### What is Deep Hole Drilling

A deep hole is defined by its depthtodiameter ratio (D:d), and typically holes greater than 10:1 are considered deep holes. Deep hole drilling into metal has a range of appliions across several industries, with its origins tracing back to the need for straighter, more accurate gun barrels, and expanding as other industries integrated deep hole drilling processes to improve their own ...

Apr 10, 2012 · On lathes, think about the longest part: the barrel. Turning long slender parts like barrels is not as simple as some think. Rigidity is hard to get out of a piece of material with that high a l:d ratio. So, a quality setup will include a good follower rest, along with a conventional steady rest. Many prefer ball bearing rests, myself included.

### Pressure Loss from Fittings

The equivalent length method (L/D ratio) allows the user to describe the pressure drop through a fitting as a length of pipe. In theory the pressure drop through the fitting is equivalent to the pressure lost through a certain length of piping at that corresponding flow rate. The most accurate way to use this method is when tabulated data is ...

### Taper Calculations

Taper Calculations. A cylindrical taper is a piece of material that decreases in diameter in a cone shape. Proportions for tapers are often expressed as Taper per Foot (TPF), or Taper per Inch (TPI). Taper calculations most often expressed in terms of the difference in diameter at the opposite ends of the taper and the length of the taper ...

### Crusher Reduction Ratio

Jan 12, 2016 · Crusher Reduction Ratio I have mentioned the fact that, as the % of voids in the crushing chamber decreases, the production of fines by attrition increases. This is like saying that, as the Crusher Reduction Ratio in any given crusher is increased, the % of fines in the product will increase, even though the discharge setting remains unchanged.
