CNC Machining FAQ

Q When should I choose CNC Machining Services?

A
Machined parts have the true properties of the material you select. Our process allows you to get parts machined from blocks of solid plastic and metal in the same time frame.

We mill and turn low quantities of parts very quickly. Typical quantities are one to 200 pieces and manufacturing times are 1 to 3 business days. We offer product developers parts machined from engineering-grade materials that are suitable for functional testing or end-use applications.

CNC machining is more expensive than plastic 3D printing, but it is the most feasible option for metal visual prototypes given the high cost of metal 3D printing and metal casting.
Q Can I get tight tolerances CNC parts from Jucheng Precision?

A
Jucheng Precision is known as one of the best CNC machining companies in China in terms of quality, speed, and customer service. With high-quality CNC machines, we can easily achieve +/- 0.02mm of tolerance and can even get within +/- 0.01mm. But keep in mind that it can have an impact on the cost.
Q Can I order just one piece?

A
Yes, of course you can, there is no minimum quantity at Jucheng Precision, we will recommend you with the most suitable and effective manufacturing solutions based on your quantities.
Q Can Jucheng Precision provide optical quality on my plastic parts?

A
Yes. We combine the machining capabilities of the best combined 3-axis, 4-axis or even 5-axis CNC milling machines. We also have adopted the latest diamond machining technology in ultra-precision manufacturing. This is a technique called Single Point Diamond Machining (SPDM or SPDT) that can match the ability of 5-axis micro-milling to produce a range of lens and light guides types of excellent optical quality in an array or freeform pattern. With the rich polishing experience, we can get amazing appearance on both inside and outside of the parts, providing fully support to clear and optical prototype development projects.
Q When should I use machining versus injection molding?

A
Before making the investment to have injection-mold tooling made or high-volume machining processes, you likely will want to test a part that is as close to the production part as possible. CNC machining is the best option for this situation.

Additionally, engineers often need just one or maybe a few parts for test fixtures, assembly jigs, or assembly fixtures. Machining is the best option here as well, but traditional machine shops often charge a significant non-recurring engineering (NRE) charge for programming and fixturing. This NRE charge often makes getting very small quantities not affordable. The automated CNC machining process eliminates the upfront NRE costs and is able to offer quantities as low as one part at an affordable price and get parts in your hands in as fast as 1 day.
