. The bed is welded by square steel pipe, and the structure of the
bed is strengthened in the place where the force is strong. The
welding is completed and artificial aging treatment is carried out,
which ensures the stability of the bed and ensures the stability of
the bed. The accuracy of the entire machine is very high.
3. There are three CNC sliding tables, which are fixed-side CNC
sliding table, moving-side CNC sliding table and intermediate CNC
sliding table. The three sliding tables are similar in structure,
and are composed of slide, sliding table and servo drive system.
There are 6 CNC axes on the three slides, including 3 feed CNC axes
and 3 positioning CNC axes. Each CNC axis is guided by precision
linear rolling guide, driven by AC servo motor + ball screw.
Guaranteed its positioning accuracy.
4. There are 3 drilling headstocks, which are mounted on three CNC
slides for horizontal and vertical drilling. Each drilling
headstock can be drilled separately or simultaneously.
5. The spindle adopts a precision spindle with high rotation
precision and good rigidity. Equipped with BT40 taper hole, it is
convenient to change the tool. It can be used for both twisted and
twisted carbide drills. The main shaft is driven by variable
frequency speed control main motor, which has a wide range of
applications. The speed can be continuously variable in a wide
range to meet various speed requirements.
6. The workpiece is fixed by hydraulic clamping. There are five
hydraulic cylinders for horizontal clamping and vertical clamping.
The horizontal clamping is composed of the fixed side reference and
the moving side clamping. The fixed side reference is fixed. The
moving side clamping is driven by the large cylinder to move the
sliding table. The linear guide is guided to move to the fixed side
to clamp the workpiece horizontally tight; the vertical direction
is clamped on the fixed side and the moving side. Each of the
cylinders drives the pressure bar to move up and down at four
positions to clamp the workpiece in the vertical direction.
7. The machine is equipped with workpiece width detection and web
height detection device, which can effectively compensate the
deformation of the workpiece and ensure the processing accuracy.
Both of these detection devices adopt the cable encoder, which is
easy to install and reliable.
8. The machine tool adopts the trolley to feed, and the feeding
trolley is driven by the servo motor through the gear reducer and
then driven by the rack and pinion. A laser alignment device is
installed on the bed, and the workpiece can be detected when the
workpiece is fed, and then feedback can be performed to achieve
precise positioning of the workpiece.
9. Cooling system: It adopts aerosol cooling and has the functions
of internal cooling and external cooling. Each drilling headstock
is equipped with its own external cooling nozzle and internal
cooling joint, which can be selected according to the drilling
requirements. Internal and external cooling can be used alone or
10. Iron filings box: Guided by universal casters, it is easy to
11. This machine needs to be equipped with the Korean YESTOOL brand
taper shank and knives, which are provided by the customer.
