Line Boring Machines are designed for precision performance. The heavy duty cast-iron base provides stability for precise boring. Boring bars are hardened and chrome plated for rigid, straight boring. The direct tool setting capabilities provided on the machine minimize operator error. The line bore's versatility allows boring of overhead cam type cylinder heads, passenger car blocks, large diesel blocks and a wide range of other industrial uses. The 4-way adjustment of the boring head and columns simplifies set-up. The twin control panels puts the operator in front of the work for full control...
