CNC Boring and Milling Machine P-4

P-4 CNC Horizontal Boring and Milling Machine

A powerful CNC horizontal boring and milling machine with a moving table, designed for heavy-duty and high-precision machining of large-scale components. The P-4 model combines an extended work envelope, a powerful spindle unit with a facing head, and precision axes, delivering exceptional productivity, accuracy, and stability in boring, milling, drilling, and tapping operations for both one-off and serial production.

Key Advantages:

• Maximum Working Envelope — the machine features significant axis travels: table longitudinal travel (Z) — 1400 mm, table cross travel (X) — 1800 mm, spindle head vertical travel (Y) — 1600 mm. The spindle extension (W) is 600 mm, and the facing head slide travel (U) is 200 mm, enabling the machining of workpieces of various sizes and configurations.

• Powerful Spindle Unit with Facing Head — the machine is equipped with a 110 mm diameter spindle with stepless speed regulation from 10 to 1500 rpm and a torque of 1029 N·m. The 670 mm diameter facing head, with speeds from 7 to 165 rpm and a slide travel of 200 mm, allows large-diameter boring and machining of large components.

• High Productivity and Power — the spindle is driven by a 40 kW motor, providing high torque for heavy cutting. The maximum drilling diameter is 65 mm, and the maximum boring diameter is 300 mm.

• High-Precision Rotary Table — the machine features a built-in CNC rotary table (B-axis) with 360° positioning, allowing multi-sided machining of complex parts in a single setup, improving accuracy and reducing auxiliary time.

• Precision Positioning Accuracy — high positioning accuracy (0.018 mm for linear axes) and repeatability (0.012 mm) ensure stable machining quality for critical components.

• High Table Load Capacity — the work table, measuring 1400×1250 mm with T-slots, can support loads up to 5000 kg, allowing the machining of large and heavy workpieces.

Application Area:

Designed for high-precision and heavy-duty machining of large housing parts, brackets, plates, and other workpieces across various industries: heavy engineering, power engineering, shipbuilding, production of large pumps and compressors, and oil and gas equipment. The presence of the facing head makes this machine indispensable for large-diameter boring and machining complex parts that demand high accuracy and productivity.
