Anyone know the process commonly used to diamond cut cylinder fins ? I'm thinking about maybe doing it on some valve covers and air cleaner for my Buick engine. In my head it would either look relly cool or really overdoen. Anyway I'm curious about the process. If'n you don't know what I'm talking about : Last ones a nice job (IMG:style_emoticons/default/rolleyes.gif)

It's almost like knurling.....
Is there a seam or small area of difference at some point? Glue some cubic zirconium.... er I mean diamonds around the edges for a little more bling..... Kinda like that car that was sporting the 20 something inch wheels with the sparklies.... If it's for management, I've often hit products with some glue and a bag of glitter.... They start salivating...... Ken |

looks to me like you come at it sideways at a 60 degree angle and run down one side of the fin first to create the triangles....then turn it over and reverse the same process, just from the other side.
this would create the peek. In looking closely its really two triangles that are concaved. Looks like a serious amount of time involved....ouch. It might look cool on my tranny though......hmmmm Painted with all the ribs cut that way....hmmm Rich |

They probably wrote a CNC program to rotate the cyliner and to move the cutter in and out. Turn it on, come back later- much later......
But first, you must either scan the cylinder to obtain a cloudmap, or measure and build a CAD model of the fin profilles and spacing. Whatever, it ain't cheep like glue and glitter.... Ken |

Looks expensive/time consuming!
Sure is pretty though. I could see it being done on the cylinders of a harley or other such engine where you can actually see the cylinders. Why is the base of that last cylinder broken? |

Why is the base of that last cylinder broken? is this just bling or does it disapate heat? 99 % bling. Technically it does increase the surface area of the fin but no deeper then the cuts are, I doubt it does much extra cooling |

What I am thinking is doing this to all of these finned edges....then again I doubt I'll ever have that kind of spare change......to believe in (IMG:style_emoticons/default/hide.gif)

Heres one way:
http://www.patentstorm.us/patents/6626134/fulltext.html And an excerpt of the patent text: The engraving of edge surface 32 is preferably accomplished using a hand-held, rotating diamond head cutter (not shown). Excellent results have in particular been obtained using the following equipment: a Foredom(.RTM. Micro Model FM 1000 engraver; a Foredom.RTM. Handpiece Model 0183; a Diamond flywheel in any of the following sizes: 120, 125, 130, 135, 140, 145, 150, 155, 160, 165, and 180; and a Diamond cutting member, size 3 mm. The diamond cutting member is also referred to as a burr and an exemplary cutting member 50 having a diamond cutting element 52 mounted on the periphery of a head 54 attached to a stem, or shaft, 56 is shown in FIG. 12 of the drawings. The burr preferably exhibits a 120 degree "V" shape or profile as viewed in FIG. 12. Cutting member 50 upon being installed in a handpiece capable of rotating the cutting member at a rotational speed typically exceeding 10,000 rpm is used to engrave the edge of a cooling fin to create the preferred vertically stacked rows of elongated concavities being angled (e.g. acutely angled) with respect to the horizontal axis 33 of surface edge 32. Contiguous, or abutting cuts or incisions are made into surface edge 32 and the center of each engraving is deeper than the ends of the engraving which are located proximate the edges of the fin, i.e. the depth of the engraving diminishes from the center of the engraving as it tapers off to the edge of the fin. Thus, a small part of the original edge of the fin will often remain. The axis 33 of the cutting member is preferably placed at an angle of 45 degrees with respect to the horizontal axis of cooling fin 18, but may be placed an any angle when actually engraving each intagliated portion 40. Chamfer 58 shown positioned adjacent diamond cutting element 52 is to ensure diamond cutting element 52 has plenty of approach clearance when engaging edge surfaces of cooling fins when engraving is being conducted. There are many alternative methods that may be employed to create a surface edge on a cooling fin to have the desired characteristics of the present invention as described above. Namely, a multi-axis computer numerically controlled machining center, also referred to as a CNC machine, may be programmed to create the preferred intagliated surface edge to a depth ranging upward of 3 mm, or to any other suitable depth. Additionally, the fins of the engine component may be cast so as to be provided with an intagliated surface edge and the surface edge being polished, chemically etched, shot peened, or subjected to any suitable surface treatment known within the art to provide a desired level surface finish, or brightness. Moreover, other machines and surface forming and modifying techniques known within the art may also be employed to provide edge surfaces to cooling fins in accordance with the present invention. Other possible embodiments of the engraving are shown in FIGS. 13-18. FIG. 13 shows a combination of ovals 20 that are essentially in the shape of a Marquis-style diamond, that are cut into surface edge of a fin. Thus, FIG. 13 shows an end-to-end (or horizontal) combination of ovals 20, FIG. 14 shows a side-by-side (or vertical) combination of ovals 20, FIG. 15 shows an angled, side-by-side (or vertical right angled) combination of ovals 20; FIG. 16 shows an angled, side-by-side (or vertical left angled) combination of ovals 20; FIG. 17 shows a plurality of x-shaped combinations of ovals 20; and FIG. 18 shows a plurality of inverted v-shaped combinations of ovals 20. Any combination of the designs shown in FIGS. 13-18 may be employed on a particular component of an engine 12 or on different components of the engine 12. |
