Blade Drive

5 HP electric with sensor less vector control for smooth acceleration and full torque.

 

Speed Range Infinitely variable: 60 to 400 FPM (18 to 122 m/min).  Blade speed can be automatically set when material is selected.

  

For miter cutting up to 60o left and right of vertical. Variable speed, inverter driven, electronic tilt- Includes encoder feedback and touch screen display & control, for precision miter positioning. Electrically powered, chain driven, with encoder feedback and AMADA MACHINERY PC3 controller.

  

Adjustable 0 or 3-degree 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.

  

Direct Force Sensing Electric Ball Screw Feed which combines more consistent feed force with greater control, 0 - 300 lbs. (0-1335 N), column travels on re-circulating linear ball ways. Feed pressure can be automatically set when material is selected.

  

Automatically senses resistance as the column returns and stops to prevent blade damage.

  

16’ (4877 mm) long x 1.25" (32 mm) wide, .042" (1.07 mm).  One Welded-Edge Band is furnished with each machine as part of standard Start-up supplies.

  

Patent pending Rotating Easy Load Combination Carbide and Ball Bearing Roller guides with self-tensioning design.

  

Blade Tension  Hydraulically controlled, 35,000 psi. max. (241 MPa).  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” (170 mm) high x 11.4” (290 mm) wide 60o faceplates.  Optional variable vise pressure available.  (Option Code M9A).

  

 Built-in Flood system (Capacity of 26 gallons), available with Drop Lubrication system (requires compressed air connection) (Option Code ML2), including chip pan with chip removal ramp (optional Manual Chip Conveyor available).

  

Work-Rest Rollers One ball bearing roller on the entry side of the machine bed.  

 

Flushing Hose Flushing Hose Washes away chips from hard-to-get-at places reducing clean-up time.

  

 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 (must specify right- or left-hand machine configuration at the time of order - Option Codes F3 & F4).

  

Amada Machinery PC3 Programmable Control®

Provides a Programmable Logic Control Unit with a 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 programming consists of setting the cut-off length, angle and number of pieces to be cut. Additional 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.

  

Opposite Hand or Right-to-Left work entry available (Modification M4A).
