Paul Horn GmbH has never stopped developing and optimising its product portfolio. At the same time, it has integrated almost 100 percent of the added-value creation into its own production. The range of applications of the tool systems has grown considerably. Today's machining operations across a diverse range of materials constantly demand further development and adaptation of the tool systems. Grooving with indexable inserts has become indispensable in modern production. Radial grooving, parting-off, axial grooving and internal grooving to micron precision are now part of everyday life in industry. For such machining processes, Horn relies on the S224 insert system, among others.
Horn has revised the clamping of the S224 type indexable insert for use in Swiss-type lathes. In order not to have to remove the holder for indexing or changing the insert, the Horn engineers relocated the clamping screw to the side. Clamping now takes place via a camshaft. This allows the insert to be clamped quickly at either side of the holder without having to remove it. Furthermore, this type of insert also eliminates the need to invest in special quick-change systems. For the user, in addition to simple operation with a torque wrench, there is the advantage of reduced machine downtime due to faster set-up. Horn offers the holder system from stock in left and right versions as a 16 mm x 16 mm square shank. All variants of the holder are equipped with an interface for internal coolant supply from above and below.
Related Glossary Terms
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.
- indexable insert
Replaceable tool that clamps into a tool body, drill, mill or other cutter body designed to accommodate inserts. Most inserts are made of cemented carbide. Often they are coated with a hard material. Other insert materials are ceramic, cermet, polycrystalline cubic boron nitride and polycrystalline diamond. The insert is used until dull, then indexed, or turned, to expose a fresh cutting edge. When the entire insert is dull, it is usually discarded. Some inserts can be resharpened.
Measure of length that is equal to one-millionth of a meter.
Main body of a tool; the portion of a drill or similar end-held tool that fits into a collet, chuck or similar mounting device.
