Floor Layout 【 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 1mm (20J: 10mm), 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.

【【 ツールプリセッター Tool presetter 】 】オプション装備

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 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- 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. ▼ Other direct-mounted tool style Y Sets the X/Y axis Sets the Z axis Setting Setting Safety System (Standard Equipment) 0 0.5 1.0 Cutting Production 0 0.5 1.0 Z Tool X Tool Coolant oil cut-off detector Main spindle load detection mode Microscope Stops the machine automatically when the pressure of coolant Stops the machine detecting defects in the main spindle when 20min. 30min. 30min. oil decreases below specified level. standard load and actual main spindle load are different. tool holder tool holder (Inside Microscope) ▼ NOMURA Tool holder style Door safety interlock switch (Inside Microscope) Setting tool(*No adjustment) Causes the main power breaker to trip and the power to shut down when electric cabinet cover is opened.
