What is Precision Machining?

Precision machining is a process that uses Computer Numerical Control (CNC) equipment to create parts with tight tolerances and high complexity. It requires a skilled operator and CNC software to guide the process.

Precision machining can be used on many different materials, including steel, bronze, and glass. It can be a cost-effective way to produce high-quality products.


Precision machining is a manufacturing process that uses a variety of machine tools, including milling, turning, and electrical discharge machining (EDM). Machinists control the machines using Computer Numerical Control (CNC) software and instructions.

Often, precision machining is required when a product needs to meet very precise design specifications. This is especially true in industries like aerospace and medical, where flaws in a part can have catastrophic consequences.

In the past, manufacturers used manual methods to create parts, a process that was both labor-intensive and costly. However, advances in technology allowed companies to utilize CNC machines to create parts and parts-based products with a much higher level of quality.

Precision machining is also safer for the workers who use it. As human errors are eliminated, there are fewer workplace accidents. Moreover, it allows for better material use and lower waste. As a result, the cost of machining is significantly less. This makes it a great choice for many industries.


Accuracy and precision are two of the primary quality standards in production machining. CNC machines are designed to meet these requirements.

The accuracy of a machine can be defined as the ability to hit a specific point with a certain degree of repeatability. For example, if a machine is 90% accurate, it will miss the mark about once every three shots, but it will still be pretty close to the mark on average.

Precision, on the other hand, is the ability of a machine to hit exactly the same point 100 times in a row. It’s not really important if it hits the spot, but it is essential that it does so consistently.

In QVI’s Rochester shop, the company has its own metrology expertise that enables it to verify the accuracy of its parts. For instance, the SmartScope Flash 302 contains several critical components machined by QVI.


Durability is the ability of a product, material or system to withstand damage or load conditions. This can include a computer’s capacity to recover from a crash or interruption in usage.

This is important for many industries, including aerospace and medical devices. If a part fails in flight or if a machine malfunctions, it can be disastrous for those using the product.

Precision machining is a high-precision process that requires extremely tight tolerances. This allows for the production of flawlessly-crafted parts with little chance of errors.

In addition to high accuracy, precision machining also reduces the amount of waste that can be produced during the manufacturing process. This can save companies money as they won’t have to waste materials on imperfect products that end up in the trash. It can also reduce the risk of workplace accidents as human error is significantly reduced when automated machines are used instead of hand-cut tools. This can result in higher safety for employees and a reduction of environmental impact.


Precision machining is a process that is used in many industries to manufacture tools and machines. This includes the automotive, medical, and aerospace industries.

This manufacturing method has numerous benefits for manufacturers. Among them are safety and efficiency.

It also reduces the need for human employees to perform tasks like cutting materials with CNC machining machines. This saves companies money on overhead costs and reduces the chances of error in production.

Another benefit is that it makes it possible to produce consistent outputs. This helps customers have a better understanding of the product that they are purchasing and improves customer confidence in a brand.

Quality machining requires precision workers to follow extremely specific blueprints produced by CAD (computer-aided design) or CAM (computer-aided manufacturing) programs such as AutoCAD and TurboCAD. These blueprints must be adhered to with great detail to ensure that a product retains its integrity.
