Abstract
A grinding machine for grinding surfaces of workpieces supported on a frame comprises a first slide mounted on the frame for reciprocating movements along a fixed length path toward and away from the workpieces, the first slide supporting a second slide which carries grinding wheels. The second slide is adjustably mounted on the first slide for movements with the latter so as to effect movement of the grinding wheels into and out of engagement with the workpieces and for movements relative to the frst slide so as to compensate for erosion of the grinding wheels caused by grinding or dressing operations. The machine includes dressing tools for the grinding wheels and which are operable in timed relation to the reciprocating movements of the slides to effect dressing of the grinding wheels.
Claims19
A grinding machine construction comprising a frame;
- workpiece supporting means carried by said frame;
- a first slide;
- means guiding said first slide for reciprocating movements along a path between first and second positions remote from and adjacent said workpiece supporting means, respectively;
- drive means coupled to said first slide for reciprocating the latter;
- a second slide;
- grinding means carried by said second slide and having a surface engageable with a workpiece supported by said workpiece supporting means;
- adjustable means coupling said first and second slides for reciprocating the latter conjointly with said first slide between a first position remote from said workpiece supporting means to a second position adjacent said workpiece supporting means and in which second position said surface of said grinding means is at a predetermined distance from said workpiece supporting means;
- and means for adjusting said adjustable means to effect movement of said second slide relative to said first slide in a direction toward said workpiece supporting means an amount to compensate for wear of said grinding means and thereby maintain said predetermined distance constant regardless of wear of said grinding means.
A machine tool construction comprising frame means;
- workpiece supporting means carried by said frame means;
- slide means carried by said frame means for movement toward said workpiece supporting means from a first position spaced from said workpiece supporting means to a second position less spaced from said workpiece supporting means, and return;
- tool support means;
- means mounting said tool support means on said slide means for movements with the latter and for movements relative to said slide means toward and away from said workpiece supporting means;
- movable means carried by said frame means in the path of movement of said slide means in a direction toward said workpiece supporting means for interrupting such movement of said slide means when it reaches said second position;
- drive means for moving said slide means between said positions;
- and means coupling said drive means and said movable interrupting means for moving the latter in a direction to enable further movement of said slide means toward said workpiece supporting means from said second position.
A grinding machine construction comprising frame means;
- workpiece supporting means carried by said frame means;
- slide means;
- support means for a tool composed of erodable material;
- means mounting said support means on said slide means for movements with the latter in a direction toward said workpiece supporting means and for movements relative to said slide means in said direction;
- means mounting said slide means on said frame means for movement in said direction from a first position in which a surface of said tool is spaced from said workpiece supporting means to a second position in which said surface is less spaced from said workpiece supporting means and is located a predetermined distance from a workpiece supported by said workpiece supporting means;
- drive means;
- drive transmitting means coupling said drive means and said slide means for moving the latter between said positions;
- operating means for moving said tool support means relative to said slide means toward said workpiece support means;
- and means for operating said operating means to vary the location of said tool support means by an amount such that said predetermined distance is substantially constant regardless of erosion of the surface of such grinding wheel.
A machine tool construction comprising a frame;
- means carried by said frame for supporting a workpiece;
- a first slide mounted on said frame for reciprocating movements in directions toward and away from said workpiece supporting means;
- a second slide for supporting a tool adapted to engage a workpiece supported by said workpiece supporting means;
- means mounting said second slide for movements with said first slide and for adjustment in said directions relative to said first slide;
- means for adjusting said second slide relative to said first slide;
- drive means;
- drive transmitting means coupling said drive means to said first slide for reciprocating the latter;
- and means coupling said adjusting means and said drive means for operating said adjusting means in timed relation to the movements of said first slide.
