STIER launches PolishV radial compliant spindle, highlighting high torque, precise force adjustment, and automatic tool change

STIER has launched the PolishV series radial compliant spindle, highlighting three main advantages: high torque, precise force adjustment, and automatic tool change, as a plug-and-play end-effector solution for robotic compliant grinding. Its output torque can reach over 2.7 N.m, and the floating torque can reach up to 24 N.m; the DN80 specification can replace conventional electric spindles with an outer diameter of 100 mm or even larger torque classes. It uses a pressure regulating valve to control floating pressure, providing 360° circumferential floating and ±5° oscillating radial force, with floating accuracy of ±1 N. It supports automatic tool change in conjunction with a robot tool magazine and is compatible with ER series collets.
