The Process of CNC Machining
The rotating tool previously stated can move in relation to the component along the X, Y, and Z axes with a 3-axis machine (thus the name), but it is stuck in a vertical (or horizontal, depending on the machine) position. The tool can move simultaneously in any combination of the three axes with modern CNC mills.
The movements of a 5-axis machine are identical to those of a 3-axis machine, except they also include rotation about the X and Y axes. Despite the fact that both types of machines exist, the bed is often what rotates. With the additional rotation, each setup's machining may be done with much more freedom.
Advantages
1. Rapid and Reliable: Large volumes of metal can be quickly removed, and parts can be ready in just one day.
2. Scalable Volume: CNC Machining can produce 1-100,000 parts at scalable volumes.
3. Accuracy – Depending on customer specifications, high-precision tolerances range from +/-0.005′′ to 0.01′′.
4. Bespoke Surface Finishes—Suitable for a variety of substrate types, these finishes may make your parts look just like finished goods.
5. Vast Selection of Materials: Choose from more than 50 metal and plastic options.
6. Cost Savings: Economic for items with basic structures, low investment in tooling and preparation costs.
CNC Techniques
1. CNC milling - CNC milling is used to produce intricate 3D objects or to provide a machined surface finish to plastic or metal. We employ powerful programming software and 3, 4, and 5-axis CNC machining facilities with quick-change tooling.
2. CNC Turning: Metals and polymers can be turned at high speeds and with excellent quality using CNC lathes. Internal bores and complex exterior geometries can both be produced through turning. We have the turning capability to handle low-volume production all the way up to prototypes.
3. EDM (electric discharge machining) is a technique for creating holes, pockets, and other shapes in hardened steel. It can also be used to give mold tools' internal cavities a textured surface. It can cut through tool steels that have been hardened.
Available Materials
Metal: Aluminum 6061&7075&5052, Brass H59, Copper, Stainless Steel 304 &316&303, Iron, Titanium (Ti), etc;
Plastics: ABS, Polypropylene (PP), Polycarbonate (PC), Acrylic (PMMA), Nylon 12(PA12), Nylon 6/66(PA6/66), Delrin (POM), PET, PEEK, Polyurethane (PU), PVC, PPS, PVDF, etc;
CNC Applications
Prototypes--CNC machining allows for the creation of prototypes using identical material that will eventually be used in mass production. It is a suitable option for functional prototyping due to its high tolerance.
Mold Making—Using CNC, high-quality injection molding tools made of aluminum 7075-T6 can be produced, and tooling made of P20, NAK80, and H13 steel can be produced in quantities of up to 100,000 pieces.
Final Products---Before mass manufacturing, low-volume end products built using the precise material that will ultimately be produced can be developed using CNC machining. Certain straightforward parts can even be mass-produced.
Various Finishes
1. As machined
the completion alternative with the quickest turn-around.
There are obvious tool marks and maybe sharp edges and burrs left on the parts, but these can be removed upon request. Comparable to a 125 in Ra finish is the surface finish.
2. Sandblast
The process of violently projecting a stream of abrasive material on a surface under high pressure to smooth a rough surface, roughen a smooth surface, shape a surface, or remove surface contaminants is known as abrasive blasting, sometimes known as sandblasting.
3. Anodizing
The electrochemical process of anodizing transforms the metal surface into an attractive, long-lasting, corrosion-resistant anodic oxide finish. Although other nonferrous metals, such as magnesium and titanium, can also be anodized, aluminum is best suited for the process.
4. coated in powder
A form of coating called powder coating is applied as a dry, free-flowing powder. The fundamental distinction between a powder coating and a traditional liquid paint is that the powder coating does not need a solvent to keep the binder and filler components coated and is instead heated to cure it, causing it to flow and form a "skin." Thermoplastic or thermoset polymers could make up the powder. It is typically employed to produce a hard finish that is more durable than regular paint. Metals including household appliances, aluminum extrusions, drum hardware, and components for cars and bicycles are typically coated with powder.
5. Electroplating
