Abstract
Description
このことからもわかるように、水溶性切削油に求められる性能は冷却性、すなわちそれを活かした加工性である。もし冷却性が不十分であると、加工時に熱が除去されず被削材が工具に溶着して加工不良となる場合がある。また、水溶性切削油剤を安定して使用するために、乳化安定度や耐腐敗性も重視される。乳化安定度が不十分であると、油剤が水と油分に分離してしまい、設計通りの性能を得ることができないだけでなく、切削された金属の摩耗粉が凝集して材料に付着する場合もある。こうなると後工程での除去が必要となるため生産性が低下してしまうこととなる。耐腐敗性も重要な性能で、水を多く含んだ水溶性切削油は菌やカビが繁殖しやすく、腐敗すると性能が低下したり、その臭気により作業環境を大幅に低下させたりすることとなる。
[1]原液組成物全量を基準として、0.3質量%以上7.0質量%以下の芳香族3級アミン類および複素環式3級アミン類から選ばれる少なくとも1種のアミン化合物と、0.1質量%以上5.0質量%以下の水と、70質量%以上98質量%以下の鉱油と、を含有する水溶性切削油剤原液組成物。

一方、鉱油の粘度は150mm2/sec以下が好ましく、100mm2/sec以下がより好ましく、80mm2/sec以下が最も好ましい。粘度が上記の上限値を超えると乳化安定度を損なうおそれがある。
本発明の第2実施形態に係る水溶性切削油剤組成物は、原液組成物全量を基準として、0.3質量%以上7.0質量%以下の芳香族3級アミン類および複素環式3級アミン類から選ばれる少なくとも1種のアミン化合物と、0.1質量%以上5.0質量%以下の水と、70質量%以上98質量%以下の鉱油と、を含有する水溶性切削油剤原液組成物を、水により5倍以上50倍以下に希釈してなる。なお、本実施形態における水溶性切削油剤原液組成物は、上記第1実施形態に係る水溶性切削油剤原液組成物と同様であり、ここでは重複する説明を省略する。

転造タップによるタッピング評価試験によりタッピングエネルギー効率(TEE)を求めることにより評価した。
材料はアルミニウム(AC8A)で行った。
工具はOSG社製 B−NRT B M8(ピッチ1.25)を用い、7.4mmの下穴に対し回転数360回転/分、送り速度9m/分で加工評価を実施した。
なお、基準油はJX日鉱日石エネルギー(株)ユニソルブルEM−Lとし、基準油、評価油ともに水道水にて20倍に希釈したものを使用した。
タッピングエネルギー効率とは基準油のタッピングエネルギー(加工時のトルク積分値)を評価油のタッピングエネルギーで割った値であり、下記式:
(タッピングエネルギー効率、%)=(基準油のタッピングエネルギー/試験油のタッピングエネルギー)×100
により定義される。タッピングエネルギー効率が100を超える油剤組成物は、基準油よりも加工性が良いことになる。本試験における評価基準は以下のとおりである。得られた結果を表1〜4に示す。
A:タッピングエネルギー効率が110以上
B:タッピングエネルギー効率が110未満105以上
C:タッピングエネルギー効率が105未満95以上
D:タッピングエネルギー効率が95未満
