The functioning of CNC machining is characterized by subtractive processes, wherein the
feedstock is machined to its final form by the removal of material.
This process encompasses activities such as drilling holes, boring lots and pathways, and shaping
metal stock into new material with varying tapers, diameters, and shapes.
Unlike additive manufacturing methods that involve the addition, layering, and deformation of
materials to achieve a specified shape, CNC machining achieves shapes through the removal of
material.
This sets it apart from injection molding, where material is injected in a different state of matter
using a mold and formed to a predetermined shape.

FAQ's
1. How long does delivery time and quotation take?
The delivery time for parts is determined by their complexity. Parts with low complexity typically
have a lead time of 2-3 days, while moderate complexity extends the lead time to 2-5 days.
High-complexity parts may require 5 to 15 days for delivery. Quoting time varies based on design
complexity, ranging from 1 business day (or faster) for simpler designs to 3+ business days for
more intricate ones. For an assessment and quote for your design, please feel free to reach out
to our team.
2. What are standard machining tolerances?
The standard machining tolerance is ± 0.005" or 0.13mm, representing the allowable range for a
dimension. For instance, if a CNC machining tool has a tolerance of ± 0.01 mm, it implies a
permissible deviation of 0.01 mm in each cut.
With a provided drawing, our CNC machining service can achieve part tolerances as low as
± 0.0002 in. In the absence of a drawing, all CNC parts adhere to our ISO 2768 medium standard.
For projects demanding tighter tolerances, ±0.025mm or ±0.001", we can accommodate with an
engineering drawing specifying critical features.
3. How does compare to other suppliers on price?
While direct comparisons can be challenging, generally, We offers prices that are typically 25-45%
lower for plastic injection mold tools and CNC machined/turned parts when compared to suppliers
in North America and Europe.
4. Can passivate my parts?
Passivation is a treatment that alters the surface chemistry of certain types of metals. We provide
passivation services for corrosion protection, enhanced durability, improved aesthetics, and more.
