金剛石滾輪使用方法及特點
The usage and features of diamond dressing roller
金剛石滾輪是一種高效的成型砂輪修整工具，特別使用於復雜型麵或高精度成型麵的砂輪修整，現在製作有電鑄法和燒結法兩種工藝而成。采用金剛石滾輪修整具有以下優點：
Diamond dressing roller is a high efficientdressing tool for molded grinding wheels, especially used for dressing complex surface or high precision molding surface of grinding wheel. There are electroplating and sintering producing methods to make the dressing roller. Diamond dressing roller tools have the following advantages:
n 生產效率高，使用壽命長，單件零件的修整成本低。
High production efficiency, long lifetime, low dressing cost for single component.
n 可長期保證零部件精度，粗糙度的穩定性,大幅降低次品率。
Can ensure the components’ precision and the stability of roughness in a long time, greatly lower the defective rate.
n 修整裝置構造簡單，交換頻率很低，減少操作人員負擔。
Simple structure of the dressing device with low switching frequencycan reduce the burden of operator.
廣泛用於汽車，機床，工具，輕工，軸承，航天等工業加工領域。
It’s widely used in various processing industries, such as machine tool, tools, light industry, bearing, aerospace, etc.

滾輪的修整方式
Dressing ways of the roller
縱切式
Rip cutting
生產量大（同一形狀工件批量生產）、高效率的一般用此方式 Suitable for large production output (volume production of a same implement)，and high efficiency | |
特長 Advantage | 臺階磨削砂輪磨損變大,修整一次砂輪磨工件少的用此方式 Large wear and tear of stage grinding wheel, one time dressing with less work piece use this method |
缺點 Disadvantage | 因為滾輪和工件形狀一致，所以不能加工其他形狀的物品 The roller has the same shape with its work piece, so it can’t process tools with other shapes |
橫切式
Cross cutting
修整砂輪形狀簡單，工件形狀簡單用此方式 Suitable for Simple shape o grinding wheel or work piece | |
特長 Advantage | 因為是小形的修整器所以便宜，可以加工多種形狀的物品 It’s very cheap as it’s small dresser, and can process many shapes tools |
缺點 Disadvantage | 於縱切式相比在修整上會多花時間，但在單石修整器的2～4倍的速度下可以修整 Compared with rip cutting, It takes longer time on dressing, but its speed is 2-4 times of single point dresser |
1.縱切式

2.橫切式
Cross cutting
縱向進給，沿滾輪軸向左右移動
Longitudinal feed or not, dressing roller moves left and right along roller shaft, see picture
