Anca Improving chip evacuation and tool performance
According to the company, Anca’s Linx cylindrical linear motor ensures rigidity to deliver a superior finish on cutting tools every time achieving a surface finish roughness average as low as 0.16 Ra. Find out, how you can achieve a superior tooling surface finish with Anca's tips.
As well as being pleasing to the eye, highly polished flutes and gash surfaces improve chip evacuation and significantly improve tool performance and life. The smoother surface enables swarf (or chips) to exit more freely, preventing chip packing and material build up during machining.
Anca is well known in the industry for its rigid grinding machines and has combined this with its sister company, Anca Motion’s, LinX linear motor technology. Tools ground on their machines have a consistently high-quality cutting edge and surface finish, the company says. According to Anca, customers have reported dramatically better results using the duel technologies since the product was launched.
Cylindrical linear motors boast smooth axis movement
Simon Richardson, Anca Product Manager explained: “When machining softer or ductile materials, chips can stick to the carbide. If the chips created are not removed faster than they are being produced - the tool may not perform effectively. However, a better surface finish on the flute prevents the swarf from sticking onto the flute face of the tool while reducing the amount of heat that is generated when machining.”
“We realised that having a highly rigid machine with a cylindrical linear motor that boasts a smooth axis movement, would greatly improve the final surface finish on the tool. The research and development team conducted many hours of test grinding to rigorously test our assumption of what surface finish quality we thought was possible.”
An Alicona infinite focus XL metrology machine in Anca’s Grinding Centre of Excellence was used to verify the results to Nano metre accuracy finding that a surface finish roughness average as low as 164.7nm (which translates to 0.16 Ra) was achieved.
Paul Bocchi, General Manager of Anca Motion said: “An advantage of knowing Anca’s customers so intimately is that we could immediately see how our technology would work seamlessly to improve performance.”
“The LinX cylindrical linear motors ensure there is no loss of preload or rigidity when grinding tools. As well as that, reversal errors are eliminated and higher contouring accuracy can be maintained due to a control algorithm we use which is unique to Anca.”
