NTA 370 GA: 14.50" Fully-Automatic, Double-Column Cold Saw with Auto-Head Rotation

The NTA 370 GA is a fully automatic CNC hydraulic circular cold saw designed for high-volume, precision cutting of steel bars and profiles where programmable miter control and consistent throughput are required. Its automated cutting cycle, hydraulic clamping system, and CNC-controlled head rotation deliver repeatable accuracy with minimal operator intervention 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 GA 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, unattended production.
- Features fully automatic, programmable head mitering controlled directly from the CNC interface.
- 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 workload while improving consistency across long production runs.

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.
(CYCLE REPEATS UNTIL PROGRAM COMPLETION)

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 high-repeatability cutting cycles.
- Programmable head mitering enables automatic angle changes without manual adjustment.
- Tempered and ground vertical slides ensure stable head movement and long-term accuracy.
- Hydraulic vice with adjustable clamping pressure supports consistent material holding.
- Integrated coolant system maintains blade condition and cut quality.

NTA 370 GA vs. NTA 370:
The NTA 370 GA and the NTA 370 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 GA features fully automatic, CNC-programmable head mitering, allowing miter angles to be entered and changed directly through the control system as part of the cutting program. The NTA 370 uses mechanical head mitering, where angles are set manually using mechanical positioning before the cutting cycle begins. Shops requiring frequent angle changes, automated miter sequences, or programmable angle control typically select the NTA 370 GA, while operations running fixed or infrequently changed angles often choose the mechanical simplicity of the NTA 370.

Specifications:
- Motor power: 3.0 kW.
- Blade speed range: 0–90 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 GA is well suited for production environments requiring automated, high-accuracy cutting of steel bars and profiles with frequent or programmable miter changes. Its CNC-controlled head rotation and fully automatic operation make it an effective solution for batch production, contract cutting, and facilities seeking to maximize throughput while maintaining dimensional consistency.
