Steellong offers a variety of CNC milling parts and components to fulfill the requirements of a diverse customer base. From automotive and aerospace to electronics, our appropriate experience and service attitude can satisfy your needs.
CNC milling is a cutting process in which material is removed from a block by a rotating tool. In CNC milling the cutting tool is moved in all three dimensions to achieve the desired part shape. In CNC milling the cutting tool usually rotates about an axis that is perpendicular to the table that holds the material to be cut. A milling machine looks somewhat like a drill press at first glance. A cutting tool protrudes down from a rotating spindle. A block of material is placed on a moving table below the cutter. While the cutting tool turns, a computer controls the vertical (Z axis) motion of the cutter and the horizontal (X and Y axis) motion of the block of material. The cutter is guided to move through the material, removing portions to create shapes.
CNC Milling has several advantages over other manufacturing processes. It is cost effective for short runs. Complex shapes and high dimensional tolerances are possible. Smooth finishes can be achieved.
CNC milling can produce almost any 2D or 3D shape provided that the rotating cutting tools can reach the material to be removed. Examples of CNC milled parts include engine components, mold tooling, complex mechanisms, enclosures, etc.
CNC Milling can process most rigid materials including most metals: Aluminum, Stainless Steel, Copper, Steel, Brass, Titanium, Sterling Silver, Bronze, etc. And hard plastics and other materials: Nylon, Acetal, Polycarbonate, Polystyrene, Acrylic, Fiberglass, Carbon fiber, Teflon, ABS, PVC, etc.
Although tooling is mainly software, custom jig tooling is often required for workholding. Cost reduction options include reducing the amount of material removed, limiting complexity, avoiding intricate features and making shapes that are easy to hold.
We can supply you a wide range of stainless steel milled parts in diffrent shapes and styles.

Milling is the most common form of machining, a material removal process, which can create a variety of features on a part by cutting away the unwanted material. The milling process requires a milling machine, workpiece, fixture, and cutter. The workpiece is a piece of pre-shaped material that is secured to the fixture, which itself is attached to a platform inside the milling machine. The cutter is a cutting tool with sharp teeth that is also secured in the milling machine and rotates at high speeds. By feeding the workpiece into the rotating cutter, material is cut away from this workpiece in the form of small chips to create the desired shape.
Milling is typically used to produce parts that are not axially symmetric and have many features, such as holes, slots, pockets, and even three dimensional surface contours. Parts that are fabricated completely through milling often include components that are used in limited quantities, perhaps for prototypes, such as custom designed fasteners or brackets. Another application of milling is the fabrication of tooling for other processes. For example, three-dimensional molds are typically milled. Milling is also commonly used as a secondary process to add or refine features on parts that were manufactured using a different process. Due to the high tolerances and surface finishes that milling can offer, it is ideal for adding precision features to a part whose basic shape has already been formed.
