CNC machining, an instrumental subtractive manufacturing method, is employed for crafting
components by systematically eliminating material from a workpiece or its stock.
The machine's operations are guided by preprogrammed software and codes, dictating the precise
movement of its equipment. This versatile process encompasses various machinery types, including
turning mills, lathes, grinders, and plasma-cutting machines.

Specialist Industries
The machining process is employed to manufacture rotational components, typically axi-symmetric,
featuring a range of characteristics such as holes, grooves, threads, tapers, various diameter steps,
and contoured surfaces.
Products crafted exclusively through turning often encompass items produced in small quantities,
particularly for prototypes, like custom-designed shafts and fasteners.
Turning is frequently utilized as a secondary procedure to incorporate or enhance features on
components initially manufactured using a different technique.
Examples of items manufactured through turning encompass camshafts, crankshafts, baseball bats,
bowls, cue sticks, signboards, musical instruments, and legs for tables and chairs.

FAQ's
1. How much does CNC machining cost?
The cost of CNC machining is determined by factors such as complexity, quantity, and lead time.
To obtain an accurate cost estimate, we recommend submitting a 3D CAD model.
This allows us to provide an interactive quote and offer design for manufacturability (DFM)
feedback. Notably, our use of proprietary software and automated fixturing processes eliminates
upfront non-recurring engineering (NRE) costs.
This approach ensures that even for quantities as low as 1 to 200 parts, CNC machining remains
a cost-effective option. While prices may be comparable to or slightly higher than 3D printing,
CNC machining provides enhanced material properties and surface finishes, making it a valuable
choice.
2. Quick Reference to CNC Machining Parameters
CNC machining parameters, crucially determined during G-code
generation by machine operators,
encompass the build size and accuracy of CNC machines, distinguishing them from 3D printers.
CNC milling systems offer a generous build area, capable of machining parts with dimensions up to
2,000 x 800 x 100 mm (78” x 32” x 40”). On the other hand, CNC turning systems specialize in
machining parts with a diameter of up to Ø 500 mm (Ø 20’’).
CNC machining excels in delivering high accuracy and tight tolerances. These machines can achieve
tolerances finer than half the diameter of an average human hair (± 0.025 mm or .001’’).
In instances where technical drawings lack specified tolerances, operators typically machine parts
with an accuracy of 0.125 mm (.005’’).
3. Surface Characteristics of CNC Milled and Turned Parts
CNC machining imparts specific surface textures to milled and
turned parts. As-machined milled
parts generally possess a roughness of around 3.2μm (with a potential improvement to 1.6μm for
newer machines). In contrast, turned parts showcase a finer surface texture, achieving a roughness
of 0.8μm. Remarkably, this enhanced surface quality is achieved without necessitating adjustments
to the machining speed.
