CNC tangential grinder EQUIPTOP ESG precision series

The ESG-CNC series from EQUIPTOP comprises high-precision CNC tangential grinders with servo drive in the three axes for the flat grinding of small and medium-sized parts. The range is divided into two sub-families according to the type of guide: the models ESG-1224CNC and ESG-1228CNC, with high-precision ball linear guides, and the models ESG-64CNC, ESG-84CNC and ESG-104CNC, with SP class roller bearing linear guides for greater stiffness under heavy-duty operating conditions.

The work surfaces range from 300 × 600 mm until 400 × 1.100 mmwith maximum grinding lengths of 600 to 1,100 mm and widths of 300 to 400 mmLongitudinal travel of the table is infinitely variable between 0 and 25 m/min in all models. The spindle operates at variable speed of 0 to 1,800 rpmactioned by motor of 10 CV.

Unlike large-format series with longitudinal hydraulic drive, this series uses direct drive transmission by servo motor on axes X, Y and Z, eliminating clearances and ensuring repeatable positioning. The minimum input resolution is 0,001 mm in all axes, with MPG steering wheel in three scales: ×1, ×10 and ×100 Automatic vertical penetration feed oscillates between 0.001 y 0.05 mm per pass. The automatic cross travel reaches the 350 mm in the ESG-12xx models and the 450 mm in the ESG-64/84/104 models.

The CNC control is available with systems Fanuc, Mitsubishi, Siemens or Delta to choose. The casting structure incorporates FEM analysis with reinforcement ribs and internal stress-relief annealing to optimize stiffness under load. The teeth are of Ø355 × 50 × 127 mm for the ESG-12xx models and de Ø405 × 50 × 127 mm for the ESG-64/84/104 models.

This series targets manufacturers who incorporate or expand capacity of high-precision CNC plane grinding in small and medium format parts, in sectors such as cutting tools, precision components, industrial electronics and mold and die tooling.
