三、外形结构原理（见附图一）
磨床的主要结构由砂轮调整、水平进给系统，模胎旋转及变速系统，电气控制系统三部分组成。
砂轮调整，主要完成砂轮切削，砂轮左右移动，胎具水平进退动作，以便进行各种规格的刹车片的磨限位边的加工。
胎具旋转系统包括模胎，变速机构，胎具电机等，主要带动刹车片完成旋转进给运动。

四、工作原理
磨限位边的砂轮电机（6）固定在纵向工作台拖板上，金刚石砂轮（5）与砂轮（6）电机直接联接，启动电机后通过砂轮的高速旋转完成对刹车片限位的磨削。刹车片由模胎（3）定位，模胎作低速旋转完成刹车片的磨削进给动作。通过纵横工作台丝杆螺母滑台（7，9）调节磨头（5）与模胎（3）的相对位置，完成不同规格的刹车片的端面及限位边的磨削加工。调整砂轮升降系统（7）用以调节不同宽度刹车片的磨削；调整水平进给系统（9）用以调节不同半径的刹车片的磨削；调整电机（10）经减速器带动模胎低速运转，从而完成刹车片磨限位边或端面的连续进给运动，更换不同直径的模胎，可实现不同半径、不同宽度刹车片的端面、限位边的磨削加工。

五、设备运输与安装
设备运输时必须防止倾斜、翻倒、撞击，避免剧烈震动，以防损坏砂轮系统及模胎系统。
设备需安装在平整的混凝土地基上，其水平应可调整。
设备安装就位调试好水平后，须用地脚螺栓与地基可靠地固定，以防止加工过程机器发生震动。
安装设备时，抽尘设备应同时安装到位。

六、设备调试
设备安装完毕，需对设备进行调试，砂轮升降系统（7）上下运动是否自如，水平进给系统（9）前进后退运动是否自如。
检查设备各部位是否处于正常状态，不得运转移动的部位是否有松动，设备各部位处于正常状态时可接通电源，通电调试。
检查各处确保砂轮固定可靠，模胎固定可靠，升降系统、水平进给系统等一切正常后，开启电机，使设备空运转，观察设备运转情况，若一切正常，即可进行试样磨削。
试样磨削：
安装好与试样内弧相符的模胎，将试样装夹在模胎（3）与专用夹紧装置之间，调整砂轮升降系统（7）到需要磨边的相应尺寸位置，一切准备妥当先启动砂轮电机，再启动模胎电机，手动操作砂轮升降、水平进给系统，进行试样磨削。
当试样磨削达到图纸尺寸（或约定尺寸后），将砂轮升降、水平进给系统锁定，即可进行同一种产品同样尺寸磨限位边、磨端面的加工。磨削中，加工到适当批量时应检查产品尺寸有无变化，若产品尺寸变化较大，应立即停车，检查原因，排除故障后方可继续磨削。

七、设备的维护与保养
每班上班开机前，应检查设备各部位是否完好，一切处于正常状态方能开机。
操作者必须能熟练掌握该设备的操作技能，并按安全操作规程进行操作。
每班下班前应清除导轨面及工作台面上的灰尘，调整升降、水平进给系统，清理干净，适量给丝杆加润滑油。
更换砂轮时应由专人负责，注意砂轮运转平衡，避免产生震动。
每半年应对轴承、减速器更换一次润滑油。

The machine is compact, simple adjustment, easy to operate, user may act according to different internal arc radius of brake pads,Exchanging different sizes positioned positioner, the various specifications of the brake disc surface and can be limited to grinding machining. Grinding drum size range: arc RADIUS within R150-300mm thickness 5-50 mm, 25-350 mm wide.Workpiece clamping: the bobbin rotates, the intrados of the brake pads have been grinding by positioning on the sheet posted on the bobbin, special clamping devices can be stuck brakes, limit and end of processing.Second, main technical parameterGrinding head motor: 5.5kW,2900rpm/minFeed motor: 0.75kw,125-1250rpm/min speedBobbin rotate speed: 3-30rpm/minDiamond grinding wheel size: around 180Dust collecting mouth diameter: around 100Productivity: 5000-6000 PCs/shiftOverall dimensions: length x width x height 1200x950x1200 (mm)Total weight: about 850kgNote: users can be customized according to the agreement, its parameter is subject to the agreement, the above parameters for reference purposes only. This equipment is in the process of updating, so if there are different, the actual device shall prevail, without prior notice.Third, form a structural principle (see photos)The main structure of the grinder wheel feed system with level adjustment, and bobbin rotate and transmission system, electric control system is composed of three parts.Wheel adjustment, main wheels cutting wheel to move around, and tooling level of advance and retreat, to carry out a variety of brake pad wear limit processing.Jigs rotating system including the bobbin, speed, positioner motor, main drive brakes complete rotation feed motion.Four, working principleLimiting side grinding wheel motor (6) fixed on the longitudinal carriage of table, diamond grinding wheels (5) and wheel (6) motor connected directly, start the motor through the high-speed rotation of the grinding wheel finish after grinding of brake pad limit.
