The machine is mainly composed of bed (worktable), gantry, vertical ram-type drilling spindle, hydraulic system, cooling system, auto-lubricating system, CNC system, electrical system and chip-conveyor etc.
▲ One or more movable slides are equipped on the cross beam of gantry. The slides are guided by two liner roller guide pairs and driven by AC servo motor and precise ball screw respectively.
▲ The slides on the cross beam are equipped with vertical CNC feeding ram-type drilling spindle, which adopts special conversion motor. Stroke self-controlled drilling unit can make the drill approach work piece rapidly, when the drill touches the work piece, it can change the feeding speed immediately to preset working speed automatically. After the hole is drilled through, the drill returns automatically and rapidly.
▲Heavy-load liner roller guide pairs are equipped on two sides of the machine bed respectively. The longitudinal movement of the gantry’s two sides is driven synchronously via AC servo motor and precise ball screw.
▲Hydraulic system, used to clamp and release the work piece, keep enough clamping force during drilling process.
▲ It adopts FAGOR CNC system, equipped with RS232 interface and LCD screen.
▲ Programming software based on Windows platform with CAD connection, fast and convenient programming and visual preview. It can recognize the flange or plate automatically.
