Description

Designed for precise machining of internal diameters from 0 to 80 mm. The carriage includes two tool seats: one central seat (H1 tool) for boring diameters up to 50 mm and another lateral seat (H2 tool) for diameters from 50 to 80 mm.

This head must always rotate to the right (clockwise) to advance in the indicated direction (figure no. 9).

The H1 and H2 tools are aligned between their cutting edge (no. 7) and the orientation mark (no. 8). The H1 tools are locked with a fixing screw (no. 1) and the H2 tools in the same way (no. 2).

For micrometric adjustment of the boring tool, it is recommended to:

• Loosen the screw (no. 6).
• Turn the vernier ring (no. 5) until the “0” aligns with a full division of the ring (no. 4).
• Tighten the screw (no. 6).
• Loosen the screw (no. 3).
• Turn the ring (no. 4) back approximately ½ turn and advance it to the previous position plus the value of the desired cut using the vernier divisions (no. 5).
• Gently tighten the screw (no. 3).

The screw (no. 1) should tighten the boring bars and collets exactly 90° from their full cut.
