Yumoto Vietnam
Discover real examples of precision CNC machining by Yumoto Vietnam. From Hastelloy and HPM75 to Aluminum and plastic material such as Bakelite and MC Nylon, our skilled engineers achieve tight tolerances and high quality products. We support heat treatment, grinding, anodizing and various other types of surface treatments for prototypes and small-lot production.

Material: Hastelloy
Required tolerance: 0~+0.05
Quantity: 50 units
Hastelloy is a difficult material which hardens while machining. Moreover, the top surface has a thickness of only 0.5 mm so we were careful of the processing steps in order to not rupture the surface.
Material: HPM75
Required tolerance: 0.02 mm
Quantity: 2 units
HPM75 is a very hard material (HRC41~44), and it even hardens while machining. Processing can be difficult as material can be easily chipped.

Material: SUS304
Required tolerance: 0~+0.05 mm
Quantity:1 unit
To achieve the required tolerance, set-up steps were planned carefully to avoid any deviations. This product was produced as part of prototype of Overlord's Model 1 coffee grinding machine. See more details of this prototype project here.

Material: A6061
Required tolerance: ±0.05 mm
Quantity: 2 units
This product has many thin grooves of thickness 1.5 mm. As the grooves are very thin and long, they can easily vibrate while machining. To avoid defective products, our skilled CNC engineers selected the proper tools, processing steps, and processing speed.

Material: MC Nylon (Blue)
Required tolerance: medium tolerance according to JIS B 0405
Quantity: 2 units
The end has a small thread of M8.
Material: SKH51 (YXM1)
Required tolerance: +/-0.01 mm
Quantity: 1 unit
The product undergoes several precision processes. After CNC machining, it is vacuum heat-treated to achieve a hardness of HRC 61–64. Next, the dimensions are fine-tuned through precision grinding to meet the required tolerance of ± 0.01 mm. Finally, the surface is coated with a protective layer of titanium nitride (TiN) to enhance durability and wear resistance.
Material: SCM415
Required tolerance: 0~+0.013 H6
Quantity: 28 units
This product was carburized heat treated to hardness of HRC50~55.

Material: SUS303
Required tolerance: ±0.05mm
Quantity: 64 units
The square hole on the side was processed with our EDM wire cutting machine.
Material: S45C-H (Thermal Refined Steel)
Required tolerance: +0.05/+0.23
Quantity: 42 units
This product requires induction heating of HRC37~43 just at one of the ends of the product, and then we do black oxide coating.

Material: Bakelite
Required tolerance: medium tolerance according to JIS B 0405
Quantity: 1 unit
This product is made from paper-based Bakelite material. It is a highly brittle material that chips easily, so special attention is required to do this intricate design.
Material: A5052
Required tolerance: medium tolerance according to JIS B 0405
Quantity: 1 unit
We did sand-blasting and orange anodizing for this product. We can support a variety of other types of color anodizing as well, including blue, red, green, purple, and black colors.
Material: SS400
Required tolerance: H8
Quantity: 32 units
The main difficulty with this product is drilling a 15 mm diameter hole with an H8 tolerance horizontally through the part.
