CNC turning produces parts by "turning" rod material and feeding a cutting tool into the turning material. In CNC turning the cutter can be fed into the rotating workpiece at a variety of angles and many tool shapes can be used. CNC turning provides an economical way to make parts that are commonly symmetrical about an axis of rotation. Shapes that can be made using CNC turning include a variety of plain, taper, contour, fillet and radius profiles plus threaded surfaces. Although many turned parts use a single axis of revolution, there can be multiple axis to allow more flexibility (e.g. crankshafts). CNC turning can be combined with CNC milling and other processes to make more diverse shapes.
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. CNC 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. Additionally, the material can be turned to various orientations in the middle of the process and cutting tools of various shapes can be used. Material is usually removed by both the end and the side of the cutting tool.
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.
CNC Sheet metal stamping dies are used to produce high precision metal components which are identical in shape and size. The dimensional accuracy and stability which you can achieve using precision CNC metal stamping are very high and thus quality made metal stamping dies are critical.
You can see metal stamping components everywhere. From the electrical switches at your home to the computer casings, cars, aircrafts, everything that needs precision metal stamping parts. A highly specialized branch of mechanical engineering, metal stamping technology has grown considerably with the evolution of sophisticated machineries, CAD and CAM.
Sheetmetal stamping services: Modular stamping, Progressive die stamping, High-speed stamping, Deep draw stamping, Bore slide stamping, Transfer stamping.
CNC bending is a process where sheet metal is bent to an angle using, typically a V shaped punch or a die. The sheet is placed between the punch and die which presses down on the sheet. CNC bending provides a low cost method to produce 3D shapes from 2D sheets.
CNC bending is a suitable for processing most ductile metals and primarily for sheet metal designs with one or more bends. Just a few examples of CNC bending applications are brackets, enclosures, cams, chassis, etc. There is generally no special tooling required for CNC bending, with the exception of intricate designs and special bends.
