Iscar Launches HPC Turning Tools
For the first time, a complete line of standard tools for High Pressure Coolant (HPC) turning puts more efficient turning of titanium, Inconel and stainless steel within easy reach of any shop. Previously, HPC tooling was available only as a special. Manufacturers can now get the same quick delivery and security of supply for HPC tools as for any standard tool. In combination with optional standard high pressure plumbing readily available on virtually all mainstream turning machines, Iscar JETHP (Jet High Pressure) tools bring three key benefits on these problematic metals. They consistently end chip jamming, improve tool life more than 10 to 1, while doubling removal rates.
HPC turning has been proven effective for decades as a stable, safe process, especially on titanium. The obstacle has been that it required custom coolant plumbing and special tools. More recently, most machine builders have made high pressure coolant plumbing capability a standard option. Iscar has completed the HPC chain by standardizing the tooling as well and making it as easy to use as regular tooling. The Iscar JETHP family covers the full range of turning, grooving and parting tools and includes HPC versions of the company's ISOTURN, HELITURN, TANG-GRIP, PENTACUT and CUT- GRIP tools, in both standard and interchangeable-tool CAMFIX styles. Their design derives from more than a decade of Iscar experience in supplying special HPC tooling to hundreds of manufacturers, mostly titanium fabricators.
All styles feature internal coolant paths compatible with through-spindle plumbing in the machine. The JETHP line also includes all connection accessories as standard. HPC turning works by aiming a high pressure "hydraulic wedge" of liquid coolant precisely into the cutting zone, shattering chips into uniformly small, classic C-shapes and ejecting them completely out of the way. In addition, because it remains liquid at such high pressures and flow rates, it lubricates and cools the cutting area more effectively. Between 40 and 400 bars pressure, the higher the pressure, the smaller the chip in titanium, Inconel and long-chipping stainless steels.
In the Iscar ISOTURN line, two separate streams simultaneously deliver coolant to the top rake and bottom flank of the tool. The nozzle for the top stream can be aimed and uniquely, is easy to move out of the way for convenient insert indexing and replacement. It automatically snaps back into place when coolant is turned back on. The bottom stream can be turned on to enhance the cooling effect. Other models in the line have discharge points, always targeting the cutting zone.
