The RH Series is engineered with a sharp focus on precision, providing a superior solution for grinding mass-produced workpieces as well as one off pieces. It's particularly suited for arts where uniform parallelism and a high-quality surface finish are essential. The continuous rotation of the table permits higher table speeds. The result is a consistent, unidirectional grinding motion that ensures a smooth and fine finish on every piece.
This rotary-table machine with horizontal wheel spindle can be applied to any job, for cutting steps and profiles.

RH Series: Reinventing Precision with Every Revolution
Alex rotary table grinders feature a mechanically driven circular table supported by precision scraped flat ways and a center bearing completely free from play.
Since the Rotary table only carries out a single movement and because in-feed and cross traverse are produced by the wheel, these machines achieve highest possible accuracies combined with shorter grinding times.
The transverse and vertical movements of the spindle are mechanically driven, completely separate from the table rotation. We maintain an accurate 90 degree angle between all the axes during manufacture.
The various degrees of automation can be extended to fully-adaptive grinding with power-dependent downfeed for optimum yield. A fast approach device can be used to reduce the time needed to grind mass produced parts.
