The S 250 G gear grinding machine from Samputensuli ("Samp"). It is considered to be a model of quality and reliability in the field of gear manufacturing.
The S 250 G continuous development and forming gear grinding machine from Samp, a well-known gear machine and tool manufacturer in Bologna, Italy, is the first fully functional gear grinding machine capable of performing various gear grinding cycles. This product is the result of Samp's active cooperation with the R&D and manufacturing departments of Italy and Germany. The S250G integrates the advantages and reliability of the Samp gear hobbing machine in operation and the flexibility and precision of the gear grinding machine to meet the customer's quality requirements.
This machine tool is the most efficient in the current market. This is advantageous for the selection of gear processing tools. Because it is more compact than most machines, the gears that need to be machined can be simulated under the control of the S 250 G machine. In addition, the S 250 G machine is not only fully equipped, but also adds the latest technology in gear production.
For gear grinding machines, the most important component is the grinding machine spindle, which moves along a small friction rail. The relative movement of the two is achieved by the ball screw spindle. The accuracy of the displacement of each axis is determined by the precision of the assembly of the components. The assembly of the components consists of a spindle, an absolute encoder and a tailstock. The motor power is 48 kW and the speed is 20,000 rpm. It can be equipped with a temperature sensor and a real-time position measurement system depending on the application. The synchronization of the tool and the workpiece is supervised by the Siemens CNC system and a magnetic encoder with thousands of resolutions. In addition, the spraying of the cooling oil is not only always arranged along the cutting point of the tool and the workpiece, but also by the diameter of the tool. The cut point position parameter varies with the wear of the tool.
The advantage of the new model of the S 250 G as a gear grinding machine lies in its own automated monitoring system. The machine is equipped with a modular loading and unloading robot arm. With the robot arm, the machine can be directly integrated into the production line. Since all the actions of machining the workpiece do not require other equipment, the user can immediately produce the product once it has the machine tool. This saves time and money.
In order to reduce the non-productive auxiliary time, the workpiece is automatically centered on another work table before entering the work area, and the workpiece is centered on the work spindle when grinding. That is, only a slight adjustment of the work spindle can greatly reduce the non-productive time of the workpiece. The robotic arm is designed for fast and safe requirements. When the machine is grinding, the loading and unloading manipulator automatically exits the work area. Once the workpiece is ground, it is clamped and the next workpiece is inserted into the workbench. In this way, the protective arm is protected from chips and oil during grinding and is more durable than other automatic loading and unloading systems.
The Samp company is characterized by continuous investment in research and development. For the technical and market grasp, SU's research and development is mainly reflected in the design of new machine tools, tools and speed of operation. The communication between various departments and customers enables the company to accurately grasp the specific requirements of customers and provide a full range of effective services. SAMP, Italy, invests heavily in R&D and process innovation every year. For example, in 2004 Samp invested 5.4 million euros in these two areas of innovation. In 2005, the company plans to invest a total of 9.1 million euros. In the three years from 2005 to 2007, it is planned to invest 8 percent of the annual turnover in research and development. The S 250 G is mainly used for high-volume gear production to meet customers' demands for quality, processing time and cycle tempo. When using a ceramic worm grinding wheel, the forming grinding and shaping can be achieved by electroplating a diamond-shaped standard wheel or a oscillating shaping unit with a conventional shaping roller. The modified standard wheel can completely rebuild the accuracy of the gear to ensure no error. In short, it is much easier to apply the trimming standard wheel to process. Modification is achieved by the standard development of the grinding process. No additional software, reprogramming or other processing is required before the machine is modified. While grinding the workpiece, the electroplated diamond trimming standard wheel is in the standby position of another workbench and can enter the work area in time according to the situation. The auxiliary shaping roller unit responds very well to bottlenecks in small batches, urgent orders and tool supply.
As for the tool, the Samp Group relies on Tyrolit GmbH partners. Thanks to Tyrolit's extensive experience in grinding and shaping, the good cooperation between the two companies provides customers with the support they need to use advanced technology.
Samp has established manufacturing facilities in Italy, Germany, the United States, France, Brazil, South Korea and China (a total of nine industrial bases at home and abroad). The company's total number of employees reached 560.
