One of the values of having a machine-oriented process is the convenience of getting the job done in good time and in a very high level of accuracy. More to it, the ease of production is increased to a large degree, thereby making the overall process quite rewarding. A good example to focus on is how to prolong the life of drills and a lot of that is dependent on the sharpening tactics employed:
The Hand Approach
This method is carried out using a block sharpener. Ideally, the process will entail the following:
- Carry out measurements from the extreme point of the outside of the wheel used for grinding, to the top of the table. A measuring tape will work very well for this situation. Measure a distance on the block from your nearest corner and based on this measurement, put appropriate markings on the block.
- Using a saw placed at about 15 degrees, the marked block is placed strategically against the saw fence. The cut is then made from side to side the block to the other, with the mark being positioned along the cut.
- The individual ought to make sure that he or she is facing the angle on the block making sure that the cut is touching the center of the wheel.
- Position the drill bit tip in a way that it faces the grinding wheel to lay the drill bit on the angle. The bit is then slide up the wheel. A careful observation of the bit should reveal that where the bit is touching the wheel, the angles match. In the event that they do not, put the miter saw under the block once again. This process is to be repeated up to the point where the angle of the drill bit is the same as that of the wheel.
- The grinder is then turned on and the bit eased in the wheel to make the bit as sharp as required. The bit can be turned in circles using the individual’s fingers to ensure that one does not lose the block sharpener’s angle. Continue the process until the sharpness of the bit is set at the required level.
The Technical Approach
This approach is centered on the use of the grinder but is dependent on the following pointers:
- The speed at which the grinder is set affects the sharpening process for the bit. Most metals used to make the bits are usually treated to harden the edges with a heat treatment. The sharpening process should be safeguarded to ensure it does not raise the temperatures beyond a certain level, as they will cause the bits to lose the ability to stay sharp.
- The sharpening of bits are more complex and may need a level of skill as they have more complex edges and angular appearances that make them harder to sharpen in the regular way that straight edges would be sharpened.
- The use of dedicated drill sharpeners is a good choice as it allows even the newest individuals to have a fairly easy time in sharpening the bit. It actually holds the bit in the right position as it works on the edges. It is a preferred option for those who use the bit to perform heavy-duty tasks.
- Jigs are also a consideration as they act as special holders that allow the individual to use regular benches in sharpening the bit. They operate by adjusting the angles on the bit and allowing it to exhibit various angles when drilling. It is still effective as it is able to sharpen the bit after just a few sharpening passes.
At the end of the day, despite all these good practices that help in the handling of the bit before and during operation, there is still more that that can be done to ensure that the tool remains effective over a period. Maintenance operations need to include spraying the tool with compressed dry air to keep it clean and guarantee a problem free action of the machine. The various types of drills and drill bits also means that they are not all purpose but rather specific to certain types of materials and certain sizes as well.
