Linear Motor Ensures Smooth Axis Movement for Tool Grinders
ANCA Motion’s LinX linear motor technology is designed to provide manufacturers the toolmaking capability to produce highly polished flutes and gash surfaces to improve chip evacuation and aid tool performance.
ANCA Motion’s LinX linear motor technology is designed to provide manufacturers the toolmaking capability to produce highly polished flutes and gash surfaces to improve chip evacuation and aid tool performance. The smoother surface enables chips to exit more freely, preventing chip packing and material buildup, for example, when machining softer or ductile materials.
According to the company, a highly rigid machine with a cylindrical linear motor, such as the company’s MX7 grinder, assures smooth axis movement, improving the final surface finish on the tool.
The motor ensures no loss of preload or rigidity when grinding tools, and ANCA’s control algorithm eliminates reversal errors and maintains accuracy, according to the company. The company claims that this technology enables grinding to an average surface finish roughness as low as 164.7 nm (0.16 Ra).
Roughing and finishing on a single machine, using a single setup, has appeal for most shops. The advantages in time savings and accuracy are obvious. Eliminating the transport of workpieces between machines, as well as the setup for those secondary operations, is a boon for throughput. Critical features that need to maintain dimensional relationships can be much more reliably produced if machined complete in one clamping.
Advanced grinding equipment gives this shop the flexibility and automation it needs to serve customers with either rapid-response or high-volume jobs.
Two enabling technologies -- superabrasive wheels and high precision servo control -- come together to provide a contour grinding process that resembles an OD turning operation. For many medium volume OD grinding applications, this method may be a means to consolidate several manufacturing steps into a single setup.
