Introduction• One of the most versatile machine tools;
used to bore holes in large and heavy parts as engine frames, machine housings etc which are practically impossible to hold and rotate in an engine lathe or in a drilling machine.
• Also drilling, milling and facing can be preformed with equal facility.
• Along with attachments screw cutting, turning, grinding or gear cutting can also be performed.

Types
1. Horizontal boring machine:• The work is supported on a table which is
stationary and tool revolves in a horizontal axis.• Can perform boring, reaming, turning, threading,
facing, milling , grooving and many other operations with suitable tools.
• Work piece which are heavier and asymmetrical can be easily held and machined.
• Different types has been designed to suit the different purpose.

Types
2. Vertical Boring Machine:• The work rotates on a horizontal table about a
vertical axis and the tool is stationary except for feed.
• Machine may look like a vertical lathe.• Larger diameter and heavy work pieces, can
be set up more quickly than in lathe.
• Multiple tooling may be adapted with its turret type tool post, increasing the rate of production.

Precision Boring Machine• It uses a single point cutting tools to machine
surfaces rapidly and accurately.• Cemented carbide and diamond tipped tools are
operated at a very high cutting speed to produce accurately sized holes with fine surface.
• Jig boring machine is a precision boring machine, resembles to vertical milling machine in construction.
• Accurate positioning of holes is achieved by Lead screw method or Mechanical / Electrical Gauging method or Optical measuring method.
