In many types of application, there is only a requirement for a moderate level of control of the final product. When components and parts require internal grinding, there is often a need for extremely tight tolerances.
In most cases, this is grinding process that is completed on bar or rods and may include a straight interior grinding process or a more complex shape. As with all grinding, both interior and exterior, it is typically completed using CNC or computer numerical control equipment. This allows for the production of extremely tight tolerances on parts, which is critical in all industries.
The Exacting Requirements
With the use of CNC internal grinding equipment, it is possible to have the exact replica of the original CAD/CAM drawing. This means every part will be identical to each other, as well as to the original.
For Original Equipment Manufacturers, this is critical. It allows for the exact replication of the component for both internal and external grinding requirements not just within production runs, but also between production runs.
Choosing not only the equipment but also the grinding tool is still the responsibility of the operator. Choosing an experienced shop with the expertise to complete the internal grinding to your specifications will always be an important factor.
All equipment will have upper limitations as to the size of the workpiece which can be accommodated. Specialized grinding services tend to offer a wider range of workpiece options.
Suitable Materials
In the past, most machining and grinding services only worked with metals and alloys. Today, the top companies will also offer grinding, both internal and external, for a much wider range of materials. This can include resins and plastics as well as superalloys and exotic alloys.
It is important to consider the quality of the equipment and the experience of the team when working with non-standard materials. Choosing a grinding service with expertise and experience with the metal or alloy will always be essential.
