How to manufacture this bearing retainer with lowcost

[John Mactavish]

This is a part of the retainer of a roller bearing. We want to improve the manufacturing process of this kind of product. It's a low-end product, we want to produce it with lowcost. In the past we used digital controlled lathe to manufacture this product,and there is a lot of burr,increased the cost. If it is possible to use a punching machine to manufacture it? I'm not a DIEL engineer, so i wanna ask for some help.

This is kind of additional remarks for this topic. You can find the layout from the attachment.

What's the material?

You can also Tumble the parts to debur them.

Looking at your drawing, you could start with steel bar cold-drawn to the outer profile shown. Should be able to obtain close tolerances and decent surface finish from the cold-drawing process. The end post features can be produced by a production process like continuous external rotary or chain broaching.

How many parts do want to make ?

Please post a drawing of the assembly in cross section, with some indicatoin of bearing loads, etc.

It's just a part of the retainer of a roller bearing.This little pillar,we want to manufacture it with high efficiency and lowcost. But now with lathe turning,there is a lot of burr and unable to remove, it makes the efficiency very low. We already use the cold-drawn to form the material. But how to produce this little thing with a better way, that is the key point.

Is the problem the cost of lathe turning the part or the burr removal?

With lathe turning,we need a special fixture to fix this product and manufacture one side each time. After that we need to remove the burr.As you see it's very inefficient. This is a low-end product, high efficiency and low cost that is really improtant.
