Line Boring Machine

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 during the boring process.
The infinitely variable spindle selection combined with choice of feed, gives the operator precise control of the bore finish.
Extra long boring spindle travel maximizes the boring capacity with just one tool setting.

Bed

Heavy bed made of stress-relieved steel to assure stability and vibration free boring

Workpiece setting up

Approximative centering by means of cones and final centering by means of two universal centering device with dial indicator
A bridge comparator holder secures a perfect alignment of boring bar as to the block surface

Workhead

Workhead is mounted on a vertical and trasversally adjustable support to allow a fat and accurate alignment
Control grouped in the head for an easy and handy operation
Boring spindle with two limit stops
Automatic workhead lubrication
