Precision grinding machine is in its own high precision, in the use of grinding out the product quality precision, high precision reflected in the basic embryo casting material is good, in the manufacture of grinding machine used in some parts of the coordination is also very important, generally the main shaft, that is, the main shaft of the grinding machine is now basically the original spindle, vibration and noise are very small, The screw on the bed is also a precision screw thread or ball screw, which must be imported into China after precision grinding, in the assembly problem, the same machine tool parts assembly, different masters assemble the effect is not the same, this requires experience, but a long time of honing and understanding, in the assembly to reflect the accuracy of the final molding, When the precision grinder is produced, the master must test to know the precision of the grinder, the precision grinder is controlled in a little bit of precision, especially the small grinder, it is within 2μ. so that customers can buy the past production parts to grind out the workpiece below 2μ. The precision is related to the machine error, the smaller the machine error, the higher the precision.
