15. OPERATION Model SB1029 Setup for a Typical Grinding Operation Once you have chosen the proper wheel for the operation and properly installed the magnetic chuck on the table use the following procedures to prepare for a grinding operation To prepare for a grinding operation 1 DISCONNECT MACHINE FROM POWER 2 ensure flat mating surfaces on the workpiece and the magnetic chuck surface grind and stone the top of the chuck and the bottom of the workpiece Clean all surfaces to make sure they are free of contaminants 3 Make sure the magnetic chuck is turned OFF then place the workpiece onto the chuck Once the workpiece 1s positioned as needed turn the magnetic chuck ON 4 Make sure the grinding wheel is not contacting the workpiece connect the grinder to power then turn the motor ON Grinder Operation Grinding with a surface grinder 1s a delicate process that takes practice skill and knowledge In addition to this the method used for any one procedure will depend on a number of factors including but not limited to the material being ground the grinding wheel being used the quality and calibration of measuring tools and the finish that 1s desired For these reasons specific techniques are not outlined in this manual We recommend that you consult books trade magazines metalworking experts and other reliable resources for techniques pertaining to the specific tasks you wish to perform T
