Description:
The 420 Dual-Spindle CNC Drill-Tap-Mill Machine is a compact and efficient multi-functional machine tool designed for small and medium-sized parts processing. It integrates drilling, tapping, and milling functions in one unit, widely used in electronics, hardware, automotive accessories, and mold manufacturing industries. With dual independent spindles, it can complete different processes simultaneously, significantly improving production efficiency.

Equipped with a Tianjin Taisen 4-axis system, the machine features stable operation and easy programming, suitable for both single-piece and batch production. The 1.5 kW 4-pole milling spindle provides sufficient power for drilling and light milling, while the 6 N·m servo tapping spindle ensures precise thread forming with a maximum tapping diameter of M12 and tapping speed up to 600 r/min.

The X/Y/Z axes adopt 20 flange guide rails and 25 ball screws, driven by high-precision servo motors, ensuring smooth movement and reliable positioning accuracy. The folding armored cover effectively protects the guide rails and ball screws from chips and coolant, extending the service life of key components.

With a compact footprint of 1100×900×1800 mm and a net weight of 360 kg, the machine is easy to install and suitable for small workshop environments. The dual-spindle design allows users to perform drilling and tapping operations without changing tools, reducing auxiliary time and improving processing consistency. The machine supports stepless spindle speed adjustment from 1 to 3000 r/min, adapting to different workpiece materials and processing requirements.

Standard components include Omron relays, diaphragm couplings, and high-quality motor mounts, ensuring long-term stable operation with low maintenance requirements. The machine is an ideal choice for small enterprises and processing workshops looking to improve production efficiency while saving equipment investment costs.
