ABSTRACT:
A machine tool vise is provided with a set of soft jaws. The soft jaws attach inside and against two master jaws. Both jaws of the vice are equipped with an alignment mechanism to position the soft jaws to assure repositioning. Each jaw is provided with a lenthwise slot which provides a registration face at right angles to an upright registration face at the master jaw. The soft jaw is provided with a bracket that registers on the two faces just mentioned to obtain precise repositioning in two dimensions. Positioning in the third dimension is accomplished by use of a registration pin joining the soft jaw to the master jaw, and a tapered set screw threading into a chamfered opening is used along with the pin to accomplish clamping, thereby assuring complete registration of the bracket holding the soft jaw in the vice. The soft jaws can be mounted, removed and later returned with assurances that the soft jaws are held at a fixed location with respect to the cutter and spindle supporting the cutter. This overcomes errors in and assures parallelism between the cutter and the work piece ultimately supported in the soft jaws.
