How to CNC machining PC?



Step 1. Convert the CAD file into a language that CNC machines can work with, that's G-code.


Step 2. The operator will place the PC workpiece that is cut to a specific size on the machine bed. Then it is time to mount the PC workpiece on the machined bed or by a vice.


Step 3. As the computer controls the CNC cutting tools to move to the pre-set coordinates, so precise positioning and alignment of the PC workpiece is significant to manufacture high-accuracy parts. Special metrology tools, probes, for instance, are ideal solutions for this step.


Step 4. Then, the PC workpiece is ready for machining. The machine uses professional cutting tools and rotating the at high speeds to remove material from the workpiece. However, at the very first steps, the machine removes at a relatively low speed and accuracy to gain an approximate geometry.


Step 5. Sometimes, the model is not being to achieve full features by single setup from the cutting tools, then to flip the PC workpiece is necessary.

Frequently Asked Questions

1. How much does it cost to CNC machining PC parts?

Prices are based on the structure of the part, order volume, machining processes, etc. You can use our instant quoting engine to get price, or you can email hello@wenext.com for more information.

2. What is polycarbonate (PC) CNC machining?

Polycarbonate (PC) CNC machining is the process of cutting and removing excess materials on the PC workpiece until the final object with desired geometries.

3. What kind of finishes are possible with polycarbonate (PC) CNC machining?

We provide various surface finishing options, including as machined, polishing, sandblasting, etc. Please check details Here.

4. What is polycarbonate (PC)?

Polycarbonate is a thermoplastic polymer containing carbonate groups in its chemical structures. Polycarbonate can be used in engineering applications as a strong and tough material, and some grades of polycarbonate are optically transparent.

5. What are the differences between polycarbonate and acrylic?

Both polycarbonate and acrylic have good optical features, high impact strength and stiffness. Polycarbonate offers more flexible grades and stronger impact strength. But acrylic is shiner, and the price of acrylic is lower than polycarbonate.

6. Will polycarbonate yellow over time?

Distinguished from acrylic, the clarity of polycarbonate will diminish over time and will adopt a yellow hue with prolonged exposure to the UV rays.
