Deep hole honing is the primary way of finishing, the main problems existing now are the low efficiency, high surface roughness, especially in the processing of difficult to cut materials. In this study, the test is on the titanium alloy and uses the self-developed ultrasonic vibration honing equipment. The results show that in the same conditions, the ultrasonic vibration in deep-hole honing can improve the efficiency about 1 times, and meanwhile the surface roughness can reach below 0.8μm, the oilstone is uneasy to block, and the technical effects are better than traditional honing process.

Research Results

Based on the machining principle of ultrasonic vibration lapping, the surface roughness characteristics of plastic difficult-to-machine titanium alloys are studied through experiments using self-developed ultrasonic vibration lapping device. And the effects of workpiece speed, ultrasonic amplitude and grain size on surface roughness were researched by using single-factor testing way. The research results show that surface roughness is decreased to a certain extent for the assistance of ultrasonic vibration. The corresponding results provide certain reference value for the optimization of processing parameter in ultrasonic vibration lapping.

The method of imparting ultrasonic vibration to the cutting tool is known to improve the shape accuracy and finished surface roughness. However, a uniform evaluation of this function in drilling has not been achieved, and the cutting process cannot be checked from the outside. The aim of this study is to investigate the cutting characteristics in deep hole drilling when an ultrasonic vibrator on the table of a machining center provides vibration with a frequency of 20 kHz to the work piece. The ultrasonic vibrations in this system reach the maximum amplitude in the center of the work material. We evaluated the change in finished surface roughness between the section where drilling starts to the point of maximum amplitude with ultrasonic vibration. The main cutting conditions are as follows: cutting speed (V) 12.6 (mm/min); feed rate (s) 30, 60 (mm/rev); depth of cut (t) = 32 (mm); work material, tool steel; cutting tool material, HSS; point angle (σ) 118 (°); and drill diameter (φ) 4 (mm). Lubricant powder was also added to clarify the cutting effect, and compared the condition in which there was no ultrasonic vibration. The results showed that surface roughness at the point of maximum amplitude was better than that with no vibration.

In the deep-hole boring process on pure niobium tube, there exist some problems including serious tool wear, tough chips, and poor surface quality. In order to bore high-quality deep holes on rolled niobium tube, the cutting tool structure and boring process parameters suitable for machining rolled niobium tube were designed and two experimental schemes were proposed. The results showed that the geometric parameters of the cutting tool and process parameters have important influences on the tool wear, chip morphologies, hole-axis deflection, and hole surface roughness. By adjusting the geometric parameters of the cutting tool and boring process parameters, reasonable geometric parameters of the cutting tool and boring process parameters were obtained.

When difficult-to-machine materials are drilled, chips are produced, and these chips are difficult to control during the drilling process. Due to the limitations of conventional drilling, materials are drilled by ultrasonic-vibration-assisted technology. In this paper, the kinematics of ultrasonic-vibration-assisted drilling are first analyzed and the relevant equations are established. The characteristic thicknesses of chips are then studied, and the drilling paths for different phases and thicknesses of the chips are analyzed. The condition of complete geometric chipbreaking in the ultrasonic-vibration-assisted drilling process is examined, and a regional map of chipbreaking is presented, which in theory allows chips to be controlled. Chips produced in ultrasonic-vibration-assisted drilling with different parameters are compared in a series of experiments. The chipbreaking condition is studied in more detail, and the chips produced by drilling difficult-to-machine materials are effectively controlled. Furthermore, the results of this study show that a reasonable selection of parametric variables in ultrasonic-vibration-assisted drilling results in thin and smooth chips, less tool wear, and superior surface roughness.
