Now the energy industry has become a hot topic, and development has always attracted much attention. In addition to the traditional energy industry, emerging clean energy sources such as wind power, nuclear power, solar energy and tidal energy are increasingly valued by people. The rapid development of the energy industry has also put forward higher requirements for its related manufacturing industries. Among them, the tool is the tool is that the tool is the tool. One of the most critical factors is that under the premise of ensuring the quality and production efficiency of processing, we must care about how to choose a knife that should choose to choose for ourselves for the energy industry, especially the new energy industry.
Use interpretation and induction to obtain the most suitable product
The choice of tools is a very logical job. Each new project is like a reasoning question. You need to use interpretation and induction to get the most suitable products. In short, it is a process of continuous demolition and integration. The client's parts are very specific. You must demolish this thing as small as possible, detailed attributes, and each attribute has an impact on the design of the tool. To summarize these impacts Essence
For example, the processing of turbine blades, fan blades molds, a 5MW fan, its leaves can reach 60m long and 5m wide, the corresponding mold is also a big guy: from geometric perspective, large volume requires the quickly to remove the margin to remove the balance quickly. In Iska products, there are fast -metal cutting products such as the FEEDMILL series of tools under high -speed fees and interpolation and milling cutters. To remove the balance quickly, you must reduce the cutting resistance; when the long suspension is extended, it is easy to produce vibration. It is required that the cutting blade has strong impact resistance and good toughness; there is a space surface on the blades, and the knife is required to have arc elements. In summary, the following results can be obtained: Feedmill fast plane milling, cavity rough processing, Millshred for deep cavity and rough processing, and then use a round blades to process cavity.
Another example is the blade of the turbine turbine. The leaves used in the high temperature and high voltage of the steam turbine at the thermal power station are all high -temperature alloys. Toughness, so the cutting force is large, and the cutting temperature is high. The cutting resistance is reflected in the design of the tool, and the cutting force needs to be reduced by increasing the front corner and the rear corner of the tool; inhibiting the impact of the cutting temperature, the relevant results can be obtained through the knowledge of the knife coating. The thermal conductivity of the blade (tool) to slow down the impact of the temperature. Its role is like a layer of thermal film, because it has a thermal conductivity coefficient that is much lower than the tool substrate and workpiece material. For high -temperature alloys, Iska's SPS82C and IC380 are all PVD and nitrogen carbide coating for this difficult processing material.
There is a universal characteristic of the energy industry's parts. The material material is characterized by the processing of steel, stainless steel and high -temperature alloy. Iska has proposed the concept of FMR (FastMetalworkRemoval) at a very early days. And complete product lines can meet the processing of large workpieces.
Beginning in 2009, Iska has an upgrade of Helido for milling products. In short, it is the double -sided of the blade. The direct result is that the number of cutting blades can be 2 times on a blade. At the same time, the dough blade is located through the tunnel -tail blade, a larger cutting front corner, a small negative edge of the blade, we can well increase the life of the blade, and the Helido product will be a direction for the main promotion in the future. In addition to the improvement of coating, except for SPS82C and IC380, which are two special products for high -temperature alloys, all coatings have the corresponding SUMO (speed demon) technology upgrade. On the basis of ordinary PVD and CVD coating, plus a layer of alumina, the surface of the blade mouth is smoother, reducing the formation of dandruff tumors, and increasing the life of the tool.
From the beginning of research and development to actual sales, for conventional metal processing, in the comparison of the old products of Iska itself, the life expectancy increased by 10%to 30%. For non -metallic materials in the wind power industry, such as glass fiber, carbon fiber, and synthetic resin, Iska's poly crystal diamond knife (we call "PCDLINE") It has been proven to effectively prevent scales, damage, and crushing. These tools have common keywords: sharp blade, large front corners, front knife surface polishing, high -speed cutting, and small dandruff.
Shan Gao helps you stimulate infinite wind energy
In the process of the development of the new energy industry, Wind Energy, as a clean renewable energy source, is becoming more and more valued by countries around the world. European countries, the United States, and China have given strong support and promotion in their own energy planning.
In the process of the development of the new energy industry, Wind Energy, as a clean renewable energy source, is becoming more and more valued by countries around the world. European countries, the United States, and China have given strong support and promotion in their own energy planning. As a leader in the wind power industry, Shan Gao knife can not only provide high -quality tools and professional processing technologies, but also always focus on providing overall solutions for metal cutting demand. In the long -term cooperation with famous fan component manufacturers in various countries in the world, the mountain height has accumulated rich experience and strictly meets the almost "harsh" processing requirements of wind power parts manufacturers.
There are many factors such as fatigue, reliability, and vibration resistance from fatigue, reliability and vibration. For wind turbines, gear boxes, wind wheel hubs, wind power bearing (rotary support and gear), fan shafts, and wind turbine seats are extremely important working components. At the same time, they are also parts with high processing difficulty, high accuracy requirements, and large processing volume. Shan Gao provides a series of process solutions for this to help users in the wind power industry stand out in the fierce market competition.
Wind power gear box is one of the important parts of the wind power unit. Because the operating conditions of the wind turbine are complicated, reliability, and the requirements of service life, the gear box must have sufficient rigidity, suitable support structure and wall thickness to meet complex stressive needs. Common materials include ball and ink cast iron and other high -intensity cast iron. The mechanical structure of the gear box is complex and huge, which requires hundreds of hours of precision processing. Parts are more processing.
The types of machine processing of wind power gear box include milling (corn mills and three -sided blades), drilling (Perfomax series), and ravioli (bridge board 镗 风). It is worth mentioning that the diameter of the gear box connection holes exceeds 2m, and its tolerance requirements are H7. This processing is quite difficult. The mountain height Graflex bridge -type bull -headed standard products cover the size of 204 ~ 2155mm in diameter; giant (JUMBO) bridge plate hoe, the maximum diameter can reach 3200mm. They are composed of high -strength aluminum alloy and steel parts interface, taking into account the needs of flexibility, knife weight and rigidity. The accuracy requirements of maximum IT5 and RA0.6 in the essence of the essence, the size adjustment is also very convenient, which can be completed directly on the machine tool. At the same time, the modular design can also meet the needs of large diameter rounds and backbone. For example, the A731001JUMBO bridge-panel-type knife is rough with TCMT16T308-F2TK2000 blade. The cutting line speed is 150m/min, the feed speed VF reaches 25mm/min, and the depth AP is 5 ~ 6mm. The essence uses CCMT09T304-F2TK1000 blade, the cutting line speed is 120m/min, and the depth AP0.3mm is cut. These high -performance cutting parameters can ensure that customers have high component accuracy, but also greatly reduce the production cycle of customers.
The wheels are also one of the important parts of the wind turbine. Its structure and force deformation are complicated. It will directly affect the normal operation and service life of the wind turbine. Therefore, it has the characteristics of high strength, good reliability, long fatigue life, and strong vibration resistance to meet the use conditions of -20 ° C ~ 40 ° C. Common materials are low -temperature low temperature and high shock tough iron iron. The main machine processing types of the wheels are milling and drilling.
The wind wheel is huge, and the general processing cycle is long. A customer once encountered such a processing problem: Although all its machine tools were running at full load, production tasks could not be completed on time. In order to help customers cross the difficulty, Shanzhong designed a non-standard convertible formed tool with a diameter of 360mm and R85mm, supplemented by 335.19-1207en2R85-D09, F40M blade, and the cutting line speed is 200m/min. The quantity FZ0.14mm, cutting depth AP1 ~ 2mm, production efficiency is greatly improved, the production cycle of this wheel hub is shortened from the original 30H to within 16H. Customers were able to deliver smoothly to avoid major losses.
DoubleOCTOMILL double -sided blade R220.48 plane milling cutter is very suitable for wheel milling and processing. The blade of the double -sided blade milling cutter is designed with a positive front angle. Each blade has 16 cutting blades. The same milling cutter can meet the application occasions of coarse and precise processing, and has imperative economy and generalality.
The processing of wind power parts also includes a fan spindle, fan base, connecting flange, fan tower, planetary rack, fan blades, etc. For the processing of these parts, the mountain height has a solution for complete turning, milling and hole processing. Shan Gao's tools adhere to the concept of "becoming a strategic partner of customers" and are committed to improving the efficiency and competitiveness of processing for customers.
"High energy processing" becomes the focus
The eye -catching development of China's economy is continuing, and it is not exaggerated to describe it with supply. Railway networks and buildings are required to be inadequate. However, if a large number of mechanical equipment is introduced, the investment costs will be very large. Recently, customers have increasingly increased the requirements for "high energy production" and "high -efficiency production" on existing equipment.
Because the temperature of the generator's blades is very high during operation, the materials are mostly used for heat alloys. In addition, due to its complicated shapes, not only the tools, drills and vertical milling cutters, etc., are used during processing. Sumitomo Electric hard alloy is difficult to cut materials in the car blade. The material AC500 series is used. There are difficult to cut materials in the drill bit to process a multi -purpose drill MD. With inventory, the corresponding size is quite rich, which can fully meet the requirements of the complex processing of customers. The above -mentioned tools are all special materials developed for the difficulty of processing, so they can exert excellent performance in terms of wear resistance and laugher -resistant blade.
The eye -catching development of China's economy is continuing, and it is not exaggerated to describe it with supply. Railway networks and buildings are required to be inadequate. However, if a large number of mechanical equipment is introduced, the investment costs will be very large. Recently, customers have increasingly increased the requirements for "high energy production" and "high -efficiency production" on existing equipment. Therefore, the recommendation scheme of Sumitomo Electrician hard alloy is the following products with "high energy processing" as the following products.
Drivery processing: Ultra -high advances greater than f = 0.5mm/r are recommended to process dandruff processing excellent high -energy break -breaking groove series SE and GE types when processing is recommended. When the request is higher (~ 0.8mm/R), the light -edged blade type LUW type and Guw type are recommended.
Milling processing: It is recommended to use the MS1400 type of high -advancement and milling cutter. Although the depth cannot be greater than 1.5mm, the feed can be corresponding to 2mm/blade.
Drilling processing: The newly developed J -shaped horizontal blade repair improves dandruff treatment. Coupled with a special crumb groove shape, it can also exert excellent dandruff discharge when processing. In addition, because the latest PVD coatings and DEX coatings are used, it has achieved long life. Here is a hard alloy multi -purpose drill GS/HGS type. If the aperture is more than 12.5mm, it is recommended to use the sword head -replaceable drill bit SMD type.
High -hardness material processing
During the high -speed/high -energy rate processing of high -hardness materials, there are 4 coating CBN materials according to different uses. BNC100 is recommended during high -speed/continuous processing, BNC160 is recommended during weak interruption, BNC200 is recommended during high energy processing, and BNC300 is recommended during interrupted processing. In addition, the high -push is recommended during processing or high -precision processing.
The rotary supporting ring is a more representative difficult part in wind power components. According to the capacity (size) of the wind turbine, its size is also diverse, and the rotation support ring with a diameter of more than 2m is particularly difficult to process. In particular, the processing accuracy when processing (hard vehicle) after quenching (hard car) requires strict processing, the knife life is short, and there are many installation holes.
The first recommendation of the bearing surface after quenching (Hardturning) is excellent wear resistance and can correspond to the BNC160 that can be processed by large -scale workpieces. If there are high -speed processing requirements, it is recommended to use BNC100. The company prepares three types of blades for various CBN materials, which can choose the most suitable blade port according to the degree of damage of the tool and the required surface roughness.
Installed hole processing
The installation holes of the rotary support ring are generally about φ25mm, and the hole depth is about 100mm. When processing these holes, it is recommended to use the WDX type on the right. Each blade has 4 blade corners that can be used in good economy, and the most suitable blade broken dandruff groove is also good when processing L/D = 5 deep pores. However, if the accuracy requirements of the hole are less than ± 0.15mm, the aforementioned SMD type is recommended.
