  • Introduction Of Tap

    Basic Introduction To TapTap is a thread processing tool, for our grinding is usually divided into straight – slot tap and spiral – slot tap. Tap belongs to the hole processing tool, generally there is a bottom hole, and then the hole wall processing thread. It can also be divided into machine tap and manual tap. Taps are divided according to their shape into straight – slotted taps, spiral – slotted taps and spiral – pointed taps (apex taps). Straight – slot tap is easy to process, slightly lower precision, larger output. It is generally used for thread machining of general lathe, drilling machine and tapping machine. Spiral groove taps are usually mainly used for blind hole drilling in CNC machining centers, with fast processing speed. It has the characteristics of high precision, good chip removal and good performance.The front part of the screw tip tap has a chip tank, which is used for the processing of the through hole. The unequal diameter design of tap cutting distribution is reasonable, and the processing quality is high. However, it still has certain disadvantages, that is, the manufacturing cost of the tap is also high.  Trapezoidal thread taps are often designed with unequal diameters. Tap is the most popular tool used by manufacturing operators in tapping.Grinding Tap Repair Equipment And GrindingThe equipment we use is usually manual equipment APE40. Tap we repair relatively less, repair the grinding of the front end guide part. Usually the original wear guide with a line cut off, after the equipment to do a new guide. With milling cutter, there are two kinds of grinding methods, one is to repair the groove, the second is to repair the surface of the knife. For the tap, the straight flute tap, the effect is relatively good after the grinding, the spiral flute tap, after the repair of many customers reflect that the grinding is not very good.

  • PCBN Insert Cutting Parameters

    Parameters Of The PCBN Insert Cutting1. Conventional cutting parametersWhen PCBN insert cutting is roughing, we should ensure the highest possible metal cutting speed and the necessary tool durability, so we usually choose the highest possible cutting depth. Then select a larger feed amount, and finally determine the appropriate cutting speed according to the durability requirements of the tool. When we use PCBN insert cutting for finishing, in order to ensure the grinding accuracy of the equipment, we should ensure the machining accuracy and surface quality requirements of the workpiece. Therefore, generally choose a smaller feed and cutting depth, and choose a higher cutting speed as much as possible. Therefore, when performing PCBN insert cutting processing, we must choose the appropriate cutting workpiece according to our actual situation.2.

  • Drills Is The Most Widely Used Hole Processing Tool

    Drills are the most widely used hole processing tool The drill bit is widely used in mechanical processing hardware, it is used to drill through-hole or blind hole on solid material, and can be on the existing hole reaming tool. However, different types of drill bits are selected in different operating environments. Common drill bits mainly include twist drill, spot drill, center drill, and deep hole drill. Although reaming drill and counterboring drill can not be drilled on solid material, they are usually classified as a drill bit. A twist drill is the most widely used hole processing tool. The diameter usually ranges from 0.25 to 80 mm. It mainly consists of the working part and the handle. The working part has two spiral-shaped grooves, shaped like twists, hence the name. The top Angle of the cutting part of the standard twist drill is 118, the bevel angle of the transverse edge is 40° ~ 60°. And the back Angle is 8° ~ 20°. The shank of the twist drill has two forms: straight shank and taper shank. The former is clamped in the drill chuck while the latter is inserted in the taper hole of the spindle or tail of the machine tool. General twist drill with high - speed steel manufacturing. Use of Drills A deep hole drill is usually a tool for machining holes whose ratio of hole depth to the aperture is greater than 6. Commonly used are gun drill, BTA deep hole drill, jet drill, DF deep hole drill and so on. The reaming drill has 3 ~ 4 cutter teeth, its rigidity is better than the twist drill. It is used to enlarge the existing hole and improve the machining accuracy and finish. The countersunk drill has more cutter teeth, and the hole end is processed into the desired shape by forming a method. Which is used for machining countersunk head hole of various countersunk head screws or the outer end face of the countersunk hole. The center drill is used for drilling the center hole of the shaft workpiece, which is essentially composed of twist drill with small spiral Angle and spot drill, so it is also called a compound center drill.
  • Common Problems With PCBN Blades

    PCBN tool is an artificial cubic boron nitride tool, which can still maintain high hardness characteristics at high temperatures. In the current grinding work, PCBN tools are mainly used for machining iron parts. PCBN tools have high hardness, chemical inertia, and thermal stability at high temperatures, so PCBN abrasive wheels are widely used in grinding processes. Although PCBN tools are widely used now, we still need to pay attention to some problems in the process of using them.Common Problems With PCBN Blades1. Is cutting fluid added when the PCBN blade processes the workpiece?Generally do not add cutting fluid, especially the integral PCBN blade, if you must add cutting fluid under the circumstances can contact the tool engineer to communicate to choose the appropriate cutting fluid.2. Are PCBN blades expensive? How much is one tablet?PCBN blade price is certainly higher than the carbide tool, different specifications of the price are different, the specific price needs to call the tool company to consult.3. How many workpieces can be processed by one cutting edge of the PCBN blade?PCBN blade does not have a clear life value, due to the size of the workpiece to be processed, precision, finish, etc. Its life is different, specific needs to communicate with the company’s tool engineers, so as to obtain a general range.4. Can the PCBN blade be resharpened?It can be reground, but the ordinary grinding wheel cannot be ground, so we need to buy a diamond grinding wheel for grinding.
