Machine parameters 

1.2 Machining Method
This CNC Gun drilling machine for plate workpiece utilizes the gun drilling process. High-pressure cutting oil is delivered through the inner hole of the drill tube to the cutting edge. The oil then flushes chips out through the V-groove of the tool bar, ensuring efficient deep hole machining for plate workpieces.

1.3 Workpiece Clamping Method
The fixture design for this CNC Gun drilling machine for plate workpiece ensures stable positioning of the plate during high-speed drilling.

1.5 Control System of the CNC Gun drilling machine for plate workpiece

CNC System: GSK (GSK CNC equipment). This system is specifically configured for the CNC Gun drilling machine for plate workpiece to manage complex plate drilling cycles.

X-Axis (Table Transverse Movement): Controlled by a servo motor driving a ball screw on a ball linear guide rail. This axis allows the CNC Gun drilling machine for plate workpiece to reposition accurately across the plate surface.

Z-Axis (Tool Feed Motion): Controlled by a servo motor driving a ball screw on a ball linear guide rail, providing steady feed rates essential for the CNC Gun drilling machine for plate workpiece during deep hole drilling.

1.6 Machine Bed Design for the CNC Gun drilling machine for plate workpiece

Construction: The bed is a resin sand casting, which undergoes a normalizing heat treatment process after casting, providing a stable foundation for the CNC Gun drilling machine for plate workpiece.

Guideways & Transmission: Ball screws and ball linear guides are installed to facilitate precise tool feed. A T-slot worktable is mounted and designed to move transversely (X-axis) under CNC control, allowing the CNC Gun drilling machine for plate workpiece to accommodate various plate sizes.

Structural Rigidity: The bed incorporates V-shaped inclined bars, ensuring the CNC Gun drilling machine for plate workpiece maintains high support strength and resistance to deformation. The outer walls directly support the guide rails, enabling the CNC Gun drilling machine for plate workpiece to withstand significant cutting forces when drilling tough plate materials.

Coolant System: An integrated oil return groove ensures that when the CNC Gun drilling machine for plate workpiece is in operation, the cutting oil drains automatically back into the tank for filtration.

1.7 Drill Box (Spindle Head) of the CNC Gun drilling machine for plate workpiece

Function: The drill box houses the spindle and is responsible for driving the rotation of the cutting tool, a core function of the CNC Gun drilling machine for plate workpiece.

Drive System: A servo spindle motor transmits power via a synchronous belt and pulley system, allowing for precise, stepless speed regulation up to 5000 r/min. This high-speed capability makes the CNC Gun drilling machine for plate workpiece suitable for a wide range of plate materials.

Coolant Delivery: A rotary joint mounted at the rear end of the spindle connects the high-pressure oil line to the rotating spindle, ensuring the CNC Gun drilling machine for plate workpiece maintains a continuous supply of cutting oil to the tool tip.

Design Advantages: The front-mounted drive configuration facilitates easy tool changes and prevents cutting oil from leaking into the motor housing, thereby prolonging the operational life of the CNC Gun drilling machine for plate workpiece.
