The CRYSTA-Apex S 9106 from Tokyo Seimitsu sits in a quiet measurement room, its granite table cold and smooth under the operator's hands while the bridge glides over a machined engine block with a soft, precise hum.

What the CRYSTA-Apex S 9106 is

The CRYSTA-Apex S 9106 is a CNC coordinate measuring machine in bridge design with a measuring range of 900 mm in X, 1000 mm in Y and 600 mm in Z, aimed at medium to large components in automotive and industrial production.

Tokyo Seimitsu markets the CRYSTA-Apex S family as its core bridge CMM line under the Accretech brand, providing high-accuracy tactile probing with automatic scanning routines for dimensional inspection of castings, gear housings and precision machined parts.

Measuring range and accuracy

With its 900×1000×600 mm volume, the CRYSTA-Apex S 9106 fits bulky cylinder heads, transmission casings and structural parts without forcing awkward setups or multi-stage repositioning that can add uncertainty.

The granite base and rigid bridge construction are designed to hold micrometer-level accuracy across the full travel, so operators can trust repeatable results even when parts sit on heavy fixtures or pallets.

Workflow on the shopfloor

In day-to-day use, a metrology engineer like Accretech application specialist Kenji Sato calls up a stored measurement program, clamps a slightly oily workpiece, and watches the probe trace edges and bores while the software paints live deviation colors on screen.

The tactile feedback is subtle: the probing head touches surfaces with a soft click, then the bridge accelerates and decelerates smoothly, keeping vibration low so measurements stay clean even close to tolerance limits.

Software and integration

The CRYSTA-Apex S 9106 is typically paired with Accretech's own CMM software, which supports CAD import, automatic feature recognition and auto-generated probe paths, reducing programming time for complex geometries.

Measurement results can be exported into common QDAS or CSV formats, allowing quality engineers to feed data straight into SPC dashboards and trace capability indices over long production runs without manual transcription.

Target customers and sectors

Tokyo Seimitsu is clearly targeting automotive tier suppliers, precision machinery builders and aerospace job shops that need one bridge CMM to cover both prototype inspection and serial sampling of heavy parts.

The 9106's footprint and travel make it more suitable for a dedicated measuring room than for a cramped machine-tool island, but the machine can be integrated into semi-automated cells with pallet systems if needed.

Price level and availability

Tokyo Seimitsu does not publish a list price for the CRYSTA-Apex S 9106, but CMMs in this size and class typically run into the low six-figure euro or yen equivalent range depending on probe system and software options.

The model is marketed globally under the Accretech umbrella, with sales and service hubs in Japan, Europe and other regions, and customers usually configure the system via local distributors or direct sales engineers.

Company context and shares

Tokyo Seimitsu complements its semiconductor manufacturing equipment business with metrology systems like the CRYSTA-Apex S line, giving the group exposure to both chip and precision-machining cycles. Tokyo Seimitsu shares (ISIN JP3571400005) trade on the Tokyo Stock Exchange in Japanese yen.
