Description
図1は、本発明の一実施形態による精密ロール旋盤を示す側面図で、図2は同精密ロール旋盤の平面図である。
図1および図2において、参照番号10は、ベッドを示す。このベッド10の上には、主軸台12、心押台14、往復台16が配置されている。工作物はロール形状のロールWであり、主軸台12と心押台14とで回転自在に支持されている。
主軸台12は、ベッド10の長手方向の一端部に配置されている。この主軸台12は、本体部17と、主軸18と、この主軸18の先端に取り付けられたチャック19と、主軸18を駆動するサーボモータ20を含む。主軸18は本体部17に内蔵されている図示しない油静圧軸受により支持されている。チャック19は、ロールWの軸を把持し、主軸19の回転をロールWに伝達する。
往復台16は、ロールWの軸方向に移動可能にベッド10上に設置されているサドル26を含む。このサドル26の上には、ロールWの軸方向と直角の方向に移動可能にテーブル28が設置されている。本実施形態の精密ロール旋盤では、サドル26を送る軸がZ軸で、サドル26上でテーブル28を送る軸がX軸である。そして、この精密ロール旋盤では、X軸、Z軸の他、主軸台12にはC軸、テーブル28に設けられた刃物旋回台30にはB軸が設けられており、合計4軸制御の工作機械である。
なお、サドル26を送るZ軸送り駆動装置と、刃物旋回台30を搭載したテーブル28を送るX軸送り駆動装置はともに、リニアモータから構成されている。図3において、参照番号47は、X軸送り機構のリニアモータを構成する永久磁石列を示し、48は、Z軸ガイドレール42と平行に延びる永久磁石列を示す。
図6は、ロールの表面に加工する凹凸パターンを示す図である。この図6に示すように、四角錐、いわゆる四角ピラミッドが縦横に配列した凹凸パターンである。
このような四角ピラミッドのパターンは、基本的に縦溝60と横溝62との組み合わせにより加工する。そして縦溝60を一定のピッチで連続して加工し、その後、縦溝60に交差させるようにして、横溝62を一定のピッチで連続して加工することにより、ロール表面には四角ピラミッドが縦横に配列したパターンが形成される。
