CNC machining is a rapid manufacturing process that turns digital 3D designs into plastic or metal parts by selectively cutting away material. Many companies require CNC machining services to make parts and prototypes, and many industries use versatile technology.
But CNC machining comes in various forms. Although all CNC machining technologies follow a similar workflow — software turns the digital design into machine instructions, which instruct the CNC machine to cut material — the hardware for cutting material can differ greatly between machines.
This article discusses the main differences between two of those machines: CNC mills and CNC turning (or lathes centers).
In the article we discuss the essential features of
CNC milling is one of the most common CNC machining services, and machinists can use it to make a wide variety of CNC machined parts. Prototype companies often use CNC mills to make one-off functional prototypes.
CNC mills use computer instructions to move a rapidly rotating cutting tool along three or more axes. When the spinning cutting tool makes contact with the workpiece, it removes material in a controlled manner. The cutting tool makes a succession of passes against the surface of the workpiece until the workpiece resembles the desired part.
The two methods of die casting are hot or cold chambered. The process that is used depends on the type of metal and the part. The cold chambered method is used with metals that have a high melting point such as alloys of aluminum, brass, or copper. Hot chambered die casting is limited to metals that won‘t dissolve when heated such as zinc, lead, and magnesium alloys.
The process of die casting is efficient, economical that offers a broad range of shapes and components. Parts produced have a long life and can be produced to be visually appealing giving designers significant advantages and benefits.
The high speed of die casting produces complex shapes with close tolerances requiring no after production processing. There is no need for additional tooling or shaping. Final parts are heat resistant with high tensile strength.
It’s been evident since the start of 2021 that construction, both commercial and residential, is exponentially expanding in our region – to our industry’s, and our economy’s, gain. However, this growth in construction has also created an adverse effect on one of the most important aspects that keeps the industry functioning smoothly: the construction supply chain.
As construction projects continue to rise, general contractors’ needs for
The cost of materials
According to Associated General Contractors (AGC), government data released earlier this month, another round of costly pricing increases and supply chain disruptions have perpetuated further hardships on contractors in our region, not only driving up construction costs, but also slowing down progress on their projects. In some cases, prices per unit almost doubled. Additionally, the data found that more than three-fourths of construction firms have indicated projects are being postponed or canceled due to unavailable materials or cost overruns, while only one out of five reported winning new work in the previous two months.
What is welding?
When did it first occur?
1800s: More than 2,000 years ago in the Bronze Age, small, gold circular boxes are made by pressure welding lap joints together. During the Iron Age, Egyptians and Eastern Mediterraneans learn to weld iron before the art of blacksmithing is developed during the Middle Ages.
During this time, gas, cutting, and resistance welding are developed. Nikolai Benardos and Stanislaus Olszewski secure a British patent in 1885 and an American patent in 1887 for welding. This was the beginning of carbon arc-welding with iron and lead.
