The belt driven cartridge spindle is oil-filled but it looks like your machine does not have a cartridge spindle. Many grinders have oil pockets for oiled ways, I believe your grinder does not have this. Some older motors have a screw at the shaft bearings where you add a few drops of oil every few years. I don't know if your motor has that.
A horizontal spindle grinding machine with reciprocating table, shown in Fig. 41, is the most common grinding machine. The horizontal spindle provides the primary motion ( C motion).
This spindle design is being applied to new machine-tool concepts and existing standard machine tools with asynchronous motors, automatic spindle change, high torque and high speed. Spindle units with coupled motors do offer a flexible approach to design, thanks to the method of connection (fig.3).
Grinding Machine Definition: A grinding machine is a production machine tool used in the manufacturing industry in which the grinding wheel is attached in the tool post and the workpiece is fixed to the work table and when the operation starts it removes the unwanted material to get the desired surface finish, correct size, and accurate shape of the workpiece.

GRINDING. MACHINE GRINDING • Grinding is the process of removing metal by the application of abrasives which are bonded to form a rotating wheel. • When the moving abrasive particles contact the work piece, they act as tiny cutting tools, each particle cutting a tiny chip from the work piece. • The grinding machine supports and rotates the grinding abrasive wheel and often …
Since the grinding process creates significant heat, many grinding motor-spindles come with a through coolant system. How to choose. When choosing between grinding motor-spindles, be sure to determine the rated power (kW), rotational speed (RPM) and rated torque (Nm) for your grinding machine.
