Oct 01, 2016 the precision freeform grinding depends on the on-machine truing of diamond wheel, leading to the inefficiency of grinding system. hence, a virtual ball-end algorithm along with a fixed tool posture angle is proposed for the 5-axis grinding of glass by using a self-dressing diamond.
Polishing machined aluminum to a mirror finish: this is one of many strategies to get aluminum to a mirror finish. if you have sandpaper, a buffing wheel, and some compounds, you can get pretty close to mirror. to get clearer and clearer finishes, you can chrome plate, electro-polish, or do it.
