Overview

The Yasda YBM 10T-TH is the largest vertical machining center in Yasda's ultra-precision lineup, designed for shops that need to machine large mold bases and die components without sacrificing the micron-level accuracy that defines the Yasda brand. With 1,000 x 750 x 500 mm (39.4 x 29.5 x 19.7 in) X/Y/Z travel, it handles substantial workpieces — think full-size bumper molds, large progressive die sections, and aerospace structural components — with the same hand-scraped precision that the smaller YBM models deliver.

The 'TH' designation indicates the thermo-symmetric headstock design, which is a critical engineering feature for a machine of this size. As large castings absorb and release heat during extended machining cycles, the thermally balanced head ensures that spindle centerline position remains stable regardless of ambient temperature changes or heat generated by the spindle motor. Combined with Yasda's multi-sensor thermal compensation system, the YBM 10T-TH maintains +/-2.0 micron positioning accuracy even during 20-hour unattended finishing cycles on hardened steel.

Like all Yasda machines, the 10T-TH features hand-scraped box guideways on all three linear axes. The massive Meehanite cast iron base and column are stress-relieved and aged before precision scraping, creating a structural foundation that resists deflection under heavy cutting loads. The BT50 spindle provides 22 kW (30 HP) of continuous power at speeds up to 12,000 rpm, with optional 15,000 rpm for shops needing higher surface speeds for finish machining. The table accommodates workpieces up to 2,000 kg (4,409 lb).

The 10T-TH fills a critical gap in the market: large-envelope vertical machining with genuine precision-class accuracy. Most large VMCs sacrifice accuracy for envelope, forcing shops to rough on the big machine and finish on a smaller precision VMC. The Yasda 10T-TH eliminates that compromise, delivering one-setup accuracy on large parts that would otherwise require multiple machines. The Fanuc 31i-B control is standard, with Heidenhain TNC 640 available as an option.

Strengths & Limitations

Strengths

Largest Yasda VMC envelope at 1,000 x 750 x 500 mm delivers precision-class accuracy on full-size mold bases and large die components
Thermo-symmetric headstock design maintains spindle centerline stability during extended machining cycles regardless of temperature changes
Hand-scraped box guideways provide vibration damping and geometric stability essential for finishing hardened steel mold surfaces
2,000 kg table capacity handles heavy mold bases and die blocks without auxiliary support
Multi-sensor thermal compensation system actively corrects for thermal growth during lights-out operation
Eliminates the need to rough on a large VMC and finish on a smaller precision machine — one-setup accuracy on large parts

Limitations

Premium pricing of $500K-$700K reflects the hand-built precision construction but requires significant capital justification
15,000 kg machine weight requires reinforced flooring and careful foundation preparation
12,000 rpm standard spindle is adequate but slower than the 15,000-20,000 rpm common on smaller precision VMCs
Lead times of 8-12 months are typical due to the extensive hand-scraping and assembly process
Box guideway rapid traverse of 30 m/min adds cycle time compared to linear guide machines on parts with extensive repositioning

Best For

Mold shops machining large bumper molds, dashboard molds, and other full-size injection mold bases requiring precision finishing Progressive die manufacturers needing micron-level accuracy across large die plates Aerospace structural component manufacturers machining large aluminum and titanium parts with tight tolerances Shops wanting to eliminate the two-machine workflow of roughing on a large VMC and finishing on a precision VMC Large mold base finishing operations where thermal stability over 16-20 hour cycles is critical for dimensional accuracy Any application requiring +/-2.0 um accuracy on workpieces up to 1,000 mm in X-travel

Frequently Asked Questions

01 What does a Yasda YBM 10T-TH cost?

New YBM 10T-TH machines typically price between $500,000 and $700,000 depending on spindle option, control choice, and tooling configuration. These machines rarely appear on the used market, but when they do, expect $350,000-$500,000.

02 What does the TH designation mean?

TH stands for thermo-symmetric headstock. This design ensures the headstock construction is thermally balanced so that heat from the spindle motor and bearings expands symmetrically, keeping the spindle centerline position stable during extended machining cycles.

03 Can the 10T-TH handle heavy roughing on large mold bases?

Yes. The BT50 spindle with 22 kW continuous power and the massive 15,000 kg machine structure provide excellent rigidity for roughing. However, most shops buy the 10T-TH for its finishing accuracy and use a separate roughing machine for heavy stock removal to maximize the Yasda's availability for precision work.

04 How does the 10T-TH compare to a large Makino or Okuma VMC?

Large Makino and Okuma VMCs typically use linear guides and prioritize faster cycle times. The Yasda 10T-TH with hand-scraped box guideways and thermo-symmetric head is purpose-built for accuracy at the expense of speed. For shops where accuracy is non-negotiable, the Yasda is the better choice.

05 What foundation requirements does the 10T-TH have?

At 15,000 kg, the 10T-TH requires a reinforced concrete foundation typically 300-500 mm thick with proper isolation from shop floor vibrations. Yasda provides detailed foundation drawings during the pre-installation planning phase.
