You don’t have to look too hard to find a Swiss-style CNC automatic lathe to productively machine precision parts for medical devices. Parts are typically 12–20″ (305–508-mm) long, with length-to-diameter ratios of 12–15×, and machined from bar from 10 to 32-mm diameter. Outlier sizes down to 3 mm and up to 38 mm and even larger are available for specialized applications. Swiss-machined parts of these types require support with a guide bushing along their entire machining length to allow removal of a large amount of material in a single pass.Get more news about Automatic Cnc Lathe,you can vist our website!

But there are some new innovations in the marketplace that are worth a fresh look, such as advanced Swiss machine technology with a fully programmable B axis, which provides the user with capability to machine complex shapes and drill angles and mill profiles. New developments in CNC automatic lathes aren’t limited to the Swiss-type, however. CNC automatic lathes that are convertible from Swiss to fixed headstock machines (often with changeover time as fast as 15 minutes) have been introduced by leading machine builders. These machines allow machining short parts close to the headstock and save material cost by reducing the remnant of expensive ground bar that is left by Swiss machines.
When Honor Med Maskiner Corp. (Elgin, IL) was looking for a new machine to replace the company’s older equipment, it chose the Tsugami B0326-II. “We wanted a machine that was extremely versatile and could hold tight tolerances,” said Patricia Hirsch, owner. “The three most important factors that made us choose a Tsugami were the capabilities of the machine, price and support. The modular live rotary tool units, live tooling speed and the option to run without a guide bushing are just a few of the reasons why Tsugami was the best option for us,” said Hirsch.

The Tsugami B0326-II Swiss-type machine can be quickly and easily converted from a direct-drive guide bushing bar-fed operation to nonguide operation when fitted with the chucker kit option, making it well-suited for short or prismatic part machining. “The chucker option is increasingly popular for relatively short parts like hardware, fasteners, electrical connectors, and even medical parts like spinal hooks and short instruments,” said Ron Gainer, Tsugami Rem Sales (Windsor, CT).
The sweet spot in the Swiss machining market volume is the 20-mm machine, especially for medical applications where the heaviest volume is,” said Gainer. “We have a new 32-mm Swiss-type machine, the SS327-5AX model with full B axis that is convertible and can be run as a chucker. The 32-mm machine has great appeal for job shops because of the variety of work it can handle. Shops don’t want to be limited and it gives them good Swiss capability.”

For single setup solutions for complex parts, Tsugami has introduced the SS20M-5AX 20-mm multifunction machine. It features vertical machining capabilities, five-axis simultaneous control, and continuous B-axis movement. The Tsugami SS20M-5AX combines the versatility of a CNC automatic lathe with the functionality of a vertical machining center. It is capable of producing highly complex parts up to 20 mm in diameter and is equipped with a 24-tool automatic toolchanger and vertical tool spindle that performs multi-angle operation on main or subspindle workpieces.
