Product catalog summary

Overview: The NH 450A is a high-speed, high-precision horizontal machining center designed for diverse machining requirements in industries such as automotive, aerospace, and job shops. It features a high-capacity machining space that accommodates both 400 mm and 500 mm pallets.

Specifications: The machine is equipped with a 15,000 rpm IDD spindle, a 1-second auto tool change, and a powerful 3,500 Nm clamping force. It has a stepped casting design on the X-axis for increased rigidity and a dual-wall, symmetrical machine column to minimize thermal deformation.

Design and Construction: The machine base and spindle headstock are made from one-piece FCD600 castings to ensure high rigidity and accuracy. The pallet is also made from FCD600 casting to prevent deformation under heavy loads. Hand-scraping of connection parts ensures long-term cutting accuracy.

Spindle Features: The spindle uses ultra-high precision ceramic ball bearings and a high-efficiency oil cooler system to minimize thermal deformation. It offers a maximum speed of 15,000 rpm, 22 kW power, and 200 Nm torque, suitable for various cutting conditions.

Machining Space: The machine provides a large working envelope with a table size of ø750 mm x 1,000 mm and a maximum load capacity of 500 kg per pallet. It supports both 400 mm and 500 mm pallets.

B-axis Rotary Table: The table is programmable to 1° increments and features a 3,500 Nm clamping force. Air sensors ensure accurate pallet positioning.

Auto Pallet and Tool Change: The machine offers a 7-second pallet change driven by hydraulics and a 1-second tool change cycle. The tool magazine is servo motor-driven for high precision and quick tool finding.

Performance Analysis: Finite Element Analysis (FEM) is used for structural optimization. The machine's power and torque charts indicate its capability to handle various materials and cutting conditions efficiently.

Standard and Optional Accessories: The machine comes with a full chip enclosure, automatic power on/off, spindle air blast, and more. Optional accessories include a 4th axis rotary table, workpiece measurement system, and additional pallets.

General Specifications: The machine has a rapid feedrate of 60 m/min on all axes, a cutting feedrate of 1-20,000 mm/min, and a tool magazine capacity of 40T (optional 60T). It requires a pneumatic pressure of 6 kg/cm² and consumes 45 kVA of power.

Note: The manufacturer reserves the right to modify the design and specifications to improve performance without notice.
