This is a plate that securely fixes the MS front and rear units. M6 cap bolt holes have been added for mounting on a milling machine. By attaching the separately sold Pera Nislunder shims, finishing processing such as step-down machining can be done using a bar file. ※10/2 Update: The height of the jig itself was lowered by 1mm to accommodate shims, as the jig could be damaged when processing with a 3mm cut.
