CNC prototyping offers excellent tolerances and other advantages compared to other manufacturing methods, which make the process suitable for a range of industries. Below is a further look at examples of these industries.

Examples of CNC machining services we provide

Medical industry

The medical industry relies heavily on the accuracy of its tools. In enough cases, an error of 0.01 mm may be all that is needed for patient survival. For example, a medical scalpel must be sharp for best results. How do you think we sand or even make them? Another case is high-speed medical centrifuges. Doctors use them to ferment or isolate chemicals. They do this by spinning at incredible speeds, some reaching 100,000 RPM. Friction is a common problem that can arise in this case.

To withstand friction, we mount the main shaft in airfoil bearings. It took multiple tests to perfect, so CNC prototyping became key. The shaft rotates in air. At such high speeds, variations in the spindle runout can cause excessive friction, which can lead to bearing burnout and spindle ejection from the centrifuge. The only way we were able to get a precise axis was through continuous CNC prototyping. We can then proceed to grind and polish it to meet the customer's needs. What the main professional CNC machining offers is that it first allows us to achieve the required tolerances and then we can easily repeat it using the CNC program that is set up.

Aerospace industry

The space shuttle is some of the most complex inventions ever made by mankind. The components that make up the engine work under the highest possible pressure and the harshest conditions. These include high temperatures, corrosive elements and other dynamic forces. These conditions reduce the useful life of most aerospace components. Fortunately, after a lot of trial and error with CNC machining, we can produce a reliable machine.

We start by making aerospace parts from durable and strong materials. However, these durable materials happen to be difficult to machine. They require the toughest tool materials to machine them, and material selection is followed by a complex process. Furthermore, it requires a continuous processing method.

For example, we turn or mill it a few times. We do this at different speeds and feed rates. Then we went ahead and sanded it with a few different wheels and polished it to perfection. Every process requires top-notch precision, which might not be possible without CNC machining.

Power industry

CNC machining accounts for at least 60% of steam turbine manufacturing time. The most complex part of the system is the turbine blades. We usually mass produce them by casting. In terms of prototyping, it's a little different. Casting happens to be more expensive than CNC milling, and milling ends up being the first choice. We start by cutting the entire blade from a blank cylinder. We then went on to do various experiments with it, which helped us determine if it could withstand the temperature and load.

Automobile industry

CNC model processing

The auto industry is known for constantly reinventing itself. New cars appear every year at a mass-production pace. CNC machining plays an important role in this situation. This is due to the CNC programs we write as templates for mass-produced cars. In addition, CNC prototyping has proven to be critical for building automotive engines, as it requires high tolerances of a few microns between the valve seat and the piston. We also use it to make very clear headlights. It uses precise diamond cutting tools that move quickly with minimal feed rates.

Electrical industry

Metals are key materials for making circuits, fans, processors and resistors. Most circuit boards are small and require precise connections to avoid shorts. CNC machining is essential for making top-notch electronics.

What can we offer for your CNC project?

CNC machining is a vital process that offers a range of options when machining materials. Therefore, we must take full advantage of all it has to offer. Below is a summary of how we utilize CNC machining.

First, we can use it in roughing operations to get a blank from a piece of metal. We can use it further to get a top-notch fine surface finish. In addition, we can process a certain amount of material. Either as soft as plastic or the hardest are nickel and titanium alloys. In addition, we can easily machine geometrically complex designs. Our Xiehe experts only need a short time to design a CNC program for your prototype.
