• Machine tool rotary tables • index tables • ideal gear system • High precision, high efficiency, high durability • Double worm gears that are high precision as well as high speed We have tried to make double lead worm gears to meet our customers'requests for high-speed rotary tables. However, we failed many times with the precision. Finally, we obtained cooperation from hobbing makers and many other companies to complete high-precision double lead worm gears.
