Abstract
A grinding tool for grinding an end surface of a tubular body has a grinding wheel having a grinding surface and a rotary drive opposite the grinding surface that rotates the grinding wheel about a rotary axis. The grinding surface defines an inverted frustoconical shape that is centered on the rotary axis. The grinding surface is sized to contact the end surface of the end of the tubular body. An alignment guide having an alignment surface is sized to engage the tubular body and align the grinding surface with an outer edge of the tubular body when the grinding wheel engages the end of the tubular body.
Claims17
A grinding tool for grinding an end surface of a tubular body, the grinding tool comprising:
- a rotary drive having a rotary axis;
- a grinding wheel carried by the rotary drive, the grinding wheel having a grinding surface that is defined by an inverted frustoconical shape centered on the rotary axis and that is sized to contact the end surface of the tubular body;
- and
- an alignment guide that is sized to engage the tubular body and align the grinding surface with an outer edge of the tubular body when the grinding wheel engages the end of the tubular body.
A method of grinding an end surface of an end of a tubular body, the method comprising:
- providing a grinding tool comprising:
- a grinding wheel having a grinding surface and a rotary axis, wherein the grinding surface is defined by an inverted frustoconical shape that is centered on the rotary axis, the grinding surface being sized to engage the end surface of the tubular body;
- and
- an alignment guide adjacent to the grinding wheel, the alignment guide being rotatable relative to the grinding wheel;
- bringing the alignment surface into engagement with tubular body;
- using the engagement between the alignment guide and the end surface, aligning the grinding surface with the end surface of the tubular body;
- and
- rotating the grinding wheel to apply a grinding force to the end surface of the tubular body.
