CNC machining, standing for Computer Numerical Control machining, is a subtractive
manufacturing process utilized to fabricate parts by selectively removing material from a workpiece
or workpiece stock.
Precise control over the machine's movements is achieved through preprogrammed software and
codes. The scope of CNC machining encompasses various machinery types, including turning mills,
lathes, grinders, and plasma-cutting machines.

FAQ's
1. How much do CNC machining materials cost?
There are a ton of materials available for CNC machining, which means the cost varies quite a
bit between materials. Every material comes with a different price tag, and the physical properties
of each material influences the overall cost of machining.
Aluminum 6061 is the most economical option if you’re opting to produce metal parts.
ABS is the cheapest option. And in terms of how ease of machining affects the cost, stainless
steel is a good example. It’s much harder than aluminum and therefore more difficult to machine,
increasing the total cost.
2. What are your tolerances for machined parts?
For machined parts, our tolerances typically adhere to +.005”/- .005” local tolerances across most
metal geometries and +/- 0.010" for plastics. It's important to note that these tolerances may vary
for large parts, especially concerning flatness after heat treatment.
For an "As Milled" finish, a minimum surface finish of 125 is maintained for CNC parts.
Fabricated parts come with a 0.010” dimensional tolerance and a 1° angular tolerance.
Tapped holes not explicitly designated as features in the CAD model may be machined to the
diameters specified.
Additionally, no surface treatments, such as anodizing, bead blasting, iriditing, powder coating, etc.,
will be applied unless expressly paid for and acknowledged.
3. How does you ensure the quality of my parts?
Upon confirmation of your order, a comprehensive Design for Manufacturing (DFM) review is
conducted to identify any potential issues that could impact the quality of your parts.
All incoming materials undergo thorough inspection and verification using a suite of testing equipment.
Final inspection reports are generated before shipment. Additionally, we offer real-time sharing of
inspection data, fostering collaboration to address any quality concerns that may arise during production.
