Since balls have a greater surface area per unit weight than rods, they are better suited for fine finishing. The term ball mill is restricted to those having a length to diameter ratio of 1.5 to 1 and less. Ball mills in which the length to diameter ratio is between 3 and 5 are designated tube mills.

Everybodys trying to lose a bit of weight these days, and your pistons are no exception. Why is piston weight important and how can grams be shed without sacrificing strength We explore the process of making pistons lighter.
At 6,500 RPM, a piston changes direction more than 200 times per second. In an engine with a four-inch stroke, that pistons average speed is almost 50 miles per hour, and thats just the average - it spends a considerable amount of time in relative terms sitting almost motionless at the top and bottom of every stroke before being shoved or dragged back in the other direction.
Its easy to look at components like pistons, rods, the crank, and the block as being utterly rigid when theyre laid out in the assembly room, but the forces that act on them in operation are so far beyond our ability to intuitively understand that its hard to get a feel for how theyre flexing and moving in operation.nbsp
Under compression, when parts are designed correctly, everything is happy and holds itself together, DiBlasi explains. Heavy weight really can make an impact when the mass becomes further and further from the centerline of the crankshaft.
The Basis Weight is defined as the weight of 500 sheets of paper in its basic unit uncut size, which means before being cut to Letter size or Legal size, the paper is weighed and categorized. The most common sizes, some of which you may recognize, are Bond, Text, Book, Cover, Index and Tag.
Per DiBlasi, The more weight you can pull out of the rod and piston assembly, the less stress you put on the bearings and journals. When revving engines high, the load and speeds can do damage at an exponential rate. Every gram makes a huge difference at that point. An extremely heavy piston also pushes the limits of the rod bolts. The piston on its way back up to TDC will be doing everything it can to keep moving in that direction, and the rod bolts are the only thing in place to stop that.
In some circumstances, like engines running high boost or a lot of nitrous, theres no alternative to having extra mass in the piston in order to provide enough of a heat sink to prevent detonation and supply a broad enough path for that heat energy to make its way out of the piston and into the cylinder walls, and eventually the cooling system. But without those special conditions, lighter is going to be better.
With these factors in mind, how can pistons go on a diet without sacrificing strength Some of it comes down to genetics - how the piston is manufactured. The two common methods for mass-produced pistons are casting, where molten aluminum is poured into a mold, and forging, where an aluminum blank is heated, then shaped in a die under immense pressure. There are pros and cons to each method in terms of strength, the materials used, and of course price, and one isnt necessarily better than the other for every application.

To calculate the gsm of your material, simply fill out the fields above and select the correct units. Its free and easy to use This calculation is commonly used for nonwoven materials, paper, plastic and other thin materials. The most common way to measure GSM is using a scale and a ruler, but there are sometimes other methods needed for industrial processes.

Roll Weight X Area of Basic Size X 500 Basis Weight X Roll Width X 12 Estimated Linear Footage
Finding and marking the exact center of a small metal rod or dowel ismore difficultthan finding the center of a larger circle. I recently wanted tomark the center of a 1 long x 38 diameter brass rod, thendrill a 18 concentric hole the entire length. Yes, just a brass rod with a hole down the center. A professional machinist with a metal working lathe might have no problem with this, but for the average garage shop guy me it was no easy task. I learned a few tricks and made a jig that made the job easier and the results better.
Basis Weight. To convert basis weight of a given standard size of paper to grams per square meter, multiply its basis weight by 1406.5 and divide the results by the square area of its basic size.
The classic method of finding the center of a round object is to use a center finder head attached to a standard metal rule, such as used in a combination square. You hold the round item in the V-notch and scribe a fine line. That line is a diameter of the circle. Rotate the piece, and scribe another line. Where the two lines intersect is the center. Easy and accurate for large circles say over 1 diameter, not so easy for a 38 rod. Forget about using a pencil use a sharp knife point, like an Exacto knife. Even with a sharp knife, the line can be a bit off center.
Use a Forstner or brad point drill bit the same size as the rod. The point at the center will be reliably dead center. Place the rod and drill bit on a hard flat surface, andwith the point of the bit scribe a couple of lines on the rod end. Where the lines intersect will be the center.

This jig will make it possible to drill your concentric hole straight down the axis of the rod.
Start with a block of softwood scrap, like the piece of 2x4 in the photo, clamped to the table of a drill press. Then drill a hole of the same diameter as the rod through the wood block38 diameter in this example. Remove the drill bit and insert the rod into the hole you just drilled. It should be a snug fit. It is best to not remove the block leaving it securely clamped will assure that everything remains aligned.
Here is a method which I think is much less prone to errors. Required thick block of wood, a transfer punch with a small diameter compared to the rod, a drill bit bit the same diameter as the transfer punch, and a drill the same diameter as the rod.
