Customers looking for machine shops to help with their manufacturing project will frequently come across similar-sounding terminologies like “precision machining,” “high precision,” and “ultra-high precision” without any elaborate distinction on what these terms represent or what qualifies a machining company to execute a high precision work.

In manufacturing, “high precision machining” refers to milling components with tolerances in the single-digit micron range, and “ultra-high precision machining” entails tolerances in the sub-micron region. Machining components with extremely tight tolerances is always a challenge, but the difficulty of machining is dictated not only by the tolerances required but also by the materials used and the number of features on the part.

Ultra-high precision machining is also known as Swiss Machining. Swiss machining is a form of machining that originated in Switzerland during the 1800s. It began in the watchmaking business since specialized machining was necessary for a large number of tiny screws, pins, and other microscopic parts for the watch business.

Conventional lathes, in general, keep the component in a fixed headstock while the tools travel to it. In comparison, a collet in the main spindle of a Swiss machine holds the component as it goes back and forth. The true art of Swiss Machining is the combination of computer-controlled design and human engineering technique, which can produce unique functions and highly controlled output.

Machines and the process of Machining

Precision machining requires well-trained specialists to prepare files with extremely accurate parameters due to the nature of the process. To get the highest precision machining outcomes, it is necessary to precisely follow specified designs developed using computer-aided design (CAD) or computer-aided manufacturing (CAM) methods. The 3D drawings required to make parts are created using CAD or CAM files. These CAD or CAM files are then utilized in CNC machining to achieve the best outcomes possible throughout the machining process.

Advantages of Ultra High Precision – Swiss Machining


Precision machining includes equipment that interprets designs and executes them appropriately using computer animation drawings (CAM or CAD). These machines exceed humans in speed, accuracy, and total production output.

Operational Effectiveness

The precision machining process relies on computer-controlled machinery that can operate autonomously and at high speeds without human intervention. This implies that manufacturers can process components with a smaller workforce. Lowering manufacturing costs and increasing product quality can boost operational efficiency.

Consistent Quality

Swiss CNC machine provides constant output through precision machining. Traditional lathes or humans cannot match this consistency in quality.

Lower Error Rates

The automated precision machining process will take over once the necessary parameters are loaded into CNC machine equipment. Compared to manual processing, the possibility of mistakes is relatively minimal or negligible.

Lower Manufacturing Costs

Because of lower production costs, the industry increasingly relies on automated technologies to conduct its operations. CNC machines are often used to produce precise components. The thoroughness of this manufacturing process reduces waste, labor, and the possibility of errors.

Swiss Machining for Industrial Purposes

Manufacturers of complicated, critical, and distinct components rely on Swiss CNC Machining skills to supply the components they want at the highest quality, fastest possible pace, and lowest comparative price.

Working with professional and accredited Swiss CNC Machining shops delivers high-quality components to a wide range of manufacturers in several sectors, including aerospace, automotive, medical, and electronics. This preference is due to the rapid turnaround provided by Swiss screw machines. Automatic Swiss machines usually take two to three days to properly set up for production, whereas CNC machines may be ready for a new project in a day or less.
