CNC machining cost is mainly made of machining time, start-up cost, material cost and feature cost. In order to control cost, these factors will help you to some extent.

A design of fast machined features is the best way to reduce machining time. You could design by using correct inner radii, reducing cavity depth, increasing wall thickness, limiting thread length and choosing standard-sized holes and so forth.

Start-up cost can drop through reducing the number of part rotations or repositioning during machining. For instance, you could split the geometry into several parts to assemble them together.

Material cost reduction needs to consider the size of the required stock and both the cost and the machinability of big material. Soft alloys can be generally machined faster.

Feature cost control can consider using tolerances as necessary only, avoiding logo machining and multiple surface treatments.

At Runsom, we treat your order seriously and attach great importance to the quality.

To ensure high-quality parts, any suppliers can not go into our manufacturing network except for the verified ones. We have a strict process of selecting the best suppliers as our manufacturing partners. Every partner is verified and we implement regular quality inspections on their factories every year.

Our QC carries out inspections several times from pre-production, in-production and after production to make sure of every detail of the parts within the specification. We issue a comprehensive and standardized dimensions inspection report for each order and offer a first article inspection service on bulk production.

Different certifications are available on request including but not limited to ISO9001, ISO13485 and AS9100.

Runsom was founded by mechanical engineers and composed by a team of experienced engineers and technicians. We have written a lot of content about CNC machining over the years. You can find a range of resources on our website catalogue where you could have case studies, in-depth design guides and explanations of different surface treatments, etc.

We have also compiled a complete engineering guide of CNC machining and you can learn about the working principles of many different types of milling and turning lathes and the available different materials to compare their advantages and limitations easily. You can also learn the basic design rules of machining and the most common applications of each material and surface finish so that you can make the best choice every time.

As one of the most common manufacturing processes in the world, CNC machining is widely used in various industries including aerospace, automotive, consumer electronics, robotics, agriculture and other fields where metal and plastic parts are frequently used. It is also applied to medical equipment, household products, energy, oil and gas, and other consumer applications.

Due to rotational movement, CNC machine tool leaves obvious machining marks on the surface of the part. If the part requires a smooth and flawless surface, we recommend that you do a secondary surface treatment: powder coating or grained finish which can only be used on the outside of the machined enclosures owing to the geometric shape.
