A stripper guide is said to have the following roles.

	1.	Restricting the behavior of the stripper in order for the stripper to guide the punch.
	2.	Heightening the dynamic accuracy of the punch and die.
	3.	Making the assembly of the punch and die easy.
	4.	Making the maintenance easy, etc.

However, these can change depending on the method of assembling the stripper guide.

Some examples of these are shown in Fig. 1 and Fig. 2.

Figure 1 shows the method of assembling the stripper guide after mating the punch and die.

This can be said to be the form used initially when stripper guides were started to be used. In the times when it was not possible to carry out high precision plate machining, after mating the die and the punch cutting edges, the bush is fixed using Devcon (adhesive). This is effective for behavior of the stripper, dynamic accuracy, and ease of maintenance.

The form shown in Fig. 2 may be said to be the form of punch and die assembly in recent times.

The plate is machined to a high accuracy, initially the stripper guide post and the bush are made to stand on the plate, and the punch and die are mated taking the stripper guide as the reference. At this time, it is possible to mate the punch and die even if the plate has not been assembled inside the die set. Assembling in the die set is also carried out after mating the punch and die. All the roles of the guide indicated above are included in this method. However, there will be differences in the accuracy depending on the method of assembling the guide bush and the post. Techniques will become necessary matching with the required accuracy. For example, this is the difference due to selecting the method of fixing the bush either the press fitting method or the adhesive fixing method, etc. The reason that there are a large number of types of stripper guides among the standard parts is probably the result of pursuing parts to suit the quality expected from the punches and dies.

It is dangerous to judge the function of the stripper guide from its finished form, and it is necessary to consider from the method of assembling the stripper guide post and bush.
