Spare Part
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. Why choose CNC machining?
Opting for CNC machining brings forth speed, accuracy, and versatility. This manufacturing solution
stands out as it swiftly delivers end-use parts at any volume without the requirement for substantial
investments in hard tooling or costly set-ups.
2. 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.
3. What are the advantages of CNC machining?
The advantages of CNC machining are multifaceted, including rapid prototyping and the swift
production of full-scale parts. Notably, it excels in delivering high precision and accuracy in
manufacturing across various part sizes. CNC machining enables tight tolerance machining for parts
of all dimensions.
Furthermore, it provides unparalleled flexibility in terms of volume, pricing, lead times, and the
diverse range of materials and finishes utilized.
4. 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.
