External Шлифовальный шпиндель
170MD30Y20 HC63
High-performance aсинхронный мотор-шпиндель for external/cylindrical grinding. 20 kW power at 30,000 r/min with 300mm maximum wheel diameter. Water-cooled with micron-level accuracy.
170MD30Y20 HC63 External Шлифовальный шпиндель
The 170MD30Y20 HC63 is a dedicated external grinding spindle designed for CNC cylindrical grinding machines performing высокоточный external diameter grinding operations. Мощностьed by a 20 kW asynchronous induction motor, this spindle достигает operational speeds up to 30,000 r/min, enabling high wheel surface speeds for efficient material removal and superior surface finish quality.
The spindle приспосабливается к grinding wheels up to 300mm in diameter, supporting a wide range of workpiece sizes and grinding parameters. P4 precision angular contact шарикоподшипники in a rigid preload configuration ensure consistent runout accuracy of 1 micron or less at the wheel mount, critical for achieving tight dimensional tolerances and low surface roughness values. A high-efficiency water-рубашка охлаждения поддерживает stable thermal conditions, minimizing spindle growth and ensuring consistent workpiece geometry throughout production runs. The 170mm корпус diameter and HC63 wheel mounting interface make this spindle directly compatible with major CNC cylindrical grinder brands. It is ideally suited for precision вал grinding, bearing journal grinding, and high-volume automotive component production.
