Beijing Demina showcase products
Beijing Demina Precision Machinery co., ltd has shown three machines, BT-150H diamond tool grinder, BT-150N diamond tool grinder and APE40 drill grinder at the booth of 2D36.
BT-150H tool grinder uses the new pneumatic device of the grinder and the pneumatic device of "flexible feed". The design of this device can avoid periodic impact to a certain extent. And the tool grinding machine is equipped with a function to effectively improve the roughness of the tool edge. High grinding efficiency, improve the production performance of the grinding machine.
The BT-150N tool grinding machine uses new grinding software from the grinding machine industry. Our company's technical staff has developed and produced grinding software that can set various grinding parameters. The radial runout is 0.002mm and the axial runout is 0.003mm. Makes the grinding area of BT-150N tool grinder large. Moreover, the grinding efficiency of the equipment is improved.
APE40 drill grinder is a kind of sharpener, used for twisting, spot drilling, taps, step drills, countersinks, countersinks and reamer, and other grinding equipment. It has a wide range of use, so it is widely used by users use. When the device is grinding, the grinding head can rotate automatically, which saves manpower to a certain extent.
In response to the "made in China 2025" initiative, the integration of industrialization and information technology has entered a new stage. Beijing Demina is always innovating in grinding technology.
APE 60 universal drill tool grinder is widely used in industrial production. Before using the equipment, we generally debug it. It will be put into use after normal debugging. Today, Demina will introduce the debugging operation process of the universal drill tool grinder.
Commissioning operation process of APE 60 - Sharpening Machine
1. During operation, the grinding wheel and the slide table are adjusted to a certain small angle so that the front edge of the grinding wheel contacts the blade to ensure the quality of the blade.
2. The amount of knife can be adjusted by shaking the handwheel to move the slide base back and forth.
3. The angle of the sharpening knife can be adjusted by turning the adjusting wire and adjusting the sliding table.
4. The amount of extension of the knife can be adjusted with a top wire top knife.
After using the sharpener to adjust the above several parameters, use a compression wire to fix the blade to be sharpened on the blade holder through the pressure plate. And then push the blade holder to the left and right to carry out the grinding operation.
Reasons affecting the sharpness of the sharpening machine
The sharpness of the is very important. It can effectively improve the efficiency of sharpening.
The installation and adjustment of the sharpener will affect the sharpness of the sharpener. When installing, pay special attention to the stability of the device. A stable device can ensure that the firmware is firmly connected to prevent device vibration.
Secondly, the composition of the equipment abrasive will also affect the sharpness of the precision APE 60 – sharpening machine. If the abrasive contains too much corundum, it will easily wear the blade. If the amount of diamond is too small, the blade is not easy to sharpen, it needs to ground for a long time, and it is easy to deform. In addition, the operation method of the sharpener has a great influence on the sharpness of the sharpener, so it is necessary to master the correct operation method.
BT560 series tool inspectors are usually used in tool factories, tool grinding centers, and tool procurement inspection departments. They can efficiently and accurately inspect the geometric elements and their accuracy of various types of tools. These elements are usually important factors related to the cutting performance of tools, and their accuracy standards are generally accepted by the automotive industry.
The functions of BT560E Tool Tester
The mechanical structure of BT-560 tool tester is simple. The tool angle is adjusted by a rotating axis. The high-resolution CCD camera is fixed on two straight axes to adjust the observation position. The geometric shape of the tool is measured by image analysis software, because these geometric shapes may affect the overall cutting performance of the tool. This is the focus of the tool tester.
BT560 tool tester can be divided into pixel measurement and grating measurement from measuring principle. Pixel measurement is based on the display pixels of an image (an instantaneous image) as the basis of measurement and calculation, so in the case of different magnification, the "occupied" pixels per unit length (e.g. 0.002mm) are different, so it is necessary to calibrate for different magnification ( that is determining the number of pixels per unit length). This method is flexible and convenient to operate, but it can only be measured in a single field of view with a small measurement range. Its measurement accuracy is affected by the display resolution and calibration accuracy. It is suitable for occasions where the measurement accuracy is not high.
Grating measurement is based on the position of camera coordinates (X and Z-Axis) and the angle of the tool rotation axis (B axis). One of the methods is to overlap the vertical straight line segment (or horizontal line segment) of the cross line with the edge of the cutter's contour. At this time, the corresponding grating reading is cleared to zero, and the handwheel is rotated to move the corresponding linear axis so that the straight line segment coincides with the other edge of the cutter's contour. At this time, the value displayed by the grating is the linear size. Another method is to take the center point of the cross line as the "mouse pointer" and collect the key points on the cutter image for drawing, so as to achieve the purpose of measurement.
Note that the display window moves the tool image instead of the cross cursor, and the calculation is based not on the pixel but on the raster coordinate display value. The measurement method has high accuracy, because it does not need calibration, and the measurement results have nothing to do with display resolution. In addition, the grating measurement range is large, not limited by a single field of view, but can be observed by the motion of the guide rail. The geometric line segments and arcs are drawn by this method will "stick" to the image with the movement of the image, which is suitable for measuring large cutters whose images are beyond the field of view.
