Bison clamps are industrial workholding devices used in securing and holding the workpiece in position during manufacturing processes. Depending on the specific model, some of the applications that Bison workholding devices may be used include:
- Milling
- Turning
- Drilling
- Grinding
- CNC machining
- Production machining
- Precision manufacturing
The selection of the correct tool will depend upon the nature of the workpiece, machine, desired accuracy, forces for cutting/grinding, etc. The purpose of holding the component during grinding is basically that of maintaining an accurate position of the workpiece.
Can Bison Clamping Tools Be Used for Grinding?
Absolutely, some Bison clamping systems are indeed capable of performing grinding tasks. The key issue here is that it all depends on the particular product and grinding system.
Grinding is the process where removal of material happens through an abrasive wheel rather than through a conventional cutting tool. Despite the fact that grinding forces differ from milling and turning forces, this process may be very sensitive to vibrations and motion of the part being processed.
Requirements of a good Bison clamping device should be:
- Provision for securing the workpiece
- Good rigidity
- Reproducibility of position
- Appropriate clamping force
- Compatibility with the grinding machine
- Enough clearance around the grinding wheel
- Proper degree of accuracy
Before using any specific Bison clamping device for grinding operations, make sure to review its technical specifications and applications.
Which Bison Clamping Tools May Be Suitable for Grinding?
The selection of the right Bison product is based on the grinding operation and the workpiece involved.
Machine Vises
A precision machine vise can be considered in securing the appropriate workpiece while undergoing grinding operations, especially if the workpiece has flat and parallel sides. In selecting a vise, some considerations must be made, such as:
- Accuracy of the jaws
- Clamping capacity
- Repeatability
- Geometry of the workpiece
- Compatibility with the machine
- Clearance for grinding
The vise must secure the part firmly without deforming it in the process.
Workholding Chucks
Some forms of Bison chucks may be able to perform grinding processes based on the workpiece geometry and setup of the machine. It will be important to check that the run-out, clamping, speed, balancing, and dimensions are all correct.
Specialised Fixtures
Bison-specific fixtures may be able to be used for grinding parts having odd geometries or parts requiring large-scale production. These fixtures will provide proper positioning but without hampering access to the grinding wheel.
Bison Clamping Tools vs. Dedicated Grinding Fixtures
Bison Chuck or Vise is ideal for the appropriate grinding operation; yet, there are cases where using a special grinding fixture could be an advantage.
| Feature | General Bison Clamping Tool | Dedicated Grinding Fixture |
| Flexibility | High | Usually application-specific |
| Setup | Generally straightforward | May require dedicated setup |
| Repeatability | Good with suitable equipment | Often very high |
| Customisation | Limited | High |
| Production use | Suitable for many jobs | Excellent for repeat production |
| Complex workpieces | May require additional support | Can be designed specifically for the component |
The best choice would depend on how much production is required, tolerances, geometry of the component, and type of grinding process that will be done.
How to Improve Grinding Results With Proper Clamping
Correct workholding is only one part of a successful grinding process, but it can make a significant difference.
Clean the Contact Surfaces
Clean the workpiece and clamping areas of chips, abrasive grit, oil, and any other debris. A tiny piece of debris trapped between the workpiece and fixture could influence the positioning of the workpiece.
Use Appropriate Clamping Pressure
Use enough force to clamp the component without causing it any unnecessary deformation. In the case of thin components, extra support will have to be considered.
Support Long or Thin Workpieces
Long components are prone to bending due to grinding forces. Further support is needed to ensure stability.
Check Alignment
Orientation of the clamp with respect to the machine and grinding process should be correct for the workpiece. Alignment problems may cause poor performance.
Inspect the Workholding Equipment
Before using the workholding device, check for any damage on the jaws, gripping surface, mounting points, and moving parts. A damaged workholding device must not be used for grinding before assessing the problem.
Advantages of Using Appropriate Bison Workholding for Grinding
Good Bison workholding increases the stability, accuracy, and consistency of workpieces during the process. Good workholding decreases the movement of the workpiece and increases the surface finish of the workpiece, and even reduces loading and unloading time. Good workholding increases machining efficiency.
Safety Considerations for Grinding With Bison Clamping Tools
Safety considerations must come into play before each grinding process. Ensure that:
- The clamping system is properly installed.
- The workpiece is tightly secured.
- There is enough clearance space around the grinding wheel.
- The machine is run within its prescribed limits.
- The clamping system is appropriate for its intended purpose.
- The guards are appropriately placed.
- The grinding wheel is checked before grinding.
- Personal protective equipment is put on.
- Grinding waste is cleared away.
- The manufacturer’s guidelines are followed.
It is imperative not to alter the clamping system in such a manner that it affects its construction or operational parameters.
