Milling means cutting or carving away material (metal, plastic, wood, etc.) using rotating multi-point cutting tools (like drills or end mills).
What CNC Milling Can Do:
Cut flat or curved surfaces with high precision.
Drill holes, slots, and pockets.
Produce complex 3D shapes that are difficult or impossible to make by hand.
CNC turning is a type of CNC machining that uses a rotating workpiece and a stationary cutting tool to remove material and shape the part.
How CNC Turning Works:
A rod or bar of material (metal, plastic, etc.) is clamped into a chuck and spun at high speed on a lathe.
A cutting tool moves along the surface of the rotating piece to cut, shave, or shape it into the desired form.
The process is computer-controlled, ensuring precise and consistent results.
Routing is a cutting or shaping process used to remove material from a surface — typically wood, plastic, or soft metals — using a rotating cutting tool called a router.
How Routing Works:
A router (handheld or CNC-controlled) holds a spinning bit that moves along a programmed path.
The bit cuts, carves, or trims the material to create shapes, grooves, or edges.
In CNC routing, a computer controls the motion, allowing for precise and repeatable cuts.
Standard (As-Milled)
This is the fastest finishing option. Parts retain visible tool marks and may have sharp edges or burrs, which can be removed upon request.

CNC Machining FAQs
How does CNC machining work?
CNC machining is a subtractive manufacturing process where material is cut away from solid stock to create a final part. During machining, holes are drilled, slots and channels are milled, and the raw material is shaped into precise forms with specific tapers, diameters, and geometries.
Unlike additive manufacturing, which builds parts layer by layer, or injection molding, which forms parts by injecting molten material into a mold, CNC machining creates shapes by removing excess material. This method delivers excellent accuracy and repeatability.
CNC machining is also highly versatile. It works with a wide range of materials, including metals, plastics, wood, glass, foam, and composites. Because of this flexibility and precision, CNC machining is widely used across many industries to produce high-quality, custom parts quickly and efficiently.
What are the advantages of cnc machining?
Benefits include tight tolerances, consistent batch quality, the capability to craft intricate designs, minimized scrap, and faster cycle times, whether the part is plastic or metal.
What types of materials can be used in cnc machining?
Almost any machinable material can be used—from engineering plastics and aluminum to stainless steel, brass, and specialty alloys. The best choice depends on your project’s performance needs, budget, and end-use application.
What industries use CNC machining?
CNC machining is widely used across industries. It is common in aerospace, automotive, consumer electronics, robotics, agriculture, and other fields that frequently use metal parts. It is also widely used in medical devices, household goods, energy, oil and gas, and other consumer applications. It is one of the most common manufacturing processes in the world.
What are your tolerances for CNC machined parts?
Most metal parts can hold +0.005″/–0.005″ local tolerances, while plastic parts typically maintain ±0.010″. Tolerances may change on large components, especially when maintaining flatness after heat treatment.
For CNC machining, an As-Milled finish delivers a minimum 125 µin surface finish.
All fabricated parts follow a standard 0.010″ dimensional tolerance and 1° angular tolerance to ensure reliable, consistent quality.
What is the difference between cnc milling and turning?
CNC milling uses a rotating cutting tool on a fixed workpiece, while CNC turning spins the part against a steady cutter. Both processes are essential for making high-precision components with tight tolerances.
