Amada Automatic Metal Cutting Miter Band Saw — HKA400

hka400

Overview

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.

Band Wheels & Drive System

The inverter controlled band drive motor is directly coupled to the worm gear reducer eliminating friction losses of a variable speed pulley drive. The drive wheel transmission is designed and manufactured by Amada to provide a high efficiency speed reduction, which requires no external cooling to deliver more power to the drive wheel. Band speed is set on using the band speed adjustment knob on the control panel.

Canted Head and Single Column Mounting

The head is canted 8 º to enable the machine to cut rolled sections e.g. I beams or rectangular tubing at significantly faster rates because the blade is never in full contact with the horizontal section of the material. The single column mounting enables the saw guides to be much closer together compared to scissor type machines which improves the cutting performance.

Solid State Sequence Controller

The sequence controller replaces relay logic for greater reliability and speed. It controls all auto and semi-automatic logic functions and machine actions. It includes safety interlocks to prevent inappropriate machine movements.

Full Stroke Clamping Vise

The full stroke clamping vises reduces the operator’s setup time for different widths of material.

Power Positioning of Material for First Cut

The slow speed index vise control enables the operator to more accurately locate the work piece for the first cut. The operator can move the material with the outboard vise until the desired cutting plane is under projected shadow line.

Guarding

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