The Model CTB400 band Saw Machine is developed for high production, accuracy, and economic cutting.

This state of the art machine is specifically designed to use the multifaceted Amada carbide band saw blade.

The combination of these two has achieved an excess of 15 square inches per minute cutting rates, surface finishes in the range of 62 RMS while holding accuracy's well within the + - 0.002 per inch of diameter.

The world's first CNC OPTIMAL CUTTING CONTROL (patent pending) presets feeds and speeds according to material specification.

This unit has 229 factory installed material specs, with 100 available for custom materials. Feeds and speeds are automatically set to achieve the most economical cutting with the highest productivity possible, while maintain noise levels below 85 decibels.

Productivity Features
Saw Head Frame
  • The rigid 'C' section frame carries the mountings for the two band wheels, heavy duty worm drive gear reducer, the band drive motor and saw guide arm mounting supports. The saw head is supported and guided by LM linear bearings. The bearing rail is mounted on the head's vertical center of gravity for better stability.
Drive Wheel Transmission
  • The drive wheel worm gear transmission is designed and built by Amada to provide high efficiency speed reduction, which requires no external cooling, to deliver more power to the large diameter drive flange which is mounted on the drive wheel. This flange ensures that this developed torque is transferred to the blade with no strobing, enabling the machine to efficiently cut high alloys as well as free machining materials. The entire drive assembly up to the wheel is sealed against chips or cutting fluid to for long maintenance free operation.
CNC Saw Feed Control
  • The CNC controller has 220 materials pre-programmed and provision for 100 user materials. The controller will automatically vary the feed rate of the saw head for materials with a changing cross section to ensure the fastest cutting time and best surface finish. When using Amada Triple Chip Carbide blade on a changing cross section, the cutting rate will be significantly faster than conventional HSS blades with an exceptional surface finish not available with normal band saw blades.
Blade Deviation Monitor
  • The CNC controller constantly monitors the cutting and blade conditions including the twist of the saw blade. The maximum allowable twist is specified for each direction. When either of these values is exceed, the preset parameters in the automatic blade runout detector the machine will cease cutting and indicate the reason for stopping.
Smart Multiple Index
  • The NC micro processor controls the index cycle enabling the machine to cut different lengths in sequence from the same work piece and provides a 'Smart Multiple Index' cycle for cut lengths greater than the single index stroke of 11.8 in. (300 mm). The index cycle makes full length index passes.
Multiple Index
  • The machine control has the capability to make up to 2 index passes giving a maximum cut length of 31.5 in. (800 mm.) in automatic.
Split Front Vise
  • The work holding vise is split so that it clamps the work piece on both sides of the cutting plane. This additional support in front of the cutting plane minimizes the burr on the cut pieces. will cease cutting and indicate the reason for stopping.
