Frequently Asked Questions

1、What kinds of parts are suitable for your Swiss type lathes?

Our Swiss type lathes are ideal for small-diameter, long, and high-precision parts, such as medical implants, aerospace pins, micro shafts, watch parts, and automotive precision components.

2、What is the difference between a Swiss lathe and a traditional CNC lathe?

Unlike traditional lathes, Swiss type lathes use a sliding headstock and a fixed guide bushing, allowing the material to move close to the cutting tool, reducing deflection and achieving extremely high precision for slender parts.

3、What is the machining accuracy of your Swiss lathes?

Minnuo Swiss type lathes achieve positioning accuracy within ±0.002 mm, and surface finish up to Ra0.2μm, perfect for ultra-precision industries like medical and electronics.

4、Can you recommend a suitable Swiss lathe if I only have a part drawing?

Of course! Minnuo’s pre-sales engineers will recommend the right Swiss type lathe model within 10 minutes after reviewing your part drawing. For full production line setups, we can offer detailed solutions within 5 working days.

5、Can the Swiss type lathe be customized for specific processes?

Absolutely. We offer customizations including spindle power, number of live tooling positions, back working capabilities, guide bushing types, and bar feeder integration to meet your special production needs.

6、How is the quality of your Swiss type lathes guaranteed?

We use high-quality hardened steel structures, high-precision spindles, and all machines undergo thermal stability tests, geometric precision tests, and full trial machining before shipment.

7、What is the delivery time for Swiss type lathes?

Standard models can be delivered within 20–25 working days. For customized configurations, delivery times are typically 30–45 working days.

8、What after-sales service do you provide?
