摘要： An engine includes a cylinder block including a cylinder hole, a crank shaft as an offset crank, and a connecting rod that connects the piston and the crank shaft. An inclined surface is provided on an entire circumference of a crank-shaft-side opening edge of one end of the cylinder hole. When viewed in the axial direction of the crank shaft, a boundary line between the inclined surface and the cylinder hole extends towards the other end of the cylinder hole as it extends toward an offset side on which the crank shaft is offset from the center axis of the cylinder hole. The offset crank engine has the entire circumference of the crank-shaft-side opening edge of the cylinder hole chamfered without any bad influence on the sliding surface and posture of the piston to avoid interference between the crank-shaft-side opening edge of the cylinder hole and the connecting rod.

摘要： A method for milling a planar surface, during which a milling cutter, an axis of rotation of which is perpendicular to a surface to be machined, is moved in a direction parallel to the plane of the surface, to machine the surface in a single machining operation, over a predetermined layer of material, using a single milling head, and the milling cutter, in a same axial position relative to the surface to be machined, simultaneously carries out rough working, at least one intermediate finishing operation, and a finishing operation over a same layer of material.

摘要： A method for the machine-milling of intake and/or exhaust ducts formed in a cylinder head includes working off the inner wall surfaces of the intake and/or exhaust ducts at least in part, preferably completely, with a multi-axis, preferably five-axis, CNC-controlled cherry head in a stabbing movement. Grooves are thus formed in the inner wall surfaces that extend primarily in the flow direction of the ducts.

摘要： A method is provided for producing a ventilation bore in a thrust bearing of a crankcase of a reciprocating internal combustion engine by milling. The milling cutter is an angled-head milling cutter, which is introduced into the crankcase in the direction of a cylinder longitudinal axis and is moved in the direction of a crankcase longitudinal axis until the thrust bearing is perforated. Subsequently, the angled-head milling cutter is moved back in the direction of the crankcase longitudinal axis and removed from the crankcase by moving the angled-head milling cutter in the direction of the cylinder longitudinal axis. Internal stresses in the crankcase are avoided by the production of the ventilation bore, as a result of which the strength of the crankcase is increased.

摘要： A face milling tool includes a tool body having an axial front end surface with several seats. Each seat has support surfaces for rotationally locking and supporting a tangential cutting insert in the seat. One of the support surfaces is a flat axial support surface for supporting the tangential cutting insert in an axial direction defined by the central rotation axis. The flat axial support surface extends perpendicular to the central rotation axis and is situated axially foremost in the seat. A side wall of each seat is formed out of round side support surfaces. Each tangential cutting insert includes an axial back side with a flat axial contact surface abutting the flat axial support surface and a projecting member extending axially from the flat axial contact surface and having a circumferential side surface forming out of round side contact surfaces abutting the out of round side support surfaces.
