HGC Series

Features

The HGC series is a spindle series equipped with an automatic tool change function for grinding (mainly cylindrical grinding and surface grinding) and special processing, excluding cutting processing in machining. Demand for automation of the replacement of grinding wheels used in grinding is also increasing, so we will design and manufacture according to the specifications required by the customer. This series can be equipped with an auto balancer and AE sensor upon request.

Production examples

	HGC 210g-10000/30
Maximum rotation speed [min ^-1 ]	10,000
Output [kW]	30
Rated speed [min ^-1 ]	1,990

HGT Series

Features

The HGT series is a spindle series that enables turning by adding a shaft lock mechanism in addition to grinding (mainly cylindrical grinding and surface grinding) except for cutting machining.

Special Options

Hydroviscous Damping (HVD) function

A typical spindle with a constant pressure preload structure applies preload to the bearing with a spring via a ball cage with a sliding function that is located on the outer periphery of the rear bearing, but the HVD spindle uses a special two-layer structure with an oil circulation chamber and a sliding function.

This has the effect of improving the damping of the natural frequency, increasing the natural frequency by suppressing the amount of preload on the bearing and improving dynamic rigidity in the axial and radial directions (reducing compliance).

In addition to the conventional oil/air lubrication device, frequency converter (inverter), and cooling device, the system configuration uses an external hydraulic adjustment unit (sold only as a set with the spindle) to control the HVD.

Please get in touch with us regarding a spindle series that can be equipped with HVD.
