Abstract
Abstract A machine tool for processing workpieces of various shapes comprises three processing units each mounted on a carriage to move in three axes of coordinates and each being rotatable about a horizontal axis. Each processing unit carries a tool holder having tools and being turnable in two opposite directions. A workpiece is clamped in a workpiece holder so that it is immovable during operation and can be treated at least at three sides thereof simultaneously.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
188 words
A machine tool, comprising: (a) a workpiece holder supporting a workpiece so that it is immovable during operation; (b) at least three modular identical processing units carrying tool holders each rotatable about a horizontal axis of rotation, each of the tool holders supporting at a periphery thereof a number of tools; (c) said processing units being positioned relative to said workpiece holder so that the workpiece is treated simultaneously at least three sides thereof with said tools; (d) means for driving said processing units along at least three axes of movement mutually perpendicular to each other; (e) means for pivotably mounting at least one of said processing units about a vertical axis normal to one of said axes of movement and for locking said units in a respective pivoted position; and (f) said workpiece holder being common to all said processing units and means for turnably mounting said holder about a horizontal axis from a loading position to an operation position and additionally about another horizontal axis and for locking said holder in any desired angular position, means for pivotably mounting said workpiece holder about said vertical axis.
Claim 2
Dependent Claim
188 words
A machine tool, comprising: (a) a workpiece holder supporting a workpiece so that it is immovable during operation; (b) at least three modular identical processing units carrying tool holders each rotatable about a horizontal axis of rotation, each of the tool holders supporting at a periphery thereof a number of tools; (c) said processing units being positioned relative to said workpiece holder so that the workpiece is treated simultaneously at least three sides thereof with said tools; (d) means for driving said processing units along at least three axes of movement mutually perpendicular to each other; (e) means for pivotably mounting at least one of said processing units about a vertical axis normal to one of said axes of movement and for locking said units in a respective pivoted position; and (f) said workpiece holder being common to all said processing units and means for turnably mounting said holder about a horizontal axis from a loading position to an operation position and additionally about another horizontal axis and for locking said holder in any desired angular position, means for pivotably mounting said workpiece holder about said vertical axis.
