Is .060” enough material to clamp on my part while machining?

.060” is enough for most applications if the bottom of the material has only a small edge break or corner radius of up to about .030” max. All parts shown in the videos on our web site, were machined gripping on only .060”. However if the edge condition of the material is rounded very much, it might not be enough. Also softer materials like some plastics and non metals may need more than .060” of grip height to be gripped adequately. More grip height can be achieved by removing the grips, stops and their screws from the jaws, clamping the vise tight and machining off up to .015” of material from the top of the jaws. This will allow the grips to stick up higher than normal and grip more material. No more than about .015 should be removed as the grip geometry will only allow gripping on about .075” max.
