Abstract
The present invention provides a material for built up edge formation having a resin block containing a high molecular weight compound having a weight average molecular weight of 5×104 or higher and 1×106 or lower, a medium molecular weight compound having a weight average molecular weight of 1×103 or higher and lower than 5×104, and a carbon.
Claims11
A material for built up edge formation, having a resin block containing:
- a high molecular weight compound (A) having a weight average molecular weight of 5×104 or higher and 1×106 or lower;
- a medium molecular weight compound (B) having a weight average molecular weight of 1×103 or higher and lower than 5×104;
- and
- a carbon (C),
- wherein the material for built up edge formation further comprises a difficult-to-cut block having a Vickers hardness of 300° or more below the resin block such that the material for built up edge formation forms a built up edge on a cutting tool prior to cutting a work.
