The Top 3 Reasons:

See why our customers love us

I took a risk using TDB, as I hadn’t used them before. I sent them some very challenging, high-tolerance, CNC machined parts (some with machining from six sides), with some really small details.
We were blown away by the quality and accuracy of the parts. Bob Chan was quick to respond to my emails, well into the night, and we received the parts back in a short timeframe. We really couldn’t have been happier with the service. I would gladly recommend them to anyone.

We have been ordering CNC parts from TDB for over 5 years. Their quality and services are way better than what we can get from the other Vietnamese CNC machine shops. We always receive a fast quotation after we send through RFQs. Normally, within 12 hours or shorter which helps a lot. The projects we receive from TDB, both materials and geometry are always 100% matched every time. We are more than happy to stick to their services in long term.

We came across TDB when the first time we try to outsource CNC machining parts from Vietnam. They came back with a price, lead time, and suggestions in 5 hours. Seriously, I was shocked by their fast reaction and professional idea to improve the design. First-order was running super smoothly. We have been working with them for a lot of projects now. Their quality is always as expected or even better, and they deliver every project on the dot as well as good communication. I won’t hesitate to recommend TDB to any of my friends if they need CNC parts.

CNC Finishes

Enhance the functionality and appearance of your CNC parts with TDB’s surface finishing options.

  • As-Machined: The most popular and cost-efficient option for inner functional components. Fine and even tool path is also suitable for aspect parts.
  • Bead Blasted: A matt appearance is achieved by using a range of 120 to 320 beads to create different roughness on the surface.
  • Anodized: Type II creates a corrosion-resistant finish. Parts can be anodized in different colors, clear, black, red and blue are most common. Type III is thicker and creates a wear-resistant layer in addition to the corrosion resistance seen with Type II.
  • Powder Coat: A strong, wear- and corrosion-resistant layer is created by spraying powdered paint onto the part, which is then baked in an oven. A wide variety of colors are available to create the desired aesthetic.

Typical CNC Machnining Parts That We Offer

We machine custom parts for customers in multiple plastic and metal materials, from rapid prototypes,
low-volume production to mass production orders.

Overview: What’s CNC Machining?

What is CNC machining?
CNC machining is a manufacturing technique for removing material. It uses sharp cutting tools, available in a variety of shapes and sizes, which are precisely controlled by a computer. CNC stands for Computer Numerical Control.

How CNC machining works?
CNC machining starts with a computer, on which designers prepare a part using CAD (Computer-aided Design) software. This digital part is then converted into a format that can be recognized by a CNC machine.

Instructions are sent to the CNC machine in the form of “G-Code” after which the machine can start cutting.

Most CNC machines have a “worktable” and work holding device to keep a block of material — known as the “workpiece” — in place. The worktable may or may not move, depending on the style of the machine.

When machining starts, the cutting tool makes contact with the workpiece, cutting away layers of material. The tool and/or workpiece is moved and/or rapidly rotated according to the G-Code instructions so that cuts are made in exactly the right places until the part is finished.

Different types of CNC machine?
CNC machines include CNC mills, CNC turning machines (or lathes), CNC routers, and Electrical Discharge Machining (EDM) machines.

CNC mills have rotating cutting tools that are moved to different areas of the workpiece to make cuts and can be used to make many different pats. CNC lathes work the other way, rotating the workpiece against a stationary cutting tool, and are used to make cylindrical parts.

CNC routers are similar to CNC mills, but have less power and cannot cut the hardest materials. They can, however, be faster than CNC mills.

EDM uses electrical discharges (sparks) instead of a sharp cutting tool to cut material. No physical contact is made between the tool and the workpiece.

CNC machines are often defined by their number of axes. More axes mean they can move their tool and/or workpiece in a greater number of ways, giving greater cutting flexibility and the ability to make more complex parts in a shorter time.

CNC Machining FAQ

Choosing a higher tolerance than required isn’t a good idea when designing parts. If +/-0.05mm is sufficient, then going for +/-0.01mm will increase the production cost. However, CNC machining provides unrivaled accuracy and consistency when tolerances as fine as 0.01mm are required.

A wide range of materials can be used with CNC machining, including metal, copper, brass, zinc, magnesium, bronze, titanium, steel, and other plastics like PEEK, ABS, PC, PMMA, Teflon, and PPS.

We use CNC tools and technologies to guarantee tight tolerances in our machining processes. Our multi-axis CNC machines are equipped with CNC milling & turning precision grinding and EDM machines to ensure tight tolerances. Additionally, we employ experienced and skilled CNC engineers and operators to oversee quality control and production.

High-precision products require intricate design and extremely precise manufacturing processes. Manufactured products such as defense, healthcare, electronics, sports, aerospace, agriculture, and automotive are some of the products that require high-precision CNC manufacturing.

Software is a critical part of the CNC machine process, and there are several types of software you’ll need for a CNC machine. For example, CAD/CAM, Aspire, Inkscape, Easel, Fusion 360, SolidWorks, etc.
