Launched at the recent EMO Hannover 2019 event in Germany, ANCA’s GCX Linear builds on the best aspects of its proven technology to offer a purpose-built solution for manufacturing and sharpening skiving cutters. With a five-axis CNC grinder powered by LinX linear motor technology on X, Y and Z axes, the GCX Linear also comes with features specially designed for skiving cutters and shaper cutters.
“ANCA is responding to the increasing popularity of skiving and resulting surge in demand for skiving cutters. We want our customers to have a complete solution for manufacturing and sharpening skiving cutters and the GCX Linear will set the new benchmark for skiving cutter grinding,” said Xiaoyu Wang, product manager at ANCA.
Dressing the complex wheel profile is critical, so ANCA developed the latest acoustic emission monitoring system (AEMS), according to Wang.
“AEMS can be taught to pick up the right sound of perfect dressing even in a noisy production environment. Built upon supervised machine learning algorithm, AEMS ensures the wheel profile is dressed within micron accuracy with the least possible time while minimising the reduction in size,” said Wang.
One of the key features of ANCA’s new GCX Linear is the patent pending Motor Temperature Control (MTC), which minimises machine warmup time, and delivers optimal thermal stability during grinding. Smart control algorithm actively manages and maintains the temperature of motorised spindles in the GCX Linear. Benefits delivered by this feature include reduction in machine warmup time—you can start grinding tools sooner, knowing the machine has reached thermal stability—thus improving productivity and machine utilisation.
It also features consistent thermal stability of the spindle over time regardless of changes in spindle load or speed, or spindle cooling coolant temperature. This greatly improves dimensional stability of grinding results.
ANCA’s GCX Linear is powered by its LinX, a linear motor technology for axis motion (X, Y and Z axes). In conjunction with linear scales, LinX helps GCX Linear achieve superior precision and performance. Specially designed for a lifetime of operation in harsh grinding environments, the LinX motors have a cylindrical magnetic field, which means there is no additional down force on the rails or machine base.
With no temperature variations—therefore, there is no need for a separate chiller unit—and being sealed to IP67, there is minimal wear and tear, thus machine accuracy remains over its lifetime. The LinX linear motor has higher axis speed and acceleration, leading to reduced cycle times while maintaining a smooth axis motion.
