In the simplest terms, 5-axis machining involves using a CNC to move a part or cutting tool along five different axes simultaneously. This enables the machining of very complex parts, which is why 5-axis is especially popular for aerospace applications. However, several factors have contributed to the wider adoption of 5-axis machining. These include: A push toward single-setup machining (sometimes referred to as [Done-in-One") to reduce lead time and increase efficiency
The ability to avoid collision with the tool holder by tilting the cutting tool or the table, which also allows better access to part geometry 5 Axis CNC Router Machine,CNC 5 Axis Router,5 Axis CNC Router,5 Axis CNC Machine JINAN XUANLIN MACHINERY CO., LTD. , https://www.cncfiberlaser.com
Improved tool life and cycle time as a result of tilting the tool/table to maintain optimum cutting position and constant chip load
Early electric separation is mainly used to separate the crude concentrate reselection, iron stone such as zirconium, rutile, monazite titanium and iron; cassiterite and tantalum, and niobium ore; cassiterite and scheelite. In recent years, gradually expand the range of applications, have been used for selection of hematite concentrate, production of iron concentrate, feldspar and quartz separation, sorting and phosphorus ore concentrate rough diamond, and has successfully achieved potassium electricity Selected industrial applications.
The selectivity of separation by minerals can be judged based on the electrical properties of the mineral, such as dielectric constant, electrical resistance, specific conductivity and rectification. In general, dielectric constant greater than 10 to 12 or more metal conductor; resistance is less than 106 ohms good conductor metal, conductive metal medium 10 is equal to 6 to 107 ohms, is greater than 107 Ohm show poor conductivity. Both the dielectric constant and the resistance can be used to determine the possibility of separation of minerals by electroporation. The specific conductivity is the relative value of the minimum voltage required for the mineral to deviate from the normal trajectory under the action of the high voltage electrode, and the sorting voltage can be roughly estimated. The rapid flow of minerals is used to determine whether the electrodes should be positive or negative. For example, a negatively charged mineral can only be obtained, which is called negative rectification. At this time, the electrode should be positively charged.
In the laboratory electric selection test, a drum type electric separator is generally used. The electric field used in the electric separator has three kinds of electrostatic field, corona electric field and composite electric field. The most widely used is the composite electric field electric separator. The electric separators are equipped with high-voltage devices that can change the voltage to 4 to 60,000 volts or higher. The effective sorting granularity is generally 1~0.075 mm. Before the selection, the sample must be classified according to the particle size. Generally, it must be preheated, and sometimes it is necessary to add a chemical for surface treatment. The following selection conditions should be determined during the study: particle size, grading ratio, sample heating temperature, surface chemical pretreatment method and conditions, cylinder rotation speed, potential difference, distance between electrodes, and productivity per meter length . Sometimes it is necessary to compare the type of electric field selected, the shape of the electrode, the material used to make the ore tank and the sorting cylinder.
In order to investigate the separation of the electrification, the ore bin below the sorting cylinder can be divided into a number of areas, in order to separately pick up products with different electrical properties, separately measure and test, and draw an optional curve according to this, determine the separation limit and select Other indicators.
