High Precision CNC Lathe Part CNC Milling Parts CNC Machining Copper Parts
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.

FAQ's
1. How much do CNC machining materials cost?
The cost of CNC machining materials is diverse and depends on the chosen material,
with variations in prices based on their physical properties.
A wide range of materials is available for CNC machining, each carrying a distinct price tag.
Aluminum 6061 stands out as the most economical choice for producing metal parts.
If affordability is a priority, ABS is the most budget-friendly option.
The ease of machining also influences costs, as seen with stainless steel.
Due to its hardness compared to aluminum, machining stainless steel is more challenging,
contributing to an elevated total cost.
2. What's the general surface texture of CNC milled and turned parts?
In the realm of CNC machining, the general surface texture of as-machined milled parts typically
exhibits a roughness of approximately 3.2μm (1.6μm for relatively new machines).
On the other hand, turned parts can achieve a finer surface with a roughness of 0.8μm.
Notably, this level of surface quality is attained without the need to adjust the machining speed.
3. Machined Parts Tolerances Overview:
Our tolerances for machined parts are as follows:
Local tolerances of +.005”/- .005” are applicable across most geometries in metals,
with a variation of +/- 0.010" for plastics. Tolerances may differ for large parts, particularly
concerning flatness over large parts after heat treatment.
For "As Milled" finish, a minimum surface finish of 125 is required for CNC parts.
All fabricated parts adhere to a dimensional tolerance of 0.010” and an angular tolerance of 1°.
Tapped holes not explicitly called out as features on the quoted CAD model may be machined to
the diameters specified in that model.
Surface treatments (e.g., anodize, bead blast, iridite, powder coat, etc.) will not be applied unless
explicitly paid for and acknowledged.
