CNC Precision Machined Components Stainless Steel Part CNC Machining Milling

CNC Part Manufacturer

 

CNC machining encompasses a wide array of machinery, all of which employ computer-controlled

machine tools to eliminate material from a workpiece.

 

The utilization of computer control imparts CNC machining with a remarkable advantage in terms

of speed, precision, and accuracy when compared to traditional machining methods.

 

Product Details

 

CNC milling encompasses a wide range of materials, primarily categorized into three major

groups: plastics, soft metals, and hard metals. These materials include aluminum, bronze,

copper, ceramics, plywood, steel, stone, wood, zinc, and numerous others.

 

The choice of material depends on ease of workability and desired properties, with those

offering favorable characteristics often being preferred in CNC milling applications.

Specialist Industries

 

CNC machining is employed to fabricate products composed of glass, metal, plastic, wood,

and custom-designed components. Machinists utilize this process to create prototypes and items

for various industries, including aerospace, automotive, hardware startups, manufacturing, medical

devices, robotics, and others.

FAQ's

 

1. Cost of CNC Machining


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.

 

2. 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.

 

3. What is the typical delivery time and quotation process?


Delivery time is determined based on the complexity of the parts. For low-complexity parts,

the lead time is typically 2-3 days. As the complexity of the parts increases, the lead time can

range from 2-5 days. High-complexity parts may require a lead time of 5-15 days.


Similarly, the quotation process varies depending on the complexity of your design. Quotes can

be provided in as little as 1 business day, or it may take 3 or more business days for more intricate

designs.


If you have a design that you would like our team to assess and provide a quote for, please don't

hesitate to contact us.
