Claims

[Scope of Claim for Utility Model Registration] 1. A multi-axis machining machine with multiple machining heads supported on a horizontal saddle, where the distance between the axes of each independent machining head is determined by different thread pitches (leads) on concentric axes. A multi-head spindle inter-spindle adjustment device configured to perform continuous adjustment using the propulsion action of a single threaded rod. 2 A multi-axis processing machine with multiple processing heads supported on a horizontal saddle, in which the distance between the independent axes of each head is adjusted in stages by the expansion and contraction thrust of two-stage telescopic cylinders with different strokes on a concentric axis. A multi-head spindle interspindle adjustment device configured to 3. A multi-axis processing machine with multiple processing heads supported on a horizontal saddle, in which power is transmitted from one spline shaft connected to one drive motor to a gear box in each processing head to a spindle via a bevel gear. On the other hand, the axis of a multi-head spindle is used to adjust the distance between the axes of each independent machining head continuously or stepwise using a threaded rod with a different thread pitch or a two-stage telescopic cylinder on a concentric axis parallel to the spline shaft. Interval adjustment device.
