Lakshmi Electro Controls & Automation

CNC regrinding of the cutting tools has always been a prerogative of specialised companies or
of users with a large number of tools justifying the huge investment required to carry out these
operations.
MAC 26 4-axis CNC tool grinding machine has been designed for all the companies willing to
sharpen their cutting tools by themselves, in an easy and accurate way, and at a quite low cost.
MAC 26 does not require skilled manpower or special knowledge in the sharpening field.
Through a precision electronic probe, MAC 26 automatically positions the tool to be sharpened
according to the programming software indications: each single tool program can be stored
inside a special library to be then recalled for another sharpening cycle.for regrinding twist drills, end mills, taps,
reamers, countersinks and engraving
tools, both in HSS and Carbide.
