Centerless cylindrical grinding machine bar stock AND METHOD OF centerless cylindrical grinding

摘要

Bestsentrovoj 1. Grinding machine for grinding bar stock for the passage of the cylindrical external contour, comprising the following features: a) a composite set of driven in rotation of the drive and the grinding wheel (3, 5) which are arranged opposite one another on both sides of the workpiece (1) with passing parallel to its longitudinal axis (2) rotation axles (4, 6), b) a grinding mode, and drive wheels (3, 5) serves for plunging the workpiece (1), which in its longitudinal direction (2) passes through a set of circles c) maintaining blank (1) supporting the blade (7) located inside formed leading and grinding wheels (3, 5) the expanding grinding zone (15), wherein the longitudinal axis (2) of the blank (1) with respect to the reference plane (14) passing through the axis rotation (4, 6) leading and grinding wheels (3, 5), always faces away from the base plane (14) within the area of ​​the grinding zone (15) between the base plane (14) and the supporting surface (8) of the supporting blade (7) d) each of the leading and grinding wheels (3, 5) located at a lateral distance from their adjacent circle by ichayuschiysya that includes the following additional features: d) and drive wheels (3, 5) are arranged offset relative to each other in the axial direction, and e) leading circles (3) are in axial gaps (24) between the grinding wheels ( 5) and naoborot.2. Machine according to claim 1, characterized in that the principal composite sample set comprises one row of two or more circles (3, 5), of which one row of leading wheels (3) arranged on one side of the blank (1) and the other row grinding wheels (5) - in front of the other storony.3 it.
