Accurate warp thread tension control across all beam winding speed modes in plant
Energy efficient drying cylinders with uniform steam distribution across the yarn
Automated dosing and continuous circulation of sizing liquor inside the main trough
Digital microprocessor system with color touch display for process setup and review

Engineering foundation and manufacturing capabilities of Tsudakoma rotary tables

Tsudakoma Corp. has developed high-precision machine tool attachments and NC rotary tables in Kanazawa, Japan, since 1909.

Built upon its proprietary foundry technology, precision machining centers, and strict geometric inspection protocols, the brand represents a global benchmark for accuracy in 4th and 5th axis CNC operations.

The structural foundation of every Tsudakoma table utilizes high tensile ductile iron housings, preloaded angular contact cross roller bearings, and heavy duty hydraulic disc clamping mechanisms.

This rigid design minimizes vibration during aggressive milling and ensures long term geometric positioning repeatability.

Kinematics and backlash adjustment of Dual Lead worm gearing

The proprietary Tsudakoma Dual Lead worm gearing system features differing leads on the right and left tooth flanks.

As the worm rotates, the tooth thickness changes continuously along the shaft axis, allowing backlash elimination through simple axial adjustment of the worm shaft without altering the gear center distance.

The worm wheel is manufactured from an aluminum bronze alloy designed for high wear endurance, while the worm shaft is machined from carburized alloy steel with ground tooth flanks.

This kinematic pairing delivers high mechanical efficiency, minimal heat generation during continuous indexing, and easy maintenance.

Positioning accuracy standards and high-resolution optical encoders

Every Tsudakoma rotary table and indexing device undergoes factory calibration using precision laser interferometers and optical polygon mirrors.

Positioning and repeatability tolerances satisfy ISO 230-2 and Japanese Industrial Standard JIS B6330 benchmarks with angular errors limited to only a few arcseconds.

For high precision five-axis models in the THNC and TN lines, integrated Heidenhain circular optical encoders are mounted directly on the rotary spindle.

Direct angular measurement eliminates drive train gear error and ensures supreme contouring accuracy during complex 5-axis simultaneous blade and mold profiling.

Selecting replacement components and assemblies by equipment nameplate

We identify and supply components for the entire Tsudakoma machine tool line: Dual Lead worm pairs, spindles, bearings, brake friction discs, hydraulic seals, clamp cylinders, and servo motors.

Providing a photograph of the table nameplate or machine specification sheet enables prompt part identification.

Using the serial number and model designation, our technical team confirms the gear ratio, motor mount configuration, and CNC control interface.

We prepare transparent quotation documentation with international logistics support, export compliance, and direct delivery to manufacturing plants worldwide.

Textile machinery: high-speed air-jet looms and warp sizing systems

Tsudakoma represents a global leader in high-speed weaving technology, building on the legacy of its historic K loom.

Modern ZAX9200i and ZAX001Neo jet looms feature automated weft insertion systems, energy-efficient solenoid valve manifolds, and digital warp tension controls for continuous high-speed production.

Complementing the weaving looms, Tsudakoma supplies high-efficiency warp sizing machines, warping creels, and drawing-in units. Automated moisture, temperature, and liquor application controls ensure uniform yarn sizing, reducing thread breakage and maximizing overall weaving plant efficiency.

Industrial integration and multi-axis machining applications

Tsudakoma rotary tables and precision vises operate across aerospace manufacturing, power generation, automotive tooling, and high-precision instrument workshops.

Integrating 4th and 5th axis tables onto horizontal and vertical machining centers expands capabilities from standard prismatic milling to continuous multi-axis profiling.

Integration into machine control systems covers motor brackets, custom cabling harnesses, pneumatic or hydraulic booster units, and interface integration for Fanuc, Heidenhain, Siemens, Mitsubishi, and Brother CNC controllers. We support complete table installations and maintenance overhauls.
