摘要： A feed roller is provided with feed roller head having a helical carbide gripping inserts. The gripping inserts extend along a helical path and are configured to grip and shift a work piece in a predetermined direction. The gripping inserts are secured to the feed roller body in a helical slot formed between a wall of the feed roller body and a plurality of clamping wedges. The clamping wedge facilitates locking and securing the gripping insert to the feed roller body in a radial direction in response to centrifugal forces created as the feed roller head rotates.

摘要： A rotary cutter head is provided with helical carbide cutting blade inserts. The blade inserts extend along a helical path and are configured for cutting rotation in a predetermined direction. The blade inserts are secured to the cutter head body in a helical slot formed between a wall of the cutter head body and a plurality of clamping wedges. The blade insert may have a tapered body that facilitates locking and securing the blade insert to the cutter head body in a radial direction in response to centrifugal forces created as the rotary cutter head rotates.

摘要翻译： 旋转刀头设置有螺旋形硬质合金刀片刀片。 刀片刀片沿着螺旋路径延伸并且被配置为沿预定方向切割旋转。 刀片插入件以形成在刀头本体的壁和多个夹紧楔之间的螺旋槽固定到刀头本体。 刀片插入件可以具有锥形体，其有助于响应于当旋转刀头旋转时产生的离心力，沿着径向方向将刀片插入件锁定并固定到刀头本体。
