Z3550 Universal Radial Drilling Machine

Z3550 Universal Radial Drilling Machine | 50mm Heavy-Duty Multi-Angle Drill

Product Overview:
The Z3550 Universal Radial Drilling Machine is a heavy-duty, industrial-grade equipment designed for complex metalworking. Its most outstanding feature is its exceptional multi-angle processing capability—the headstock can rotate 360° on the carriage, and the radial arm can also rotate 360° around the column axis. This means workpieces can be efficiently drilled at various angles and positions with just a single clamping, significantly improving production efficiency and precision. Featuring a maximum vertical drilling diameter of 50mm (30mm horizontal) and an MT5 spindle taper, it is an ideal choice for large machinery manufacturing, mold processing, and heavy industrial workshops.

Key Features & Advantages:

• High Rigidity & Long-Term Stability: The guide rail, column, and box body are constructed from high-strength cast iron. The castings undergo heat treatment to eliminate internal stress, followed by contact surface quenching. This ensures long-lasting hardness, accuracy, and structural stability of the machine tool.
• Omnidirectional Flexible Machining: Supports ±90° headstock tilt and 360° rotation. With a radial arm lifting distance of 900mm, it easily accommodates irregular workpieces and multi-angle tasks. Spindle feed supports seamless switching between manual and motorized operations.
• Precision Transmission & Low Noise: The headstock transmission gears undergo precision grinding and carburizing/quenching. Paired with high-quality domestic Harbin bearings, the gearbox maintains low noise and strong transmission force even during high-speed cutting (16–1250 r/min).
• Advanced Automatic Lubrication System: Utilizes an internal circulation automatic oil supply system to fully lubricate gears and bearings, effectively solving the traditional issue of insufficient lubrication for top gears and extending equipment lifespan.
• Ultimate Safety Protection Design:Equipped with a spindle travel protection switch to prevent gear or spindle damage from accidental over-feeding.The column safety locking device features an automatic power-off protection system to prevent column strain or worm gear damage if the operator forgets to loosen the lock.Adopts national standard electrical components and a highly sensitive master stop button to guarantee operational safety.
• Durable Precision Lead Screw: Features high-quality lead screws precision-ground by specialized equipment, paired with highly wear-resistant brass nuts, offering twice the service life of standard lead screws.
