Precision Machining Manufacture

Precision machining is a manufacturing process that utilizes computerized machine tools to produce precise and accurate parts. It involves cutting, shaping, and drilling metal or plastic parts to exact specifications. In recent years, precision machining has become an essential component of modern manufacturing, providing businesses with a wide range of benefits.

This technique has the potential to significantly minimize manufacturing costs due to the lower likelihood of errors and delivering inferior results. In addition, it guarantees correct outcomes and gives companies a clear financial plan for production. As a result, it promotes better control over production costs.

Precision Machining Methods

There are several precision machining processes, each with strengths and limitations. Some of the most common techniques include:


To remove material, a cylindrical workpiece is rotated as a cutting tool travels along the axis of the workpiece. Turning is employed to manufacture round objects with exact diameters and smooth surfaces.


With milling, a revolving cutter moves in a linear path to remove material from a workpiece. It is used to create flat surfaces, slots, grooves, and other exact designs.


A cutting tool creates a cylindrical hole in a workpiece during this drilling. Its purpose is to develop exact diameter and depth holes.


Grinding involves removing material from a workpiece with an abrasive wheel. It’s utilized to manufacture products with tight tolerances and highly polished surfaces.

EDM (Electrical Discharge Machining)

This procedure uses an electrical discharge to erode material from a workpiece. Thus, EDM is applied to create complicated forms and precision features, particularly in difficult-to-machine materials.

Lapping and Honing

An abrasive substance and a spinning tool are used in lapping and honing to generate a highly polished surface on a workpiece. These techniques are employed to obtain tight tolerances and increase surface smoothness.

Micro Machining

Micro machining is a method in which tiny pieces with extremely tight tolerances and great accuracy are produced. It is used in various industries, including electronics, medical devices, and aircraft.

Selection of Precision Machining Method

Selecting a precision machining method is crucial to the success of any manufacturing project. Here are the factors that should be evaluated to determine the best machining method for a given application:


A material’s properties — such as hardness, strength, and ductility — directly impact the machining process. For instance, harder materials may require specialized cutting tools and different machining methods, while softer materials may be machined using more conventional methods.

Dimensional Accuracy

Dimensional accuracy refers to how precisely the machined parts conform to the desired specifications. The desired dimensional accuracy can be influenced by the design requirements, the part’s intended use, and the manufacturing tolerance. Higher dimensional accuracy may require slower cutting speeds, multiple machining operations, or specialized equipment.

Surface Finish

Surface finish refers to the texture and roughness of the machined surface and can affect the functional and aesthetic properties of the part. A smooth surface finish may require multiple machining operations or a specialized finishing process. Meanwhile, a rougher surface finish may be achieved with a single machining operation.

Complexity of Part

Complex parts can refer to those with intricate shapes, multiple features, or challenging geometries that require specialized cutting tools and techniques. For example, a complicated component may require five-axis machining centers, while simpler forms may be machined using more conventional methods.

Production Volume

High-volume production often requires specialized equipment, such as CNC machines. However, these can produce parts quickly and accurately in large quantities. In addition, some precision machining methods, such as stamping or forging, are well-suited for high-volume production. In contrast, others — such as wire EDM or sinker EDM — may be better suited for lower-volume production runs.

Industries That Use Precision Machining

Here are some of the industries that incorporate precision machining in their operations:


Precision machining is widely used in aerospace manufacturing, such as aircraft, helicopters, satellites, and other systems. Particularly, engines, landing gear, airframes, and control systems can be achieved through this method.


This manufacturing process is used in automotive parts for cars, trucks, and other vehicles. Engine components, transmission components, suspension systems, and braking systems are some components produced through precision machining. These parts often require close tolerances and high levels of consistency to ensure vehicle performance and reliability.


Precision machining is used to manufacture medical implants, surgical instruments, and other medical devices that must meet stringent quality, safety, and performance standards. These medical devices must be designed and manufactured to exact specifications to ensure they perform optimally and effectively.


This technique is a crucial technology used in the defense industry to manufacture components for military equipment, weapons systems, and other defense-related products. Precision machining allows producing high-quality, precise, and reliable parts that meet the demanding requirements of military equipment.


The electronics industry benefits from precision machining. It can fabricate components for various electronic devices, such as computers, cell phones, and other electronics.

Oil & Gas

Precision machining is used to manufacture components for oil and gas equipment, such as drilling equipment, valves, and pipelines. These components must be made to exact tolerances to ensure proper function and safety in harsh environments.
