CNC machining, distinct from traditional machining, accomplishes the same metal cutting, drilling,
milling, boring, grinding, and other metal forming and removal functions, but with the key
difference of utilizing computer numerical control instead of manual operation by a skilled machinist.
Traditional machining involves a manual approach where a machinist operates the machine,
removing or forming metal based on specifications from designers and engineers.
This process employs various tools such as turn wheels, dials, switches, chucks, vices, and cutting
tools made of materials like hardened steel, carbide, and industrial diamond.
In CNC machining, the automated process is driven by code developed by programmers, ensuring
consistent precision from the first cut to subsequent repetitions.
Commonly used in digital manufacturing and occasionally in low-volume production, CNC machining
allows for easy revisions and alterations for modifications and diverse materials.
While traditional machining is still relevant, CNC machining has largely superseded it in
manufacturing, fabrication, and industrial production due to its enhanced precision and automation.

FAQ's
1. What size of fillets are added when no specific fillet is specified by the 3D model
or drawing?
In the absence of a specified fillet radius in the 3D model or drawing, the machinist will add fillet
radii based on discretion to facilitate easy machining. Should a specific fillet radius be required,
clear specification is essential. As a general guideline, internal vertical edge radii might exceed
1/3 of the depth, while internal horizontal edges may either be left sharp or feature a radius
ranging from 0.5mm to 1mm.
2. Quality Assurance
We prioritize customer trust, integrating established quality management principles to elevate
customer satisfaction and perpetually enhance our performance and capabilities.
With decades of experience, we consistently meet stringent regulations and maintain PPAP
compliance for industries such as automotive, aerospace, and medical devices.
These standards serve as benchmarks, ensuring the quality of all products we manufacture.
3. What are you shipping terms?
Our standard shipping terms are Ex Works (EXW) for both rapid prototyping and regular
production orders. This implies that once the goods have left our premises, the customer assumes
responsibility for shipping, customs clearance, and all associated fees.
For express shipments, we employ Delivered Duty Unpaid (DDU), where the client is accountable
for paying import duty upon the arrival of the goods at the destination.
4. What if I am not completely satisfied with the parts I receive?
Our commitment extends to guaranteeing the quality of our materials and workmanship in
accordance with the terms specified in the initial order and the information supplied by you.
Any disputes arising from subjective assessments will be addressed by our management,
which will make every effort in good faith to ensure your complete satisfaction.
The foundation of our ongoing business is built on earning your confidence in our capacity to meet
and surpass reasonable expectations.
