Overview

The Yasda YBM 7Ti is a precision horizontal machining center built for shops that refuse to compromise on accuracy even in a production HMC format. Where most horizontals prioritize chip evacuation and cycle time, Yasda engineered the 7Ti to deliver jig-borer-class precision in a pallet-change horizontal configuration. With 700 x 700 x 600 mm (27.6 x 27.6 x 23.6 in) X/Y/Z travel and a 500 mm (19.7 in) pallet, it handles medium-sized production workpieces with the kind of accuracy that would typically require a dedicated vertical precision machine.

The foundation is Yasda's signature hand-scraped box guideways on all linear axes. Every sliding surface is hand-fitted during assembly at Yasda's Okayama factory, creating geometrically precise bearing surfaces that dampen vibration far better than linear guide systems. The BT50 spindle delivers 15,000 rpm with a direct-drive motor, producing 37 kW (50 HP) of continuous power for aggressive material removal in steel, cast iron, and aluminum. Through-spindle coolant at 70 bar is standard.

The 7Ti features a 2-pallet changer as standard, enabling setup on one pallet while the machine cuts on the other. The 60-tool ATC (90 optional) ensures complex multi-operation parts can be completed in a single setup. Positioning accuracy is +/-2.0 microns with repeatability of +/-1.0 microns — numbers verified under loaded cutting conditions. Yasda's thermal compensation system uses strategically placed sensors throughout the casting structure to correct for thermal growth in real time.

For shops running lights-out production of precision components — connector molds, optical lens molds, aerospace housings, medical implant tooling — the YBM 7Ti delivers the accuracy of a Yasda vertical in a horizontal format that naturally clears chips and supports automation. The Fanuc 31i-B control provides full 4-axis simultaneous capability through the B-axis rotary table. Competing machines include the Mitsui Seiki HU50A and Makino a61nx, though the Yasda commands a premium for its hand-scraped construction.

Strengths & Limitations

Strengths

Hand-scraped box guideways deliver vibration damping and geometric stability unmatched by linear guide horizontal machining centers
Jig-borer-class accuracy of +/-2.0 um positioning in a production HMC format enables precision work with pallet automation
BT50 direct-drive spindle with 37 kW provides both the rigidity for heavy cutting and the speed for finish machining
2-pallet changer standard enables continuous production with setup occurring offline for maximum spindle utilization
Thermal compensation with embedded sensors maintains accuracy during extended unattended production runs
Horizontal configuration naturally clears chips from the work zone, critical for deep pocket and cavity machining

Limitations

Premium pricing of $450K-$650K is significantly higher than mainstream production HMCs from Mazak or Okuma
Lead times can stretch to 9-12 months due to hand-scraping and limited production at the Okayama factory
500 mm pallet size limits the machine to medium-sized workpieces; larger parts require the YBM 10T series
North American dealer and service coverage is thin compared to major Japanese HMC brands
Box guideways limit rapid speeds compared to linear guide competitors, adding seconds to tool-change-heavy cycle times

Best For

Mold shops needing horizontal machining center accuracy for cavity blocks, core plates, and insert finishing Aerospace production cells requiring tight-tolerance machining of aluminum and titanium housings with pallet automation Medical device manufacturers producing precision implant molds and surgical instrument tooling Connector and electronics mold shops where sub-micron repeatability drives product quality Any production environment where accuracy must be maintained across thousands of parts in lights-out operation Shops looking to consolidate jig boring and horizontal milling operations onto a single high-accuracy platform

Frequently Asked Questions

01 What does a Yasda YBM 7Ti cost?

New YBM 7Ti machines price between $450,000 and $650,000 depending on tooling capacity, spindle options, and automation. Used machines rarely appear on the market; when they do, expect $300,000-$450,000 depending on age and condition.

02 How does the YBM 7Ti compare to the Mitsui Seiki HU50A?

Both are ultra-precision HMCs targeting the same market. The Yasda YBM 7Ti features hand-scraped box guideways for maximum damping, while Mitsui Seiki uses precision-ground guideways. Both deliver sub-5-micron accuracy. The choice often comes down to regional support and specific application requirements.

03 Can the YBM 7Ti run unattended production?

Yes. The 2-pallet changer, 60-tool ATC, through-spindle coolant, and thermal compensation system are all designed for lights-out production. Many shops run the 7Ti on 16-20 hour unattended cycles for mold component finishing.

04 What spindle taper options are available?

The standard configuration uses BT50 taper. HSK-A100 is available as an option for shops preferring the dual-contact HSK interface for higher-speed applications.

05 Is the YBM 7Ti suitable for heavy roughing?

Yes. The BT50 spindle with 37 kW continuous power and hand-scraped box guideways handle aggressive roughing in steel and cast iron. However, most shops buy the 7Ti primarily for its finishing accuracy rather than raw metal removal rate.
