BV-T1800 Vibrating Polishing Machine
Specifications
This type of polisher is suitable for the surface polishing of large quantity and batch of medium and large-sized parts.The polisher is mainly used for processing parts made of metals, non-ferrous metals and nonmetals, including removing burrs and rust, rounding and polish-processing, especially suitable for polishing long parts and the parts with complicated and irregular cavities. After processing, not only there is no damage to the original shape or precision of dimensions of the processed parts, but also the precision of the roughness of the processed parts can be raised 1 to 2 grades, in addition, the microhardness on the parts’ surface can be increased, and the internal stress can be removed, thus enhancing the fatigue strength. This type of polisher is suitable for the surface polishing of large quantity and batch of medium and large-sized parts

Main structure and working principle
The linear type of vibratory polisher BV-T1800 consists of a vibratory motor, a trough vessel (as seen in Fig.1), pedestal springs and basement. The vibratory motor is connected with the vessel by means of bolts and then together they are installed on the compression springs linked to the basement. The structure can be seen in Fig.1.
Being the main part that is vibrated in the course of polishing, the vessel should have greater rigidity, so it is made of steel plates welded together. In order to avoid scaring the parts’ surface and reduce noises the vessel is lined with rubber which is abrasion-resistant, acid and alkali- resisting, but not oil-resistant.
There are two groups of unbalanced loads on both the left and the right ends of the vibratory motor which is used to adjust the amplitude by changing the relative positions of the loads to meet the needs of polishing different kinds of parts.
When the motor’s spindle revolves at a high speed, the unbalanced loads will produce centrifugal force and tilting torque which, through the springs, cause the vessel vibrate regularly, and at the same time, the abrasive pieces and the parts in the vessel are also caused to vibrate regularly, thus the relative motion between the abrasive pieces and the parts polishes the parts.
The polishing process of the linear type vibratory polisher is a kind of vibratory grinding process in which the parts to be processed are put in the vessel where there are polishing abrasive pieces and grinding compound mixed by certain ratio. The regular vibration of the vessel causes a relative grinding movement between the abrasive pieces and the parts, thus removing the burrs from the parts, and at the same time rounding the sharp edges and polishing the surfaces of the parts.
Warranty period
The machine is warranted for a period of twelve months from the date of delivery. The warranty is dependent on the machine being checked and adjusted in accordance with the instructions given in the manual and being used under normal conditions.
