LATUMA We have done some test in the USA with our new L-coating with good results in material such as G-X6CrNiMo1810 (CF8M). This new L -coating can work up to 100°C higher temperature than our R-coating. It is the need to further boost productivity in processing and deploying a wide variety of challenging materials while improving process reliability even under the most difficult circumstances. Benefits with L -coating: • The high aluminium content enhances oxidation resistance and hot hardness. • The balanced coating hardness versus residual stress ratio opens up a broad spectrum...

QuadCut - Threading the ingeniously simple way QuadCut is an entirely different type of threading tool. Instead of the traditional horizontal triangular insert, this insert is positioned upright and it has a square shape. The benefits are obvious: 1. The insert is much stronger. 2. The insert mounting is much more stable. 3. The insert has four cutting edges instead of three. QuadCut offers maximum indexing accuracy, with support points strategically located. The QuadCut system has very high indexing accuracy. This is principally due to a combination of: 1. The insert is being precision...

Technical information QuadCut - Threading the ingeniously simple way The slender toolholders for breadth of range THREADING TOLERANCES The threading operation must often be carried out in confined spaces, such as at workpiece shoulders or close to the chuck in bar automatics. In these situations, you can use the ”blade toolholder”. The QuadCut insert is mounted upright and we can make the toolholder no more than 6 mm wide - with unimpaired stability. This is invaluable in confined spaces. All thread standards have dimensional tolerances to achive the required fit between the shaft and the...

Technical information Technical information CLEARANCE ANGLES RADIAL INFEED FLANK INFEED MODIFIED FLANK INFEED ALTERNATING FLANK INFEED This is the most common method of in-feed on short chipping materials. On long chipping materials it is difficult to break or control the chip as it shears from the flanks of the thread. The high heat generated from this method of in-feed on the tool nose radius causes premature tool failure. Angular in-feed programmed at the same angle as the thread flank. Although the heat generated from this method is greatly reduced, the rear flank of the insert removes...
