Parts Turning and Milling CNC Composite Parts
CNC Milling is an automated machining process utilized to fabricate 2D and 3D CNC parts by
subtracting material from raw stock.
Workshops employ CNC milling machines to enhance manufacturing efficiency and save time.
To create a CNC milled part, a block or sheet of material is positioned on a table beneath a
spindle equipped with a cutting tool.
A computerized system determines the tool selection, spindle rotation speed, vertical spindle
movement, and horizontal table motion.
This enables tools like drills, taps, and end mills to remove material sections and shape the
workpiece.
CNC Milling is a widely adopted manufacturing method renowned for its precision and accuracy.
It involves the use of a 3D CAD design, tooling, and machining equipment like heavy-duty drill
presses and CNC machines to produce custom 3D CAD models.
This process can produce CNC parts from materials such as plastic, metal, and others, achieving
tight tolerances and impeccable surface finishes.
CNC milling serves both prototyping and production needs, accommodating intricate designs and
delivering high-precision CNC parts that meet precise specifications and tolerances in a short
timeframe.
Additionally, it can produce parts with specified surface finishes, ensuring uniformity that aligns
with exact requirements and tolerances.
Product Details
CNC milling machines excel at cutting a wide range of materials, including aluminum, bronze,
copper, ceramics, plywood, various steel types, stone, wood, zinc, and numerous engineering
materials.
This versatility makes them perfect for crafting prototypes during product development.
With CNC milling, you can easily fine-tune and make precise adjustments until you achieve the
desired final product, offering accuracy and efficiency throughout the manufacturing process.

FAQ's
1. What Products Are Crafted Through Turning?
Turning is employed in the fabrication of rotational, predominantly axi-symmetric components
that encompass a myriad of features.
These features may include apertures, grooves, threads, tapers, varying diameter transitions,
and even intricately contoured surfaces.
Products that are entirely manufactured through turning are frequently comprised of components
produced in limited quantities, particularly for prototypes. Such components may include bespoke
shafts and fasteners.
Moreover, turning is frequently utilized as a secondary process to introduce or enhance features
on components that were originally produced using alternative manufacturing techniques.
Illustrative examples of products that undergo the turning process encompass camshafts,
crankshafts, baseball bats, bowls, cue sticks, signage, musical instruments, as well as table
and chair legs.
2. What is your typical lead time? Can my parts be produced urgently?
