  • Koike- Engineered Main Electrical Enclosure: No proprietary components are designed into the Koike main electrical enclosure. Only "off-the-shelf" components are structured for this design. This main electrical enclosure incorporates Sercos-III or EtherCat interface for fast communication between the CNC and electrical components. 18 Amp Bosch/Rexroth drives are used to give the HP required to achieve 1400 IPM rapid traverse speed. Power requirements is 480/3/60 @ 30 Amp.

  • Powerful AC Servo Drives and Ultra Low Backlash Planetary Gearboxes: Powerful 6 HP drives, for X and Y-axis is engineered for precise, smooth and accurate motion for excellent cut quality.

  • Drive System Engagement: Precisely engages the pinion into the rack using dual precision linear bearings. Makes for a long life and accurate machine motion.

  • Large Heavy-duty Rail System: The floor mounted rail systems provides a very rigid foundation for the large 37 KG triple machined rail. This is necessary for very accurate and smooth machine motion. This large heavy duty rail system can be easily expanded to accommodate additional cutting lengths or additional machines on a common rail.

  • Large Diameter Drive Pinions: Large diameter pinions offer accurate and smooth machine motion and are designed to achieve 1400 IPM rapid traverse speeds

  • Drive System Engagement: Precisely engages the pinion into the rack using dual precision linear bearings. Makes for a long life and accurate machine motion.

  • Large 8" Dia Main Roller: Large heavy-duty main saddle rollers provide stability for heavy loads while achieving smooth motion.

  • Large Brass Rail Scrapers: Provide excellent scraping of debris to keep machine motion smooth and stable.

  • Heavy Duty Cross Axis Linear Bearings: Precision linear bearings provide smooth and very accurate motion while providing very heavy load capacities.

  • Rail Axis Cable Carrier: Can be mounted on the floor or overhead (optional)

  • Cross Axis Cable Carrier: A sealed design keeps hoses and cables protected from harsh environments.

  • Machine Tool Testing: All machines tested to ISO 230-2 standards. Machine Motion Accuracy: .015" Accuracy .005" Repeatability (compensated machine motion in 72"; *measured with laser interferometer).

  • Cable and Hose Management: All cable and hoses are properly installed to eliminate twisting and fraying during machine motion.

  • Slave Carriage Band Clamp: Allows easy and accurate manual placement and spacing of tools such as oxy-fuel and plasma torches. 

Plasma Systems & Options

  • Hypertherm HyPerformance/HyDefinition Plasma Systems
    HyPerformance Plasma cuts fine-feature parts with superior quality and consistency while eliminating cost of secondary operations.  The quick disconnect torch makes changing consumables fast and easy.  Long consumable life, dross free edges, minimum angularity and high system reliability maximize productive "arc-on-time".

  • Laser Pointer: Allows operator a visual indicator for plate alignment and torch positioning.
  • 3D-LT Bevel Unit with Koike HD Sensor-THC Height Control
    True focal point technology. This head is designed so motors and gearboxes are receiving maximum protection from the cutting environment. No electrical wires or components near the heat, smoke and dust involved with the cutting process. Designed for simplified alignment and lower maintenance costs.

    Continuous 360° rotation.
    Accuracy +/- .5 Degrees

    Bevel Angle Capability:
    Positive bevel angle: 50°
    Negative bevel angle: 50°

    Bevel Types include:
    A, V, X, Top Y, Bottom Y & K Bevels

  • Manual plasma bevel head
  • Koike Integrated Sensor THC Torch Height Control
        12" (340.8 mm) Lifter Travel
        1,000 IPM Programmable Lifter Speed
        Adjustable stroke retract between cuts
        Dynamic positioning.  
    Collision Detection Mount
        Magnetic integral breakaway for collision detection and system shutdown
        Primary Ohmic contact plate sensing for clean plate
        Secondary plate sensing means for scaled/rusty plate
        Primary and secondary means for lifter homing 
  • TrueHole™ ReadyTrueHole™ Technology founded by Hypertherm® produces a significantly better hole quality than what has been previously possible before using plasma.  This technology was developed for mild steel from gauge to 1" (25 mm) and has been optimized from a 1:1 to a 2:1 diameter to thickness ratio.

    Oxy-Fuel Systems &Options

  • Oxy-Fuel Torch Stations (Up to 8 stations available): Model "G" motorized lifter, 6-inch (150 mm) or 12" (300 mm) stroke at 40 IPM. All stations are controlled from the Operator Console.  Capacitive height control (not shown) allows exact tip to work piece standoff distance (optional).  Automatic ignition (not shown) allows tip ignition automatically through a program or can be executed manually from the Operator Console. 
  • HI-LO Gas Control with Auto Ease-On: Allows high-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.
  • Koike D7 Cutting Tips: Lifetime warranty; designed to reduce backfire and keep both operator and torch safe.
  • Koike Twin Tip Holder: Coverts a single oxy-fuel cutting torch into dual cutting torches. Allows strip cutting and a closer distance between small parts.
  • Koike Torch Bevel Head Attachment: The bevel head attachment is used in place of a Koike cutting tip. It is used for bevel cutting operations, including top and bottom bevel cuts.
