Schaublin Overhead Drive for Milling and Grinding Attachments The drive for the milling and grinding attachments for the Schaublin 70 and 102 lathes is provided by a 6mm round belt supported by an array of four pulleys and driven either by a separate motor as in the illustration below, or by the headstock drive unit on bench mounted open headstock machines. More recently Schaublin have adopted a column mounted motor with frequency control. Schaublin also offer the option of milling and grinding spindles featuring their own integral motor units.
