Tool Changers
DATRON has both rotary and rack-style tool changers depending on machine model. Based on spindle selection direct-shank and HSK tool holding systems are available (see PDF below).
Included with the tool change unit is a tool length sensor. This is used to measure the length or offset of each tool in the magazine and the data is stored in the control software. This sensor consists of a high precision micro switch with a carbide post mounted above. The sealed assembly is mounted at one end of the tool change unit beneath the cover. The switch is sensitive enough to measure the smallest end mill or drill without breakage. The tool offset management software allows the operator to measure as it needs to or automatically in a program. A program can even be set up such that during the production run, if it measures the tool and has determined it is broken, it will automatically change the tool with a surrogate tool and re-machine from the beginning of that tool path.
DATRON’s Automatic Tool Management System™ is made up of three separate components working in synergistically — the tool checker, the tool changer, and the software. The tool checker is a mechanical sensor that measures tool length and detects the broken tool. The tool changer is a rack or tray that has space for spare tools and sockets where the machine places broken tools before picking up a replacement. Operators can stock the rack with spare tools, thereby having a ready supply should tools break during “lights out” operation. The software is a macro program that can be set up to run a tool check after executing a number of lines of code. For example, a tool check macro can initiate a check after every 500 lines of code by employing an “if/then” statement such as, “Measure this tool; if the length is shorter than the parameter (listed in the software’s tool database), then change the tool.”
Add Accuracy with:
HSK E-25 The HSK-E inserts developed by DATRON and Schunk are solidly built and come with a concentricity of <3 μm and guarantee highest precision during the machining process.
Renishaw Compact Laser This system has an integrated transmitter and receiver.
Fast, precise and automatic, contact-free tool measurement and breakage detection on turning tool. The times for tool measurement can be reduced by up to 90%. The automatic tool breakage control ensures reliable manufacturing in fully automatic operation. The minimum tool length depends on the spindle, spray system, other attachments and the installation location.
Blum Z-Nano Tool Sensor Allows tool lengths to be measured quickly, precisely and automatically. The functional principle with linear guidance is absolutely free of transverse forces, so that even sensitive and very small tools can be measured.
