To gain traction in the aerospace industry, Australian manufacturer of rotary shank cutting tools, Sutton Tools, has been using linear motor technology. Contributed by Anca.
Jeff Boyd, export manager at Sutton Tools said, “By really focusing on how we could improve the surface finish, and with the added capabilities of the linear motor, we have created a product that is delivering significant productivity gains for our customers. The team is now consistently achieving a longer tool life and faster cycle times in some of the higher strength materials such as titanium.”
Mr Boyd added that improvements in the surface finish of the cutting tools have been achieved by moving away from the traditional ball-screw movement on machines to a linear motor. The company also conducted a direct comparison and experimented with different grinding wheel grades and grinding parameters for the best finish.
“A better surface finish has also mean we get better adhesion of the coating and stable performance to the cutting tool which is important for our customers. Tool stability is important because it means our customers can confidently forecast their production schedules and reduce machine down time,” said Mr Boyd.
In order to validate their grinding methods, an optical 3D scanning technique is used to measure the area surface roughness on the rake face and the cutting rake on the tools.
Anca has combined linear motion motor technology from its sister company Anca Motion to its own rigid grinding machines. The LinX cylindrical linear motors prevent loss of preload or rigidity when grinding tools and reversal errors are eliminated and higher contouring accuracy can be maintained due to a unique control algorithm.
