Basics of Grinding - Manufacturing

grinding machines perform the dressing task automatically. The application of coolants to the grinding process is important. Coolants reduce grinding machine power requirements, maintain work quality, stabilize part dimensions, and insure longer wheel life. Coolants are either emulsions, synthetic lubricants or special grinding oils. Coolants are applied by either flooding the work area or by high pressure jet

Jan van Gastel: Making a mirror-o-matic mirror making machine

On the picture below the machine is fine grinding an 8 inch mirror with an 71% tool (143 mm diameter) and 9 micron aluminium oxyde. The bent lines on the mirror are the effect of the tool turning - with respect to the mirror - faster at the central part of the mirror as compared to the edge zones. The speed of the turntable is 45 rpm here, but I use speeds up to 80, sometimes even 100 rpm for fine grinding
