E68LA Presetter

One of our most advanced tool presetting machines, The E68LA presetter machine is the autofocus option of the E68L. The autofocus function allows for search and automatic measurement for single and multi-edged cutters, providing an even higher level of precision.

Compared to the lower specification models, all quite capable in their own right, the construction, performance and design (particularly the electronic and software capability) provides considerable advantages.

Designed completely free-standing on its own integral base; E68LA features ground granite and stainless steel construction combined with a large Twin Screen digital camera system with full industrial PC architecture – these electronics and software provide operational and functional simplicity that is second to none.

Featuring the ultimate high precision spindle system that is fully interchangeable and utilises a one-piece cartridge with full mechanical tool clamping (pneumatic system) capable of clamping ISO/BT, HSK and Polygonal taper tool shanks - eliminating the need for adaptors and the errors associated with their use. The construction of this system is more akin to a machine tool spindle than a tool presetter spindle!

The E68LA is also 'future proof' in that within the next twelve months our new 'MUST', Measurement User Support Technology, will become available to all existing users as an 'add on' option. The solution provides a whole new spin for 'CNC' on a tool presetter and features a unique and user friendly measuring program encased within a smart interface to allow selection and setting of all measuring points, number of cutters, theoretical values and tolerances. All on one single page and you decide how to measure and where/how to export the data (Post processor, TiD, RFID or simply save and print a complete report).

Axis Movemements

All axis movements on the E68LA are servo controlled with absolutely no operator contact with the column. This drastically increases machine accuracy and repeatability over similar machines which incorporate the movement via a manual handle mounted on the column.

Software Package 

Integrated within the innovative software package is a complete tool management system and network port. Working via your DNC system our software converts measured tool data into CNC code for direct loading into the machine controller and associated tool offset pages.

Functionality 

Further capabilities include the ability to import and export .DXF CAD profiles for detailed checking and comparison on the twin screen camera system.
