2015 NTC NV4G VERTICAL MACHINING CENTER

Technical Description

The 2015 NTC NV4G is a 3-axis vertical machining center with integrated twin automatic pallet changer manufactured by Komatsu NTC (formerly Nippon Thompson / Nippei Toyama), a Japanese precision machine tool builder. Designed for high-volume production environments, the NV4G incorporates a two-station automatic pallet changer that allows simultaneous machining and workpiece loading to minimize spindle idle time and maximize throughput. Each pallet measures approximately 20.5 by 18.5 inches, providing adequate workholding capacity for a wide range of production parts. The machine delivers a maximum spindle speed of 10,000 RPM through a 10 HP spindle motor, supported by a 25-station arm-type automatic tool changer for flexible tooling setups. Axis travels of approximately 19.68 inches in X, 17.73 inches in Y, and 17.73 inches in Z accommodate medium-size workpieces with good geometric reach. Control is provided by a Fanuc 21i-MA system offering full conversational and ISO G-code programming, canned cycles, and network connectivity. The machine structure is built to Japanese precision standards with guideways suited to the feed rates and cutting forces typical of production milling. Through-spindle coolant at high pressure enhances chip evacuation and tool life in deep-cavity and close-tolerance work. With an overall weight of approximately 17,180 pounds, the NV4G is a substantial production platform well suited to automotive, aerospace, and general precision manufacturing applications requiring continuous multi-shift operation.
