For aerospace manufacturers, CNC machine tool spindles are critical to any drilling, milling, boring, grinding, routing, cutting, or sawing process. However, when these systems deteriorate and fail due to contaminants, human error, improper maintenance, lubrication issues, or poor spindle design, a quality rebuild is often required.
Grinding. Foundry grinding spindles are designed to do just that – grind away excess metal with a grinding wheel to the desired shape or finish. The size and configuration of the spindle will vary depending on the specific grinding application and environment. Below are examples of Dynomax foundry grinding spindles.

The wheel, with its spindle and bearings, must be insulated from the machine frame and supplied with current through slip rings. The machine is similar in design to surface grinder or tool. The cutter grinder and the equipment includes a tank, filter, and pump for the supply of electrolyte, and a power unit for delivering a heavy dc current.
ELID Grinding, since its introduction over two decades ago, has helped in material removal of hard and difficult-to-cut engineering materials. A gist of the important research milestones on the process has been organized in this report. The hybrid process of ELID Grinding has a simultaneous electrolytic reaction and grinding action.
Such spindles will be transmitting far higher power (40 to over 100 hp, or 30–75 kW) than that employed in a conventional surface grinding system of similar table size. This is a major difference in precision grinding compared with abrasive machining. Precision grinding takes very small depths of cut at a fast feed rate.
Brief design and manufacture considerations are detailed for a hybrid electrochemical grinding unit adapted from a vertical machining centre using a 40,000 rpm spindle and 500 A DC generator.
Abstract A three-axis CNC grinding machine tool for the ultra-precision mirror surface grinding of advanced materials such as ceramics and other hard and brittle materials has been designed. The grinding machine is composed of the air spindle, a high-damping resin concrete bed, and a three-axis CNC controller with high resolution AC servo motors.

Electrolytic in-process dressing (ELID) grinding is a new technique for achieving a nanoscale surface finish on hard and brittle materials such as optical glass and ceramics. This process applies an electrochemical dressing on the metal-bonded diamond wheels to ensure constant protrusion of sharp cutting grits throughout the grinding cycle.
