Machine-Tools; Sharpening (tool or cutter grinding) Machines, Numerically Controlled

BT-150D 4-Axis CNC PCD&PCBN tool grinder is made of grinding wheel oscillation axis (X axis), grinding wheel inclination (C axis), workpiece horizontal plane rotation axis (B axis) and workpiece feed axis (Y axis). The workpiece feed axis (Y axis) is equipped with a raster ruler for closed-loop position feedback to ensure micron-level grinding. This tool grinder is suitable for the production of medium and large quantities of carbide inserts, PCD inserts and CBN inserts. Once the centering is finished, grinding will be done automatically, realizing constant pressure grinding and flexible feeding. Due to the high hardness of the diamond material (PCD) and the rapid wear of the grinding wheel, the system can automatically detect this wear and compensate for it, and can maintain the dimensional accuracy of the grinding for a long time.

1. Mechanical structure: The machine base is made of an integral casting weighing 1.5 t, which can meet the requirements of grinding any hard materials require. The machine is equipped with a grinding fluid shield to ensure that the grinding fluid will not splash around. The optical component and CCD camera are properly protected from splash by metal cover. This certifies that water does not enter the lens during operation and that its optical adjustments are not inadvertently altered. There are lights inside the machine tool.

1. Electric spindle: The grinding head adopts a high-precision frequency conversion speed-adjustable electric spindle, power: 5.0KW, and the maximum speed is 8000 r/min. The inner of spindle is cooled by recycling water. The radial run-out 0.002 mm and axial run-out is 0.003 mm.
2. Guide rail: The use of high-precision needle roller guide rails significantly improves the rigidity, accuracy and durability of the machine.

4. Servo mechanism: The control servo structure. The two linear feed axes (X and Y axes) and two rotating axes (C and B axes) are controlled by servo motors, which can be driven by the application program to perform four-axis linkage. Improve the grinding efficiency and improve the edge grinding quality.
5. Grinding head reciprocating swing mechanism: The grinding head swings under the drive of the servo motor. The oscillation frequency is 0-60 times/min and oscillate adjusted between 0 and 120 mm. The grinding wheel is with uniform consumption and timely self sharpening, ensure the grinding precision and roughness. The grinding wheel oscillation is controlled by CNC program and move very smoothly with speed optimization. Oscillation length, position and frequency can be set in the program;
6. Grinding wheel shaft radial locking: The radial locking technology of the grinding wheel spindle makes the two arc guide rails clamped and locked, achieving a gapless and stable contact, greatly enhancing the rigidity of the machine and improving the grinding quality of the tool edge by a level.
7. Lubrication system: Intermittent automatic lubrication system. Users can set time and intermittent for oil, ensure the service life of the screw.
