BT-150B super hard (PCD & PCBN) tool grinder

The BT-150B super-hard tool grinding machine produced by Beijing Demingna Precision Machinery Co., Ltd. can economically manufacture and repair PCD, PCBN and CVD tools, carbide and high-speed steel non-standard blades. When grinding standard or non-standard welding tools, machine clamps, boring tools, slot cutters and other types of tools, it is easy to grind the transition edges such as angles and arcs on these tools.
Machine features:
(1) Mechanical structure: The machine bed (base) adopts an integral casting with a weight of 0.96 tons, which can meet the requirements of grinding of any super-hard material.
(2) Electric spindle: The grinding head adopts high-precision variable frequency speed control electric spindle, the power is 3.0 kW, the maximum speed can reach 4000 rpm, and it is cooled by circulating water. The rotation precision of the grinding head spindle is 0.0015mm, the jump is 0.0025mm. .
(3) Servo feed mechanism: using electronic handwheel + control servo structure, grinding feed and fast forward and rewind in manual and program control mode, ensuring operation safety, improving grinding efficiency and improving blade Mouth grinding quality.
(4) Grinding head reciprocating swing mechanism: the swing frequency is 0-60 beats/min, and the swing amplitude is adjusted freely between 0-50mm, so that the grinding wheel is evenly consumed, and the self-sharpness is timely, ensuring the grinding precision and roughness.
(5) On-line CCD measurement: using optical microscope zoom and CCD camera zoom technology, the magnification is up to 100 times, and the scribe line as the comparison reference is not enlarged, which ensures the accuracy of the comparison, so that the machine can accurately detect From the R05-R6's various tool nose arcs, it is also possible to accurately measure the grooving knife width and the angle of the tool tip for real online monitoring and measurement.
(6) Computer display and teaching: The CCD image and each raster coordinate are displayed in real time using a computer display. Captures images of the momentary state of the grinding state, as well as recording footage of the grinding state for remote presentation and guidance via the Internet.
(7) Angle encoder: After detecting the tool, the tool grinding position can be accurately restored to avoid the disadvantage that the tool is not ground repeatedly and the angle resolution of the digital encoder is 1′.
(8) Radial locking of grinding wheel shaft: radial locking technology of grinding wheel spindle makes the two arc guide rails hold the bumps tightly and tightly, achieving smooth contact without gaps, greatly enhancing the rigidity of the equipment and grinding the cutting edge of the tool. Quality has improved by one level.
Technical breakthrough point:
(1) Double-station design: It can be easily operated and observed in two working positions of the machine tool. The working position (the grinding wheel axial direction) can avoid splashing water, and the side working position is convenient for cutting special tools such as cutting knife and partial knife. Grinding.
(2) Optimization of vertical axis: The vertical axis with very little adjustment is integrated on the fixture of the workbench, which greatly enhances the stability and rigidity of the equipment.
(3) The end of pneumatic feed: the instability of pneumatic feed, puts high demands on the operator's "feel", which is the fundamental reason for the low efficiency of grinding and the difficulty of qualified operators. Instead of using the micro-motion servo, it is not only freed from the sharp point of the "Swiss precision", but also perfectly guarantees the grinding quality of the cutting edge.
(4) Automatic search and measurement: CCD imaging is processed by computer software, concentric circle marking is generated by computer software, and high-tech means support “free mechanical adjustment”, “automatic seeking”, “automatic edge finding”, “ Many functions such as automatic measurement, "coordinate display", "image acquisition", "video recording" and "online teaching" improve the work efficiency by more than 30%.
