The actual precision depends on the condition of the grinding wheel (periodic dressing), the workpiece material, the coolant, and the operator's experience.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eWhat does the suffix \"PLC\" mean in the Bernardo BSG 2 Surface Grinder model?\u003c\/summary\u003e\n\u003cp\u003eThe PLC suffix indicates that the grinder is equipped with a programmable PLC control — it allows setting automatic grinding cycles (number of passes, depth per pass, feed) without manual intervention during the cycle. Compared to the manual version, it reduces cycle times and produces more repeatable results on batches of identical parts.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eWhich abrasive wheel to use for steel vs cast iron vs aluminum?\u003c\/summary\u003e\n\u003cp\u003eSteel: Corundum wheel (Al₂O₃) A46K–A60K.
