BT-150H is designed for the economical manufacturing and regrinding of cutting tools made from PCD, PCBN, CVD, tungsten, carbide and other materials. It can grind angles and radii on standard and nonstandard turning and milling inserts, boring tools, grooving tools and many types of special turning tools.

I.  Features:

• Mechanical Structure: The base of machine is made of solid casting with high quality. It can meet grinding requirements of any hard material.
• Grinding Spindle: With high precision and variable frequency, the direct-drive spindle power is 3 Kw, max speed is 4000 r/min. The inner of spindle is cooled by recycling water. The axial run-out is 0.002 mm and radial run-out is 0.003 mm .
• Pneumatic feed: the machine adopts the "constant pressure grinding" technology. The feed slider is driven by constant pressure air, making the grinding process balance and stability, ensuring high production efficiency and good finish on cutting edges.
• Feeding work: the cutter approaches the grinding wheel and the cutter returns to the clamping position after finishing grinding, the two movements can realize fast forward and fast rewind of the cutter through the pneumatic feeding device, which can save auxiliary time up to 70%. The working feed is controlled by the servo motor through the electronic hand wheel, and the grinding efficiency is high.
• Reciprocal pendulum mechanism of grinding head: using PLC control for the grinding head swing, stable and no vibration, the size can be easily controlled and the swing is adjusted freely between 0 to 30 mm, making the grinding wheel uniform consumption and timely self sharpening, ensuring the grinding precision and roughness.
• Online CCD measurement: the use of zoom optical microscope and the CCD camera magnification technology. The magnification is optional between 25 ~ 80 times at will.
• Grinding wheel spindle radial locking technology: the technology makes the              two arc guide rail hold tight in concave and convex, with the spring of the elastic compression, adjusting angle automatically in the control panel through the motor. The utility model has the advantages of no clearance and smooth contact, and greatly improves the rigidity of the equipment. The adjustment of the grinding wheel elevation (relief angle of the tool) does not change the position of the center line of the grinding wheel. Therefore, coarse grinding and fine grinding need not to adjust the height of the grinding wheel.

II. Technical Breakthrough

• Optimization of the vertical axis: the vertical shaft lifting of micro-adjustment integrated in clamping device of worktable, can greatly enhance the stability and the rigidity of equipment
• Stable feed: PCD is crisp and hard material. In order to avoid periodic impact, the machine is equipped with “flexible feed” of air pressure device. It has function of cutter back-off when the cutting edge of the tool is impacted by the force, which improves the roughness of the tool edge effectively.
• The use of large screen: displaying of the data of all coordinates and the tool image, located in front of the operating station, do not have to turn around and look up, as long as lifting eye, the operator can be coordinated to provide production, improving efficiency of about 50%.
• Grinding wheel main shaft angle is online-controlled by servo motor. The primary and secondary relief angle can be reground at one clamping and avoid the manual-operated error due to the online automatic adjustment .
• Grinding wheel integration: only once clamping, finish and coarse grinding can be done on one grinding wheel. It makes the regrinding more efficient and more accurate.
