Operating as a subtractive manufacturing process, CNC machining involves the creation of parts
by removing material from a workpiece or workpiece stock. The machine's movement is governed
by preprogrammed software and codes, ensuring precise control over material removal.
This expansive process includes a diverse range of machinery, such as turning mills, lathes,
grinders, and plasma-cutting machines.
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.

2. What industries do you typically work in? Who are your typical customers?
Virtually no industry is unfamiliar to us! Our customers hail from various sectors, encompassing
heavy equipment manufacturing, general commercial enterprises, and entities in industrial,
transportation, medical, and consumer realms, among others.
While our clientele spans the globe, reaching the United States, Europe, and beyond, they all
share a common need for impeccably machined parts, adhering to specifications, delivered
promptly, and meeting budgetary considerations.
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.
