Polishing Track is An Essential Factor of Polishing Effect

Precision polishing, namely polishing performance, is a common focus of polishing machine purchasers and suppliers. Polishing track is an essential factor that affects polishing performance.

Plane polishing machine polishing tracks include  fixed eccentric grinding trajectory, linear, uncertain eccentricity grinding grinding trajectory, squares, swing type grinding fractal grinding trajectory, planetary lapping tracks and so on based on different relative movement of machining and processing.

Eccentric grinding track workpiece material removal uniformity is poorer, the closer the center of the workpiece, the lower material removal rate is. Commonly used to small-size workpieces no greater than 200 mm in diameter high precision grinding and polishing machine.

Indefinite eccentric type grinding trajectory uniformity is much better than that of eccentric trajectory, which is beneficial to the improvement of the precision of workpiece surface shape. Suitable for machining of large size larger than 200 mm in diameter, production type mirror polishing machine for grinding and polishing track belongs to this type.

Straight line grinding does not employ polishing pad, but flexible abrasive belt. The workpiece simply does pure rotational motion. Plane grinding polishing machine self-finishing mechanism of cutting tool on the grinding disc trajectory is this. The simple movement forms, such as abrasive belt extension can form batch production and high production efficiency.

Planetary plane lapping movement is the most common used for double sided lapping machine. When the ratio of grinding disc speed and rotation speed of the sun change, the working efficiency and the material removal rate will change.
