Inserts Add Flexibility to Grooving Tool Line
Tungaloy is growing its TetraMini-Cut grooving tool family by adding items to its TCG18 insert lines. Compact and offering economical, four-edged geometry, the line incorporates a rigid insert clamping system that provides indexability and accuracy, extending insert life.
The company is adding 40 inserts to its line, covering a wider spectrum of workpiece profiles, materials and machine setups ranging from small and miniature parts in Swiss-type machining to general-lathe grooving and threading applications. The inserts are available in AH7025, a dedicated grooving grade optimized for resistance to chipping and plastic deformation. This grade is designed to provide secure performance and high metal-removal rates in demanding operations.
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.
Cutting holes by interpolating a face milling cutter may be a better process choice for many rough and even finish boring operations. Software improvements and better cutter designs allow expanding use of the versatile face mill for hole making.
Liquid coolant offers advantages unrelated to temperature. Forced air is the fluid of choice in this shop...but even so, conventional coolant can't be eliminated entirely.
