Product Overview
A tool presetter is a precision measuring instrument used to determine the exact geometric dimensions of cutting tools before they are loaded into a CNC machine tool. This device measures critical parameters such as tool length, diameter, and cutting edge radius, allowing operators to input accurate tool offset data into the machine controller without performing trial cuts on the production floor. By separating the tool measurement process from the machining operation, presetters eliminate machine downtime associated with on-machine tool setting and significantly improve first-part accuracy in production environments.
Types and Features
Tool presetters are available in optical, contact, and hybrid configurations, each offering distinct advantages for different precision requirements and budget constraints. Optical presetters use a camera and illumination system to capture a silhouette image of the cutting tool and calculate dimensions through digital image processing, providing non-contact measurement with accuracy typically within two microns. Contact presetters use precision measuring probes that physically touch the cutting edges to determine tool dimensions, offering excellent repeatability for complex tool geometries. Hybrid systems combine both optical and contact measurement in a single unit, providing maximum versatility.
How to Choose
Selecting the right tool presetter involves evaluating measurement range, accuracy requirements, tool holder compatibility, and data integration capabilities with your CNC machine controllers. The measurement capacity must accommodate both the maximum tool length and diameter used in your operations, with adequate clearance for long drill assemblies and large diameter face mills. Consider the level of automation required, as basic manual presetters require operator positioning while fully automatic units can load, measure, and record multiple tools without intervention. Data output format compatibility is essential for seamless integration with your existing workflow.
Replacement and Installation
Installing a new tool presetter requires selecting a location with stable temperature conditions and minimal vibration to ensure measurement accuracy is not compromised by environmental factors. The unit should be mounted on a rigid granite or cast iron surface plate that is leveled to within the manufacturer specification. Connect the presetter to your ne
