Delivery Points of Straight Handles

Direct shank is required to ensure that the entire axis is working properly, and the transcissile pulley is easy to slide out of the transmission shaft. When installing: pay attention to: 1, install with drill collet This mounting method is suitable for installing straight shank drills. Since it is inserted into the lathe tail sleeve with a tapered handle of the drill, after the drill bit is inserted into the three claws of the drill collet, it is installed with a key clamping, so it is generally only mounting the straight handle of φ13mm or less. drill. 2, install the drill package When the tapered handle number of the straight shank is consistent with the tapered hole number of the lathe tail, the tapered shank can be inserted into the lathe tail sleeve; however, if the number of the two is different, the drill set transition is available. For example, the drill tapered handle is 2, and the lathe tail sleeve cone is 4th, then it is necessary to use two drill sites outside 3 and inner 3, first put two drill sockets on the drill bit, then Then put it into the tail of the lathe. When the drill is removed from the drill sleeve, the dedicated slide is generally inserted from the waist hole of the drill sleeve. After a gently knocking of the oblique iron, the drill will be squeezed out. 3. Install with V-shaped groove iron This method is to mount the drill bit on the tool holder without using the lathe tail. As long as the two V-shaped grooves are applied to the drill bit (straight handle drill bit) on the tool holder, automatic feed can be applied. 4, install with special tools The straight shank can be inserted into the dedicated tool tapered hole 1, and the special tool 2 is partially clamped in the tool holder. After adjusting, you can use automatic feed to bore. Generally, the tapered hole of the special tool is generally formed, and if the drill bit does not match the drill bit and the tapered bore number; if it is a straight handle drill bit, the drill tip is applied to the tapered hole of the special tool. Inside, install it with a drill collet.

Non-standard Knives Are Customized, First Need To Pay Attention

In the process of machining, some difficulties in which it is difficult to use standard tools, and therefore, the production of non-standard cutters is important to mechanical cutting. Because metal cutting uses non-standard cutters more common in milling, the production of non-standard cutters in milling processing is slightly introduced. Since the fabrication of standard tools is for the cutting of a wide range of common metal parts or non-metal parts, it is very easy to stick to the hardness of the workpiece, or the workpiece is stainless steel, etc., and some workpiece surface geometry The shape is very complicated, or the surface has a high roughness requirement, etc., the standard tool cannot meet the needs of processing. Titanium machinery is a main product of rotation, screw, axial machining, CNC lathe processing, knife holder rod, and chuck pick-up, so during processing, the geometry of the tool, the geometry of the knife, geometry Angle, etc., for targeted design, can be divided into two major classes that do not need to be specifically customized and needed. It is mainly to solve two problems, such as dimensional problems and surface roughness problems. If it is a size problem, you can choose a standard tool similar to the size of the desired size, can be solved by reforming, but also pay attention to two points: () The size is not too large, generally do not exceed 2mm, because the dimension is too large, causing a change in the groove shape of the tool to directly affect the cost of costumes and geometries. (2) If it is a vertical mill with a blade, it can be changed on a normal machine, the cost is low. If it is a keyway milling cutter without a blade, it cannot be carried out on ordinary machines, and it is necessary to be in a special five-axis. The linkage of the linkage machine is higher. If it is a surface roughness problem, it can be realized by a change in the geometric angle of the blade portion. If the maximum number of the rear angle will significantly improve the surface roughness of the workpiece. However, if the machine is not enough, it may be sharply improved surface roughness, which is very complicated in this regard, and it is necessary to conclude after processing site analysis.

Summary With the Material of Alloy Drill

The main component of the alloy drill bit is tungsten carbide, cobalt, and the like. The alloy drill bit generally refers to a hard alloy drill bit, a score, welded, an invertable blade, and a replaceable head. The main ingredient of the cemented carbide is tungsten carbide, cobalt, etc., the hardness is high, which is generally higher than HRC90 degrees, and is more applicable in bulk processing and difficulty in hard work. The alloy drill bit in the market is generally the overall drill bit of tungsten steel, and the high-quality alloy drill bit will take coating treatment, such as aluminum nitride chromium (AlCrn) coating, the coating is a single layer coating, thickness 4 μm, Micro-hardness is 3200HV, the friction coefficient of 0.35, and the thermal stability is 00 degrees Celsius. After the coating, the drill bit is yellow on gray. After coating, alloy drills can process low alloy steel and high strength steel. High hard steel can reach 54 hrc.

How to Choose a CNC Tool

On the processed, all tools are all preserved in the knife library, and the corresponding tool change operation is performed by the selection knife of the CNC program and the tooling instruction. Use the corresponding standard shank for the machine tool system specification so that the CNC machining tool can be quickly and accurately mounted to the machine spindle or return to the knife library. The programmer should be able to understand the structure size, adjustment method, and adjustment range of the tool holder used to ensure the radial and axial dimensions of the tool when programming, and arrange the order of the tool reasonably. 1. Factors affecting CNC tool selection When choosing the type and specification of the tool, it mainly considers the following factors: (1) Production properties Here, the production property refers to the batch size of the parts, mainly considering the effects of tool selection. For example, in a large number of production, special tools may be costly, and when single or small batches are produced, choose a standard tool more suitable for some. (2) Machine Type The effect of CNC machine tools used in this process pair selected tool type (drill, car blade or milling cutter). Under the conditions that can ensure the rigidity of the workpiece system and the tool system, high productivity tools, such as high-speed cutting, and large feed pulses. (3) CNC machining plan Different CNC machining programs can use different types of tools. For example, the machining of the aperture can be drilled with a drill and a reagent, or a drill and a boring knife can be processed.
