A twist drill is a tool that drills a round hole in a workpiece by rotating it relative to a fixed axis. It is named after the spiral shape of its chip groove, which resembles a twist. There are 2, 3 or more spiral grooves, but 2 grooves are the most common. The twist drill can be clamped to a manua Read More

As one of the most widely used tools in industrial manufacturing, it is very common to resharpen twist drill bits after they have been worn out. Most of the factories that use twist drill bits are resharpening them by hand in the grinding machine due to the constraints. The following is the manual g Read More

A spiral groove tap is a tool for machining threads. It is a type of tap, so named because of the spiral shape of its chip groove. Spiral groove taps are divided into left-hand spiral groove taps and right-hand spiral groove taps. The geometrical parameters of spiral groove taps are mainly reserved Read More

1, Fill some lubricating oil, use a sharp pin or chopper to slowly knock out the broken surface in the reverse direction, and reverse the iron sharpening from time to time (the most common method in the workshop, but it may not be suitable for threaded holes with too small apertures or broken taps that are too long, but you can try).

Q: What tools need resharpening?A: Most of the tools can be resharpened, in the production design to consider the subsequent tool resharpening; of course, on this basis tool resharpening should also take into account the overall cost and benefit; for most of the relatively low price, resharpening costs are relatively high tool can be directly scrapped and give up resharpening, because its own added value is not high.

Stainless steel is a common material in life nowadays, and it is loved by people because of its light weight and high hardness. Stainless steel is hard, difficult to destroy and difficult to transform, so the drill bit chosen is very important, so which drill bit is suitable for stainless steel? Read More

The premise is that we should first understand the processing characteristics of stainless steel. Stainless steel material plasticity, high toughness, but drilling stainless steel surface hardening degree, high cutting temperature, drilling twist drill is surrounded by stainless steel surface hole w Read More

The choice of milling cutter inserts:1, for fine milling, it is best to use ground inserts. Such inserts have better dimensional accuracy, so the cutting edge in the milling positioning accuracy is higher, can get better machining accuracy and surface roughness. In addition, the trend of milling cut Read More

A milling cutter is a rotating tool with one or more teeth used for milling. Each tooth intermittently cuts away the workpiece in turn. Milling cutters are mainly used for milling machines to process planes, steps, grooves, shaped surfaces and cut off workpieces. The author believes that in the sele Read More
