Technology / Expertise
ATI has the word-class high precision apparatus and equipment for precision metal alloy manufacturing. We use cutting machines such as Japan MAKINO CNC Machine Centers, Swiss CHARMILLES CNC Wire Cutting and EDM machines, etc. We use state of the art precision measuring machines such as MITUTOYO CNC 3D CMM, and various MITUTOYO precision measuring machines. With advanced technology of cutting, milling, grinding, precision turning, stamping and polishing, ATI also dedicates in providing super-thin permanent magnets.The thickness tolerances can be as precise as 5 microns.
Our milling machines may be operated manually or under computer numerical control (CNC), and can perform a vast number of complex operations, such as slot cutting, drilling and threading, rabbeting, routing, etc. The milling technology can produce most parts in 3D, but some require the objects to be rotated around the x, y, or z coordinate axis (depending on the need). Tolerances are usually in the thousandths of an inch (Unit known as Thou), depending on the specific machine.
Our Grinding technology uses an abrasive process to remove material from the work piece. Our state-of-the –art grinding machines are used for producing very fine finishes, making very light cuts, or high precision forms using an abrasive wheel as the cutting device. This wheel can be made up of various sizes and types of stones, diamonds or inorganic materials, depending on our customer’s needs to produce the required finish. Our technology has advanced grinding operations to include CNC controls and high material removal rates with high precision, lending itself well to aerospace applications and high volume production runs of precision components.
Our Cutting process may be accomplished by single-point or multipoint tools. Single-point tools are used in turning, shaping, plaining and similar operations, and remove material by means of one cutting edge. Milling and drilling tools are often multipoint tools. Grinding tools could also be used as multipoint tools. Each grain of abrasive functions as a microscopic single-point cutting edge, and shears any tiny chip.
Polishing is usually a multistage process, where our automated specialized equipments are use. The first stage starts with a rough abrasive and each subsequent stage uses a finer abrasive until the desired finish is achieved. The rough pass removes surface defects like pits, nicks, lines and scratches. The finer abrasives leave very thin lines that are not visible to the naked eye. Lubricants like wax and kerosene may be used as lubricating and cooling media during these operations, although some polishing materials are specifically designed to be used “dry.”
Our Stamping equipment includes performing a variety of sheet-metal forming manufacturing processes, such as punching using a machine press or stamping press, blanking, embossing, bending, flanging, and coining. This could be a single stage operation where every stroke of the press produce the desired form on the sheet metal part, or could occur through a series of stages. The process is usually carried out on sheet metal, but can also be used on other materials, such as polystyrene.
Basing on the type of product, our turning process can be either be done manually, in a traditional form of lathe (which frequently requires continuous supervision by the operator) or by using a computer controlled and automated lathe, better known as CNC). Our CNC is commonly used with many other types of machine tool besides the lathe.
The turning processes that we use are typically carried out on a lathe, and can be of four different types such as straight turning, taper turning, profiling or external grooving. Those types of turning processes can produce various shapes of materials such as straight, conical, curved, or grooved work piece.
