Tungaloy Corp. announces the expansion of TetraForceCut, the grooving tool series with four-cornered inserts: the STCR/L-CHP toolholder with a coolant hole for high-pressure internal coolant supply. (Max. 2,000 psi.)
The new STCR/L-CHP toolholder delivers ample coolant to the optimal position of the cutting edge through the coolant hole, achieving stable and long tool life. While improvements will be seen with normal pressure coolant, the STCR/L-CHP toolholders will show more significant chip control and removal with high pressure coolant, according to the company.
Main features:
■ The STCR/L-CHP toolholder has an internal coolant hole and works for coolant supply both in normal and high pressure.
■ Stable coolant supply to the optimum position on the cutting edge.
■ Coolant inlets are located at the lower jaw and the back end of the toolholder, either of which can be used according to the machine specification.
Fluid that reduces temperature buildup at the tool/workpiece interface during machining. Normally takes the form of a liquid such as soluble or chemical mixtures (semisynthetic, synthetic) but can be pressurized air or other gas. Because of water’s ability to absorb great quantities of heat, it is widely used as a coolant and vehicle for various cutting compounds, with the water-to-compound ratio varying with the machining task. See cutting fluid; semisynthetic cutting fluid; soluble-oil cutting fluid; synthetic cutting fluid.
Machining grooves and shallow channels. Example: grooving ball-bearing raceways. Typically performed by tools that are capable of light cuts at high feed rates. Imparts high-quality finish.
The development of a cutting tool that optimizes performance during vibration cutting is a game-changer. NTK offers the ultimate solution, eliminating the uncertainty in tool selection.
