What tolerance standards do you guarantee?

We guarantee that our manufacturing partners follow ISO 2768 standards for all CNC machined parts. Parts machined with metal will follow ISO 2768-m (medium) or ISO 2768-f (fine). Parts machined with plastics will follow 2768-m (medium). Geometric tolerances down to ± 0004 in. (0.010 mm) are possible but must be clearly indicated in technical drawings. We can achieve tighter tolerances on shafts with up to H7 fits with manual quoting and on occasion tighter.

What are the minimum and maximum dimensions you can machine?

At Hubs we offer CNC milling (​​3-axis, 3+2-axis and 5-axis) and turning. Milled parts can be machined up to 2000 x 1500 x 200 mm (78.7 x 59.0 x 7.8 in.) for 3/3+2 axis CNC milling. For 5-axis milling, the maximum part size is 650 x 650 x 300 mm (25.5 x 25.5 x 11.8 in.). The maximum diameter for CNC turning is 431mm (17 in.), length 990 mm (39 in). Minimum part dimensions recommended are around 0.39 x 0.39 x 0.39 in. (10 x 10 x 10mm).The minimum for feature dimensions is 0.5 mm.

We are limited to a 1000 mm (39 in.) maximum size for parts on our platform. If you need higher dimensions, you can place the request through your account manager.

What cosmetic standards do you guarantee?

Deburring and edge breaking are standard procedures for all CNC machined parts. If there are any critical edges that should be left sharp, they must be clearly indicated in technical drawings. Surfaces will be free of defects such as scratches, dents, stains, blemishes, hanging marks, minor defects. Surfaces indicated as critical (primary (a) side, as indicated on the technical drawing) will be free of mill steps and other marks. For the secondary (b) side, minor hanging marks and up to 2 minor defects are acceptable. A number of post-processing and finishing methods can be applied to improve the surface roughness, visual properties and wear resistance of machined parts.

How can I reduce the cost of my machined parts?

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.

The best way to reduce machining time is to design features that can be machined quickly, for example by choosing the correct radii for internal corners, reducing cavity depth, increasing wall thicknesses, limiting thread length and designing holes with standard sizes.

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).

Start-up costs can be reduced by reducing the number part rotations or repositioning required to finish the part, for example by separating geometries into multiple parts that can be assembled later.

Feature costs can be reduced by only using tolerances when strictly necessary, removing all text & lettering, and avoiding multiple surface finishes.

Where can I learn more about CNC machining?

Hubs was started by mechanical engineers and we have many more engineers and technicians in our team. Together 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 to read case studies, in-depth design guidelines and explanations of different surface finishes.

We’ve also written a complete engineering guide to CNC machining. Here you can learn about how the many different kinds of mills and lathes work and the different materials available, so you can easily compare their benefits & limitations. You’ll also learn the basic design rules for machining and the most common applications of each material and surface finish, so you can make the right choices every time.
