Kistler Announces Three-Component Modular Turret Lathe Cutting Force Measurement System

By DE Editors

Kistler introduced the Type 9129A, a three-component system designed to offer high-precision measurements of cutting tool machinery forces of up to 8 kN, when turning outside and inside turret lathe diameters, in support of critical manufacturing process monitoring requirements.

The modular Kistler Type 9129A system consists of a dynamometer with corrosion-resistant construction that is further impenetrable to coolants. The dynamometer is comprised of four integral three-component force sensors, the outputs of which are passed to its corresponding 9-way flange socket.  The force sensors are mounted with electrical ground isolation under high preload conditions between the cover plate and two lateral base plates, a specialized mounting technique which allows for minimal temperature errors, as well as force measurements achieved with virtually no displacement. The ground isolation of the force sensors largely prevents EMI and ground loop interference from compromising measurement integrity. When used in conjunction with Kistler Type 1687B and Type 1689B connecting cables,  the dynamometer is environmentally protected to IP67 standards.  

Designed for direct compatibility with industry disk-type turret cutting tool machinery, the Type 9129A is further offered with machinery adapters for VDI tool holding fixtures with 30mm, 40mm and 50mm diameters; Coromant Capto C5 and C6 clamping units; direct tool holding fixtures with 20mm x 40mm or 25mm x 50mm footprint; tool holders for external turning tools measuring 20mm x 20mm or 25mm x 25mm; and tool holders for internal turning tools with 25mm, 32mm or 40mm diameters.

The technical features and specifications of the Kistler Type 9129A allow for simultaneous measurement of the three cutting forces while turning outside and inside diameters on lathes with turret-type tool heads.  In addition, as a stand-alone, the Kistler Type 9129A dynamometer is suitable as a general purpose, multi-component force measurement device, able to be mounted without accessories directly onto a flat base plate.
