With the increase in the number of high-precision and high-hardness mechanical parts, as well as the development of precision casting and precision forging processes, the performance, variety and output of grinders are constantly improving and growing. (1) Cylindrical grinder: It is a common b...... [Read More]

One, choose according to the tool material 1. Tool steel knives: It has poor heat resistance and requires good cooling effect. It is better to choose emulsion. 2. High-speed steel tools: The highest temperature can reach 600°C. When cutting at low and medium speeds, use oil-based cutting fluid...... [Read More]

The advantages of cutting fluid are mild and non-toxic, controllable concentration ratio, easy operation, and only warm water or alkaline cleaning agent can remove the residual liquid. In addition, the cutting fluid also has the function of preventing chip buildup and rust prevention. If the c...... [Read More]

Cutting heat, sawing vibration and wear are the three primary factors leading to premature damage and failure of band saw blade. All three will shorten the service life of the band saw blade, resulting in unnecessary cost waste, and users have to spend more on purchasing new saw blades. Avoidi...... [Read More]

Cutting fluids can be divided into oil-based cutting fluids and water-based cutting fluids. The lubricating effect of oil-based cutting fluid is good, while the cooling effect of water-based cutting fluid is more outstanding. Water based cutting fluid is generally composed of emulsion, semi sy...... [Read More]

1) Install the saw blade correctly: loosen the locking screw, tighten the saw blade clockwise (only with your hands, not with the lever), and tighten the saw blade (the saw blade is pulled too loosely, or it may fall off), and then tighten the two M10 The sawing machine can only be started aft......

The internal leakage of the oil pump of the metal band saw is caused by the internal leakage: the volumetric efficiency of the worn internal leakage of the gear pump decreases, and the output power of the oil pump is much lower than the input power. All its losses are converted into heat energ...... [Read More]
