Introduction and classification of commonly used tools in cnc

Classification of the cutting tool It is divided into turning tool, hole processing tool, milling cutter, broach, thread tool, gear tool, automatic line and CNC machine tool and reamer and other types. The tool can also be classified according to other ways, such as the material used is divided into high speed steel tool, carbide tool, ceramic tool, cubic boron nitride (CBN) tool and diamond tool; According to the structure, it can be divided into integral cutting tool, insert cutting tool, machine clip cutting tool and compound cutting tool. According to whether the standardization is divided into standard Cutting Tools and non-standard Cutting Tools, although the classification is many, but the correct choice of Cutting Tools, in order to play Properties of Cutting Tools. Introduction to commonly used cutting tools 1. Turning tool Turning tool is one of the most widely used tools in metal cutting without signature machining. It can be used on the lathe to process the outer circle, end plane, thread, inner hole, also can be used for cutting and cutting, etc. In structure, turning tool can be divided into integral turning tool, welded assembly turning tool and mechanical clamping blade turning tool. The turning tool of mechanical clamping blade can be divided into machine tool turning tool and indexable turning tool. The cutting performance of mechanical clamping tool is stable, and the workers do not need to sharpen the tool, so it is used more and more in modern production. 2. Hole machining tool

The Value of CNC Machine Tool Chucks

Chucks Value for CNC Machine ToolsChuck is a mechanical system used on machine tools such as lathe machines to clamp workpieces. A machine instrument accessory that utilizes the uniformly distributed radial movement of the movable claws on the chuck body to clamp and position the workpiece. A chuck body, mobile jaw, and jaw drive mechanism are normally composed of Chuck. The chuck body's minimum diameter is 65mm, and the mean diameter is 1500mm. To move through the workpiece or bar, there is a through-hole in the middle. On the back, there is a cylindrical or short conical structure which is attached directly or through the flange to the end of the machine tool spindle. Chuck is normally mounted on the lathe, the cylindrical grinder and the internal grinder and may also be used for CNC milling machines and drilling machines with different indexing devices. Chuck has become an important tool in order to make the processing of machine tools more accurate and stable. There are lots of types of lathe chucks., six jaw chucks, and special chucks on the basis of the chuck claw number. The manual chuck, pneumatic chuck, hydraulic chuck, electric chuck, and mechanical chuck can be separated on the basis of the use of electricity. The hollow chuck and the strong chuck can be split depending on the structure. In fact, there is a wide gap between imported chuck and heat treatment and detailed process treatment, the key problem of chuck production. Moreover, there is a huge number of consumers in the domestic market and fierce competition, so that producers have to regulate the quality of the goods as much as possible and trade the attractiveness of the market for a lower price. This leads to some common problems with domestic chucks, such as poor stability, short service life, retention time of short repeat accuracy, and so on. Due to its strict procedure, most of the imported chuck ensures repeated clamping precision and long service life for the stable chuck. Lubrication is especially necessary in order to guarantee the good accuracy of the lathe chuck after long-term usage. Incorrect or inadequate lubrication can result in abnormal operation, weakening of clamping force, poor precision of clamping, abnormal wear, and low pressure seizure, so the chuck must be properly lubricated. First, at least once a day, add molybdenum disulfide grease (the color is black) and push the grease into the chuck nozzle until the grease spills over the claw surface or the inner hole of the chuck (the inner hole protection sleeve and the connecting nut). However, if high or large amounts of water-based cutting oil are rotated by the chuck in the processing process, further lubrication is required, which must be calculated according to different conditions. Secondly, the chuck body and slide surface must be washed at the end of the operation with an air gun or similar equipment. Then, to keep the sliding surface of the claw clean and lubricated, the chuck should be disassembled and cleaned at least every 6 months in order to increase the chuck's service life. In addition, to stop the internal rust of the chuck and reduce the clamping force due to the rust of the chuck, cutting oil with an anti-rust effect is used so that the workpiece can not be clamped. Equipped with a suitable chuck to make CNC machine tools more efficient, manufacturers need to choose to play a better role depending on the actual situation of their goods.

Difference between metal lathes and wood lathes

Lathe machines are used for CNC turning and many other operations. Wood lathe machines and metal lathe machines are common styles. All sorts of cutting equipment used in woodworking machinery machines, from log cutting to wood products processing. It is mostly used in manufacturing departments for construction, home tools, and wood mold. Woodworking machine tools can be divided into woodworking sawing machine, woodworking planer, woodworking lathe, woodworking milling machine, woodworking drilling machine, tenoning machine, tenoning machine, woodworking sanding machine, and auxiliary woodworking tool trimming and sharpening machines according to manufacturing methods and artifacts. Woodworking machine tools are normally made up of six primary components. -Device for cutting. Used at high speed to make the tool rotate. -System feeding. It is used to feed rollers, conveyor chains, and sports cars with wood or cutting equipment. -Device guide and keep down. It is used to direct the wood, such as a guide plate, compactor, etc, to the cutter or to press the wood. -Guards for protection. It is used during cutting to avoid wood recovery, such as a fan-shaped plate, delivery stop, protective cover, etc. -Collection system for dust. It is used during processing to collect sawdust and dust that is produced.

Machine for Face Milling

A type of CNC milling process is face milling. The face milling machine has a wide processing range that is ideal for the face cutting of metal materials such as castings and steel parts, and is commonly used in the manufacturing of machinery. It is particularly suitable for the mold industry and the plastic mold framework for plane milling. It can be used on both ends of ultra-long workpieces for milling, grinding, boring and other special surface machining. The face milling machine will mill the workpiece plane, chamfering the trapezoid surface and T-groove, drilling can reach φ 50mm, boring can reach φ 400mm. The two ends of the super long workpiece can be milled, manually drilled, bored and machined with a special surface after mounting the support slide. The milling force, which can meet the machining requirements of the components, is high. The column lifting adopts a counterweight unloading device, making it easy to travel up and down, not only extending the lead screw's life, but also making the cutting secure. For milling, the bevel gear drive is adopted with high precision and low noise. After mounting a frequency converter, Stepless Speed Shift can be introduced. The entire machine is rigid, not easy to harm, simple to manage, multiple functions, broad geometric dimensions, and is an ideal machining equipment. There are several types of end milling machines, usually differentiated according to the scope of the layout and application. 1. Table lifting milling machine: universal, horizontal and vertical, most generally used for the manufacturing of small and medium-sized components. 2. Gantry milling machine: including a gantry boring milling machine, a double column milling machine and a gantry milling planer used to process large parts. 3. Single column milling machine and single-arm milling machine: The horizontal milling head of the former can travel along the guide rail of the column, and the worktable can feed longitudinally; the vertical milling head of the latter can move horizontally along the guide rail of the cantilever, and the height can also be balanced along the guide rail of the column. Both are used for large parts manufacturing. 4. Workable non-lifting milling machine: there are two types of function tables, i.e. the worktable angle and the worktable circular. Between the lifting table milling machine and the gantry milling machine is a medium-sized milling machine. The vertical movement is finished with the raising of the milling head on the column.
