Experienced CNC Machine Shop in Santa Clara County

High-precision milling requires a high-precision machine shop in Santa Clara County. Since the advent of the CNC machine, it’s become an essential component in contract manufacturing. From two-dimensional design to three-dimensional fabrication, CNC machines handle every stage of production, eliminating human error from the machining process. Because production is so precise, the machine can replicate every component with absolute accuracy. Higher accuracy translates to higher quality.

Exacting Requirements

Typically, more volume in the manufacturing processes results in errors. However, a professional machine shop can reliably fabricate parts and pieces to such exacting specifications that errors are virtually impossible.

Save Time & Money

Time is money when it comes to labor costs. Because it can handle volume with precision, an experienced machine shop can increase your profit margin while ensuring the quality of the product remains high.

Industry Adaptability

High-precision milling is only increasing in demand. Not only are CNC machines incredibly accurate, but they are also highly adaptable. As markets fluctuate, technology advances, and specifications change, a CNC machine shop can adjust its fabrication techniques to meet industry demand.

There is no question that CNC machines changed the face of fabrication and production. From tabletop applications to 5-axis machining, when the question is how to mill your parts, there is only one answer.

The Evolution of the CNC Mill

Before the invention of CNC machining and mills, metalworking and fabrication was being done by numerical control (or NC) machines. The NC machines were invented in the late 1940s by John T. Parsons and the Massachusetts Institute of Technology (MIT). They had been commissioned by the United States Air Force, and the goal of their work was to find a more cost-effective way to manufacture aircraft parts with intricate geometries. NC became the industry standard.

The CNC mill was a possibility until the late 1960s when the concept of computer-controlled machining started to circulate. The early 1970s saw significant developments in CNC machining and the CNC mill. 1976 marked the first year 3D Computer-Aided Design/Computer-Aided Machining systems were made available. By 1989, CNC machines had become the industry standard.

The old NC machines had been controlled by punch cards that had a set of codes. These codes were called G-codes. The codes were made to give the machine its positioning instructions. A large sticking point with these machines was that they were hardwired, which made it impossible to change any pre-set parameters. As CNC machines and CNC mills became more prevalent and took over, G-codes continued to be used as a means of control, but now they were designed, controlled, and managed through computer systems. Today, the G-codes in CNC machines, along with logical commands, have been combined to form a new programming language. This language is called parametric programs, and the machines that feature it allow the worker to make real-time adjustments.
