Crwon owns a complete line of advanced 3, 4, and 5 axis CNC machining centers with accurate GO/NO-GO gauges. It includes horizontal machining centers, turning centers, 5-axis machining centers, and rotary products, as well as a wide selection of fully integrated automation solutions. All machines were purchased by top machine manufacturers. We know the only way you make money is by making quality part. Our elite crew of factory-trained and -certified technicians have international manufacturing knowledge, and are available to help ensure you get the best service.

Why Use 5 Axis CNC Machining for Your Projects?

CNC machining is an ideal manufacturing solution, from rapid prototyping and small-medium production and even full production. More and more industry designers and engineering manufacturers would like to choose this process, since it helps engineers get achievement and reduce errors in a short time. It’s convinced that you just need to upload a CAD file to Crown for an Instant quoting, you will get a price, lead time and design-for-manufacturing feedback on your custom CNC parts. The fast 5 axis CNC machining can be very felxible for the volume according to your business plan.

The Tolerance of 5 axis CNC Machining Suggestions

Machining tolerance, also called dimensional accuracy, is the acceptable amount of variation in the size of a part. Regarding CNC machining, tolerances are used in two different contexts: in terms of CNC machine and in terms of CNC machining design. During the enquiry, we would like to share our experience of tolerance for design-for-manufacturing if you need it. Those suggestions will be based on:

Review the geometric tolerance. Sometimes too many geometric tolerances will affect the shape of the workpiece.
Orientation tolerance. It is the total amount of change allowed in the direction of the reference actual element relative to the reference, including parallelism, perpendicularity, and angularity.
Location tolerance. Before we put the part onto the 5 Axis machine, we will check out the correct location tolerance.
Run–out tolerance. It’s also the machining tolerance during the process we care about.

What Parts that We can Make with 5-Axis CNC Machining

Crown is an expert on aerospace, medical, and automative components, such as turbine wheels, spare parts, mold sections, impellers, and precise work pieces. With 5-Axis CNC machining, we also make automotive parts like gear boxes, starter motors, cylinder heads, custom components of vintage cars and rare cars. In the aerospace sector, the 5-Axis CNC Machine aids in making light weight and complex plastic parts. Apart from these, we build medical sector parts such as knee implants, surgical instruments like knives, scissors, stents, etc. Overall, any complex component can easily be built with 5-Axis CNC machining.
