Innovative dual lead worm drive
High torqueeHigh accuracy superior performance.

High-precision CNC worm grinding machine equipment

  • Innovating econtinuing research and development eincreasing equipmentdTANSHING has invested heavily in "high-precision CNC worm-gear grinding machine in order to fully control the parts' accuracy and insist on highest quality. It is always looking to the future, to new challenges and to new levels of high technology

Dual Lead Worm Drive (wheel & gear) Features and Benets

  • The worm-wheel made in special material aluminum bronze, containing Sn, Zn, Pb, Fe, Ni, Al, P, Mn, Aa, Cu.... as above 10 kinds of composite.
  • The material of worm-wheel has high anti-tensile, anti-pressure, Anti-oxidant, high toughness, Abrasion, Tensile strength of 650N/mm2 more, Elongation of 15% or less. Hardness at HB180 more. Wear consumption : 26.3mg/cm2 per 10000m
  • Developing "Indexable dual lead worm" with deeper teeth contact, larger contact area, bearing Large thrust, increase the rigidity and lower wear & tear for worm-wheel.
  • Worm machining equipments are replaced & purchased continually in order to ensure high precision accuracy of parts and shipment immediately. In general, the life will be 10~15 years when necessity to adjust accuracy.
  • Backlash adjustment

    Due to thread of "high teeth dual lead worm" is designed from small to Large pitch, there will cause backlash between worm-wheel & gear after long-term use. By shifting the worm longitudinally, the highest indexing accuracy is maintained on work table. Patent number 098,511.

  • Full circular hydraulic clamping system

    The wholly circular hydraulic locking system employs a clamping sleeve to lock the entire disc by hydraulic pressure. Because the locking position covers the entire disc circumference, a higher locking force than those of conventional pneumatic disc locking system also avoids disc surface deformation without aecting accuracy.

  • Advantages of quality inspection

    • TANSHING has invested heavily in high-precision on specting equipment, now owns CMMs, Laser Interferometers and has established a complete quality inspection processes.
    • Expanding inspection personnel to integrate quality systems, the checklist each assembly process details are listed. All products are controlled strictly by senior sta before delivery.
  • Product outline coating quality &
    waterproof advantage

    • TANSHING product waterproof is same design as Japanese brand. The standard machines are designed to the positive pressure drainage function connector, waterproof grade up to be IP66 (without the positive pressure drainage function, waterproof is up to IP65).
    • Painting dominant process is like European cars, ne quality process from manual surface treatment, high-pressure hot water cleaning> Putty> primer paint> high hardness, scratch-resistant topcoat.
  • CMM

  • Positive pressure drainage function connector

  • Laser Interferometer

  • high-pressure hot water cleaning

Product advantage

  • TANSHING select suitable models depending on machining conditions, the type of high load, high rigidity, high speed, high-precision, high-life type, zero backlash type, and ultra-high load of 20 to 60-ton large rotary table, hydrostatic rotary table, acceptable custom's design, another variety of new ve-axis rotary table & swing table …etc for completing series in our products lines.
  • We developed several new products recently such as: direct-drive DD torque motor Rotary table series, Hypoid Gear rotary table series, hydrostatic rotary table, etc..
  • Our R & D personnel quality and experience are the highest in the same industry, the development of new products is designed using 3D software with latest version, any customized accessories can be quickly planned & designed quickly.
