一． 用途
P-2A型金相试样抛光机（以下简称抛光机）适用于对经磨光后的金属材料进行抛光，可获得光亮如镜的金属表面，供在显微镜下观察与测定金相组织。
Model P-2A metallographic specimen polisher is applicable for olishing metallic materials after being ground and thereby metallic surface as bright as a mi rror can be obtained for the purpose of observing and determining metallographic stucture under a microscope.
二． 结构牲概述
抛光机由焊接工作台，工作台面，抛光盘，抛光织物，抛光罩及盖和开关等基本部件组成。工作台面上安装有两个抛光盘子，可供两人同时操作，使用十分方便。
两台电动机都置于工作台面下部，通过固定片与台面连接。固定抛光盘用的锥套通过螺钉与电动机轴相连。抛光织物通过套圈紧固在抛光盘上。电动机的起停可分别由安装在面板上的开关进行控制，电机起动后，便可用手对试样施加压力在转动的抛光盘上进行抛光。抛光过程中加入的抛光液可通过固定在台面上塑料盘中的排水管排出。抛光罩及盖可防止灰尘及其它杂物在机器不使用时落在抛光织物上而影响使用效果。
Tth polisher is composed of welded support worktable polishing disks.polishing cloths polishing covers and lids switch box and other basic components on the worktable are mounted two polishing disks whish are quite convenient for two persons to operate simultaneously.
Two motors are placed under the worktable and they are attached to the table by means of retaining pfates.The taper sleeve for fixing the polishing disks are joined to the motor shaft with screws and the polishing cloths are tightly wrapped on the disks by ferrules The start or stop of the motors can be controled by switches installed on the switch box .After a motor is started polishing can be done by using the hand to press the specimen against the revolving disk The polishing liquid added during polishing can be discharged through the drain pipe fit in the plastic tray on the table .When the machine is not in use. The polishing cover and lid can prevent the dust and other impurities from falling on the polishing cloth to impair the operation effect.
