The diversity of CNC prototype model processing methods?

Do you know the CNC prototype model? The following Pingte precision hardware parts processors will explain to you!

With the gradual growth of the prototype industry, the manufacturing process has also been updated day by day. There are 3D printing and silica gel casting. But CNC machining is still the most common way to produce parts. At present, the common methods of CNC machining prototype models are as follows:

1.CNC turning

Turning simply involves clamping the workpiece firmly on a rotating plate or mandrel. When the workpiece rotates, the cutting tool is fixed against it in a fixing device mounted on the moving slide. The slider can move up and down along the length of the workpiece, and get closer to or away from the centerline. This simple operation is ideal for quickly removing large amounts of material. In addition, the drill installed on the tailstock of the lathe can drill precise holes; the lathe is used to form concentric shapes on the outer circumference of the circular part; the lathe is used to make grooves, ring grooves, step shoulders, internal and external threads, cylindrical Body and shaft-many round or round features.

2.CNC milling china

Milling is fundamentally different in that the workpiece remains stationary and the cutting tool rotates on the spindle. The workpiece is usually held horizontally in a machine vise and installed on a worktable that moves in the X and Y directions. The spindle can hold various tools and move on the X, Y and Z axes. Milling cutters are used to make squares/flats, notches, chamfers, channels, profiles, keyways and other features that depend on precise cutting angles. As with all metal processing operations, the cutting fluid is used to cool the workpiece and cutting tools, for lubrication, and to wash away metal particles or chips.

3. Grinding

Grinding to make a very flat surface on a metal part is important for many applications, and the best way to make such a precise surface is to use a grinder. The grinder is a rotating disc covered with abrasive grains with a specific roughness. The workpiece is installed on the worktable and moved back and forth laterally on the sliding table below the grinding wheel, or sometimes remains stable when the grinding wheel moves. Depending on the material being ground, different types of abrasives are used. The thermal and mechanical stresses of the grinding process can adversely affect the workpiece, so the tool speed and temperature must be carefully controlled.

4.EDM

Solid EDM is used to make pits, holes, and square features inside hardened tool steel. It is difficult, if not impossible, to make any other way. It is usually used in molds for plastic injection and pressure molding, and is rarely used in the finished part itself. EDM is also used to make textured surfaces or recessed (depressed) letters and logos on molds.

5. Wire cutting

Wire cutting uses copper wire as a conductor of high-voltage electrical charges. Since the conductor is steadily corroded during the cutting process, a new wire is supplied from the spool. This technique needs to be passed and cannot be used for blind holes. Wire cutting is used on thick, hardened tool steel to create round or semi-circular features, which would be very difficult to manufacture with conventional cutting tools.

6. Optical polishing

Optical grinding we only discuss processing metals, but CNC machining is also used to make special optics for glass or plastic. Optics require very fine surfaces with very tight tolerances, so special grinding equipment is used to rotate the grinding wheel relative to the surface when rotating on multiple axes.
