CNC Boring and Milling Machine A-4

A-4 CNC Horizontal Boring and Milling Machine

A powerful CNC horizontal boring and milling machine designed for heavy-duty and high-precision machining of large housing parts. The A-4 model, equipped with a fixed facing head, represents the pinnacle of the series in terms of work envelope and is intended for performing the most complex boring, milling, drilling, and tapping operations in single-piece and small-batch production environments.

Key Advantages:

• Maximum Working Area — the machine boasts the largest travels in the A series: table cross travel (X) is 1800 mm, spindle head vertical travel (Y) is 1400 mm, and table longitudinal travel (Z) is 1400 mm, enabling the machining of significantly large components.

• Powerful Spindle Unit — the 110 mm diameter spindle features stepless speed regulation in the range of 10–1100 rpm and an accurate stop function, providing the necessary torque and optimal cutting conditions for heavy-duty operations.

• Fixed Facing Head Included — the machine is equipped with a 650 mm diameter facing head with a speed range of 7–165 rpm. This is a key advantage for machining large parts requiring exceptional rigidity and accuracy in boring operations.

• Closed-Loop Precision Axes — the X, Y, and Z axes are equipped with Spanish FAGOR linear scales, forming a closed-loop control system. This guarantees the highest stability and reliability of positioning accuracy when machining critical components.

• Powerful Independent Drives — each feed axis is driven by an independent AC servo motor directly connected to high-precision ball screws, ensuring high dynamics and positioning accuracy even when working with large workpieces.

• Advanced CNC System — the machine is equipped with an imported CNC system capable of simultaneous 4-axis control, enabling complex multi-coordinate operations, including machining of inclined surfaces and complex contours.

• High-Quality Base Components — the machine's large-scale components (bed, column, table) are designed according to best global practices for premium-class machine tools, possessing a high rigidity margin and potential for future upgrades, guaranteeing long-term geometric stability.

Application Area:

Designed for high-precision and heavy-duty machining of large housing parts in industries with the highest demands for accuracy and productivity: oil and gas engineering (valve bodies, wellhead equipment), chemical and power engineering, and heavy machinery. The presence of the facing head makes it indispensable for boring large-diameter deep holes, machining flanges, surfaces, and complex contours on exceptionally large components.
