Spindle is the core part of machine tools, the accuracy of the spindle’s outer thread affects the accuracy of assembly.
YINSH especially introduced outer thread grinding machines from Europe and America, like Reishauer, JONES & LAMSON and MATRIX.
Through gripping the workpiece with two lathe centers, we assure the concentricity and verticality of the outer thread and spindle meets requirement for spindle assembling.
For different types of plastic injection mold, we are capable of processing those special thread which can’t make out by CNC lathe and CNC milling machine.
By using all kinds of abrasive materials, we can process vairous die steels to meet the requirement for plastic injection mold from customers.
