Precision machining, also known as micromachining or precision machining and tooling (PMT), is a type of manufacturing process that produces extremely precise shapes from metal, wood, glass, and other materials. Precision machining allows for complex shapes to be created in small volumes, with high precision and repeatability. These complex shapes can be used in many different industries including aerospace, medical devices, automotive parts production, and more!

Precision machining is the process of creating parts with a high degree of dimensional accuracy. It’s used to create parts that are used in a wide range of industries, such as aerospace, automotive, and medical equipment. Precision machining can be performed using many different methods depending on the type and size of the part being produced. For example, some precision machining processes require very little tooling while others require extensive equipment setups just to perform one operation. The biggest difference between these two types of processes is their tolerance level—the amount by which you want your finished product to vary from its original dimensions (more on tolerances later). Generally speaking, some jobs will also take longer than others depending on how much material needs to be removed during each cycle through the machine tool’s spindle (more on this later too).
WHAT IS PRECISION MACHINING USED FOR?
Precision machining is used to make parts for industrial equipment, such as wind turbines and power generation equipment. Precision machining is also used to make parts for medical devices, such as surgical instruments. It can be used to create consumer goods like smartphones and laptops. And precision machining is commonly employed in the auto industry to make car parts (and even whole cars).
HOW DOES PRECISION MACHINING WORK?
Precision machining is the process of making parts that must meet very tight tolerances. The part is held in a machine tool, which has a cutting tool with cutting edges on it. These cutting edges are sharpened to a very fine point and aligned so they can cut just enough material from the part to create an exact fit. As the cutting tool moves along on its surface, it removes material, creating what’s called a “wear pattern” on its surface.
WHAT TOOLS ARE USED FOR PRECISION MACHINING?
A variety of tools are used in precision machining, including Lathes and mills. These are used to rotate and move the workpiece about a tool bit. Machines may have one or more spindles that can spin the workpiece while milling and drilling operations take place. Shears, guillotines, and other automated cutting machines. These devices are used to cut metal sheets into smaller pieces for further processing or assembly by hand (e.g., bending).
Drill presses with vertical column-type beds that clamp onto a tabletop or bench so you can drill holes at various angles without having to hold the drill straight up against your workbench surface every time you need access from different angles with varying degrees of accuracy required for each hole drilled out on its own – depending on what type of job(s) needs doing at hand! This setup allows for greater flexibility when working with small parts like screws/bolts which require precise measurements before being inserted into an assembly line where all components must be perfectly lined up before proceeding further downstream towards completion – after all….time is money!
– LATHE
With a lathe, the workpiece is placed in a chuck and rotated by the motor while the cutting tool is moved through it to form the desired shape. This operation is called “turning”. Turning was developed into a more sophisticated machine capable of machining parts with high precision. Different types of lathes can be used for specific purposes such as thread grinding, turning, boring, etc…
– MILLING MACHINE
A milling machine is a machine tool used for milling, which is a machining process that uses a milling cutter to remove chips from the workpiece by cutting away material. The most common type of milling machine is the horizontal metal-cutting lathe; it can also be called a metalworking lathe (MWL) or universal tool and die/machining center. Other types include vertical metal-cutting lathes, which are sometimes referred to as universal machines because they have more capacity than their horizontal counterparts; and knee mills or knee lathes.
– SHEAR
A shear is a cutting tool that slices through metal. It can be used to cut plates, tubing, and bar stock. Shears are also used for making holes in metal, which are called “die holes.” The shear can also be used to make grooves in metal, which are called “slit grooves.”
– DRILL PRESS
A drill press is a drill that can be adjusted vertically and horizontally. It has a table that can be moved up and down, as well as left and right. This allows you to make more precise cuts than if you were using just the hand-held drill itself. The table’s surface area is also larger than that of a hand-held drill, allowing for larger pieces of material to be worked on at once.
– RADIAL ARM DRILL
A radial arm drill is similar in function to a vertical milling machine (the kind used in manufacturing) or lathe (the kind used in woodworking). It works by attaching your workpiece at one end using clamps or some other method, then rotating it around while performing various tasks on it with tools such as drills or saws attached via collets (small cylinders) mounted on arms extending from the base of the machine itself.
WHAT MATERIALS ARE USED FOR PRECISION MACHINING?
The materials used for precision machining can vary greatly, depending on the type of work and the end use. For example, many people think that a piece of metal is machined to create a material that has been shaped from another material. However, this is not always the case. Metals are often used in combination with other materials such as glass or ceramics during the process of precision machining. Some examples include:
- Brass
- Copper
- Aluminum
- Steel
– metals, including steel, aluminum, brass, and titanium
Precision machining is the process of cutting and shaping metals into pieces with very precise dimensions. The most common materials used for precision machining are steel, aluminum, brass, and titanium. These materials are often chosen because they are strong, durable, conductive (i.e., able to carry electricity), and easy to machine (i.e., cut).
– WOOD
Wood can be machined with a lathe, milling machine, shear, drill press, or radial arm drill. Wood is a good material for precision machining because it is relatively easy to work with and has few surface finish requirements. Wood is also relatively soft and can be cut easily to size, milled, or shaped without excessive wear on tools or tooling systems.
– GLASS AND CERAMICS, SUCH AS SLIP CAST PORCELAIN AND ZIRCONIA CERAMIC
You might be surprised to learn that machining glass and ceramics are quite common. These materials are often machined to create intricate shapes. Glass and ceramics are used in a wide variety of applications, including dental crowns, jewelry, and lenses. The machining process for these materials can be done using a variety of tools such as lathes and mills with diamond-tipped turning tools or end mills with diamond inserts up to 1 inch in diameter depending on your application requirements.
Precision machining can produce amazingly precise shapes, be it a ball bearing or a turbine blade. Precision machining is the process of using high-precision tools to produce parts with high precision. This manufacturing technique is most commonly associated with industries that require extremely precise components to function properly, like aerospace and medical applications. Precision machining can also be used for semiconductor manufacturing or even microelectronics.
FINAL THOUGHTS
Precision machining is an amazingly versatile process, and it’s one of the most important tools for creating anything from a small part of an engine to a large turbine blade. It’s also used in many other industries, including aerospace and medical devices. Precision machining is an excellent way to create parts with tight tolerances and smooth finishes that look professional.
