Our CNC turning process enables the rapid production of custom prototypes and end-use production
parts, often with turnaround times as short as 1 day.
Utilizing a CNC lathe equipped with live tooling capabilities, we can efficiently machine various
features, including axial and radial holes, flats, grooves, and slots.
CNC turning is commonly employed for the following applications:
Functional prototypes and end-use components.
Parts featuring cylindrical characteristics.
Components with axial and radial holes, flats, grooves, and slots.
Product Details
The primary materials employed in the CNC machining process are predominantly metals.
These metals encompass alloy steel, carbon steel, cast iron, stainless steel, aluminum, copper,
magnesium, and zinc.
However, CNC machining is not limited to metals alone; it is also capable of machining plastic
parts and working with various materials, including ceramics, composites, thermoplastics,
and thermosets.

FAQ's
1. How much do CNC machining materials cost?
The cost of CNC machining materials is influenced by the selected material, with each material
carrying its own price tag based on unique physical properties. The variety of materials available
for CNC machining contributes to the diverse cost landscape.
For metal parts production, Aluminum 6061 emerges as the most cost-effective option.
If cost efficiency is paramount, ABS is the most economical choice. The ease of machining plays
a significant role in cost dynamics, exemplified by stainless steel. Its greater hardness relative to
aluminum increases machining complexity, resulting in a higher overall cost.
2. Tolerance Specifications for Machined Parts
Our tolerances for machined parts are outlined below:
Local tolerances of +.005”/- .005” are applied across most geometries in metals, while plastics
have a tolerance variation of +/- 0.010". Tolerance specifications may vary for large parts,
especially concerning flatness after heat treatment.
For CNC parts with an "As Milled" finish, a minimum surface finish of 125 is required.
Fabricated parts adhere to a dimensional tolerance of 0.010” and an angular tolerance of 1°.
Tapped holes not explicitly identified 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
specifically paid for and acknowledged.
3. How long does delivery time and quotation take?
The delivery time for parts is determined by their complexity:
Low-complexity parts: 2-3 days
Moderate-complexity parts: 2-5 days
High-complexity parts: 5-15 days
Quoting time varies based on design complexity:
Simple designs: 1 business day or faster
Moderate to complex designs: 3+ business days
