What is a diamond honed stone?

Honing stone with fine grain diamond is used for finish honing. The purpose is that grind the cylinder hole to the meet the accuracy requirements about tolerance of shape and size. At this time, there are deep scratches on the surface of the workpiece in the finish honing process. These scratches are grooves for storing lubricating oil during the working process of the engine.

What happens to diamond abrasive grains in honing?

In the honing process, diamond abrasive grains break up and fall off under the action of external force. Abrasive grains automatically reveal new cutting edges and continue to participate in cutting, so that the cutting process continues to work. 4.

What is the abrasive used in honing stone?

The abrasive of honing stone has an important influence on the processing quality and efficiency of a cylinder hole. Besides directly affecting the macroscopic geometric accuracy of the cylinder hole, it also affects the microscopic surface structure and the distribution of lubricating oil grooves. Alumina, silicon carbide, CBN, and synthetic diamond are used as abrasives for various honing stones.

Why are there air holes in diamond honing stones?

A: There are a lot of air holes in the internal structure of sintered diamond cylinder honing stones in order to stock the chips in the honing process.

What is honing in machining?

Honing machining process is formed by very sharper grinding grains which are exposed on the surface of the stones. With the advancing of the process, the grinding grains on the surface of other stones gradually fall off. The grinding grains in the conventional ceramics or diamond stones gradually expose and then honing.

How is honing different from general machining?

What has changed in honing cylinder blocks?

The basics of honing cylinder blocks hasn’t changed much in recent years, but what has changed are the type of abrasives being used by many engine builders.

What kind of stone do engine builders use?

But in recent years, a growing number of performance engine builders and custom engine builders have started using the same type of honing stones that production engine rebuilders and OEMs use: diamond abrasives.

Why is cylinder bore important?

Cylinder bore quality plays a huge role in reducing friction and blowby for improved engine performance and durability. Better bore geometry also contributes to better sealing and more usable power. Riley says a lot of performance engine builders are hot honing their blocks to more accurately simulate actual running conditions. They also use torque plates when honing (some with simulated manifolds to further stress the block), and may even bolt a bellhousing to the block to reproduce the stresses and loads the block will experience in a vehicle.

How many cylinder bores does a V8 block have?

Typically, a set of conventional vitrified honing stones might do up to 30 V8 blocks (240 to 260 cylinder bores) before they’re worn out and have to be replaced. A set of metal bond diamond honing stones, on the other hand, might do as many as 1500 V8 engine blocks (12,000 cylinder bores) before they have to be replaced. That’s a huge difference.

Which is better for portable honing: diamonds or abrasives?

As for portable honing equipment, conventional abrasives are the better choice for this type of application. Most of those we spoke with say diamonds require too much pressure for portable honing equipment.

What is a bristle hone?

Bristle style soft hones consist of mono-filament strands that are extrude-molded with a fine abrasive material embedded in the strands. The filaments can be mounted in different types of holders or brushes that can be used with portable or automatic honing equipment.

What is the best material for honing?

Diamond has long been the material of choice for high speed, high volume honing applications because of its excellent wear characteristics. Stone life depends on the hardness of the abrasive, the hardness of the substrate that holds the abrasives, the hardness of the engine block, honing speed, load and the amount of metal that’s removed. Diamond is the hardest natural substance known, so it can hold a cutting edge much longer than a conventional abrasive. This means the bond that holds the diamonds can also be harder because it doesn’t have to wear away as quickly to expose fresh stones on the surface.

How to finish an aluminum engine block?

To produce a good finish in a hypereutectic aluminum engine block with no liners, you have to remove a small amount of aluminum from the bores to expose the hard silicon particles. The silicon particles should protrude about .00002˝ to .00004˝ above the surface and cover about 80 percent of the bore area. This will provide a good wear surface for the rings to ride against the hard silicon particles and not the aluminum bore.

What is the oil consumption concern on a 2.4L engine?

GM tech service bulletin 13-06-01-003G dated February 2015 covers “excessive oil consumption concerns” on 2.4L engines in 2010 to 2013 models. GM says that if the engine is using more than a quart of oil every 2,000 miles, the rings and pistons need to be replaced. The bulletin also states that the bores in these engines do NOT need to be honed or deglazed if crosshatch is still visible and there is no excessive wear or other damage.

Why did aluminum block engines leak oil?

The oil consumption problem in these first generation hypereutectic aluminum blocks was also attributed to a poor cylinder head design that allowed too much oil to leak down the valve guides. The engines also had a tendency to overheat, warp and crack.

Why do you need a ring seal on an aluminum block?

Proper bore finish and ring seal are absolutely essential to prevent excessive oil consumption, comebacks and unhappy customers. Whether you are honing an aluminum block with iron liners, a hypereutectic aluminum block with no liners, or an aluminum block with some type of hard nickel coating in the cylinders (such as Nikasil, Alusil, etc.), you have to know what you’re working with so you can use the appropriate honing procedures that will achieve the desired bore finish.

Why are cylinder bores acid etched?

The cylinder bores are then acid etched to remove just enough aluminum from the surface to expose some of the hard silicon particles. When done correctly, the exposed silicon particles provide a wear-resistant surface for the piston rings. But the Vega engine cylinders weren’t always finished properly at the factory.

What is a 2.4L engine?

Another late-model aluminum engine with cast-in-place iron liners is the 2.4L four-cylinder that GM has used in the Chevy Equinox, GMC Terrain and Buick LaCrosse, Regal and Verano. Like the Chevy Vega engines of the 1970s, the 2.4L also has a thirst for oil. GM says the problem isn’t the bore finish in the cylinders, but a ring wear problem caused by clogging of the Positive Crankcase Ventilation system, oil dilution and oil breakdown (a good reason why motorists should change their oil more often than indicated by their vehicle’s “Oil Life Monitor” service light).

What cars have aluminum blocks?

Manufacturers who produce “linerless” hypereutectic aluminum blocks today include Audi, BMW, Honda, Mercedes, Porsche, Volkswagen, Volvo, and Yamaha. Most late-model engines have aluminum blocks to save weight, including most of the familiar domestic V8s such as Chevy LS, Ford 4.6L modular and 5.0L Coyote, and Chrysler 5.7L and 6.1L Hemi.
