How to extend the service life of tire shredder tools

Solution:

1. Proper control of cutting force and cutting speed

Appropriately controlling the cutting force and cutting speed of the tire shredder tool is also one of the effective means to reduce the temperature of the processing area and extend the service life of the cutting fluid. When machining difficult-to-machine materials, precision-sheared tire shredder cutting edges are generally used, and the cutting depth and cutting width should not be too large. When selecting the cutting line speed, it should be considered according to different material types, part structures, and processing equipment. In general, if the processing material is nickel-based alloy, the line speed should be controlled at 20 to 50 meters per minute; the processing material is For titanium alloys, the line speed should be controlled at 30 to 110 meters per minute; the processing material is PH stainless steel, and the line speed should be controlled at a range of 50 to 120 meters per minute.

2. Choose a reasonable cutting method

For difficult-to-machine materials, the choice of different cutting methods has great differences in the damage to the cutting fluid. No matter which cutting method is selected, the principle is the same, that is to reduce the cutting force as much as possible and reduce the temperature of the cutting area. The tire recycling machine can reduce the cutting area to a large extent, so that the actual cutting angle of the cutting fluid can be reduced, thereby extending the heat dissipation time of each tooth of the tire recycling machine and reducing the cutting temperature; using spiral interpolation It can make the cutting amount of each tooth relatively uniform, avoiding the concentration of cutting force on a few teeth and accelerating wear.This effect is more obvious at the corners. The feed effectively reduces the cutting force, which results in less cutting heat during processing and lower temperature in the processing area.

3. Guarantee timely and effective chip breaking

In metal processing, a large amount of cutting heat is generally generated on the cutting shoulder. If the chip length can be controlled to ensure timely and effective chip breaking, this part of the cutting heat can be taken away by the chip, so chip breaking controls the cutting temperature. An effective way. When processing difficult-to-machine materials, in the roughing process, as long as the rigidity of the processing system allows, chip breaking should be generated during the entire processing process. At the same time, use cutting fluid with good sedimentation performance to settle and discharge the cutting chips. Do not allow the cutting chips to rub against the surface of the workpiece. General-purpose cutting fluid SCC730ASCC730A water-based environmental-friendly cutting fluid can be selected from special high-performance additives, rust inhibitors and other additives. It is a high-performance multi-purpose grinding fluid. When mixed with water, it can form a stable transparent solution. This product has good sedimentation, lubricity, rust prevention, cooling and cleaning properties. It has strong anti-microbial decomposition ability, and can still maintain its stability under different water hardness conditions.
