Saddle – The saddle is mounted directly on the top of the base and slides over it. The column is mounted on the saddle. It can be moved up and down and swivelled to either side.

Table – The table resets and moves on a top base, which is mounted over the saddle. The table has two layers. The worktable is mounted on the sub table which has ‘T’ slots for mounting the work and attachments used on the machine. The worktable can be swiveled while grinding tapers.
