Tips for Lower Grinding
Costs
- Parallelism is easier to achieve than flatness. You may be
able to reduce your costs by specifying a greater tolerance for
flatness than for parallelism.
- Larger pieces are more difficult to
hold flat.
Thermal stress relieving before grinding can aid in this, reduce
required stock removal,
and lower your costs.
- Thicker pieces or higher strength steels require
more stock removal. Press flattening and stress relieving can help
to avoid at
least part of this.
- Pieces with thickness tolerances better than
+/- 0.003 may require additional processing, usually in the form
of reciprocal grinding.
Avoid specifying tight tolerances unless they are absolutely necessary.
- Milling offers faster stock removal and tolerances close to those
achieved by grinding, which translates into reduced costs,
particularly on very large pieces.
