5-Axis CNC Machining

What is SWISS CNC Machining?

CNC turning produces parts by mounting a blank on a rotating chuck and removing material using stationary cutting tools. This technology is ideal for manufacturing parts with symmetry along their center axis. Turned parts are typically produced faster (and at a lower cost) than milled parts.

CNC Machining Tolerances

We are able to offer a precision machining service with a wide array of tolerances.

Feature	Description
Maximum Part Size	Milled parts up to 80” x 48” x 24” (2,032 x 1,219 x 610 mm). Lathe parts up to 62” (1,575 mm) length and 32” (813 mm) diameter.
Standard Lead Time	3 business days
General Tolerances	Tolerances on metals will be held to +/- 0.005" (+/- 0.127 mm) in accordance with ISO 2768 unless otherwise specified. Plastics and composites will be +/- 0.010”.
Precision Tolerances	Sunnyhowe can manufacture and inspect to tight tolerances, including sub +/- 0.001" tolerances, per your drawing specifications and GD&T callouts.
Minimum Feature Size	0.020” (0.50 mm). This may vary depending on part geometry and chosen material.
Threads and Tapped Holes	Sunnyhowe can accommodate any standard thread size. We can also machine custom threads; these will require a manual quote review.
Edge Condition	Sharp edges are broken and deburred by default
Surface Finish	The standard finish is as-machined: 125 Ra or better. Additional finishing options can be specified when getting a quote.

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.

How does CNC machining work?

CNC machining uses subtractive processes, which means feedstock is machined to its final form by subtracting and removing material. Holes are drilled, lots and pathways are bored, and metal stock is shaped into new material with varying tapers, diameters, and shapes.

For subtractive manufacturing, shapes are achieved by the subtraction of material. This contrasts with other types such as additive manufacturing — where materials are added, layered, and deformed to a specified shape. It also contrasts with injection molding where the material is injected in a different state of matter, using a mold, and formed to a specified shape.

CNC machining is versatile — and can be used with various materials, including metals, plastics, wood, glass, foam, and other composite materials. This versatility has helped make CNC machining a popular choice across industries, enabling designers and engineers to fabricate products efficiently and precisely.

How does CNC machining differ from traditional machining?

In traditional machining, a skilled machinist operates a machine, removing or forming metal. This is done according to specifications provided by designers and engineers, usually through an engineering drawing or blueprint. They use turn wheels, dials, switches, chucks, vices, and a variety of cutting tools made of hardened steel, carbide, and industrial diamond, then use measurement instruments to ensure all of the dimensions are correct.

CNC machining performs the same function as traditional machining — metal cutting, drilling, milling, boring, grinding, and other metal forming and removal functions — but CNC machines use computer numerical control rather than manual control by a machinist. It is automated, driven by code, and developed by programmers. It is about as precise the first time of cutting as the 500th. Widely used in digital manufacturing (and sometimes in low-volume production runs), it can be revised and altered for modifications and different materials.

This type of machining is much more precise and has superseded traditional machining (though not entirely) in manufacturing, fabrication, and industrial production. It uses mathematical coordinates and computing power to achieve the same end with the greatest accuracy. Specifically, computer numerical control uses Cartesian coordinates. These are spatial coordinates — in several dimensions — using coordinates and axes. The automation of cutting tool machines controls its cutting, boring, drilling, or other operation using the numerical control of a computer that reads the coordinates. These coordinates were designated by engineers in the product’s digital drawing and design.
