摘要

Machine tool, comprising:a tool head (30, 212), of a drilling schneider (100, 242) and a grinding tool (102, 104, 236, 238, 426, 428) comprises;Rotating means (44, 221) for rotating the tool head (30, 212);a main shaft (32, 224), the said means (44, 221) with the tool head (30, 212) and of the rotary means (44, 221) to the tool head (30, 212) transmits rotational force;a holder (34, 36, 228), wherein the main shaft (32, 224) by means of the holder (34, 36, 228) extending axially and in the holder (34, 36, 228) is rotatably mounted; andMoving means (58, 226) for moving the holder (34, 36, 228) in an axial direction of the main shaft (32, 224),the diameter of the main shaft (32, 224) remains unchanged, while it by means of the rotating means (44, 221) is rotated, and indeed both during a drilling operation, in which the tool head (30, 212) during the drilling of a workpiece by means of the drilling or cutting..
