Mech robot
Due to the ongoing labor shortage, workplaces are shifting from human-only tasks to teamwork between people and robots. TNK’s high-precision machining helps make robot parts smaller and more refined, improving robot performance and supporting miniaturization.
Making robots more approachable and safer
To ensure robots are safe and secure, both software and hardware play a critical role. With TNK sliding screws for high-precision positioning, along with a range of precision rollers and needles, TNK help deliver more accurate, refined, and smoother motion control.
Examples of robot parts
1.TNK sliding screw
This is a set product consisting of a metal screw and a plastic nut.
By designing and manufacturing each part in-house, we achieve highly accurate matching technology that enables ultra-smooth sliding with minimal backlash of just 2µm, along with excellent durability. This combination results in a quieter, more durable, and compact unit.
*Screw size from φ0.55
2.High-precision rollers and needles
These components are used in reducers and linear motion mechanisms
To achieve smooth motion without waviness, outer diameter tolerances often need to be in the sub-micron range—such as XNUMX/XNUMX of a millimeter.
There is no such JIS standardTNK offer ultra-high precision manufacturing with tailor-made shapes and sizes—designed to match your exact specifications.
Rollers and needles are generally offered in multiple ranks, but with TNK’s advanced grinding technology, we produce components to precise specifications, removing the need for classification and minimizing unnecessary stock for our customer.
TNK also handle small-lot production that is difficult for major manufacturers to handle.
3. Linear shaft
Taking advantage of our strength in centerless processing technology, Leveraging our expertise in centerless processing technology, TNK achieve world-class outer diameter tolerance and roundness. This shaft enhances the performance of linear reciprocating mechanisms by improving motion accuracy and stability.
Shaft end faces can be customized as F-face, R-face, or T-face, and are also available with holes, stepped profiles, and other specialized geometries.
TNK accommodates customer requests for a wide range of materials, including stainless steel, composite materials, and resin.
