ISCAR is expanding the drill length options by adding the 12xD depth to diameter ratio, in a diameter range of 8 to 25.9 mm.
The DCN drills feature cylindrical shanks, which enable clamping of the drill in hydraulic toolholders (most recommended) or in spring collets. All drill bodies feature helical coolant holes. Prior to using the 12xD drill, it is recommended to drill a pre-hole by using a DCN 1.5xD drill or a centering drill.
The HCP drilling heads enable drilling with 12xD drills without the need for pre-hole preparation.
The drills can be used in clad plates. The 12 L/D ratio drills are commonly used in the heat exchanger and other industries.
1. Process of locating the center of a workpiece to be mounted on centers. 2. Process of mounting the workpiece concentric to the machine spindle. See centers.
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.
ISCAR has fine-tuned its workhorse GROOVE TURN cubic boron nitride (CBN) formulation to materially improve rough and finish grooving on hard ferrous materials under a wider range of conditions.
ISCAR continues to create fresh solutions for difficult ID machining problems through strategic additions to its popular PICCO family of solid carbide inserts.
With a new level of built-in asymmetry, ISCAR EC-H CHATTERFREE solid carbide endmills bring a new level of speed and process security to slotting and shoulder milling of ferrous metals.
To meet the growing demand from the energy/powergen sector, ISCAR has launched a line of extra-strength standard grooving tools for more efficient and secure machining of T and L slots so common in turbomachinery.
ISCAR has launched a line of improved CUT-GRIP grooving inserts for ID grooving that features the N-type chipformer that has proven so effective in OD turning of problematic metals.
A major expansion of the ISCAR HELIDO 845-13 mill family brings the efficiency and economy of these popular tools to a wider size and application range.
