Micro-Boring Bars Resist Wear
Citco PCD micro-boring bars from Fives feature a tungsten carbide body and PCD grade to optimize performance. According to the company, the tools feature cutting edges that stay sharp longer during machining of abrasive materials or precious metals. Designed for precision medical applications, the micro-boring bars are available with minimum bore sizes as small as 0.45" (1.14 mm). Fives says the tools yield improved surface finishes, deeper cutting depths and longer diameter-to-length ratios.
The right choices in tooling and technique can optimize the thread turning process.
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.
Reducing cutting fluid use offers the chance for considerable cost savings. Tool life may even improve.
