Custom & Prototype Manufacturing
Contents
Sub-nanometer precision. 230+ materials.
Custom and prototype parts from a single piece.
TDC is a specialist manufacturer in ultra-precision polishing and machining.
We work at nano- to sub-nanometer precision levels, handling custom and prototype parts across a wide range of materials and specifications — including requirements that other suppliers have been unable to fulfill.

From Consultation to Prototyping and Material Sourcing
Specification Consultation
Even if your specifications aren’t fully defined yet, we’re ready to help.
Whether you need to confirm technical feasibility — such as achievable precision levels or material compatibility — or simply have a function or application in mind, we can propose the right machining conditions and materials for your needs.
Drawings are not required to get started.
Sample-First Production
Rather than going straight to full-scale production, you can also start with a small sample piece to verify precision and surface finish before moving forward.
We support this step-by-step approach for customers who want to confirm results at each stage.
Material Sourcing and Machining Under One Roof
At TDC, we can handle material procurement on your behalf, so you don’t have to manage multiple suppliers.
We also provide consultation on material selection. Feel free to contact us regarding any specialty or new materials you have in mind.

Precision Cleaning
In addition to ultra-precision polishing and machining, we offer precision cleaning in a cleanroom environment.
From machining to cleaning, everything can be handled here. Cleaning-only requests are also welcome.

Precision Measurement
We maintain a range of high-precision measurement instruments in-house, including the Bruker Dimension Icon (AFM), Taylor Hobson Talysurf and Talyrond, Hamamatsu Photonics Optical Nano Gauge, and Mitutoyo LEGEX9106.
Measurements are conducted in a temperature-controlled metrology room, and results are delivered with measurement data. Measurement-only requests are also welcome.

Surface and Sub-Surface Evaluation Using NanoTerasu
TDC utilizes NanoTerasu, a next-generation synchrotron radiation facility in Japan. Using synchrotron light one billion times brighter than sunlight, NanoTerasu enables visualization of crystal structures and chemical bonding states at the nanometer level, allowing analysis of surface and sub-surface conditions down to the atomic level.
Feel free to contact us regarding surface and sub-surface evaluation using NanoTerasu.
