PowerMILLIts the UKDelcam PlcThe company launched a three-dimensional complex shape CNC machining system。This article introduces its specific case in FAW mold manufacturing company，This paper introduces the utilization in detailPowerMILLSoftware secondary development environment，The development method of various common databases based on the actual situation of the company and the basic process of NC programming by using the database are established。 one、introduction Faw mold Manufacturing company mold numerical control processing technology application began20century80Early era，It has accumulated a wealth over the years
Self-aligning ball bearing[bearing:bearing（“Bearing”，Japanese person“Axial receptor”）It is a part that holds and reduces the friction coefficient of load during mechanical transmission。Can also be said，When other parts move relative to each other on the shaft，A device used to reduce the coefficient of friction during power transmission and to keep the center of the shaft fixed。]In addition to excellent quality，Its a very sophisticated part，If used improperly in the course of use，Not only can not achieve the expected performance effect，And its easy to makeFAGbearing[FAGbearing:The main shaft bearing is made of a solid inner ring、Outer ring、The ball、And with solid Windows
SKFImported bearing[Imported bearing:Simply put, the import bearing agent refers to the sale of an imported bearing brand。The main brands of imported bearings arenskbearing，ikobearing，fagbearing，Of good quality，Of course, the price is not cheap。]Precautions for use Compared with ordinary mechanical parts，The precision of rolling bearings is higher，Therefore, it should be used with care。 1) Keep bearings and their surroundings clean 2) Use it carefully If used carelessly to the bearing with strong impact，Will makeSKFImported bearing[Imported bearing:To put it simply
1CANBus introductionCAN(ControllerAreaNetwork)That is, the controller goes to the local area，A field bus mainly used for the detection and control of various devices。CANThe bus was originally made in GermanyBoschCompany for car testing、Designed for control systems。CANBus has a unique design idea、Good functional features and high reliability，Strong anti-jamming ability on site。Specifically speaking，CANThe bus has the following characteristics： *Simple structure，only2The root wire is connected to the outside，It also contains error detection and management modules。
usualIKOThe space in which bearings can be installed is limited。In most cases，Shaft diameter（OR-bearing[bearing:bearing（“Bearing”，Japanese person“Axial receptor”）It is a part that holds and reduces the friction coefficient of load during mechanical transmission。Can also be said，When other parts move relative to each other on the shaft，A device used to reduce the coefficient of friction during power transmission and to keep the center of the shaft fixed。]Inside diameter）Is based on mechanical design or other design limitations。thereforeI
Worm reducer is a compact structure,Large transmission,And under certain conditions with a self-locking function of the transmission machinery,It is one of the most commonly used reducer. The hollow shaft worm reducer is easy to install、Reasonable structure、Reliable and durable.Of course,Also pay attention to the choice of reducer brand,Powerful companies will be based on the shape of the reducer、The arrangement of heat dissipating ribs、Calculation of thermal balance、Oil circuit design and other design points,Combined with the actual use and operating conditions of the reducer,Adopt good manufacturing process,It is produced in high quality,Reliable and durable reducer.Users as long as the correct use of maintenance,You can get satisfactory results.
(1)Guiding accuracy Guiding accuracy refers to the accuracy of the moving path of the moving member when it moves along the guide surface of the linear guide rail。The main factors affecting the guiding accuracy are the geometric accuracy of guide guide surface、Structure type of guide rail、Contact accuracy of guide pair、Surface roughness、Stiffness of guide and support、Oil film thickness and oil film stiffness of guide pair，And the thermal deformation of guide rail and supporting parts。 The geometric accuracy of linear motion guides generally includes：Straightness in vertical and horizontal planes；Parallelism between the two guide rails。The geometric accuracy of the guide rail can be used by the error on the full length of the guide rail or the error on the unit length
Zhou Minghao Shi Xiaoping Jiangsu Provincial Health and epidemic Prevention Station one.introduction Because liquid chlorine disinfection of drinking water will produce carcinogenic mutagenic substances，Many countries in the world are trying to control the production of these harmful substances，Improve the chemical safety of drinking water，Chlorine dioxide was used（ClO2）As an alternative disinfectant to liquid chlorine。In our country８０Late introductionClO2Production technology，It has been used in serious water pollution and economically developed areas。Since there is no drinking water at presentClO2National standards and their supporting testing methods，This is to be fully promotedClO2Water disinfectant belt
a. Grease refill interval By mechanical action，Aging and increased pollution，bearing[bearing:bearing（“Bearing”，Japanese person“Axial receptor”）It is a part that holds and reduces the friction coefficient of load during mechanical transmission。Can also be said，When other parts move relative to each other on the shaft，A device used to reduce the coefficient of friction during power transmission and to keep the center of the shaft fixed。]The lubricating base filled in the configuration will gradually lose its lubricating properties。therefore，The lubrication rank needs to be continuously supplemented and updated。The lubricant refill interval will vary depending on the bearing[bearing:bearing（“Bea
Working principle: GPLSeries centrifugal spray dryer is gas-liquid two-phase parallel flow drying equipment，High speed centrifugal atomizer is adopted，Atomize the liquid into fine droplets，The hot air distributed with the distributor is mixed in the drying tower，Rapid heat and mass exchange，Dry to a powdery product in a very short time，Production control and product quality control are convenient and reliable，It is widely used in the drying production of different kinds of liquid materials。 Performance characteristics: For different kinds of solutions、Turbid liquid、Emulsion and paste materials can be continuously dried at one time。
