Abstract
The part (1) to be machined, which exhibits an axis of revolution (aa') is secured in a rotatable spindle (11) forming part of a headstock (10) movable in translation on the framework of the grinding machine according to a longitudinal axis (X) parallel to the axis of revolution (aa'). A support (16) fixed to the framework and in the immediate proximity of which is arranged a grindstone (18), serves as lateral support to a portion of the part (1) to be machined. Grinding of the part (1) by the grindstone (18) over an arbitrary length capable of exceeding 1000 times its diameter, is effected by displacing the headstock (10) by such length in the sense of the longitudinal axis (X).
Claims4
A grinding machine comprising:
- a framework;
- a head stock positioned on said framework, said head stock including a spindle means for holding a part to be machined, said spindle means also for rotating the part about a part rotation axis;
- a support means positioned on said framework spaced from said headstock in a direction of said part rotation axis, said support means for supporting the part, said support means includes a sustaining foot connected to said framework, said sustaining foot defining a notch for receiving the part, said support means also including a pressure roller means positioned on substantially an opposite side of the part from said sustaining foot and for applying force to the part, said pressure roller means is rotatable about a pressure axis substantially parallel to said part rotation axis;
- grinding means positioned on a grinding side of said support means substantially opposite said headstock along said part rotation axis, said grinding means for grinding a portion of the part extending from said support means in a direction of said part rotation axis, said grinding means includes a grinding stone rotatable about a grinding axis substantially parallel to said part rotation axis, a first line connecting said part rotation axis and said pressure axis is angularly spaced by approximately 135 degrees from a second line connecting said part rotation axis and said grinding axis;
- headstock feed means for moving said headstock along said framework and along said part rotation axis to extend additional portions of the part from said support means.
