FMC supplies BD1250 series includes BD1250 and BD 1250/9 Beam Processing Center, designed for bigger size steel fabricators desiring to increase profitability and throughput (tons-per-month) in today’s extremely competitive market. BD1250 series drilling system equipped with 3 drilling units(BD1250 has 3 drilling heads while BD1250/9 has 9 drilling heads) which can provide high efficient drilling capacity with wide range of hole diameters, eliminates time-consuming manual beam layout and hole drilling, formerly done by mag drills and/or hydraulic punches. All these 3 drilling units can work simultaneously on the web and flanges of the beam, to ensure maximized working efficiency and save manual labor.
The frame of the machine is square shape high-frequency welded by square pipes and plates. There're one vertical and two horizontal servo-controlled drilling units mounted on the frame. The machine is able to drill the beam simultaneous vertically as well as horizontal.
The drilling spindle can be hydraulic feeding or servo feeding types.
Each spindle's movement is servo-controlled by 2 servo motors which enable the "Fixed Profile, Moving Drilling" ability, which means the profile is fixed in working area and the three drilling spindles can move separately to finish each drilling work. Such technology can reduce the time for repositioning and guarantee better precision.
Being equipped with 3 x 7.5KW powerful spindle motors, the spindle rotation speed can reach Max. 900 rpm. External mist-spray type cooling device protects the drill bits while working and guarantees excellent drilling quality.
There are four groups of vertical roller to catch the beam firmly for feeding.
Duel wheel measuring devices are separately fixed in front and back of the machine to position the beam at the right length.
CNC Controlled marking unit being equipped on the unloading roller to mark pre-programmed numbers/characters up to 1.5mm depth on the flange of the beam. There’re 36 letters on the wheel, from A to Z, and 0 to 9.
The marking wheel’s position can be adjusted manually by a hand wheel.
PC based control console has friendly operation interface, easy and simple for operating. The software program is installed on the control system, which can be connected with the company network, so the DSTV file and DXF file can be downloaded directly from the company’s database to the machine system.
Inside of Electrical Cabinet, the main parts like PLC, modules, servos, etc. are all developed by Siemens, MITSUBISHI or YASKAWA to facilitate program creation and provide appreciable operational savings.
