Modular Tooling System for High Efficiency

Thanks to its precision and rigidity, the modular tooling system from Paul Horn GmbH offers a high degree of flexibility for adaptation to different machine types. Standardised modules bridge several interfaces at the same time.

The modular system has a selection of tool holders for turrets and other tool carrier interfaces based on common machine types. The matching grooving tool holders with integral coolant supply allow height adjustment of the cassettes and their mounting in the normal or overhead position, on the left or right of the holder.

For multi-spindle autos, height-adjustable tool carriers are available onto which the cassettes are screwed directly. The cassettes serve as an adapter for numerous Horn grooving insert systems. Parting off, grooving, sliding-head turning: the modular system can be flexibly adapted to the application.

Horn is adding further variants to the modular system especially for use on Schütte machines. The type 850 tooling system supersedes the system 849. Of more compact size, the holder offers high stability as well as targeted cooling of the flank and rake face.

The holder system is suitable for all sizes of the 315 insert system. For other inserts, HORN offers corresponding special solutions. The tool holders are available with and without angle adjustment. Height adjustment is simple and easily accessible from the front. The tool system is compatible with the Schütte series ECX, SCX and ACX.

Related Glossary Terms

  • coolant


    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.

  • grooving


    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.

  • modular tooling

    modular tooling

    1. Tooling system comprised of standardized tools and toolholders. 2. Devices that allow rapid mounting and replacement of tools. Commonly used with carousel toolchangers and other computerized machining operations. See toolchanger; toolholder.

  • parting


    When used in lathe or screw-machine operations, this process separates a completed part from chuck-held or collet-fed stock by means of a very narrow, flat-end cutting, or parting, tool.

  • rake


    Angle of inclination between the face of the cutting tool and the workpiece. If the face of the tool lies in a plane through the axis of the workpiece, the tool is said to have a neutral, or zero, rake. If the inclination of the tool face makes the cutting edge more acute than when the rake angle is zero, the rake is positive. If the inclination of the tool face makes the cutting edge less acute or more blunt than when the rake angle is zero, the rake is negative.
