USED DOOSAN HC400 II – 2023

The DOOSAN HC400 II – 2023 is a modern high-performance horizontal machining center engineered for manufacturers seeking exceptional productivity, precision, and automation capability. As an evolution of Doosan’s proven HC Series platform, the HC400 II incorporates advanced machine tool technology, improved spindle performance, faster axis movements, and enhanced automation integration to meet the demands of today’s competitive manufacturing environment.

Designed around a rigid cast iron structure, the HC400 II provides excellent stability during both roughing and finishing operations. The machine’s horizontal spindle orientation delivers superior chip evacuation compared to traditional vertical machining centers. Chips naturally fall away from the cutting zone, reducing heat generation, improving tool life, and maintaining consistent cutting conditions throughout long production cycles. This design is particularly beneficial when machining cast iron, steel, stainless steel, titanium, and other materials that generate significant chip volumes.

The HC400 II is equipped with a dual-pallet automatic pallet changer that dramatically improves machine utilization. While one pallet is being machined, operators can load and unload parts on the second pallet, minimizing downtime and maximizing spindle productivity. This capability makes the machine highly effective for high-volume manufacturing environments and flexible production systems.

A high-speed direct-drive spindle, large-capacity automatic tool changer, rapid traverse rates, and advanced Fanuc control technology allow the HC400 II to achieve excellent cycle times while maintaining tight tolerances. The machine is capable of handling complex multi-sided machining operations in a single setup, reducing fixture costs and improving part accuracy.

Industries that commonly utilize the HC400 II include automotive manufacturing, aerospace production, defense manufacturing, hydraulic equipment manufacturing, energy sector production, industrial machinery manufacturing, agricultural equipment manufacturing, and precision contract machining. Typical applications include transmission housings, gearbox components, hydraulic manifolds, pump bodies, engine components, valve blocks, aerospace structures, and complex production parts requiring multiple machining operations.

The 2023 DOOSAN HC400 II remains highly desirable in the used CNC market because it combines modern technology, automation readiness, exceptional reliability, and strong production capability while offering significant savings compared to purchasing a new machine.
