Abstract
A method and apparatus for profiling a grinding wheel (12) used to grind a workpiece (6) includes selectively feeding the grinding wheel radially against a dressing roller (19) to dress the wheel. Between successive dressing operations, the dressing roller (19) is conditioned with a conditioning wheel (50) movable radially thereto. Either the dressing roller or the conditioning wheel is movable axially relative to the other. The dressing roller (19) makes linear contact with the grinding wheel (12), and makes pointwise contact with the conditioning wheel (50). The relative radial and axial movements between the conditioning wheel (50) and the dressing roller (19) are synchronized by program control.
Claims20
A method for dressing a grinding wheel (12) by a profiled dressing roller (19), said method comprising:
- moving said grinding wheel (12) radially against said dressing roller (19), said dressing roller (19) linearly contacting said grinding wheel (12) to dress said wheel;
- and
- conditioning said dressing roller (19) with a conditioning mechanism (25, 50) moved radially thereto, wherein said conditioning step includes contacting said dressing roller (19) substantially in point contact with said conditioning mechanism (25, 50) and one of said dressing roller and said conditioning mechanism being axially movable synchronously by program control with radial movement of said conditioning mechanism (25, 50) relative to said dressing roller (19).
An apparatus for dressing a grinding wheel, comprising:
- a first spindle (10) driven rotatably around a first axis (11) by a first drive mechanism (9), a grinding wheel (12) being mounted on said first spindle (10);
- a second spindle (17) driven rotatably around a second axis (18) by a second drive mechanism (16);
- a dressing roller (19) mounted on said second spindle (17);
- a first feed mechanism (13) for displacing said first spindle (10) radially relative to said second spindle (17) along a third axis (8);
- a conditioning mechanism (25, 50) displaced radially relative to said second spindle (17);
- a second feed mechanism (23) for displacing said conditioning mechanism (25, 50) radially relative to said second spindle (17);
- a third feed mechanism (20) for displacing said dressing roller (19) axially relative to said conditioning mechanism (25, 50);
- and
- a controller (33) which synchronizes movement of said second and third feed mechanisms (23, 20).
