With the maturity of SLA light-curing 3D printing technology, some smart tablet manufacturers have begun to use 3D printers to include in their enterprise plans. The 3D printing tablet Model is completely proofed according to the original shape of the plan, with low error. Compared with the traditional prototype, it saves the cost of proofing, shortens the manufacturing cycle of the prototype model, ensures the confidentiality of the product development planning scheme, and greatly improves the work efficiency and product development. According to the feedback from the manufacturer using the SLA 3D printing prototype of Harbin Industry, the business volume has increased rapidly and the labor cost has been saved by 40% since the use of the D printer prototype for about a year since March. Let’s see how 3D can help hand board manufacturers save 40% of labor costs!

3D printing technology is widely used because of its flexibility and convenience. Printing technology involves different molding processes and material classification.

The rotary transformer of CNC machine tool factory is a common angular displacement measuring Device on CNC machine tools. It has the characteristics of simple structure, sensitive action, reliable T operation, low requirements for environmental conditions, large amplitude of input H signal and strong anti-interference ability. Signal processing is more complicated, and resolvers are widely used in semi-closed-loop controlled CNC machine tools. According to the functional relationship between output voltage and rotor angle, resolvers can be divided into the following j basic types: ① sine and cosine resolver. The excitation of single-phase AC Power Supply is applied externally on the primary side, and the two output voltages of =ik r are related to the sine and cosine functions of the rotor angle respectively. ② Linear resolver. In a certain working angle range gate, the output voltage and the angle of rotation are linear functions. ③ Proportional resolver. It is similar to the sine and cosine resolver, with the addition of a device for adjusting and locking the rotor position in structure. In the system as a proportional component to adjust the voltage. The structure of the rotary transformer in the CNC machine tool factory The rotary transformer of the CNC machine tool factory consists of two parts, the stator and the rotor, as shown in Figure 4-16. Two distributed windings whose axes are perpendicular to each other in space, that is, two-pole two-phase windings, are embedded in the fixed and rotated iron core slots, respectively. CNC Machine Tool Factory S, S. and S: S. They are identical in structure for the purpose of setting the windings. R, wind and R, R are rotor windings, and their structures are exactly the same. The stator winding is the primary side of the transformer, the rotor is the secondary side of the transformer, the excitation voltage is connected to the primary side, and the frequency is usually /iOOHz, oOOHz, 1000Hz and 5000Hz. The mutual inductance between the stator and rotor windings of the CNC machine tool factory changes according to the sine and cosine laws of the rotor deflection angle. One signal changes in proportion to the sine of the rotor angle, and the other signal changes in proportion to the cosine of the rotor angle. The stator winding lead wire Directly to the terminal block, while the rotor windings are connected to the terminal block through slip rings and brushes. The two-pole resolver commonly used in CNC machine tool factories has a pair of magnetic poles for the stator and rotor. In addition to this, there is a multi-pole resolver.

1 Introduction

Chemical heat treatment is to place a metal or alloy workpiece in an active medium at a certain temperature for heat preservation, so that one or several elements penetrate into its surface to change its chemical composition, structure and properties. Compared with surface quenching, chemical treatment not only changes the structure of the surface layer, but also changes the chemical composition of the surface layer. After chemical heat treatment in CNC machine tool factory, combined with conventional heat treatment, the surface and core of the same workpiece can obtain different microstructure properties. The CNC machine tool factory can be divided into carburizing, nitriding, carbonitriding, boronizing and dissolving chromium, etc. according to the different elements infiltrated. 1) Port carbon of CNC machine tool factory steel Carburizing is a chemical heat treatment process in which steel workpieces are heated and maintained in a carburizing medium to infiltrate carbon atoms into the surface layer. The main purpose of the carbon is to improve the surface strength, wear resistance and fatigue strength of the workpiece, while maintaining the good toughness of the core. Carburizing steels are generally low-carbon non-alloy steels and low-carbon alloy steels, and the carbon content is oi%-o.2s%. The traditional carburizing methods include gas, liquid, and solid. Gas carburizing is commonly used in CNC machine tool factories. In order to improve the efficiency and quality of carburizing, new technologies such as vacuum carburizing and vacuum ion carburizing are gradually being promoted and applied. 2) Chlorination of steel in CNC machine tool factory Nitriding is a chemical treatment process in which nitrogen is infiltrated into the surface of the workpiece to obtain a high nitrogen hardened layer. The purpose of nitriding is to improve the surface hardness, fatigue strength, adhesion resistance and wear resistance of steel. The steel for nitriding is usually steel with alloying elements such as Al, Cr, Mo, Ti, V, etc., because these elements easily form various nitrides with fine particles, uniform distribution, high hardness and stability with ammonia. After nitriding, the workpiece will obtain high hardness, and no quenching treatment is required. In order to ensure the mechanical properties of the core, quenching and tempering treatment should be carried out before nitriding. Compared with carburizing, the workpiece after nitriding has high hardness, wear resistance and hot hardness without quenching. However, the chlorine time in the roadway is long, the cost is high, and the nitriding layer is thin and brittle, which cannot withstand the impact. It is mainly used for precision parts with high surface hardness, wear resistance, corrosion resistance and high temperature resistance, such as precision machine tool spindles, screw rods, etc. 3) Carbonitriding (cyanidation) of steel in CNC machine tool factory Carbonitriding is the process of carburizing and ammonia to the surface of steel at the same time, which is customarily called cyanidation. Cyanidation in CNC machine tool factory is to put the workpiece in an active medium containing cyanide or cyanide, and after heating and holding for a certain period of time, carbon and nitrogen will diffuse into the surface layer of the workpiece. Because cyanide is highly toxic, gas carbonitriding has been gradually used instead of cyanide. At present, there are many applications of medium temperature gas carbonitriding and low temperature gas carbonitriding. Medium temperature gas carbonitriding is mainly carburizing, and its purpose is to improve the hardness, wear resistance and fatigue strength of steel; low temperature gas carbonitriding Co-infiltration is mainly based on fluorine infiltration, and its purpose is to improve the wear resistance and adhesion resistance of steel.

Fault phenomenon: Once started, the external fuse of the driver is burned out, and the equipment cannot run. When the maintenance personnel inspected, they found that a power tube was damaged, but because there was no information, they could not figure out the function of the tube, thinking it was the front push of the power drive. , replaced a power tube, after the power was turned on, the insurance was burned again, and the replaced tube was also damaged.
