In the recent period, grinder manufacturers have also come up with something that is obvious to them; in order to continuously improve the function and processing accuracy of the grinding machine, just like the sensor monitors the process and the adjusted programming system and control module; general machine tool and active grinding machine Special components on the cutting system optimize the grinding process; linear motors are used for positioning speed and accuracy. In order to minimize the machining time of the parts; the grinding machine manufacturer also puts the policy on the combination of machining processes.
In order to keep up with the overall processing trend in mass production; Studer Schaudt in Stuttgart is equipped with a B-axis on the Zeus M-type cylindrical grinding machine. Dr. Ingolf Lammich, general manager of the company, said; "current; single The carriage grinder can only be equipped with up to 2 linear grinding shafts; compared to this type of grinding machine; the Zeus M2 new double-slide grinder can hold up to 4 grinding axes." Within the reversal range of 225°; can be converted to a point of view; The positioning accuracy is ±0. 001°. The motor is driven; when the reversal point of view is 180°; the time required for the motor to cut from the cutting to the cutting can reach 4s. When machining the journal; use the cutting and grinding; “This way; Grinding the shaft diameter of the width of the width.†Lammich said this when explaining the strengths of this approach.
Thanks to the robust progress of programming, another new product developed not long ago was the Kairos grinding machine for turning and grinding the deceleration shaft. In addition to the equipment, a cylindrical grinding unit and an internal grinding machine Outside the shaft; also equipped with an 8-station rotary grinding turret. "Because of a few shapes; firstly used for machining shaft and shaft turning; this is a very advantageous method"; Lammich thought. When machining the shaft and the shaft groove; there is a short main machining time and a sub-machining time. "But when machining the bearing housing; grinding is more suitable than turning"; Lammich added that the CBN die is used for multiple paths. When feeding to the feed; it is capable of extremely fast grinding of housings of different widths. At the time of processing the beat; the combination method can be used for machining or classifying three sets of grinding discs and B-axis on one machine. The sensitivity is very high when processing a few shaped workpieces.
Fritz Studer AG has developed a combined machine tool for the first time. The S 42 machine from the Swiss manufacturer of cylindrical grinding machines is not only capable of grinding but also turning; it also has the ability to machine shaft and bushing parts. Fine machining. There are two lateral carriages independently controlled on the tool holder; the longitudinal carriage selected with this carriage has strong rigidity; it can shorten the operation path. The left cross frame supports the grinding shaft seat; right Rotary tool turret with one 8 tool orientations on the side. Dynamically functioning front linear guide and linear measurement system; ensuring that the machine reaches extremely high precision. In-process measuring control and sensing for monitoring Skills; ensure consistent processing quality. Grinding software Studerwin and Studergrind can perform fast and robust programming; then reach useful use of the grinding machine.
Adding grinding speed together with the stability of the progress process "We have entered a new category with the S 12 cylindrical grinding machine"; Fred W, general manager of Studer. Gaegauf said in the analysis of the function of a new product. "Our linear share signal resolution on the X and Z axes is 10 nm; processing accuracy can reach 100 nm in the process of stability"; Gaegauf emphasizes that in order to arrive These top-level values; R&D engineers have come up with many good ideas. "In order to minimize the influence of the magnetic lines of the linear motor on the slide; each axis has two linear motors at the same point of view; and the length measurement system is equipped in the process. As close as possible"; Gaegauf explained that the built-in drive system, hydraulic system, spindle and electronic components cooling system ensure thermal stability. 1 set of measuring equipment, active piston proofing equipment, a set of tapered proofing system and a A device for grinding core electric tortuous compensation; ensuring that the bed reaches a higher machining accuracy. The high-function grinding software simplifies programming; together, it simplifies the operation of the grinding machine.
The R&D engineer of the CNC 435 combined grinding machine from the Buderus Schleiftechnik company in Asslar has put the combination of processing methods in the “extremeâ€. The company is carried out on state-sponsored projects. In addition to grinding and turning the shaft; It is also capable of hard roll cutting. In addition to combining these methods, it is also possible to combine other processes; for example, roughing turning; followed by grinding for extremely fine finishing. The grinding speed is selected to be 180 m/s. The machining allowance for grinding can also be reduced by large fluctuations; therefore, only the rough burrs for turning are required to be worn away. In addition, because the workpiece and the grinding tool are specially organized, they can also be processed synchronously.
The workpiece that is used for the rapid, accurate and reliable processing of the outer grinding machine; can be safely handed over to the east and west to make a new product developed by Ewag AG of Etziken, Switzerland; it can be used when grinding PKB and PKD tools. Speed; together ensure the safety of the process. Because in the processing of superhard materials such as PKB and PKD; the removal of the grinding wheel and the free orientation of the corrugated space are extremely important to the machining process; Ewag is equipped with the process for this Easygrind tool grinder Re-energizing inside. "This machine enables the abrasive tools and grinding wheels to touch the world forever; therefore, it is possible to use a progressive grinding strategy." Sales department manager Beat Oderbolz explains that, for example, it is often reproducible during roughing; a grinding wheel is always " Opened; and the amount of data at the unit time is relatively high. The grinding machine is equipped with a 3D measurement system, pressure-controlled grinding wheel feed and video camera system for equipment and measurement. "Compared with traditional processing; use us Easygrind grinding machine; grinding time can be shortened by about 30%"; Oderbolz ensures that.
The touch surface is more advanced and highly reliable. It is the research and development policy of Michael Deckel of Weilheim. Based on the S22 tool grinder, the engineers of Deckel have developed a belt with active Top and intermediate frame grinding machines; for active and efficient grinding of slender tools. The prototype was recently exhibited at the company's own trade fair. "At the EMO meeting; we will introduce the series of tool grinding machines"; Sir Bernd Woehr made sure that it was later; when it comes to processing difficult-to-cut materials such as titanium-aluminum alloys and nickel-based alloys, it is capable of high-speed machining. For high-power processing of such materials; Hamburg Blohm Maschinenbau The Profimat 607 surface grinder and the three-dimensional forming grinder are equipped with a linear rapid advancement workbench; the workbench can swing back and forth at a speed of 120m/min; the acceleration is up to 5g. Compared with the deep grinding; the rapid advancement of the rocking mill has a decisive advantage. Sales The head of the department, Ralf Bleich, stressed: "Because the touch surface is better than the Σ æ…湫æ¸è·£ æ…湫æ¸è·£ è€ è€ è€ è€ æ±‰ 汉 汉 汉 汉 汉 汉 汉 汉 汉 汉 ††††††††††††††The rate is high; the wear of the grinding wheel is less. The rapid advancement of reciprocating grinding is particularly suitable for processing materials that are difficult to grind and sensitive to heat; such materials are often used in the steam turbine and tool making industries as well as in machine building and medical skills. This type of grinding machine with 12 tool changers can also be used for milling and drilling.
According to Maegerle AG of Fehraltorf, Switzerland, the user chose the pocket-type deep-grinding middle of the company's own built-in rapid tool changer; the company has established a new image in the processing of special workpieces. This type of grinding machine is specially designed for small parts. The five-axis machining can be used to sensitively use a variety of abrasive tools; the first is to use a grinding wheel with a maximum diameter of 300mm and a width of 60mm. Consider the various process parameters of grinding, milling and drilling together; Press; two-axis water jets with a running speed of 20 m/min; the number of revolutions of the main drive shaft can vary up to 10000 r/min depending on the type of process.
