  • General Fabricators and the alike
Mastergraph Extreme Benefits
  • Plasma & Oxy-fuel cutting process capatible
Standard Equipment
  • Operator Console: Hard-wired switches for powering machine, selecting oxy-fuel station, operation and E-stop button.  Swivels to the left or right for better ergonomic machine operation. 
  • Emergency Stop Button: E-stop button quickly and safely shuts off machine motion and cutting process, including oxy-fuel gases to the torches.
  • Linear Way and Heat Shields: Wide profile replaceable linear roundway provides for a smooth and accurate cutting motion.  Heavy duty heat shields protect machine from heat and sparks.
  • Rear Shelf Component Covers: Prevents damage to components from harsh cutting environment such as, smoke, sparks, and dirt (shown with optional Hi-Lo Oxyfuel gas system).
  • Limit Switches: Used for over-travel as well as homing of the machine.
  • Rail Axis Cable Carrier: Can be mounted on the floor or overhead.  A sealed design keeps hoses and cables protected from harsh environments. 
  • Large Diameter Drive Pinions: Large diameter pinions offer accurate and smooth machine motion.
  • Maintenance Free Guide Rollers: Sealed bearings for linear roundway.
  • Main Rail Saddle Heat Shields: Protects main beam and rails when cutting heavy metal.
  • Heavy Duty H-Beam and Rail Design: Provides highly accurate symmetry for the basis of precision cutting and smooth motion.  Allows expansion of rail length and use of common rail for two or more machines.
  • Air Tensioning System: For proper pinion-to-rack engagement; extends pinion and rack life.
  • Slave Carriage Band Clamp: Allows easy and accurate placement and spacing of tools such as, oxy-fuel and plasma torches; allows mirror cutting of parts.
  • Heavy Duty Slave Carriage Steel Band: Endless loop stainless steel band keeps motion of transverse axis accurate and smoth when using multiple torches. 
  • Koike-Engineered Main Electrical Enclosure: Offers "off-the-shelf" components including Yaskawa drives
Optional CNC Controls
  • Hypertherm® EDGE Pro
  • ITT Burny 10LCD 

Plasma Systems & Options

  • Koike Aronson offers three brands of plasma cutting system:Hypertherm, Victor Thermal Dynamics and Burny Kaliburn..
  • UltraSharp Technology: This system has been calibrated to ensure the highest quality in hole cutting
  • TrueHole™by Hypertherm®: produces significant hole quality
  • 3D-LT Bevel Unit: rotates in a continuous 360 degree pattern, can perform postive and negative bevel angles of 50 degrees.
  • Hypertherm ArcGlide Torch
  • INOVA Precision Arc Voltage
  • Manual Plasma Bevel Station

Oxy-Fuel Systems & Options

  • Auto Ignitor: Safely ignites oxy-fuel torches with the convenience of never having to leave operator station
  • Torch Bevel Head Attachment: the bevel head attachment is used in place of the a Koike cutting tip.   
  • Twin Tip Holder: Coverts a signle oxy-fuel cutting torch into dual cutting torches.  Allows strip cutting and a closer distance between small parts.  
  • D7 Cutting Tips: High quality, Faster Cutting, Gas Savings, Durable 
  • Oxy-Fuel Torch Stations
  • Pneumatic Dot-Peen Stamp Marker Station: Carbide tipped variable speed punch for marking bend lines, layout lines, drill locations and lettering/numbering as small as 1/4" high
  • Hi-Lo Oxy-Fuel Gas System with Auto Ease-On : Allows hi-lo preheat for fast preheating of plate and superior cutting quality.  Features auto ease-on pierce control for cut oxygen. Allows for precise piercing on thicker plate.

Tables Options

  • Zoned Downdraft Cutting Table
  • Water Cutting Table

Other Options 

  • Fume Extraction Unit - made by Donaldson ExtraLife™
  • Safety Light Curtain: will shut-off machine if anything comes withint eh path of the light curtain while machine is in motion.
