Innovative workholding solutions help you hold onto productivity and profit in a machining process. Five new ideas show the value of creative clamping and fixturing.
Read MoreFlexibility Is A Vise
The ubiquitous table vise is more than a fixture in metalworking shops. It's a necessity. Like the machine tools they attach to, metalworking vises have had their share of technical advances aimed at extending the flexibility of these popular workholders.
Read MoreOne Insert For More Operations
Conventional wisdom about standard milling operations has always been that compared to square shoulder cutters, lead angle cutters are easier on the spindle, can be run at higher table feed rates, and cut freer. Finishes are typically better and, with the addition of a wiper flat insert, finishes could be further improved. Due to the chip thinning attributes of this type of cutter, actual table feeds can be more rapid, albeit at the sacrifice of some depth of cut compared to a zero lead cutter.
Read MoreWidening Range Of Grooving Tools
Traditionally, a grooving tool grooves, a facing tool faces and, of course, special tools do special cuts. Improved insert manufacturing technology and toolholder design is changing this tradition, allowing specialized tooling to be used more generically in a wider variety of metalcutting applications.
Read MoreSuccessful Application Of Ceramic Inserts
Applying ceramic inserts is not a simple substitution of one cutting tool material for another. There are significant process considerations that shops should examine carefully in order to realize performance and tool life expectations from ceramic inserts. Here's a look at some of the ways they are used.
