- Succeed the tool-preset method enabling quick changing of tooling.
The tool holder has few twine-trouble of cut-powder with small-sized, highly hard and new design. -
Tool Size Standard Option OD Tool (Tool Holder) □12.7 5 6 ID Tool ER-16 4 4 Live Tool ER-16 4 3
- Tool Post ($2)
-
4 Position tool
- Center drill
- Drilling
- Tap
- OD tool
- Tool post ($2) controllable independently enables a wide range of optional installations.
NC control model has adopted MITSUBISHI M70A,
whose 8.4" Type and TFT liquid crystal improve the sight performance.
C-axis control function is built-in as standard, which shortens the working time because of no returning to the basic happened when to change from the main spindle to C-axis, by the basic position-loop control of main spindle.
3.7kW oil coolant built-in motor is adopted on Main spindle, and C-axis function is carried on Back main spindle. (Simple belt C-axis)
- 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.
- Option
-
-
- Automatic fire extinguisher
- Automatically put out the fire and breaks the power source when fire happens.
-
- Signal warning light, 3-stage type
- Facilitate confirmation in the distance on how the machine is working.
