W stroke – variants and applications

We have seen how the ran ran W constitutes one of the most effective methods for the approximation of the parable from the spherical surface. Let's examine a few variants of this technique to increase or decrease the influence of processing in some sectors of the surface. The constant and linear displacement assumes W , orthogonal to the direction […]

Strokes “W”

Puree with   racing to “W”  is the main     technique used during parabolizzazione. Normally you run   with mirror above and tool under  , It can also be applied in some cases reversed positions with      . The position of the hands is   the one with the Palm that leans and pushes the edge to "hours 8:20e with your thumbs point towards the Centre to […]

Analysis of strokes 1/3D c.o. c. (Everything you need to know who does not stop at the "come and go" of the glasses)

Puree 1/3D c.o. c, aka racing back and forth centered (i.e., Halter: “Center over center”), abrasive machining, amplitude equal to one third of the diameter mirror, that glass is used to create a mirror scratching (such as parabolic) is, together with the patience, THE WINNING UNIVERSAL. Like the: New life gained […]

Stroke 1/3 COC

DESCRIPTION the passata with rides 1/3 center over center ( abridged: COC = “Center Over Center” ) is the classical stroke, the most widely used because it can be applied in all stages of processing both with the mirror over and tool, than vice versa. The position of the hands is the one with the Palm that leans and pushes […]
