SuperFinishing

SUPERFINISHING. Metalwork process that improves surface finish.

FRICTION. Simple little word but a word of huge importance when it comes to engines. You don’t want it, however there’s nothing you can do about it. Well that’s not quite true you can sometimes reduce it quite considerably. A smoother surface causes less friction requiring less power to run.

HEAT. Another thing that saps power. Unnecessary friction causes heat. Reducing the friction naturally reduces the heat therefore increasing the power. It’s a win win situation. Superfinishing will guarantee to reduce friction, making everything cooler and intern naturally increase performance.

How much performance? Well we can’t answer that. I suppose it’s what you determine as performance. There’s reliability, a smoother, slicker part with less friction and reduced heat will naturally be more reliable. It kind of speaks for itself, a bit like that word Drag, reduce the Drag increases the slickness (is that a word) which increases the performance.dav

Horse Power. Yep, again we can’t quantify, but we can guarantee it’s there. It takes power throughout the whole drive-train to run and mesh together all your working components. If you can reduce what power is needed to do this you will naturally transfer what was used to drive those components and simply transfer that gained power where you want it.

 

SUPERFINISHING

What is it you might ask? Well its a chemical process that we use. There are various operators doing other things with different media. We do not use any media that may grind, yep grind, another small word but a huge no no in superfinishing. Our media carries the chemicals associated with our process and nothing more. It is so pure and hard and contains absolutely no abrasives of any nature and as said carries the chemical that does the job and delicately rubs the entire surface.

Superfinishing will improve the surface of your component on a microscopic level, improving reliability and durability as hairline cracks and deformations are less likely to appear. Any component that is subject to interaction with another will significantly benefit from the reduced friction characteristics created by Superfinishing. During this process, typically one to four microns of material are removed, depending on the original surface. Critically, this process ensures that the geometry of the part is maintained.

Improvements

  • Reduces wear
  • Reduces stress concentrations
  • Increases fatigue life
  • Increases power efficiency
  • Increases component life
  • Increases power output

Gearboxes must be the most power sapping component within any engine. Rotational behaviour here is greatly improved as well as all the usual benefits of superfinishing. The meshing of the gears will be smoother, quicker and slicker than ever before. Gear selection will be precise and gears will just drop into place with ease.

WHAT CAN BE SUPERFINISHED?

Well virtually anything that rotates within the engine that meshes with another component will benefit from superfinishing. The most obvious gain will be the gearbox. The following will also benefit but this is not a comprehensive list. There is no purpose in doing camchains or bearings. Although the picture beside has bearings fitted, its a demonstration item only.

  • Transmission Gears
  • Gear Boxes
  • Ring Gears
  • Pinion Gears
  • Camshafts
  • Tappets
  • Valve Springs
  • Valves
  • Rocker Arms
  • Crankshafts
  • Connecting Rods
  • Clutch drums
