Description

The NTA 370 is a fully automatic CNC hydraulic circular cold saw designed for high-volume, precision cutting of steel bars and profiles where repeatability, stability, and controlled automation are required. Its automated cutting cycle, hydraulic clamping system, and mechanically indexed head rotation deliver consistent results in demanding production environments.

In standard cold saw sizing practice, the 370mm blade capacity places this machine in the 14.5″ class. This positions the NTA 370 above standard 14″ machines, providing increased cutting capacity while remaining compatible with commonly available large-format cold saw blades.

– Executes a fully automatic CNC cutting cycle for repeatable production output.
– Uses mechanically indexed head mitering for stable, repeatable angle positioning.
– Operates within the widely recognized 14.5″ blade class for higher-capacity cold saw applications.
– Maintains cut quality through hydraulic clamping, controlled feed, and integrated coolant delivery.
– Reduces operator involvement while maintaining predictable, consistent results.

Operating Cycle:
Cycle start is initiated by pressing the start button. Once activated, the machine performs the following operations automatically during each cutting cycle:
1. Automatic material feed to the programmed length.
2. Closing of the fixed vice and activation of the blade motor with coolant delivery.
3. Cutting head descends under controlled feed until the cut is completed.
4. The head rises, blade rotation and coolant stop, and the carriage returns to position.
5. The vice opens and the material advances for the next cut.

Cutting Capacities:
– Round Material at 0°: 3.15″ (80mm).
– Round Material at 45° Right: 3.15″ (80mm).
– Round Material at 45° Left: 3.15″ (80mm).

– Square Material at 0°: 3.15″ × 3.15″ (80mm × 80mm).
– Square Material at 45° Right: 3.15″ × 3.15″ (80mm × 80mm).
– Square Material at 45° Left: 3.15″ × 3.15″ (80mm × 80mm).

Key Features:
– Fully automatic CNC hydraulic operation for consistent, repeatable cutting cycles.
– Mechanical head mitering with fixed positioning ensures robust, stable angle setup.
– Tempered and ground vertical slides maintain head alignment throughout the cutting stroke.
– Hydraulic vice with adjustable clamping pressure supports consistent material holding.
– Integrated coolant system maintains blade condition and cut quality.

NTA 370 vs. NTA 370 GA:
The NTA 370 and the NTA 370 GA share the same blade class, cutting capacity, and fully automatic cutting cycle, but they differ in how miter angles are set and controlled. The NTA 370 uses mechanical head mitering, where angles are set manually using fixed mechanical positioning before the cutting cycle begins. The NTA 370 GA features fully automatic, CNC-programmable head mitering, allowing miter angles to be entered and adjusted directly through the control system as part of the cutting program. Shops running consistent angles or prioritizing mechanical simplicity often select the NTA 370, while operations requiring frequent or programmable angle changes typically choose the GA version.

Specifications:
– Motor power: 3.0 kW.
– Blade speed range: 25–50 RPM
– Blade diameter (class): 14.5″.
– Blade diameter (actual): 14.57″ (370mm).
– Material feed stroke: 39.37″ (1000mm).
– Overall dimensions: 137.80″ × 47.24″ × 74.80″ (3500mm × 1200mm × 1900mm).
– Approximate weight: 2,139 lbs. (970kg).

Common Uses:
The NTA 370 is well suited for production environments performing automated, repeatable cutting of steel bars and profiles at fixed or infrequently changed angles. Its mechanical head mitering and fully automatic cycle make it an effective solution for facilities seeking reliable throughput with straightforward, durable angle setup.
