The BT‑150H super‑hard tool grinder is an economical machine for manufacturing and resharpening PCD, PCBN and CVD cutting tools. It can also produce and resharpen non‑standard inserts made of cemented carbide and high‑speed steel. Equipped with pneumatic feed, the machine realizes “flexible feed” and ”constant‑pressure grinding” to improve grinding efficiency. Its unique wheel inclination design enhances machine rigidity.

Machine Features

1. Mechanical Structure: The machine base is made of high‑quality one‑piece casting. Major components weigh up to one ton, satisfying grinding requirements for all superhard materials.

2. Motor Spindle: High‑precision variable‑frequency motor spindle with circulating water cooling. Spindle rotation accuracy: end runout 0.002 mm, radial runout 0.003 mm.

3. Pneumatic Feed Mechanism: Adopts constant‑pressure grinding technology. A constant air pressure acts on the cutting tool during grinding, ensuring stable and consistent grinding process and high overall grinding efficiency.

4. Auxiliary Motion: Pneumatic feed enables fast forward approach to the grinding wheel and fast retraction back to clamping position, cutting auxiliary time by up to 70 %.

5. Reciprocating Servo Oscillation of Grinding Head: Servomotor‑driven wheel reciprocating stroke adjustable from 0 mm to 30 mm. It achieves even wheel wear and self‑sharpening, guaranteeing grinding accuracy and surface roughness.

6. Online CCD Measurement: Variable‑magnification optical microscope plus CCD camera with magnification 1X‑4X. Software‑generated reference reticles are calibrated and fixed as benchmark to ensure measuring precision. The machine can accurately measure tool nose radius. Angle‑line and graphic import functions support measurement for non‑standard cutting tools.

7. Radial Locking for Wheel Spindle: The concave‑convex circular guideways are tightly locked for gap‑free smooth contact, greatly improving machine rigidity. Adjustment of wheel elevation angle (which determines tool clearance angle) does not shift the wheel centerline; hence no wheel‑height adjustment is needed between rough and finish grinding.

Technical Breakthroughs

1. Optimized Vertical Axis: Fine‑adjustment vertical lifting axis is integrated into work‑table fixture, significantly improving machine stability and rigidity. (8S000G is optional)

2. More Stable Feed: PCD is hard‑brittle material vulnerable to impact (especially cyclic impact). The improved “flexible feed” with air pressure provides yielding function when cutting‑edge suffers impact, effectively improving edge surface roughness.

3. Large‑screen Image Display: A large display screen is placed directly in front of the operator station. Operators can view images with simple eye movement without frequent head turning or lifting, raising production efficiency by approx. 50 %.
