Chainsaws are useful tools for cutting workpieces. The sawing machine is the first machine that determines the process further. The sewing machines to be discussed in this report are hacksaw machines and hacksawing machines. Hacksaw is used for simple jobs in low production quantities. For jobs with high accuracy requirements with high capacity, special saw machines are needed that work automatically with the help of a machine. Meanwhile, you may also want to check out the electric chainsaw ratings, so you can choose the right one the next time you want to buy it.
Working principle of hacksaw (hacksaw)
Hacksaw is used to cut workpieces such as metal bars, steel profiles, other metal sheets that are too thick to cut. Where hacksaw is driven by human power (without engine).
Hacksaw Machine Components
Hacksaw has parts, namely:
a. Handle lever (Handle); It is usually made of soft metal and must have good grip (like holding a gun).
b. Adjustable frame (Adjustable Frame); Usually made of oval/steel pipes that are strong and stiff so that the results are straight and strong. This frame can be used for various lengths of the saw blade.
c. Wing Nut; Serves to tighten the saw blade.
d. Hook hole in the saw blade (Prongs);
e. Saw blade (Blade); Can be made from carbon or HSS with only the eyes (teeth) hardened or all parts. The smaller the angle of removing the saw blade, the harder the material can be cut. Size of the saw blade (in length):
– 8 inches (203.2 mm)
– 10 inches (254 mm)
– 12 inches (304.8 mm)
Saw blade making material:
– High speed
– Tungsten steel alloy
The dimensions of the saw blade, in general, the saw blades have dimensions:
– Width: ½ inch (12.7 mm)
– Thickness: 0.25 inches (0.635 mm)
– The distance between the teeth on the saw blade is called a pitch and is only in inches.
– Pitch = 1/8 states that in 1 inch (25.4 mm) there are 18 teeth.
– Generally pitch on the saw blade: 4, 18, 24, and 32 teeth/inch
