Three Coordinate Gun Drilling Machine For Square Workpiece

Technical Overview of the Three Coordinate Gun Drilling Machine

1.1 Core Processing Technology
The Three Coordinate Gun Drilling Machine adopts external chip removal gun drilling technology, ensuring high-precision and efficient deep-hole machining.

1.2 Application Scope
This Three Coordinate Gun Drilling Machine is designed for machining workpieces with coordinate-distributed holes, including through holes, blind holes, and stepped holes.

1.3 Structural Integrity and Stability
Key components of the Three Coordinate Gun Drilling Machine-such as the bed body, column, worktable, column base, and gearbox-are constructed from high-grade cast iron (HT300). Each casting undergoes two-stage aging treatment to fully eliminate internal stress, ensuring long-term structural stability and precision retention.

1.4 Five-Axis Servo Drive System
The Three Coordinate Gun Drilling Machine is equipped with five independently controlled servo axes:

X-Axis: Drives lateral workpiece movement. It features ball linear guides, a servo motor coupled with a reducer to drive the ball screw, and CNC-controlled motion. The guide rail is protected by a telescopic stainless steel guard.

Y-Axis: Drives tool movement. Utilizes ball linear guides, a brake-equipped servo motor driving the ball screw via a reducer, CNC control, and a counterweight balance system.

Z-Axis: Controls tool feed motion. Incorporates ball linear guides, a servo motor directly driving the ball screw, and full CNC operation.

W-Axis: Adjusts the distance between the column and worktable. Fitted with double rectangular slideways, precision-ground and hardened, driven by a servo motor and reducer, and protected by a telescopic stainless steel cover. Motion is CNC-controlled.

B-Axis: Provides workpiece indexing via a CNC rotary table capable of arbitrary angular positioning, fully integrated into the machine's CNC system.

1.5 High-Performance Cooling and Filtration System
The Three Coordinate Gun Drilling Machine includes a dedicated cooling system that delivers high-pressure, high-flow, and ultra-clean cutting fluid essential for deep-hole gun drilling operations. The system comprises an automatic chip conveyor, an oil temperature controller, a multi-stage filtration system for fluid cleanliness, a high-pressure pump unit, and a main coolant tank.
