Custom Online CNC Machining Service

The main costs associated with CNC machining can be grouped into machining time, start-up costs, material costs, and feature costs. To reduce costs you need to understand the impact of these factors on cost.

1. The best way to reduce machining time is to design features that can be machined quickly, for instance, choosing the correct radii for internal corners, reducing cavity depth, increasing wall thicknesses, limiting thread length, and designing holes with standard sizes.
2. Material costs can be reduced by considering the size of the blank required, and the cost and machinability of the bulk material (softer alloys are faster to machine).
3. Start-up costs can be reduced by reducing the number of part rotations or repositioning required to finish the part, for example, separating geometries into multiple parts that can be assembled later.
4. Feature costs can be reduced by only using tolerances when strictly necessary, removing all text & lettering, and avoiding multiple surface finishes.

Our sound quality-control system makes sense that thousands of customers place their CNC machining orders in our company. The regular check and testing starts from incoming materials to shipment, ensuring each part is produced accurately for your specifications.

We possess a comprehensive, standardized inspection report with every order to ensure quality metrics are being met, and offer a first article inspection service on orders of 100+ units. We also have multiple certifications available on request, including but not limited to ISO9001, ISO13485, and AS9100.

Follow this page - Runsom Quality Control Standard to know more about our quality assurance measures.

Due to the spinning motion produced by the CNC milling machine's cutter, the surface finish of CNC machined parts will have visible tool marks. If you require a smooth, unblemished finish for your parts, we recommend choosing a secondary finish: grained finish (can only be applied to the outside of machined enclosures due to geometry) or powder coat.

To know more information about surface finishes for CNC machining, you can refer to this article.

CNC machining is widely used across a wide range of industries. It is common in aerospace, automotive, consumer electronics, robotics, agriculture, and other fields that frequently use metal parts. It is also widely used in medical devices, household goods, energy, oil and gas, and other consumer applications. It is one of the most common processing methods in the manufacturing field.

Runsom has offered ultra-precision CNC crafted components for global industries including oil and gas CNC machining, medical instruments CNC machining, optical CNC machining, tool and die parts CNC machining, motorcycle components CNC machining, electronic enclosures CNC machining, automotive parts CNC machining, etc.

Runsom was established by mechanical engineers and now we have a talented and powerful team. Until now, we've written a lot of content on CNC machining over the years. You can find a selection of resources below, or you can head to our knowledge hub and filter on CNC machining case studies, in-depth design guidelines, and explanations of different surface finishes.

We've also written a complete CNC machining design guide, which has been updated for 2020. Here you can learn about how many different kinds of mills and lathes work and how to select the best suitable materials for CNC machining, so you can easily figure out their benefits & limitations. You'll also learn the basic design rules for machining, the most common applications of each material, and surface finishes available for CNC machining, so you can make the right choice every time.
