Fukudaco Belt-Driven Grinding Spindle

Manufacturer: Fukudaco

Overview

The belt-driven spindles from GMN are used for high-speed grinding operations. For small-diameter internal grinding, the TSI/TSP series is recommended. The TSA series is suitable for internal grinding of holes larger than the spindle body diameter. For external grinding or surface grinding with high processing loads, the TSAV series is recommended. Additionally, the TSL series is available for deep-hole internal grinding.

TSA Series

They are used for internal grinding of small, medium, and large holes. The tool interface adopts an HSK taper, making it suitable for grinding holes larger than the spindle housing diameter. Compared to the TSI and TSP series, the grinding wheel is positioned closer to the bearing, enhancing rigidity.

TSI, TSP series

The TSI and TSP series are used for internal grinding of small, medium, and large holes. The tool interface adopts either a male taper or a straight thread, making them suitable for grinding holes smaller than the spindle housing diameter. Since the grinding wheel is positioned closer to the bearing compared to the TSA series, the rigidity is increased.

TSAV Series

Used for external grinding and flat grinding. The bearing and taper rigidity are greater than those of the TSA, TSI, and TSP series, allowing the use of larger-diameter grinding wheels.
