High speed CNC H beam Drilling Machine Model BHD700

About High speed CNC H beam Drilling Machine Model BHD700

Components of CNC Drilling Machine Line:

The drilling machine is mainly composed of main machine body, cnc feeding system, out-feeding conveyor, cooling system, hydraulic system, pneumatic system, lubrication system, electrical system, and waste material car.   The production line adopts a fixed bed structure and a movable workpiece structure.   The three-dimensional drill of this structure is convenient for automated production.

Main machine body:

It mainly consists of a base, a bed, a movable sliding table, a headstock, an upper pressing device, a side pressing device and a row-type tool magazine.

The bed has good rigidity and stability, can withstand the load and vibration generated by high-speed machining, and ensure the accuracy of the machine tool.

There are a total of 3 headstocks installed on the main machine, namely the fixed side, the mobile side and the upper unit headstock, for drilling in the horizontal and vertical directions respectively.   Each headstock can be operated independently, and can also complete drilling operations at the same time, which greatly improves production efficiency.   Each headstock has a set of BT40 high-speed mechanical spindles, and the corresponding row-type tool magazine can install up to 4 diameters of drills (when there is no tool on the spindle), and 4 different apertures can be automatically processed when the workpiece is clamped once. .   The spindle feed is driven by a servo motor, which can realize fast forward, work forward, and fast rewind through program control;   the spindle motor is driven by a spindle servo motor, the speed is steplessly adjusted, and the speed range is wide.

Three headstock units are hung on the bed, and each headstock unit is driven by two sets of servo motors to realize the horizontal and vertical movement of the headstock, which is driven by ball screws and guided by precision linear rolling guides.   This equipment compresses the workpiece in two directions during the drilling process.   Above the workpiece, there is an oil cylinder driving a pressing mechanism to press the workpiece on the horizontal support roller, and an oil cylinder driving a pressing mechanism to press the workpiece from the side.

Innovative Drilling Technology

The BHD700 model utilizes a precision-controlled 3-axis CNC system for high-speed, high-accuracy drilling on H-beams, channels, and box beams. The automatic tool changer and precision linear guideways streamline the entire operation for increased throughput and reduced downtime.


Seamless Automation and Safety

Transitioning between fully automatic and manual override modes, the BHD700 promises both productivity and operator control. Safety measures like emergency stops and protective guards, combined with a user-friendly touch panel, ensure reliable and secure work conditions.


Optimized for Heavy-Duty Applications

With a 4.5 kW main spindle motor and capacity for H-beams up to 700 mm wide, the BHD700 is ideal for demanding structural steel processing. Its high rigidity structure and robust clamping system maintain stability and accuracy, even under continuous, intensive operation.
