ツールプリセッター

Tool presetter : Optional
Nomura’s original “Tool Presetters” increase machine utilization through “off machine” tool presetting of quick change tooling, reducing the time required to replace and adjust tools up to 60%. The Nomura Tool Presetter is a microscope-type unit that presets a turning tool to the same gauge length. This makes programming and operation much easier. It also makes it unnecessary to “touch off” tools after they are mounted on the machine, making the tool change process a 2-screw operation. With this unit, tooling can be set up even while the machine is running parts. Tooling can be quickly changed, and you can get back into operation fast.
Safety System (Standard Equipment)
  • Coolant oil cut-off detecton
    Coolant oil cut-off detecton
    Stops the machine automatically when the pressure of coolant oil decreases below specified level.
  • Door safety interlock switch
    Door safety interlock switch
    Causes the main power breaker to trip and the power to shut down when electric cabinet cover is opened.
  • Lightning surge protection function
    Lightning surge protection function
    Protects electronic circuit from high voltage to shutdown noise such as lightning.
  • Auto power interception
    Auto power interception
    Switches off the power breaker on the machine automatically when the machine is stopped during the automatic operation for any reason.
  • Main spindle load detection mode
    Main spindle load detection mode
    Stops the machine detecting defects in the main spindle when standard load and actual main spindle load are different.
  • Cut-off tool breakage detector
    Cut-off tool breakage detector
    Stops the machine automatically detecting materials that cannot be completely cut-off due to the breakage failure of the parting tool.
  • Tap breakage detector(Option)
    Tap breakage detector(Option)
    Stops the machine automatically detecting broken tap while processing the edge face of the tap.
Option
  • Oil mist collector
    Oil mist collector
    Collects floating mist and helps for better working environment.
