Rollomatic vs Rollomatic · CNC Grinding Machines
Summary
The Rollomatic GrindSmart 629XW and the Rollomatic GrindSmart 830XW are both CNC tool grinders for end mills, drills and other rotary cutting tools. Rollomatic publishes few comparable figures for this pair, so the table covers only spindle power, control and weight.
The Rollomatic GrindSmart 629XW lists the higher spindle power, 13 kW (17.4 hp) against 11 kW (15 HP), direct drive, and is the lighter machine at 5,200 kg (11,464 lb) against 6200 kg. It runs Rollomatic's proprietary CNC, where the Rollomatic GrindSmart 830XW runs a FANUC 30iMB. The Rollomatic GrindSmart 830XW is aimed at a wider range of tool diameters, more wheel packs on call and longer unattended runs from a larger cassette loader.
