- MITSUBISHI CNC
- Machining program memory capacity is increased more than double (600m→1,280m). Computing power advancement, decreased cycle time by New PLC Engine loading. And internal compensating unit is improved 1nm (20J: 10nm), which makes the machining process more smoothly.
- Operation Panel
- Manual operation panel and CNC operation panel are separated. Setup time can be decreased by operation performance.
- Tool presetter
- 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
- Stops the machine automatically when the pressure of coolant oil decreases below specified level.
- 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
- Protects electronic circuit from high voltage to shutdown noise such as lightning.
- 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
- Stops the machine detecting defects in the main spindle when standard load and actual main spindle load are different.
- 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)
- Stops the machine automatically detecting broken tap while processing the edge face of the tap.
- Optional Accessories
-
-
- Automatic fire extinguisher
- Automatically put out the fire and breaks the power source when fire happens.
-
- Oil mist collector
- Collects floating mist and helps for better working environment.
-
- Signal warning light, 3-stage type
- Facilitate confirmation in the distance on how the machine is working.
