Experience has taught the correct number of teeth to use for different kinds and types of metal.
Below we illustrate the num- ber of teeth in Hand Blades and give the material each cuts satisfactorily. For cutting soft solid steel, iron, rails, brass, bronze, copper and alu- minum. For cutting tool steels, iron pipe, hard metals and light angle iron. This blade for general shop use. For cutting drill rod, medium sheet metal and tubing.
For cutting thin sheet metal and tubing. Hints on Cutting off Stock by Hand After selecting the proper blade, strain well in frame. The correct strain or tension is important to insure true cutting and to prevent breakage of blades. Be sure that blade is perpendicular and tight.
Material to be cut should be rigid and placed so as to engage the maximum number of teeth throughout the cut. This is especially true when cutting structural steel, channel or similar material.
Have Blade Cut Start the cut easily using the — not Rub same action as in filing. Be sure to put on sufficient pres- sure to make the teeth cut. If this is not done when starting the job, you will allow the saw to rub rather than cut and the teeth of the blade will soon glaze and become blunt.
After the first few strokes retighten the saw in the frame. Always Lift Saw on At the end of forward Return Stroke stroke lift the saw slight- ly, to avoid dragging or rubbing the teeth on the stock during the return stroke. Using pressure on the return stroke will wear off the cutting edge and reduce the efficiency of the saw.
Advantage of Slow Make 40 to 50 strokes per Steady Stroke minute your maximum speed and you will finish the job quicker than at 60 — 70 strokes, besides prolonging the life of the saw. If you desire fast cutting, operate the blade slowly and use sufficient pressure. Cutting Thin Stock Many Hack Saw troubles and Tubing come from trying to cut thin metal without the proper saw or proper precautions. For thin metal a saw blade should be selected with teeth fine enough so that two or more teeth will engage the work at once; for, if the spacing is so coarse [ 6 1 that the metal is allowed to catch between two teeth, the tendency will be to strip the teeth of the blade.
When sawing thin stock it should be well supported in the vise; if the work will permit, it should be held between two pieces of wood and the whole sawed together. The additional cutting that the blade must do in working down through the combination protects the teeth and prevents them from catching on the side of the metal, and, as a consequence, stripping the teeth. Whenever possible, sheet metal should be sawed with the blade at an angle to the work, thus presenting the greatest possible number of teeth to the work at one time.
Suggestions for Machine Use See that the saw is straight in frame and tight. Teeth should always point in direction the cut is to be made. Majority of machines are draw- cut and teeth should point away from the opera- tor. In push-cut machines the teeth should be reversed and point toward the operator. Have material firmly clamped in vise. Start a new blade with comparatively light pressure.
See that the blade is tightened sufficiently in the machine to give ample support in the cut. The most economical cutting Feed and Speed is done with slow speeds and comparatively heavy feeds. Only by experiment can the exact feed and speed, which will give best results with each type of blade and kind of material, be determined for the individual machine. It is evident that more pressure should be used when cutting heavy stock than for light stock.
Heavy With 60 90 Cooling As its principal action is one of Compound cooling, there is sufficient lubri- cating effect with even the cheap- est cutting compounds, provided the quantity used is great enough to produce the necessary cooling.
Deluge the blade and work, as high speed cutting generates heat which draws the temper of the blade. Always use cutting compound except when cutting iron castings and the output will be greatly increased. Number of Teeth In general the number of for General Use teeth shown below will be found to satisfactorily cut the material specified. Sketches illustrate the ex- act size of teeth of a given number per inch.
Used for cutting large sections of soft stock. Used for cutting medium sections of harder stock. Used for cutting small sections and very hard stock. For general use in medi- um machines. Some Suggestions Worth Remembering Power hack saw machines should be checked frequently to make sure they are in good condi- tion. Use a blade that is thick enough, wide enough, and with the correct number of teeth.
See that the blade is inserted in the machine so that the teeth point in the direction in which the cutting is done. After the first or second cut tighten the blade as it will stretch.
However, do not overstrain the blade. Start the blade with a light feed and as soon as it has cut through the skin of the stock, put on as heavy a feed as is recommended by the machine manufacturer. Use a cutting lubricant, except when cutting iron castings, for it will help clean out the chips from the kerf and save the teeth of the blade. If a blade wears out or breaks in a cut do not put a new blade in the same cut as it will prob- ably wedge or stick since the set on the old blade had worn down.
Some Causes of Blade Failure Most broken blades may be traced to one of the following causes. First, too heavy pressure applied in cutting a small surface. The blade gives at the point of the pressure, buckles and consequently breaks. Second, too weak strain on the blade.
When a slight over-pressure is exerted on a weakly strained blade the blade at once buckles and breaks. Third, cramping or binding.
If the sawing is not done evenly there is a side strain on the blade and the result is a broken hack saw blade. Under the cut- ting action, such work becomes loose, and the result is another broken blade. Pulled out ends on Hack Saw Blades is caused in most cases by grooved or worn pins see sketch A. Of course, the remedy for this is to renew pins. This same difficulty is also caused by the pin be- ing too small, so that the strain comes on one point rather than on half the circle of the hole see sketch B.
In such cases replace with a larger pin. All other power blades measure from center to center of holes. In Box Weight per Gross 12' x. All other power blades measure from center to center of boles. There are hundreds of shapes and sizes of files.
Only those in most general use are described and pictured in the following pages. There are two classifications by which files are generally known. These refer to the teeth and are known as Single-cut and Double-cut. A Single-cut File has single rows of parallel teeth extending the length of the file at an angle across its face. This is clearly shown in the illustration.
A Double-cut File has two parallel rows of teeth crossing each other. The first row is usually coarser and deeper than the second row. For this reason they cut faster but not so smoothly as the single-cut. Most of the files used by machinists are double-cut. Single and double-cut files in general use are further classified according to the distance be- tween the rows of teeth. Bastard, Second-Cut, and Smooth. The illustrations above show the variation in the cut of the teeth of a ten-inch Flat File double cut.
The illustrations on the next page show the difference in the cut of the teeth of an eight-inch Mill File single cut. The length of a file is the distance between the point and the heel. The tang is not included in the length. The heel is that end of the file that comes next to the handle. The point is the end of the file opposite the tang.
The tang is the pointed part that is in- serted into the file handle. SAFE means that the side, back, or edge, to whichever it refers, is smooth with no teeth. A file that has the same width and thickness from heel to point. This term is applied to a file having tapering sides, to distinguish it from the blunt file. All Simonds Files 10 inches in length and under are wrapped and packed one dozen in a box. All over 10 inches are packed one-half dozen in a box.
Exceptions: 9-inch and inch Flat and Hand, inch Half-Round and Cabinet Files are packed one-half dozen in a box.
A bandsaw also written band saw is a power saw with a long, sharp blade consisting of a continuous band of toothed metal stretched between two or more wheels to cut material. They are used principally in woodworking , metalworking , and lumbering , but may cut a variety of materials. Advantages include uniform cutting action as a result of an evenly distributed tooth load, and the ability to cut irregular or curved shapes like a jigsaw. Most bandsaws have two wheels rotating in the same plane, one of which is powered, although some may have three or four to distribute the load. The blade itself can come in a variety of sizes and tooth pitches teeth per inch, or TPI , which enables the machine to be highly versatile and able to cut a wide variety of materials including wood, metal and plastic.

Hacksaw For Metal
Having commenced manufacturing of abrasives at the very end of the 19th century, today Klingspor is a global manufacturer in this industry with 12 manufacturing locations, 2, employees and generating a turnover of more than million Euros. Recognised for its product lines of coated and bonded abrasives, until recently the Group was virtually absent in the diamond sector. Since May , the situation has evolved considerably with the introduction of the first diamond production line designed and manufactured by the German firm; for this opportunity Klingspor has invested in a high performance facility for its Ukrainian plant in Velyki Mosty, located 50 kilometres north of Lviv, near the Polish border. Committed to a strong industrial strategy, the Klingspor Group has manufacturing at the heart of its DNA and offers a product line consisting almost exclusively of items that it produces in-house. Thus, three years ago the decision was made to expand in the diamond cutting blade market, and since this date the firm has been looking towards a global market in which it should become one of the major players. To date, the first three steps have been taken, and the subsequent steps are already in the business plan to accompany the growth of the activity. The first phase of the Velyki Mosty plant was erected in to manufacture abrasive flap wheels.

Я, Хедрон-Шут, являюсь частью их сложного плана, Очень возможно -- весьма незначительной частью. Мне конечно, нравится думать, что это не так, но я не могу быть в этом уверен.
Как много людей знают о его существовании. - О, довольно много, но это их редко занимает. Время от времени сюда приходит Совет: пока все они здесь не соберутся, в город не могут быть внесены изменения.
Здесь не требовалось Хранилищ Памяти, чтобы оставить в неизменности все элементы этой первозданной планетки. Но если здесь не было воздуха, то, значит, не могло быть и жизни. Или же она все-таки могла существовать. -- Конечно, в этой идее с точки зрения биологии нет ничего абсурдного,-- сказал Хилвар, когда Олвин задал ему этот вопрос.
