Machine Information

Star SR-32JIII Type B sliding head lathe

The SR-32JIII Type B sliding head lathe offers best-in-class accuracy, rigidity and metal cutting performance within the 32mm diameter range.

It offers a range of enhancements over the SR-32JII including improved rigidity, upgraded swarf clearance, refined ergonomics, Step Cycle Pro chip-breaking technology and the inclusion of a sub-spindle flush pump as standard.

The 8 station back working platen with Y2 axis increases “overlapping” opportunities to reduce cycle times and increases the total number of tools that could be mounted to 39.

Flexibility has also been enhanced with the ability to switch between guide bush and non-guide bush modes. Machine rigidity has been enhanced with the adoption of dovetail slide ways on X1, Y1, Y2 and Z2 axes.

Spindle performance has been increased with more speed and power across all four spindle motors, in addition hydraulic clamping for the main and sub-spindle collets has been adopted which increases the clamping force by up to 40%.

Case Studies

Metallo Ltd Case Study

An incredible story from Metallo Ltd, a company transitioning their business and making this part on one machine instead of two. When you hear the cost of the material you'll understand the reason they needed a reliable machine to make the part to tolerance in one-hit.

Restormel Machine Case Study

In a bid to further expand their mill-turn production capabilities and keep up with increasing demand, Restormel Machine invested in the SR-32JIII Type B. The result? 24/7 lights-out production, good margins, and cost-effective solutions for customers!
