Program editor software extends CAD support
Active Editor Pro dramatically increases the number of users who can benefit from its simple programming style, by adding support for CAD models from a large variety of CAD formats.
Setting is carried out at normal spindle cutting speeds, allowing errors caused by radial run-out of the tool and tool holder to be identified and compensated.
Further advantages of the NC1 system include the ability to measure tools anywhere along the laser beam, minimising cycle times, and the measurement of tools of only 0.2mm diameter.
NC1 is especially suited to the increasing requirement for broken tool detection in unmanned machining operations, where tool damage can cause costly scrap or re-work.

After each machining operation, tools can be passed through the NC1's laser beam at rapid feed rates to check for damage.
Software developed by Renishaw for a wide range of CNC controls allows the NC1 system to set most common types of tooling.
Typical cycles include static length setting of drills, rotating length setting of tools such as face mills, and rotating diameter setting of slot drills and boring bars.
The powerful software also allows each facet of a multi-faceted tool to be checked, whilst thermal compensation for changes in machine temperature is included within the software routines.
The NC1 system comprises innovative laser technology to ensure accurate operation, easy installation and minimal maintenance.
A compact and robust laser-based transmitter sends a visible beam to a receiver unit.
System electronics detect when a tool breaks the laser beam and output signals are sent to the machine's controller, allowing the position of tips, teeth or cutting edges to be rapidly established.
Accurate alignment of the laser beam is achieved using a unique, integral 'Virtual Pivot' system developed by Renishaw.
A further innovative development is a protection system that uses a continuous stream of air through the laser beam apertures, not mechanical shutters, minimising maintenance.
Available in fixed or separate systems, operating with up to 2 metres separation between transmitter and receiver, the NC1 non-contact tool setter can be purchased with new machines, or retrofitted to machining centres already installed. Request a free brochure from Renishaw ...
