Blade Drive
5 H.P. electric with sensor less vector control for smooth acceleration and full torque.
Speed Range
Infinitely variable: 60 to 400 fpm. Blade speed can be automatically set when material is selected.
Tilting Column
For miter cutting up to 60° left and right of vertical. Electrically powered, chain driven, with encoder feedback and Amada Marvel PC3 controller.
0° - 3° Canted Column
Adjustable 0° or 3° forward approach angle, for notching, or increased efficiency in cutting of structural materials. Must specify if 0° or straight column set up is desired as the machines are by default shipped from the factory in 3° Canted Column
Feed Force
Direct Force Sensing Electric Ball Screw Feed which combines more consistent feed force with greater control, 0 - 300 lbs, column travels on re-circulating linear ball ways. Feed pressure can be automatically set when material is selected.
Jammed Blade Protection
Automatically senses resistance as the column returns and stops to prevent blade damage.
Blade
16' Long x 1.25" Wide, .042". One Welded-Edge Band is furnished with each machine as part of standard Start-up supplies.
Blade Guides
Patent pending Rotating Easy Load Combination Carbide and Ball Bearing Roller guides with self tensioning design.
Blade Tension
Hydraulically controlled, 35,000 psi. max. Machine equipped with automatic blade break / blade stall shut off switch.
Upper Blade Guide Arm
Hydraulically positioned and locking, travels on linear guides, controlled through PC3 touch screen control.
Vises
Hydraulic, half stroking with 6.7" High x 11.4" Wide 60° faceplates. Optional variable vise pressure available.
Coolant System
Built-in Flood system, available with Drop Lubrication system, including chip pan with chip removal ramp.
Work-Rest Rollers
One ball bearing roller on the entry side of the machine bed.
Flushing Hose
Washes away chips from hard-to-get-at places reducing clean-up time.
Automatic Bar Feed
The Automatic Bar Feed design features a 48" stroke length with indexing speeds of up to 70 ft./min., and creep speeds of 33 in./min. The bar feed vise is electrically driven and combines precision double ball screws with preloaded re-circulating ball linear guides, resulting in positioning accuracy of ± .005" per index. The vise itself is hydraulically clamped to prevent material slippage. Material can also be fed through the machine manually in both directions using the shuttle vise. Optional outboard and second machine vises are available.
Amada Marvel PC3 Programmable Control
Provides a Programmable Logic Control Unit with an 9" color, touch screen display. The control features graphical part programming with memory for up to 500 jobs and parts, as well as a material selection chart and customizable material library. Both blade speed and feed force are automatically set according to material type for optimal cutting performance. Job features include Inch/Metric capability, out-of-stock shut down device, a fast cut job option and expanded memory storage using removable media. Also includes Jammed Blade Protection that senses resistance as the column returns and stops to prevent blade damage.
Standard Left-to-Right Work Entry
Opposite Hand or Right-to-Left work entry available.
Motors
Main Drive: 5 H.P., Coolant Pump: 1/8 H.P., Hydraulic Pump: 2 H.P.
Controls
IEC fused disconnect switch and magnetic motor starters with overload and low-voltage protection. Power supply provides low voltage control to all push buttons at operator's control panel and machine lighting circuits. PLC control and drives mounted in moisture-tight compartment with vibration isolation mountings. Electrical Equipment conforms to National Electrical Code NFPA 79. The Electrical Control Panel is U.L. Labeled.

Options

Servo Bar Feed with Bullet Nose Cutting
The bar feed vise is upgraded to be servo driven with encoder feedback.
Smart Guide Arm
Automatically positions the guide arm to the part material and prevents guide arm contact with the vises.
Opposite Hand Work Entry
Right-to-Left instead of Left-to-Right normally furnished.
Manual (Hand Crank) Chip Conveyor
Manually operated hand crank “scraper type”
chip conveyor
In place of standard chip ramp. Includes one chip box.
Powered Chip Conveyor
Automatic motorized “scraper type” chip conveyor in place of standard chip ramp. Includes drive motor with gear reduction and automatic shut off.
Variable Vise Pressure Control
Enables hydraulic pressure of work holding vises to be adjusted as required. Includes hydraulic pressure gauge.
