Gentle microfabrication for the human body

As emerging countries develop and aging populations grow in developed nations, the need for continuous medical care is increasing. To meet this demand, medical technology continues to evolve—requiring ultra-precise instruments. TNK’s advanced processing technology, capable of micromachining difficult-to-cut materials, provides solutions for these high-performance medical applications.

Medical/Healthcare Processing Technology

1. Microfabrication technology

Medical components often require ultra-fine, high-precision machining to access minute areas within the human body.
Upon request, TNK offers taper processing, pointed machining for small-diameter parts, and micro-hole drilling with a minimum diameter of φ0.04 including diagonal, though, and blind holes.(diagonal holes, through holes, blind holes, etc.) are possible.
TNK offers a wide range of microfabrication solutions tailored to your specific applications and requirements.

2. Assembly and welding technology

TNK has introduced a fiber laser welding machine to enable high-precision welding of miniature components.
TNK's advanced fabrication capabilities enable the production of elongated parts, non-standard profiles, and intricate shapes that exceed the limitations of conventional integrated processing systems. This can be achieved by combining multiple components through micro welding.

3.TNK sliding screw

This is a set product consisting of a metal screw and a plastic nut.
Screw sizes starting from φ0.55 mm are available, contributing to the miniaturization of units.
In addition, TNK's unique molding technology allowsAchieves minimal backlash of 2 µm or less, smooth sliding performance, and high durability through the use of specialized materials.This contributes to delivering precise control, silent performance, and long-lasting reliability for your unit.

TNK's products are widely used in actuators for precise robot control, joint units, and pumps requiring accurate flow rate adjustment.

4. Environment

TNK has installed a Class III clean room for medical applications, enabling processing and assembly operations that require strict cleanliness control.
We have also acquired ISO13485* certification, a medical device quality management standard, and have created a perfect environment to meet the demands of medical-related parts processing.
