Tool head, the machine tool and the drilling process for drilling a cylinder block with the use of the machine tool

摘要

Machine tool, comprising:a tool head (30), of a drilling schneider (100) and a grinding tool (102, 104) comprises;Rotating means (44) for rotating the tool head (30);a hollow main shaft (32), the said means (44) with the tool head (30) and of the rotary means (44) to the tool head (30) transmits rotational force;a holder (34, 36), wherein the main shaft (32) by means of the holder (34, 36) extending axially and in the holder (34, 36) is rotatably held; andMoving means (58) for moving the holder (34, 36) in a with respect to the main shaft (32) axial direction;a rod (33), which in the main shaft (32) is recorded and is axially movable,the diameter of the main shaft (32) remains unchanged, while it by means of the rotating means (44) is rotated, and indeed both during a drilling operation, in which the tool head (30) during the drilling, cutting a workpiece by means of the drilling cylinder (100) and rotated in the direction of the workpiece is moved, as well as during a grinding operation, in which the tool head (30) during the grinding operation of the workpiece by means of the grinding tool (102, 104) and rotated back - and forth,the machine tool the drilling operation and the grinding operation by means of the radial expansion of the drilling or cutting (100) and of the grinding tool (102, 104) is carried out, ..
