Used for Long Tables
This standard specifies the size and size of combined machine tools (long tables also known as long tables). This standard applies to the total length of the combined bed and the nominal size of the columns and sliding parts. The support is based on the required length of the corresponding platform surface as 8 as the nominal size, divided into 100mm, 125mm, 160mm, 201mm, 250mm types, the interchangeable size of the columns shall comply with the table and figure requirements, the table shows the length of the columns and the length of the platform surface. The installation of the sliding platform is ||Width of column
