What are the points to consider when choosing an Carbide drill bits? Below, the editor will explain them to you.1. Before selecting Titanium alloy drill bit, we should first understand the variety and characteristics of drill bits. The drill bits used for printed boards include straight beam Fried Dough Twists drill bits and fixed beam Fried Dough Twists drill bits. At present, most of the CNC deep hole drilling machines used by manufacturers use cemented carbide fixed beam drill bits, which can...

5% cobalt-containing taps with strong wear resistance and cutting performanceAfter the cutting edge comes into contact with the grinding wheel, it should be ground from the main cutting edge to the back, that is, starting from the cutting edge of the drill bit, and then slowly grinding down along the entire back cutting surface. When the 5% cobalt taps drill bit is cut in, it can gently contact the grinding wheel, perform a small amount of grinding first, and pay attention to the uniformity of s...

The angle of attack of the drill bit edge does not match the material of the workpiece, which cannot be solved for Precision machine taps. The drilling debris during drilling is constantly related to the properties of the material being drilled. Generally, softer and more viscous materials will not break on their own during drilling, and the drill bit needs to be frequently lifted out to clean the debris during drilling to prevent excessive entanglement of the drill bit with debris and affect ch...

It is easy to cause a series of problems such as poor roughness of the machined threaded hole, T603 sheathed tap chip sticking, severe wear and fracture, which seriously affect the service life. To improve and effectively solve the above problems, it is particularly important to extend the service life of squeeze Armored tap.Due to the fact that cutting machine tap produces internal threads by removing the workpiece material, the flat top and bottom tooth profile will not increase the tapping to...

Proper operation of twist drill bit is very important, not only for ensuring personal safety, but also for extending the service life of Cobalt containing Fried Dough Twists bit. Below, the editor will introduce what needs to be done when using T401JIS Advanced Metric Coarse Thread Series:1. Before use, check if all components of the drilling machine are functioning properly;2. The drill bit and workpiece should be clamped and tightened, and the workpiece should not be held by hand to avoid inju...

How to grind it well? The T401JIS screw tip metric coarse thread coating needs to be leveled with the grinding blade and the grinding wheel. The grinding wheel and the tool to be ground should be placed on the same horizontal plane, and the person with a high mouth should be in contact with the grinding wheel. In this way, the entire cutting edge should be ground. While the grinding wheel rotates, it should slowly follow the net surface closely. The grinding wheel surface should maintain a 60 de...

When drilling thin plates for T201 JIS Hand Tap Metric Coarse Thread Series, the workpiece should be reinforced. When drilling large workpieces, please ensure the stability of the workpiece. When drilling steel parts, please ensure sufficient cooling and use metal cutting fluid. Good drill rod rigidity and guide rail clearance can improve the accuracy of drilling and the life of the drill bit. Please ensure the flatness and cleanliness between the magnetic seat and the workpiece. At the beginnin...

1. For chip removal and coolant, machining workshops often use the method of injecting coolant from the outside to assist in chip removal. However, this method is only suitable for situations where the machining hole depth is smaller than the hole diameter and the cutting parameters are reduced. In addition, it is necessary to choose the appropriate type, flow rate, and pressure of coolant.2. Processing cost: After the drill bit wears out, users do not need to replace the entire drill bit body,...

The definition of drilling production and processing has also undergone a change. In fact, by using T301JIS screw metric fine thread coating appropriately, drilling productivity can be greatly improved and production costs per hole can be reduced. Coated threaded steel have the characteristics of high toughness, fast cutting speed, and wear resistance, and are suitable for producing parts of various materials. According to the refrigeration structure, T301JIS screw metric fine thread coating can...
