In spheroidal graphite iron GGG40. An identical test tool was addition, with steel machining it can come to fringe zone applied for completely dry machining, MQL machining and hardening of the hole wall, making follow-up operations machining with air cooling. such as tapping or reaming more difficult. The test tool was a diameter 8.5 mm drill, optimized for AIR In the second test, the heat measured MQL. The drilling depth was at the point of the drill with internal air 42.00 mm.The cutting rates were cooling was 196 C, evidence that the vc = 130 m/min and f = 0.26 mm/ flow of air dissipates a considerable rev. amount of the generated heat. In addition, chip evacuation was A thermo-graphic camera recorded the temperature at the considerably improved, confirming point during the return stroke from the hole. A machining sequence of seven consecutive drilling operations was re- that in contrast to completely dry machining the spiral flute corded for this purpose. From the first to the fifth hole a of a drilling tool alone is not sufficient for an optimal chip temperature increase at the point was recorded, however, evacuation. following the fifth hole the maximum temperature at the point during the withdrawal process did not change (quasi MQL Under similar test conditions, the stationary condition). For this reason the temperature of heat measured at the point of the the drill was always recorded following the seventh hole. drill applied with MQL, i.e. air mixed with small quantities of oil, Consequently, this temperature is lower than that occurring was only 145 C. An oil volume of at the point of the drill during the cutting process. only 30 ml/h could not be regarded Measuring with thermal elements below the face and just a major contributing factor in the behind the cutting lip have shown that temperatures up to 900 C can occur in this area. However, the temperature cooling process, therefore, it must be presumed that the comparison carried out in this test is admissible because small quantities of oil mixed with air caused a considerable the measurement was always taken at the same point in reduction in friction. It also confirms, in contrast to pure air time. cooling, a further increase in speed of chip evacuation. The lower chip temperature, in comparison to pure air cooling, is further clear evidence of oil reaching the effective area and improving chip evacuation from the face thanks to improved friction characteristics. WITHOUT During a completely dry Dry machining Technical Dry machining dispenses with the use of coolant entirely application, the temperature resulting in savings in various areas. For example, less chip at the point of the drill expensive tools without internal coolant ducts can be applied. Furthermore, machines and tool holders suffice tool reached a maximum 431 C. without elaborate coolant delivery techniques and obviously there are no longer the costs of coolant and their disposal. work- This temperature does not Coolant does not have to be removed from components piece and the surrounding machine area. pose a particular problem for Without lubrication, the heat generated during the machining modern tool materials and hard process must be kept to a minimum and dissipated solely via the chip. Otherwise, tool and work piece are exposed to coatings, even a completely dry excessive heat, resulting in increased wear to the tool and hardening of the hole surface in the work piece. Suitable application offers process reliability. coatings can prevent overheating of the tool. However, excessive heat to the work piece can only be achieved by a However, the diffusion and adhesion wear mechanisms both accelerate at higher temperature levels, which in turn reduces tool life. Furthermore, an increased level of heat can lead to a thermal expansion of the work piece, that in turn can jeopardise the close tolerance dimensions if the 393 [email protected] www.guhring-tools.ru
