CNC machining is a subtractive manufacturing process, meaning it achieves its final product by

removing material.

It involves tasks like drilling holes, creating slots and pathways, and shaping metal stock into

different forms with varying dimensions and designs.

Unlike additive manufacturing, which builds up materials layer by layer, CNC machining subtracts

material to create shapes.

It also differs from injection molding, where material is injected into a mold to form a specific shape.

CNC machining is highly versatile and compatible with a wide range of materials, including metals,

plastics, wood, glass, foam, and composites.

This versatility has made CNC machining a popular choice in various industries, offering efficient

and precise fabrication for designers and engineers.

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.

Post-processing and surface finishes for CNC machining

CNC-machined parts as they emerge from the machine often exhibit visible tool marks, a feature

that may not align with your specific part requirements.

Fortunately, there exists a multitude of post-processing techniques aimed at enhancing the surface

appearance and elevating attributes such as wear resistance, corrosion resistance, and chemical

resistance.

Methods like anodizing, bead blasting, and powder coating present viable options for refining the

final presentation of your custom parts, allowing you to achieve the desired surface quality and

performance characteristics.

CNC Machining Applications

Machined parts are widely used in a slew of industries, including aerospace, defense, robotics,

oil & gas, medical technology, research and more.

FAQ's

1. 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.

2. What are the default fillet sizes in the absence of specified dimensions from the 3D

model or drawing?

When specific fillet dimensions are not provided, we will apply fillet radii that facilitate machining,

as determined by our machinists' judgment.

If you require a particular fillet radius, please ensure it is specified.

In the absence of specific details, typical internal vertical edge radii may exceed 1/3 of the depth,

while internal horizontal edges can be either left sharp or have a radius ranging from 0.5mm to

1mm, depending on the machining requirements.

3. Benefits of CNC Machining

CNC machining offers several advantages, including:

1. Precision: CNC machines are capable of producing parts with exceptional precision, ensuring

consistent quality and eliminating human error.

2. Continuous Operation: CNC machines can operate 24/7 as long as they have a steady supply

of raw materials and fresh cutting tools. Robotic systems can be employed for material loading

and part unloading without the need for human intervention.

4. Can you provide passivation for my parts?

We offer passivation as a treatment option that can modify the surface chemistry of certain types

of metals.

This process is utilized for purposes such as corrosion protection, enhancing durability, improving

aesthetics, and more.
