With the continuous development of hole processing technology, the newly developed tool has a unique geometric structure, which can achieve higher metal removal characteristics under the premise of lower energy consumption. Using such tools can not only reduce costs, but also significantly increase production efficiency.
Sandvik Coromant: Promoting the Continuous Development of Deep Hole Processing
Suitable for four major areas of solution
Sandvik Coromant is not only good at processing parallel holes in the deep hole drilling process, but has been promoting the continuous development of deep hole processing, typical processes also include, for example, a highly complex inner circle profile processing. With the aerospace industry and the oil and gas industry, this type of demand is increasing. In addition, the major metals industry is seeking manufacturing solutions for parts such as heat exchanger plates, and the design of these parts has become increasingly complex.
Deep-hole machining is a "blind" process, which means that to achieve successful hole processing, you must have comprehensive capabilities such as knowledge, capabilities, and technical expertise. As a result, more and more customers are in need of cooperation with Cirencester Center, focusing on four major areas that form the core business of the Application Center, namely customer projects and technical support, product development, application development, and product and application training. These four areas provide customers with a complete solution "package."
Deep hole drilling with CoroDrill 800, drilling with deep hole jets and drilling, DHD tools can be customized for 5.5m deep,
Drilling of a generator shaft with a diameter of 100 mm.
Existing customers include high-quality, promising OEMs (original equipment manufacturers) from the oil and gas and aerospace industries. Some customers themselves have deep hole processing capabilities while others use subcontracting services. Companies using subcontracting services will also benefit from the processing solutions provided by Sandvik Coromant. In addition, some of the world's leading deep-hole processing subcontractors work directly with Sandvik Coromant to improve processing knowledge to better meet the market's needs and enhance their competitiveness. Among the newest customers, Perfect Bore Manufacturing, headquartered in Andove, is conducting feasibility studies on special alloys for the aerospace industry.
In terms of processing capacity, the application center is in the leading position in the industry. Craven deep-hole boring mills with complete reverse engineering have many high-standard features, including powerful countershafts and X-axis drives and robust shock absorbers, and high-voltage, High-flow coolant cools for efficient chip evacuation. In addition, real-time, high-definition video and data streams provide customers around the world with real-time online access to the latest performance test results.
Multi-task processing trends
One of the current technological development trends is multi-task processing. Sandvik Coromant is actively seeking cooperation with machine tool manufacturers to add deep-hole machining capabilities to the current traditional processing platform. It is now possible to provide a solution based on jet drilling, which can reduce the coolant flow/pressure by about 30% compared to single pipe drilling (STS), thus increasing the feed rate and allowing deeper hole processing . This applies especially to the processing characteristics of the latest engineering materials, most of which are not susceptible to chipping, such as modified martensitic stainless steels.
The services provided by Sandvik Coromant in this field of technology include process testing, performance testing and process optimization, in-depth knowledge of innovative new materials, as well as training and commissioning.
Wayne Mason, manager of the Sandvik Coromant Application Center, said: “There are only good products, but if they are not used properly, it is still futile. The application of knowledge plays a decisive role in the success of the project, which is precisely our business expansion. One of the main reasons."
At present, the oil and gas industry is quite active. Some parts, such as the rotary drilling system (RSS), can drill for 200 hours. The value of these parts is hundreds of thousands, so it can't be wrong. In addition, the aviation industry is currently developing rapidly. For example, the shell depth of the landing gear parts can reach 3 meters and the main engine axis can reach 5 meters.
"In the future, we will continue to work on the development of knowledge-based applications and new technologies and combine them," said Mr. Mason.
ISCAR: Significantly Improves Hole Processing Efficiency
High-precision machining and mass production of ultra-precision holes
The machining quality of the hole is affected by the depth of the hole, the workpiece holding rigidity, the quality of the coolant and the way of chip removal. As an upgraded product of the earlier successful product series Chamerrill and chameleon jet drills, SUMCACH continues the characteristics of quick-change tool heads. Both the head and the sipes are designed. It has been modified to have a high metal removal rate and high economy due to the replaceable cutter head.
Sumocham's revolutionary gripping mechanism increases the productivity and at the same time, the number of changeable heads is even greater. Drill pipe with spiral inner cooling through hole, more durable, more reliable structure. Provides four different standard geometry body replaceable heads for drilling steel, hard-to-machine materials, cast iron and aluminum alloys. The SUMOCHAM has a diameter range of 7-25.9 mm and drill depths of 1.5 xD, 3.5 xD, 8 xD and 12 xD.
Sumocham's unique sipe design uses cutting forces through mechanical structures. The cutting force is successfully converted into a clamping force and the blade is clamped with the reaction force of the sipe. It can be understood that the greater the cutting force, the greater the clamping force. The contact area produces less strain due to the clamping force and does not develop plastic deformation, which increases the number of interchangeable heads at least three times that of existing chameleon drill bits. The more important advantage is that the new clamping structure has increased the productivity by 50%. Lower clamping torque reduces internal stress in the sipe and increases tool life. The coupling part of the cutter head is of a cylindrical design, and the clamping area of ​​the coupling part is larger, and a thrusting part is designed to eliminate the possibility of the cutter head being pulled out and falling off.
Stainless steel wire cloth is available in a variety of weaves, including plain weave, twill weave, and Dutch weave. It is also available in different grades of stainless steel, such as 304, 316, and 316L, to suit different applications.
Some common uses of stainless steel wire cloth include filtration, screening, sieving, and separation in industries such as food and beverage, pharmaceuticals, chemical processing, and oil and gas. It is also used in architectural and decorative applications, such as for fencing, balustrades, and interior design elements.
Overall, stainless steel wire cloth is a versatile and reliable material that offers excellent performance and longevity in a wide range of applications.
In order to maintain long-term competitiveness, manufacturers are struggling to find a way to increase productivity and profitability without increasing costs. In addition, strong competitiveness and higher production efficiency help to shorten the delivery cycle of products while maintaining the existing positions and number of employees. To achieve these goals, tool makers are working hard to develop new cutting tools that are smaller, more efficient, vibration-free, and more fluent.
