Past 1 / 3D c.o.c, alias the forward-backward centered race (or, all’americana: “center over center”), processing for abrasion, amplitude equal to one third of the mirror diameter, in which scratching of the glass is used to make a mirror (for example parabolic) is, with patience, UNIVERSAL WINNING WEAPON. Like the: The acquired new life
This post is meant to give information for groped to make things easier when trying to make the tool into pitch, necessary for the Bi phase and polishing parabolizzazione. Generally, when it is explained how to make the dough for the tool, there are hardly indicated the precise percentages for ingredients, but generally
DESCRIPTION La pass with racing 1/3 center over center ( shortened: COC = “C. o. c.” ) is the classical stroke, the most widely used because it can be applied in all stages of processing both with the mirror above and below the tool, than vice versa. The position of the hands is the one with the palm that supports and pushes
Aspect not to be overlooked during the whole manufacturing process is cleaning the workplace. This need, that in each processing of materials can be an important aspect not to be underestimated, here becomes crucial, since we are dealing with different abrasive grits. What it makes indispensable a perfect cleaning
DESCRIPTION The past is the chordal excavation technique more aggressive and effective towards our mirror. In fact it allows to remove a large amount of material in a shorter time compared to the other past. On the other hand is a technique that does not allow to obtain a regular shape, It should therefore be used only in the initial stages of blanking and up
When in processing a mirror you will reach a refined and smooth surface with abrasives in grain 800 or outside, You must establish for preparing the tool with pitch patina coverage, to proceed in the following two important final processing stages, that are the transformation of the frosted surface but opaque, in
