Absolute Machine Tools presents Nexturn Swiss CNC lathes engineered to maximize accuracy and economy in the production machining of complex precision parts. Nexturn lathes include basic guide-bushing-equipped machines with maximum bar capacities from 12mm to 38mm diameter; removable guide-bushing machines from 20mm to 38mm capacity, and non-guide-bushing machines with 26mm to 51mm bar capacity. In addition, Nexturn provides turret-type non-guide-bushing sliding-headstock machines to process 45mm, 56mm and 67mm diameter bars.
Six different lathe series are designed to meet specific production and economic requirements:

Most models feature different levels of sophistication and options that enable machine capabilities to be tailored to fit any budget.
Nexturn Swiss Lathes are available with the Servo Learning Oscillation option. The main purpose of Servo Learning Oscillation is to eliminate long, stringy chips from gathering around the part and cutting tool during the machining process. By constantly changing frequencies through the X, Y, and Z axes combined with interrupting cutting on the part, the chips will break away clean allowing for continual flawless cutting.
Swiss machines have a small work area, which can make chip ejection a common problem. Chips tend to get entangled around the part or the tool, which can increase cutting resistance, increase cutting heat (causing built-up edges), cause surface damage and scarring, damage the cutting tool, and clog the tool flutes, all of which are undesirable effects.
Applying this feature during the cutting process is how the phrase “Breaking the Chip” was born. The Servo Learning Oscillation feature on Nexturn Swiss CNC lathes is best used on any hard-to-machine materials including aluminum or stainless steel.
Benefits of the Servo Learning Oscillation Feature include:
- Increased Productivity: prevents chip problems such as hanging chips & birds’ nests, so your machines can operate continuously with no operator intervention ultimately leading to reduced production time overall
- Ideal solution for problems such as chip entanglement & built-up edges in hard-to-cut materials like Inconel, surgical stainless, and copper
- No additional hardware needed (just software)
- Accuracy of the part is not compromised
- Stable part quality
- Improved tool life & reduced equipment costs
