Machined Parts & Components

Machining is various processes in which a piece of raw material is cut into a desired final shape and size by a controlled material-removal process. It almost always implies the use of machine tools (including power tools and hand tools).

Machining is a part of the manufacture of many metal products, but it also be used on materials such as wood, plastic, ceramic, and composites. Our most machining is carried out by computer numerical control (CNC), in which computers are used to control the movement and operation of the mills, lathes, and other cutting machines.

Also we offer OEM/ODM machined parts. The machined parts including spare parts which Sino Machine Industry supplied were produced per customer’s drawings or specifications. All the parts are made in China. Chinese Castings Serving the Industrial Markets of the World.

Special material (titanium, copper, precision glass ) balls

Polishing stainless steel ball
Applied Area：Polishing stainless steel ball is generally used for polishing other hardware, to make the workpiece (copper piece, aluminium piece, silver piece) slippery and shining. In addition, steel ball can also rubbing medicinal materials and chemical materials.
Speciality： Any kind of steel ball can be used for polishing, but we should choose Material and size bases on the size, form and capability of the workpiece.
Flying saucer/Grinding ball
Applied Area：Flying saucer ball is mainly used for polishing all kinds of hardware, especially well for the workpiece in anomalous form.
Speciality：The material of flying saucer ball mostly is carbon steel, 201 stainless steel, 304 stainless steel, the size is ￠3.5×5.5, ￠4×6, ￠5×7, ￠7×10, we can offer more non-standards as you need.
（H62/65）Brass/copper ball
The brass ball we can offer is mainly 62%Cu and 38%Zn, it is used in switch. Brass ball is soft so it is easy to be drilled, it is also used in valve and craftworks.
High Precision Glass Ball
We mainly offer high precision glass balls of 1.5mm-8mm, we have bright glass ball and sand grinding glass ball, they are mainly used in sprayer, all kinds of scent bottle, pneumatic gun, decoration, they are colorless and transparent.
Titanium balls
Titanium balls are light weight (approximately 60% of the density of steel) that are nonmagnetic and offer good heat transfer properties. Titanium balls are an excellent choice for a variety of medical applications due to its general biological compatibility. The combination of high strength, stiffness, good toughness and low density make titanium an excellent choice for many aerospace applications. The excellent corrosion resistance and bio-compatibility coupled with good strengths make it very useful in chemical and petrochemical applications, marine environments and jewelry.
Hollow Stainless Steel Balls
The hollow stainless steel ball we can produce is widely used in craftworks, valve, architecture. We mainly produce 201 and 304 hollow stainless steel ball, you can order nonstandard ones.
