Overview
The YCM NV408A is a compact vertical machining center from Yeong Chin Machinery Industries, designed to maximize machining capability within a small installation footprint. The NV designation reflects YCM's compact-series branding, and the 408A's 400 mm X-axis travel places it in the sub-compact VMC category alongside Brother Speedio, Fanuc Robodrill, and Haas Mini Mill as a shop-floor-efficient solution for toolrooms, prototype shops, and high-mix low-volume production cells.
Despite its compact dimensions, the NV408A is built to YCM's full production standard with Meehanite cast iron construction, linear roller guideways, and a quality spindle assembly — not a reduced-specification economy machine. The machine's small footprint of approximately 1,600 x 1,800 mm allows it to be positioned where larger VMCs cannot fit, enabling shops to utilize previously unusable floor corners or install multiple NV408A units in a row for parallel production of the same family of small parts.
The spindle runs at 12,000 RPM in the standard BT 40 configuration, with 15,000 RPM available as an option — adequate for small-diameter end milling in aluminum, steel, and stainless at appropriate cutting speeds. Spindle power of 11 kW (15 hp) is well-matched to the BT 40 taper and the small-to-medium cutting loads the NV408A is designed for. A 20-tool arm-type ATC provides tool capacity sufficient for most toolroom and prototype programs. The table measures 700 x 400 mm and supports workpiece loads up to 400 kg.
Fanuc 0i-MF Plus control is standard. The NV408A's pricing is typically in the $55,000–$80,000 range, making it one of YCM's most accessible VMC offerings. For shops that need a capable, space-efficient VMC without the capital commitment of a full-size machine, the NV408A represents a practical choice with the backing of YCM's established dealer network in North America, Europe, and Asia.

Strengths & Limitations
Strengths
- Compact 1,600 x 1,800 mm footprint installs in spaces where larger VMCs cannot fit, maximizing floor space utilization in small shops and enabling multi-machine cell configurations in medium shops
- YCM production-quality construction at a compact machine price point — buyers get the same cast iron base, linear guideways, and quality spindle as YCM's larger machines rather than economy construction common in low-cost compact VMCs
- 36 m/min rapids on all axes is competitive with mid-range VMCs, minimizing non-cutting time even in complex programs with frequent tool changes
- $55,000–$80,000 price range offers a clear step up in brand and build quality from Haas Mini Mill while staying within the same budget tier
Limitations
- 400 mm X travel and 700 x 400 mm table are limiting for shops that occasionally need to machine larger parts — frequent trips to a larger machine defeat the purpose of a compact satellite VMC
- 20-tool ATC is adequate for most compact VMC programs but will be constraining for complex prismatic parts requiring more than 20 tools
- At $55,000–$80,000 the NV408A competes directly against the Haas Mini Mill, which carries substantially better brand awareness and service network density in North America — YCM must be sold on merit against this institutional advantage

Frequently Asked Questions
01
The Haas Mini Mill offers 356 x 305 x 254 mm travels, slightly smaller than the NV408A's 400 x 410 x 450 mm. The NV408A provides a modestly larger work envelope and YCM's build quality at a similar price. The Haas Mini Mill has a significant advantage in North American service coverage through Haas's national franchise network. For buyers in Haas-dense service areas, the Mini Mill's service advantage is real. For buyers willing to research YCM dealer quality in their region, the NV408A often delivers more capability at the same price.
02
Yes. The NV408A's Fanuc 0i-MF Plus control supports DNC networking, FTP program transfer, and machine ready/cycle complete signals for robot integration. For lights-out automation with a collaborative or industrial robot, the machine door must be assessed for automatic operation — YCM offers automatic door options that integrate with robot cell controllers. A parts catcher and chip conveyor should also be specified for unattended operation.
03
Yes. The YCM NV408A supports 4th axis rotary table installation via the Fanuc 0i-MF Plus control's 4th axis capability. Given the 700 x 400 mm table dimensions, compact 4th axis units (100–160 mm face plate) are well-suited to the machine. The 400 kg table load limit must account for the weight of the rotary unit plus workpiece and fixture — lightweight rotary tables are preferred.
04
YCM provides a standard machine warranty that typically covers the spindle for 1–2 years against manufacturing defects. Spindle warranty terms vary by market and dealer — North American buyers should confirm the specific spindle warranty with their authorized YCM dealer at time of purchase. YCM's spindle repair and replacement service is available through the dealer network.
05
The YCM NV408A can perform hard milling operations in steel hardened to 55–60 HRC using carbide ball nose end mills at appropriate chip load and stepover. The machine's linear guideways and 12,000 RPM spindle are suited for light hard milling and finishing passes. For sustained heavy roughing of hardened material, a box-way machine provides better vibration damping — the NV408A is best positioned as the finishing machine in a hard milling workflow where a box-way machine handles rough material removal.
