Actual precision depends on the condition of the grinding wheel (periodic dressing), workpiece material, coolant, and operator experience.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eWhat does the \"PLC\" suffix mean in the Bernardo BSG 2 surface grinding machine model?\u003c\/summary\u003e\n\u003cp\u003eThe PLC suffix indicates that the grinding machine 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 should be used for steel vs. cast iron vs. aluminum?\u003c\/summary\u003e\n\u003cp\u003eSteel: aluminum oxide (Al₂O₃) A46K–A60K wheel. Cast iron: silicon carbide (SiC) C46K–C60K wheel. Aluminum: silicon carbide C46J–C60J wheel with abundant lubrication.
