Q:Why oil and gas chainsaw logging can be used for mixing

So most chainsaw select is two stroke engine as its power system. Compared with other types of engines, the two stroke engines have the advantages of light weight, large power, simple structure, strong and reliable, and durability. They are the first choice for the power of hand saw.

Q:Why do you want to repair concrete road pavement saws

It is not when sawing, pouring concrete pre isolated, concrete expansion is relatively large, easy to crack in the process of cold expansion on the road tile, you saw the so-called joint is actually the expansion joints, avoid high temperature in summer when the damage of asphalt pavement. In fact, you see what we can know, the asphalt will often muster a package in the innate, but not because of the asphalt pavement toughness was far better than that of cement concrete pavement

Q:Wo saw blade open black is still hot running backwards

So called "the tooth", breaking into a tiny kerf, for cross-sectional tenon pull shoulder, called "bite shoulder saw" leftists called "1 2 tooth" Baicheng saw the road

Q:Reciprocating working principle of pneumatic reciprocating saw and the working principle of high frequency quiver used for cutting sponge.

Pneumatic reciprocating devices are made by reciprocating movement of the piston in the cylinder. According to the requirements, the structure of various forms, and sometimes the same manufacturer, the same specifications, different models of products, there will be a big difference in structure. But the fundamentals are pretty much the same.

Q:Why is the carpenter's circular saw fitted with a shield?

Safe use of circular sawsAfter starting, the material can be sawn until the speed is normal. When feeding wood will not sway or high up, to meet a slowly feeding. The length of sawing shall be no less than 500mm. When approaching the end, push bar feeding is applied.The operator shall not stand in the direction of the centrifugal force in which the saw blade is rotated, and the hand shall not cross the saw blade.When the film temperature is too high, apply water cooling.

Q:The circular saw is very difficult and still smoking when cutting wood. What's the matter?

You change a saw blade, try it, maybe the saw blade is flat, and when you cut the thick wood, the friction is too big.

Q:Sawing parameters of band saw

Sawing pressure and feed rate: the sawing pressure and feed rate are determined by the type of material and the width of the material. Stiffer materials and larger widths require greater pressure and feed rates; softer materials and smaller widths require smaller pressures and feed rates.

Q:What kind of seam should be set on the concrete pavement? What's the function?

Set up the concrete pavement joint seam and contraction joints. After pouring concrete pavement shrinkage joint, strength has not reached the design strength (such as second days) saw the cutting machine, cutting depth must meet the concrete pavement thickness 1/3, if the temperature drops, due to thermal expansion and contraction of concrete plate along the kerf in addition to disconnect no, caused by irregular broken plate. Is an expansion joint in pouring concrete slab, with soft wood will be separated from the concrete plate adjacent (middle and dowel bars), it is the role of the heat expansion, the concrete slab has certain space, avoid the heat when the concrete slab concrete slab arch suspended, the pavement damage

Q:The use of cutting small pieces of jade saw blades

Saw blade is used to cut solid material slice, round tool collectively. The blade can be divided into: diamond saw blade for cutting stone; for saws cutting metal materials (not inlaid with hard alloy knife head); used for hard alloy saw wood, furniture, wood-based panel, Aluminum Alloy, aluminum, plastic, plastic steel radiator, cutting etc..

Q:Why do fitter saws T8, T10, T12 and other steel materials work harder than saw 10,20 steel, and the saw blades tend to be dull?

T8, T10 and T12 are carbon tool steels. They are very hard. The Brinell hardness in annealed state is more than 300.Manual saw blade is T12 material, just quenching, hardness is greater.10 and 20 are low carbon, high quality structural steel, very soft, Brinell hardness is less than 155.Therefore, the fitter saw, laborious, the saw is very easy to wear.
