Custom CNC Machining Milling Milled Parts Turning Turned CNC Lathe Service
Part Stainless Steel Metal Machined Part
Various CNC machines are tailored to specific machining tasks, depending on the part requirements.
CNC milling employs CNC mills equipped with multi-axis systems (typically three, four, or five axes),
ideal for intricate parts.
CNC turning employs Lathe machines with generally two axes, utilizing circular motion for cutting.
Electric discharge machines (EDM) employ electrical sparks to shape workpieces.
Hobbing is employed for cutting gears, splines, and sprockets. Other CNC machine types
encompass plasma cutters and water jet cutters, each catering to distinct manufacturing needs.
Product Details
CNC 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 is your typical lead time? Can my parts be produced on a rush basis?
Our standard lead time for screw machine products, from quoting to manufacturing and shipping,
is approximately one week, with an on-time delivery rate of over 99%.
Depending on factors like tooling, gauges, and material availability, we might accommodate
expedited production for your parts. Feel free to inquire!
2. How Much Does CNC Machining Cost?
The cost of CNC machining a part can vary based on several factors, including:
1. Material: The choice of material affects the cost, with some materials being more expensive to
machine due to tool wear and cutting speeds.
2. Complexity: Parts with complex features are more costly to machine compared to simpler designs.
3. Tolerances: Tight dimensional tolerances increase machining costs, so it's essential to specify
them only when necessary.
4. Surface Finish: Achieving mirror finishes requires specialized tools and strategies, which can
add to the overall cost.
5. Quantity: Low-volume production tends to be more expensive per part than large-volume
production due to setup and programming costs.
3. What are your tolerances for machined parts?
Our tolerances for machined parts are typically within +0.005"/-0.005" for most metal geometries,
and within +/- 0.010" for plastics.
However, tolerances may vary for larger parts, especially when maintaining flatness over extensive
sections post-heat treatment.
Regarding the finish requirements, an "As Milled" finish should have a minimum of 125 surface finish
for CNC parts.
For all fabricated parts, there is a dimensional tolerance of 0.010" and an angular tolerance of 1°.
Please note that tapped holes not explicitly indicated as features in the provided CAD model may
be machined to the specified diameters in that model.
Additionally, surface treatments like anodizing, bead blasting, iriditing, powder coating, etc.,
will only be applied if they have been paid for and explicitly acknowledged in advance.
