FIELD: process engineering.SUBSTANCE: invention relates to perfection of cutting machine blade design. Cutting machine comprises cylindrical cutting disc and wearing segment. One end surface of cutting disc has one or several cutting blades extending, in fact, radially relative to said disc. Wearing segment serves to support said blade. Cutting machine has wearing surface arranged behind the bale for production of stresses caused by timber cutting. Blade at least its one element is arranged to rest on the blade and on wearing surface. Wearing segment surface makes a part of a portion of desirable size of wearing surface. Coating is applied on said segment surface for protection against said stresses. Said wearing segment is composed by two or more consecutive parts. Said coating is applied by high-rate plasma-gas spraying of at least one carbide layer. Blade segment is secured to cutting disc by two bolts extending there through, welding or by combination thereof.EFFECT: higher wear resistance.8 cl, 4 dwg |
