Utilizing computer numerical control, or CNC, machining is a widely adopted manufacturing
technique that relies on automated, high-speed cutting tools to fashion designs from metal or
plastic stock. Common CNC machines include 3-axis, 4-axis, and 5-axis milling machines, lathes,
and routers.
The manner in which CNC parts are cut can vary, with scenarios where the workpiece remains
fixed while the tool moves, the tool remains stationary while the workpiece is rotated and moved,
or both the cutting tool and workpiece move simultaneously.
Product Details
CNC machining machines exhibit the capability to cut a diverse range of materials, including
aluminum, bronze, copper, ceramics, plywood, various steel alloys, stone, wood, zinc, and other
engineering materials.
This versatility makes CNC machining an ideal choice for generating prototypes in product
development. It enables precise and rapid adjustments until achieving the desired end product.

Company Profile
FAQ's
1. Do you offer Quick-Turn CNC Machining?
Indeed! Our Quick-Turn CNC Machining services provide fast lead times for parts, with many
available within 3-4 days. We also offer an expedite option, and our team is dedicated to working
closely with you to meet your most pressing deadlines.
2. How does you ensure the quality of my parts?
Upon confirmation of your order, a detailed Design for Manufacturing (DFM) review is carried out
to identify any potential issues affecting part quality. All incoming materials are meticulously
inspected and verified using a suite of testing equipment. Final inspection reports are generated as
part of our pre-shipment quality check.
Furthermore, we offer the option to share inspection data in real-time, enabling collaborative efforts
to address any quality concerns that may emerge during production.
3. What size of fillets are added when no specific fillet is specified by the 3D model or
drawing?
In cases where no specific fillet radius is specified in the 3D model or drawing, fillet radii will be
added by the machinist based on their judgment to enhance machining ease.
To ensure a desired fillet radius, specific details should be provided. For a general understanding,
internal vertical edge radii might surpass 1/3 of the depth, and internal horizontal edges may either
be maintained sharp or incorporate a radius within the range of 0.5mm to 1mm.
4. What industries do you typically work in? Who are your typical customers?
It's hard to find an industry we haven't collaborated with! Our clientele represents diverse sectors,
including heavy equipment manufacturing, general commercial enterprises, and businesses in
industrial, transportation, medical, and consumer domains, among others.
Our customer base extends across the United States, Europe, and beyond. What unites them is
a shared requirement for precision-machined parts delivered on time and within budget constraints.
