Amada CNC Controlled Automatic Metal Cutting Band Saw — HFA400CNC

hfa400cnc

Overview

Saw Head Frame

The rigid ‘C’ section frame carries the mountings for the two band wheels, heavy duty planetary gear reducer, the band drive motor and saw guide arm mounting supports.

Iverter Band Speed Controller

The inverter controlled band drive is coupled directly to the Amada designed and built planetary speed reducer. The use of the direct coupled inverter eliminates the power loses from belted variable speed pulleys thus increasing the efficiency of cutting. It also eliminates the maintenance inherent in a variable speed pulley and belt.

Band Wheels & Drive System

The band wheels are cast iron for long, productive life. The drive wheel is mounted on the rotating outer case of the planetary gear reducer. This direct coupling of the drive wheel to the rotating outer case of the reducer provides deflection free torque transfer and ensures the wheel runs true regardless of tension stresses or cutting loads. The inherent high efficiency of the planetary gear reducer means more power is delivered to the blade. The idler wheel spindle assemblies incorporate tapered roller bearings for greater rigidity and long service life. The wheel tracks the blade so that the back of the blade contacts the wheel flange to support the back of the band.

Idler Wheel Motion Detector

The wheel motion detector will turn off the band drive in the case where a blade breaks or is jammed in the work piece. This feature also prevents premature wear on the drive wheel from a stalled band.

Smart Multiple Index

The entire cutting cycle is CNC controlled and based on the operator’s input of the cutting parameters. The multiple index cycle is optimized for the best productivity e.g. a cut length greater than 19.7″ (500 mm.) is indexed by multiple full strokes and the final index stroke is the remaining length.

Band Deviation Monitor  ®

This patented cutting control device can reduce scrap by warning of when the blade is no longer cutting within the set limits. The CNC controller constantly monitors the cutting and blade conditions including the twist of the saw blade. When these exceed the preset parameters in the automatic blade runout detector the machine will cease cutting and indicate the reason for stopping.

Full Stroke Vise Travel

Both sets of work holding vises have full stroke vise cylinders to eliminate the need for the operator to adjust them when changing material sizes.

Split Front Vise

The split work holding vise reduces the butt end remnant to a minimum of 0.3 in. (8 mm.) and minimizes the burr on the cut piece.

Automatic Chip Brush Positioning

The hydraulically driven chip brush is automatically positioned to the blade to ensure the most effective chip removal.

Anti-Vibration Roller

The anti-vibration roller assembly is attached to the left guide. This patented assembly significantly reduces blade vibration particularly when cutting thin sections or high nickel or chromium alloys.

Powered Chip Conveyor

The hydraulically powered chip conveyor auger automatically removes the chips from the saw while draining the cutting fluid back into the fluid reservoir. The automatic chip conveyor greatly reduces cleanup time and enables the machine to run longer without operator cleanup.

Guarding

The saw band is constrained within the heavy gage guarding in all non-cutting areas.
