Leitz HSC technology: Maximum performance and more profit for you. 25% higher cutting speed 25% higher RPM Up to 40% higher feed rate 35% reduction in machining time Cutting speed vc [m/s] 120 110 100 90 80 70 60 50 40 Traditional design Turnover per year [T ] 2800 2600 2400 2200 2000 1800 1600 Shrink-fit technology HSK Shrink-fit arbor for boring tools and shrink-fit chuck for shank tools Through a special mounting method, the tools are clamped securely without any play. On arbors Tool changing in the machine is possible. This process reduces the interface tolerance to zero and therefore the balance and run out can be accurately controlled. The toolset rigidity is now as close to a monobloc construction as possible. Due to this technology, higher RPMs and feed can be achieved resulting in a constant finish quality. The knives can be fitted and removed from the tool while the toolset is in position. Mounting shank tools into a ThermoGrip shrink-fit chuck Using this clamping technology, high running accuracy, balance and the dynamic stability of the tools are achieved. The tools are then suitable for very high RPMs, also for HSCmachining (High Speed Cutting). The Leitz shrink-fit clamping technology provides maximum stability, accuracy and thus arriving at the preconditions for an optimal finish quality and with the longest tool life.

Tool technology from Leitz: Technology at the edge enables the best efficiency. Tailored for every customer demand. The combination of tool systems ProFix and ProFix C (regrindable) together with the knife systems ProfilCut and ProfilCut Plus is an economical, tailored solution for all customer demands. Aluminium alloyed tools: Lower mass for more performance. Balanced and thus optimized finish quality. Reduced stress and wear on the machine bearings. Quiet running through optimized tool body design. Accurate tool mounting. Easy handling. Thread security with Heli-Coil steel inserts. No corrosion on the tools. Hard coated alloyed tools for the most demanding conditions. Reduction of tool body wear especially during the machining of abrasive work pieces. New solid tungsten carbide spiral drills: Fast, clean, accurate. In comparison to traditional tipped drills, feed rate is increased by 30 50%. Precise dowel fitting from the resulting accurate bore. No chipping on the bore entry. Low power consumption through optimal chip ejection. Precise plunging on bevelled faces and mitred areas due to unique centre point geometry. New coated router cutters: Efficiency from the beginning Reducing working steps due to roughing-finishing in one pass. Increased productivity through higher feed speed. Increased tool life due to the special coating. Reduction of the process costs. 3
Leitz Chip-Technology: With intelligent tools, save set up time by 71%. Maximum operator safety through easy handling Reduction of the setup costs Significant increase in productivity Risk free of tool and machine collisions. For the application on CNC-machines, Leitz provides intelligent tools with an integrated memory chip. This provides the machine control centre essential geometry and technology data such as tool length, diameter as well as RPM and direction of rotation. The risk of false manual input is reduced as the micro chip in the tool automatically updates the machine. E.g. for resetting the tools for different window types. Through intelligent Leitz tools, the incorrect use of the tool is eliminated therefore high working and process safety is achieved. Automatic radius offset correction after sharpening prevents producing an incorrect profile, thus reduces scrap costs. 4
Leitz RipTec procedure: More profit in all sectors. Reject quota nearly zero 30% increase in tool life 30 % increase in feed rate Significantly improved product quality Problem: Tear outs on the surface Solution: Pre cutting with ripple profile Extremely strong joints Very few tear outs during the cut exit due to the RipTec cutting geometry Ripple technology for the planing process Through the ripple technology for surface machining on top and bottom, a Leitz innovation, an optimal finish is achieved on the workpiece. This is also true for spiral grain and pre cut wood. Through this technology we have minimised the reject quota for planing parts. Moreover the lifetime of the tools are increased as they can be resharpened up to 20 times. Leitz RipTec for cross grain cutting (S+T and counter) Through this technology, tear outs on the face side during cutting are avoided. Due to this enables the possibility that the feed speed of the tools can be increased considerably, therefore increasing the machines productivity. With the ripple profile small glue bags are created, this results in a considerably more stable corner joint over traditional profiling. The lifetime of the tools are increased by 20-30%. Ripple technology for cutting along the grain Longitudinal machining, rippled and straight knives alternate in one tool. Therefore with just one pass, the tool is pre and finish cutting, resulting in an excellent surface finish quality. This specifically is used for the sensitive areas of the window, i.e. on the overlap. Through this technology chip impacts are avoided, which often present a problem for example, during the machining of the glazing bead. The costs are reduced by 50% as the ripple knives only have to be changed with every third planer knife.
