摘要： The subject of the invention is a unit for surface treatment of top layers, especially of metal, which is used for the treatment of top layers of working surfaces of machine parts, and especially for placement of coatings of micro- and nanometric solid greases in the unevenness of the surfaces of extrusion punches and on sliding guides of machine tools. Characterised in that the ram being a hammer (2) with a ball-shaped working area, connected with a piezoelectric actuator Q), which is driven by a high frequency voltage generator with a frequency changeable within the range of 10 Hz to 1000 Hz and a relative movement of the hammer (2) in relation to the treated material (3) along the acting line within the range of 0.05 to 5.0 mm.

摘要： Tooling and a method of employing tooling (90, 130) to produce beneficial stress waves in a substrate (132) to provide high fatigue life structures. Stress waves (159, 152) are provided to work a substrate, causing dimples (170) in the workpiece, along a uniform pressure profile in the workpiece. By use of the method, uniform beneficial residual stress is provided at surface and midplane apertures in a workpiece, so as to improve overall fatigue life. An improved tool shape (92) is described, having a smooth curve, rather than a flat punch. Also, the use of a consumable wafer (W) provides additional uniform stress profile benefits.

摘要： The rate of impact between the peening elements (14) and an internal surface (26) of a hollow part (12) is a function of the vibration frequency, and there is a cut-off frequency at which a hollow part (12) can vibrate and induce repeated impact between its internal surface (26) and the peening elements (14) because the rate of impact becomes erratic and loses its cyclical nature as the vibration frequency deviates from the cut-off frequency. The present invention provides a method for determining the cut-off frequency at which a hollow part can vibrate and maintain the repetitive nature of the impact between its internal surface and the peening elements. Such a method requires a peening element speed limit ratio, which is the ratio of the velocity of the hollow part compared to the velocity of the peening element above which the rate of impact begins to become erratic and lose its cyclical nature. The present invention utilizes the peening element speed limit ratio to determine the frequency at which to vibrate the hollow part when peening its internal surface so as to and maintain repeated impact between it and the peening elements.

摘要： The burnishing head for hard disk processing includes a solid body having generally rectangular surfaces, including an upper surface, a burnishing pad surface, a front surface, a rear surface and two side surfaces. A plurality of burnishing pads are disposed upon the burnishing pad surface. The pads are shaped such that each pad has a burnishing edge that is generally parallel to said front surface and therefore orthogonal to the direction of media travel. The burnishing pads are preferably configured such that two frontward leading pads are disposed proximate the front surface in a spaced apart relationship and one leading middle pad is disposed rearwardly of the two frontward leading pads and generally between the two frontward leading pads. Two rear pads are disposed generally rearwardly of the leading middle pad in a spaced apart relationship, and one rearward pad is disposed rearwardly of the two rear pads and generally between the two rear pads. In the preferred embodiment the pads are generally triangular in shape and the outer surface of the leading and rearward pads may be tapered. The method for manufacturing the burnishing head, includes the steps of making a series of parallel cuts in a surface of a solid body of material. The burnishing pads result from material that remains following the cuts.

摘要： An integrated, unitary micro-burnishing head structure for use with the surface of rigid magnetic recording media. In one type of embodiment, the proposed head structure includes a single elongate flexure body to one end of which is joined a media-contacting abrader head which may take any one of several different preferred shapes. In another embodiment, plural elongate flexure bodies are disposed in a comb-like array carrying abrader heads at one set of free ends, and joined adjacent their opposite ends through a common joinder structure.

摘要： A method of reducing crack propagation in an airfoil (22) includes: providing an airfoil (22) having a root (36) spaced apart from a tip (34), spaced-apart leading and trailing edges (30, 32), a suction side (40) extending from the leading edge (30) to the trailing edge (32), and an opposed pressure side (38) extending from the leading edge (30) and the trailing edge (32), supporting the airfoil (22) against bending loads. The airfoil (22) is burnished using a burnishing element (42), so as to create at least one burnished section (68) of residual compressive stress. The at least one burnished section (68) is located adjacent the leading edge (30) and spaced from the leading edge (30) by an offset distance selected so as to avoid deformation of the leading edge (30).
