How To Find Precision Prototype and Production CNC Machining

If you are looking for busbar bending machine in general, you are open to a variety of options. Many metal fabricators are offering prototype production by use of CNC machining which is a process of metal fabrication. Their precision in getting it done is what has amused most of their customers.

Metal fabrication is an art that involves the creation of metal structures or machines through the processes of cutting, bending and assembling. This involves a variety of raw materials which range from different kinds of metals depending on the final piece to be achieved. All these processes involve their own individual procedures before the structure can be properly built or assembled. Basically there are many standard raw materials that are used by metal fabricators. These include: plate metal, expanded metal e.g. square or tube stock, welding rods, castings, fittings and hardware.

Fabricating sheet metal to meet desired objects that meet the market needs requires the right tools and processes. One of such processes would be the CNC turning. This is a cutting process that involves production of parts by feeding a cutting tool to the turning material. In protocol & production CNC machining, the material to be cut is fitted on a lathe where it’s in constant rotation as a cutting tool is fed onto the rotating work piece. In producing various shapes, the cutter is fed onto the work piece in a variety of angles or axises.

Considering its ability to produce perfectly symmetrical objects under the axis of revolution, it is considered economical in the metal fabrication process. The turning costs can as well be optimized to make ensure a more economical working process. This can be made possible through:

  • reducing the complexity of the process,
  • minimizing on the materials being removed and
  • Avoiding complexity in the shapes being created. Long thin shapes for example would be very difficult to produce.

The process involves the turning of a couple of rigid materials like: aluminum, copper, stainless steel, nylon, steel, polycarbonate, acetyl, bronze, etc. All these materials are able to produce different shapes but with the varying difficulty levels due to their different densities. For Prototype & Production CNC Machining, some of the shapes that could be made are: taper, plain, fillet, contour and threaded surfaces plus radius profiles. To allow for more flexibility in the cutting process, the axis of revolution can be increased from one to multiple settings as in a camshafts. It is notable that with yet another combination of the CNC milling, this machining method is able to produce more diverse shapes.

CNC turning is known to produce the following common parts: shift knobs, robot parts, auto parts, pulleys, hubs, shafts, flywheels, motorcycle parts, toy parts, bushings, etc. In producing these parts, one has to be very considerate of the design process. Considering that the turning process applies a lot of pressure on the material, weak shapes that may involve flexing would be difficult to produce. For example this would be the case if long thin structures were used. The turning process generates a cut surface with helical marks resulting from the rotational feature as the cutter grinds on the material. With a specified surface roughness, the turning process is able to produce whatever marks you are particularly interested in. It is however worth noting that if the ratio of the diameter to the depth is high, bored holes become difficult.
