Claimed to be Australia’s largest manufacturer of rotary shank cutting tools, Sutton Tools, has gained market share in the competitive aerospace industry by producing superior tools using the linear motor technology on ANCA’s MX7.

To gain traction in the aerospace market, Sutton’s needed to push the boundaries of what could be expected from tool machining materials in the aviation industry.

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 are now consistently achieving a longer tool life and faster cycle times in some of the higher strength materials such as titanium, which is a great result.

“With our new MX Linear machine, we have seen dramatic improvements in the surface finish of the cutting tools. This change has been achieved by moving away from the traditional ball-screw movement on machines to a linear motor. We conducted a direct comparison as we have ANCA ballscrew grinders and have also experimented with different grinding wheel grades and grinding parameters to ensure we are achieving the best possible finish.

“A better surface finish has also meant 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. It makes their day easier!

“A company in France had been buying a competitor's brand but we saw an opportunity to make a better product and win the business. After studying surface roughness of a tool, we felt that the linear motor could achieve a higher accuracy of surface finish. We conducted some tests and found that was exactly what we could achieve and now we have a tool that performs better than our competitors.

“To validate our grinding methods, we use an optical 3D scanning technique to measure the area surface roughness on the rake face and the cutting rake on the tools. This means we can manage our quality levels to a level of accuracy which is world class in the industry,” concluded Boyd.
