Demina MFG Solutions Bt-150h Precision Tool Grinding Equipment

Product Description

Diamond,PCD and PCBN Turning Inserts tool grinding machine

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 special turning and milling inserts, boring tools, grooving tools and many types of special turning tools.
I.  Features:

1. Mechanical Structure: The base of machine is made of solid casting with high quality. The main components weight is about 1.6 tons. It can meet grinding requirements of any hard material.
2. 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 .
3. The feed slider is driven by constant pressure air, ensuring high production efficiency and good finish on cutting edges.
4. Auxiliary work: pneumatic feeding device can realize fast forward and fast rewind of the grinding wheel, and can save 70% auxiliary operation time.
5. Wheel Oscillation: The grinding wheel oscillation is controlled by PLC program and move very smoothly. The swing range is between 0 to 30 mm (The max. swing range can be added to 150 mm according to the customer's requirement.).The grinding wheel is with uniform consumption and timely self-sharpening, to ensure the grinding precision and roughness.
6. Online CCD Measurement: using the optical microscope and CCD camera, the magnification is 25~80 times. The base line for comparison keeps unchanged after calibration. It ensures the measurement accuracy and makes the machine to measure the arc of tool nose accurately.
7. Declination Lock: The grinding spindle declines along the circular guide smoothly and radial lock can be made, greatly enhancing the rigidity of the equipment. After declination, the center line of the grinding wheel keeps the same height due to special mechanical design,so coarse and fine grinding can be made without declination adjustment.

II.   Technical Breakthrough

1. No vertical axis: vertical shaft lifting is not necessary because of height adjusting fixture on the workbench, greatly enhances the stability and rigid of the equipment.
2. Stable feed: in order to avoid periodic impact, the machine to be equipped with "flexible feed" of air pressure device, effectively improve the roughness of the tool edge.
3. Our company uses a big screen to display tool images in front of the operation position. An eye lift can cooperate. It improves production efficiency about 50%.
