一种超薄金刚石砂轮生产方法
技术领域
本发明涉及磨具技术领域，具体属于一种超薄金刚石砂轮生产方法。
背景技术
以金刚石为代表的金刚石磨削工具发展迅速，应用已经渗透到机械加工、汽车制造、航空航天、生物、医疗器具、电子信息、建筑、交通、地质采矿等领域。目前，绝大部分人工合成的金刚石都为粉末状或细小的颗粒状，为了利用金刚石进行高精度，高效率磨削加工，通常采用结合剂将金刚石磨粒粘结起来并制成具有一定强度和形状的模具，以便于安装在各种磨床上进行磨削加工。与其他磨料如刚玉、碳化硅相比，用金刚石模具进行磨削时，其具有磨削效率高、使用寿命长、磨削力小，磨削温度低、磨削精度高等优点。但现有的以金属材料耐磨性较低，实用寿命不够长。
发明内容
本发明的目的是提供了一种超薄金刚石砂轮生产方法，克服了现有技术的不足，利用备料，混料，热压成型，冷却四个步骤生产出一种超薄金刚石砂轮，该砂轮具有刚性高，耐热性好，耐腐蚀性好，型面保持好，润湿性好，磨削温度低等优点，而且增大了砂轮的硬度和强度，减少刚性磨削形成的裂纹，其磨削效率和使用寿命远远超过传统砂轮，该生产方法具有，流程简单，易操作，社会效益明显等特点。
为解决上述问题，本发明所采取的技术方案如下：
一种超薄金刚石砂轮生产方法，包括以下步骤：
步骤一，备料：按配方称取金刚石65份、氧化铝25份、铁粉8份、碳酸锂3.5份、氧化钐2.5份、滑石粉3份、铬刚玉磨料18份、聚酰胺蜡微粉2.8份、偏苯三酸三辛酯1.6份、膨润土3.2份、白云石4份、黑锰矿石4.5份、石英砂 3.5份备用；
步骤二，混料：将步骤一中除铬刚玉磨料和金刚石以外的其他所有原料在混料机上混料均匀，然后再加入铬刚玉磨料和金刚石混料均匀后备用；
步骤三，热压成型: 将步骤二所得混料倒入模具中，再将模具放入压力机压制，同时加热模具，先预加压1-2兆帕，压力机上下压板板加热到200-400℃，时间1-2分钟，然后持续加压到10兆帕，保压4-8分钟，然后将压板温度升至600-900℃，保压1-3小时，最后压板温度持续升温至1200-1500℃，保压4-5小时；
步骤四：冷却：将步骤三热压后的模具，从压力机中取出，放置在冷却室内，待冷却砂轮完全冷却后，取出砂轮即可。
进一步，所述的金刚石和铬刚玉的粒度均为100-160目。
