The most suitable application for CNC machining lies in one-off manufacturing endeavors and in
low-to-medium volume production scenarios, typically ranging from several hundred to 1000 parts.
Opting for CNC machining is particularly advantageous when aiming for cost-competitive metal
prototypes. Additionally, the technology shines in situations where the parts necessitate extremely
tight tolerances for precision.
Product Details
CNC machining machines possess the versatility to cut through an extensive array of materials,
encompassing aluminum, bronze, copper, ceramics, plywood, diverse steel types, stone, wood,
zinc, and various engineering materials.
This broad range of capabilities positions CNC machining as an optimal solution for prototype
creation in product development. It facilitates the ability to make accurate and swift adjustments
until achieving satisfaction with the final product.

Company Profile
FAQ's
1. How can I ensure my design is confidential?
We prioritize the confidentiality of your design, and to reinforce this commitment, we are willing
to enter into a Non-disclosure Agreement (NDA) with our customers. This agreement can be
established prior to the quoting phase or when placing an order, ensuring a secure environment
for your proprietary information.
2. How long does a quotation take?
Under normal circumstances, we endeavor to respond to Requests for Quotation (RFQ) within a
couple of days from the time of submission. Should there be any unforeseen delays in the
quotation process, we commit to informing you as soon as possible.
3. What tolerances can achieve?
Tolerances are not universally defined and vary based on factors such as part size, design geometry,
the number and size of features, material selection, surface finish, and the manufacturing process.
After order confirmation, we conduct a comprehensive Design for Manufacturing review to identify
areas for potential modification to enhance manufacturability. It is advantageous if you can specify
critical tolerance areas in your design, allowing for adjustments to optimize production time and
costs.
General tolerance guidelines are provided for CNC machining in metal and plastic, plastic injection
molding, CNC metals and plastic injection molding materials, metal 3D printing (+/- 0.5mm), and
an expected shrinkage rate of +/- 0.15% for vacuum casting. Clear specifications in the 2D drawings
are essential for precise adherence to manufacturing and technical requirements.
4. Can passivate my parts?
Passivation is a treatment designed to change the surface chemistry of select metals. We offer
passivation services to provide corrosion protection, improve durability, enhance aesthetics, and more.
