Precision machining is what is recognized as a subtractive process. It removes material from precision mechanical components that meet the requirements using advanced software and equipment.

FREMONT, CA: Precision machined parts often have complex features and must meet exact requirements. Threads, holes, grooves, and tapers are examples of pieces that must align together with other components. Precision machining is commonly used to create metal parts that need to be precise for the component to work properly. For optimum efficiency, the components that make up an automobile engine, for example, need precise specifications. Since there is less space for error, machinists must use advanced equipment to achieve a tighter tolerance. Skilled CNC machine parts suppliers produce a wide variety of complex mechanical components that require close attention to detail using computer numerically operated machines, lathes, and presses.

Precision machining is what is recognized as a subtractive process. It removes material from precision mechanical components that meet the requirements using advanced software and equipment. CAD and CAM programs are often used in combination with the equipment and techniques used to machine precision mechanical components. Engineers use these programs to generate digital blueprints, which are then read by precision machining tools. This helps milling machines, lathes, and grinders extract the material with a higher degree of precision intricately as opposed to human-operated machines.

Swiss-type machines, lathes, and milling machines are popular processes and machines for precision CNC machine parts. Skilled manufacturers use CNC milling machines with three, four, and five axes. Furthermore, these machines allow for the development of complex mechanical components and milling from any angle. The workpiece is rotated against a cutting tool in a lathe. Lathes, like milling machines, receive instructions from a computer program and produce pieces with diameters ranging from 0.15 cm to 55 cm.

Precision machining of CNC mechanical parts is also done on Swiss-type machines. The first Swiss machines were created to manufacture the intricate components needed for Swiss watches. While a cutting tool trims the part to the desired specifications, the workpiece is secured to a sliding headstock and rotates around a spindle.
