Through the operation panel, not only can realize the fixed distance and constant pressure of two kinds of forming process, and can realize a pad, pad free, top three cycle process.
通过操作面板选择，不仅可实现定程、定压两种成形工艺，而且可实现有垫、无垫、顶出三种工艺工作循环。

In addition, a method of forming the polishing pad and a method of polishing a surface with the polishing pad is disclosed.
另外，本发明还公开了形成抛光垫的方法以及用抛光垫抛光表面的方法。
