Techniques for Improved Cutting Performance

By: Scott Bahr

In August, we wrote an article titled Considerations for Cutting Assembly Design and Service in which we discussed how we best serve our clients by conducting a thorough needs assessment. There are several mechanical cutting methods. At Bit Service, we consider the method and design aspects for the best possible cutting assembly to suit clients' particular needs. It is essential to consider the design of bits and maintenance requirements carefully. This week, we will be building on the information we shared in our August article by looking at three techniques we use to improve cutting performance. 

Optimizing machine operations

To improve performance, the first step to make the most out of underground mining equipment is ensuring machine operators are familiar and proficient with the machine they are using. Bit Service dedicates many hours working with clients and their teams to optimize the production process further. While learning the nuance of mining machines from scratch can be a big order, we have staff with years of expertise working with production who can help by assisting and making recommendations to improve operating procedures and efficiency.

Preventative maintenance 

When working with specialized machinery, it is critical to keep up with preventative maintenance to ensure it can operate at its highest function. The cutting assemblies we at Bit Service design and manufacture for our clients are crafted with tactful design considerations in mind and are unique from others on the market. To keep up with prime functionality, we have a specialized team to conduct preventative maintenance. We offer inspection, refurbishing and repair of cutting assemblies for roadheaders, continuous miners and boring machines. 

Condition of cutting bits and bit holders

Cutting bits are often the front line of mining operations. It is essential to make sure the bits themselves are in prime working condition so the machine can be as efficient as possible. Regular maintenance of bits helps ensure the most efficient return on resources.

Optimization of the cutting assembly itself is done through revised bit positioning, bit spacing, and the cutting assembly's generalized layout. We do so to optimize the rate of penetration and the size of the cut ore to be able to maximize the efficiency of the machine. After optimizing different elements, our final step is further assessment of the entire assembly's working order and efficiency.
