Research stone diamond bit drilling parameters affect its surface temperature

 Drilling in stone, because of relatively high speed movement between the diamond drill and stone complex tribological phenomena arising in the contact interface. Friction between diamond drill and stone, as the stone poor thermal conductivity, most of the heat transferred diamond segment, making diamond drill surface temperature, resulting in diamond graphite, diamond cutting capacity reduced, which leads to the bit matrix  thermal polishing pads for granite  fatigue, lower strength and stiffness, increased noise when processing stone, increased vibration, reduce bit life, serious diamond head off, causing injury to the operator, but also affect the processing quality and efficiency. Research diamond bit drilling parameters affecting its surface temperature to identify factors that influence the relationship between surface temperature and the law, determine a reasonable processing parameters, help to improve the diamond drill bit life and reduce processing costs, improve processing quality.
  Experimental conditions are diamond segments using a Cu powder, a diamond particle size of 60 to 80 mesh, using pressing sintering method, the welding head in the high speed steel cylinder. Diamond drill diameter φ37mm, high-5.6mm, width 2mm, base diameter φ35.6mm, height 45mm. Processing equipment used XK5032C type CNC milling machine, the device implements the X axis, automatic feed three directions Y and Z axes, spindle cooling method using water-cooled. The temperature measured with an infrared wood band saw blades  temperature measuring surface of the tool, the measurement temperature range of -50 ~ 650 ℃. Direct l2 ℃ measured at room temperature conditions. Stone were selected marble, sandstone and granite. This experiment studies the spindle speed, feed rate and stone impact performance parameters such as surface temperature of the diamond drill bit. Experiment was carried out under dry cutting conditions, machining state. Results of impact 3.1 feed rate on temperature
 When processing stone diamond drill, impact drill surface temperature of many parameters, including diamond properties, performance bond, stone physical and mechanical properties, processing parameters, cooling parameters. Effect on the surface temperature of the diamond drill bit experimental study of stone processing parameters and performance. Figure 2 is the spindle speed is 300r/min, the feed rate was 10mm/min, 15mm/min, 20mm/min, 25mm/min, when the surface temperature of the pre-drill drilling marble drilling time curve. As can be seen in Figure 2, in the four kinds of conditions of feed rate, the surface temperature of the diamond drill bits are increased with the increase of the processing time. In the early stage of diamond tools manufacturer  processing, the temperature increases relatively slowly, when the processing time exceeds 4s, sharp increase in temperature. When the processing time reaches 10s, the diamond drill is the initial surface temperature 5 times. Figure 3 feed rate versus temperature curve for the processing of marble. From the figure can be seen in the feed rate l0 ~ 20mm/min the temperature rises slowly, the feed rate of 20 ~ 30mm/min, the temperature rise is most obvious, the most heat in this interval drills stone processing generated. As the drilling process, the diamond drill bit with a large stone surface friction, resulting in diamond drill surface temperature rise. Due to the low thermal conductivity of marble, and a high thermal conductivity of the tool, a large part of the heat conducted to the diamond drill bit, diamond drill causes the surface temperature. Since the feed rate increases, the cutting face of the contact per unit time increases, the number of cutter contact with the stone, the surface temperature increases.

After granulation powder having a particle diameter of a large particle size than the original powder, each particle is surrounded by the number of particles may be exposed to reduced, so the adhesion, cohesion and mutual friction greatly reduced, thereby to improve and increase the particulate material mobility.
2. Diamond powder and reducing segregation and aggregation, more uniform distribution, improving the performance of products. Granulation process prior to powder, diamond mixed with a binder, and then add solvent mixing and granulation wetting again, every single diamond powder wrapped in quilts are then cold pressing and sintering, thus preventing polishing pads for granite  segregation and diamond powder aggregation, thereby increasing the sintering properties of products, uniformity and stability of the product.
3. Improve the accuracy of the product size and weight, since the mixed powder to improve flowability, the powder products more uniform loading of the cold, cold products, improve the accuracy of the geometric dimensions and weight. This repression shaped products, sandwiches, laser welding blade tips and the transition head better.
4. Reducing the loss of cold mold. Since the metal grinding wheel  powder fluidity, diamond powder parcels were distributed more evenly, so the cold mold loss reduction, die life by 50 or more.
5. Improve the efficiency of the process cold and economy, in order to achieve the cold automated production to create the conditions. As the improvement of powder flowability, die life, so that ordinary cold press automatic weighing more efficient, making the volume of the adoption of automatic cold press possible. A foreign company 32VPM volumetric cold press, according to the head design, the operating parameters entered into the computer, basically metal grinding wheel  do not care personnel, automatic production. Granulation and displacement using cold press, the head is reduced to suppress the time from 32S 10S; die life by a 12,000 increase to 25,000; cold reduced costs from $ 0.35 to $ 0.11.
