Overview
The YCM SV108A is a large-table vertical machining center from Yeong Chin Machinery Industries (YCM), one of Taiwan's leading machine tool manufacturers and a consistent exhibitor at IMTS and EMO. The SV108A represents the larger end of YCM's SV series VMC lineup, featuring 1,080 mm of X-axis travel — a capacity that positions it for large prismatic workpieces, multi-fixture production setups, aerospace structural components, and large mold bases that smaller-table VMCs cannot accommodate.
YCM's SV series is constructed on a Meehanite cast iron base and column, with linear roller guideways on all three axes providing the combination of high rapid traverse speed and adequate rigidity for the medium-to-heavy cutting the SV108A's target customers perform. The column design is a fixed-column, moving-table arrangement standard to VMC architecture, with Y-axis travel at 600 mm providing a proportionally large working envelope. Z-axis travel reaches 600 mm, accommodating tall workpieces or tall fixture assemblies.
The spindle is a 10,000 RPM BT 50 unit powered by a 22 kW (30 hp) servo motor — the BT 50 taper reflecting the SV108A's orientation toward heavier cutting duties where the larger taper provides greater rigidity under high cutting forces. A 30-tool arm-type ATC serves the large-table machine, with tool-to-tool change time of approximately 2.5 seconds. The machine table measures 1,320 x 600 mm with T-slots, supporting workpiece loads up to 1,200 kg.
Control is Fanuc 0i-MF Plus as standard, with Mitsubishi M80 available as an option — both common in YCM's export deliveries to North America and Europe. YCM's reputation in the large-VMC segment rests on delivering Taiwanese-brand value (strong price-to-specification ratio) backed by a competent dealer network that includes North American and European distribution. Pricing for the SV108A typically ranges from $110,000 to $160,000 USD depending on options, significantly undercutting comparable Japanese or German machines at this travel class.

Strengths & Limitations
Strengths
- 1,080 mm X travel and 1,320 x 600 mm table open up a work envelope suitable for large mold bases, aerospace structural plates, and multi-fixture production setups that 500–760 mm VMCs cannot handle
- BT 50 taper spindle at 22 kW provides the torque and rigidity needed for heavy face milling, large-diameter boring, and deep-pocket roughing in steel and cast iron
- Taiwanese-brand pricing delivers the SV108A at $110,000–$160,000, substantially below comparable Mori Seiki, Makino, or Okuma machines at the same travel class
- 1,200 kg table load capacity supports heavy fixture assemblies and large aluminum or steel workpieces without requiring table load management
Limitations
- 10,000 RPM BT 50 spindle is appropriate for steel and cast iron but limits aluminum high-speed finishing where 15,000–20,000 RPM HSK spindles deliver significantly better surface finish and cycle time
- Machine weight of 10,500 kg demands a reinforced floor slab and rigorous site preparation — shops in older buildings must assess floor load capacity before purchase
- YCM's North American service network, while functional, is not as extensive as Haas's national coverage, meaning service response times vary significantly by region

Frequently Asked Questions
01
The SV108A is a large-table, BT 50 VMC designed for heavy cutting of large workpieces, with 1,080 mm X travel and 1,200 kg table capacity. The FX560A is a high-speed, BT 40 VMC designed for fast cycle times and precision finishing in smaller workpieces. They serve fundamentally different applications: the SV108A for large, heavy production and die-mold work; the FX560A for high-speed aluminum machining and precision medium-size parts.
02
Yes. The SV108A's Fanuc 0i-MF Plus control and large 1,320 mm table readily support 4th axis rotary table installations. YCM provides 4th axis prep packages that include the necessary wiring, control parameters, and table T-slot layout for standard rotary table mounting. The 1,200 kg table load capacity accommodates heavy rotary table and workpiece combinations, though total weight including the rotary unit and fixture must be checked against the capacity limit.
03
BT 50 is the appropriate choice for the SV108A's primary applications in large mold work and heavy aerospace structure machining. The larger BT 50 taper provides greater drawbar force, higher torque transmission, and better radial rigidity under the heavy cutting forces generated when face milling large steel plates or boring large-diameter holes. For shops doing primarily aluminum or light cutting, BT 40 at higher spindle speeds would be more versatile, but the SV108A is designed around BT 50 for good reason.
04
The YCM SV108A comes standard with a flood coolant system and spindle nose coolant nozzles. Through-spindle coolant at 40 or 70 bar is available as an option. For shops machining deep pockets in mold steel or performing deep drilling operations, through-spindle coolant is strongly recommended as it improves chip evacuation, extends tool life, and maintains dimensional accuracy by keeping the cutting zone cool.
05
YCM North America operates from a US headquarters and supports customers through an authorized dealer network covering major manufacturing regions. YCM provides direct applications engineering support, spare parts from US inventory, and field service technicians for major markets. Response times in less densely served regions can be longer — buyers outside major manufacturing corridors should confirm local dealer coverage before purchasing.
