摘要

The present invention in one or more embodiments provides a roller tool for roughening a friction ring of a brake disk, the roller tool including a roller body including inner and outer ends and a casing surface positioned there-between, the inner end differing in cross-section dimension than the outer end, the casing surface including thereupon one or more protrusions for contacting the friction ring. The roller tool may further include a support frame supporting the roller body. The support frame may include a short leg connected to the outer end of the roller body and a long leg connected to the inner end of the roller body.
