TURBO-FINISH TECHNOLOGY:
(January 16, 2017, Barre, Massachusetts USA) The technology is currently used in the United States to deburr and contour the edges of complex parts, and to create isotropic surface finishes essential in finishing many complex parts. The technology is inherently simple, and thus enjoys the attributes of reliability and repeatability of such simpler technologies. However, it accomplishes results on very complex parts that often cannot be achieved reliably by other, much more complex, processes.
The technology involves a fluidized bed of media in which the part to be processes is rotated. A wide variety of differing results may be achieved by varying the process parameters (media, process time, rotational speed etc.). Process results can be controlled within microns, are programmable, and are totally repeatable, providing unequaled process quality control. The process is dry, and involves no chemicals or environmentally unfriendly materials.
A wide variety of parts that are non-rotational in character can also be processed. This is done by attaching them to “fixture wheels” that exposes the critical part edges and surfaces to the vector of rotation through the abrasive fluidized mass.
Specialized soft polishing media can be utilized in post abrasive finishing operations to produce low Ra polished surfaces. This is especially effective when a sequence of operations, utilizing successively finer abrasive materials, is specified. Turbo Finish can achieve these results on complex parts which cannot be processed by any other technique. Edge/Surface Finishing and Surface Integrity Applications This technology has been demonstrated to successfully impart compressive stresses into parts in a fashion similar to shot peening. Turbo Finish shot peening is achieved through the energy of the rotating part, and not by energy added to thousands of small steel balls. This results in a much more efficient use of energy, a much cleaner and quieter process, and a much longer life of the machine involved. Additionally, both deburring and shot peening can be done in a single machine.
The method is also capable of producing surface conditions at these critical edge areas that contribute to increased service life and functionality of parts that are severely stressed in service. Among these are:
The creation of isotropic surfaces. The linear characteristics of ground or machined surface patterns can be modified into one in which surface tracks developed by abrasive action have a random (isotropic) non-linear nature, minimizing potential crack propagation points. The isotropic surface greatly enhances oil retention, and improved adhesion of plating and other finishes. This surface also results in holding oil uniformly for reduced friction of contacting parts.
The replacement of positively skewed surface profiles with negative or neutral skews. The basic character of the surface profile can be changed from one having a positive skew in which surface peaks were the predominant surface feature, to a neutral or negatively skewed surface. These types of plateaued surfaces have much higher bearing load ratios than their positively skewed counterparts, and can increase the service life of components or tools in high wear situations dramatically.
The promotion of stress equilibrium and uniformity. Almost all common machining and manual finishing methods produce uneven stress hot spots in machined parts. This occurs because of the rapid rise and fall of temperature on metal surfaces at the tool or wheel point of contact. Turbo Finish can promote a stress equilibrium or uniformity through out the entire part. Turbo Finish is thus a corrective after process for critical parts that suffer from these machining related surface integrity problems.
The synergistic effects of the above three features can add significant value to the service life, performance and functionality of parts that far exceeds the value of the improvements to fit, function and aesthetics commonly associated with other mechanical or mass finishing processes
