  • Programmable boring bars
  • Programmable contouring heads
  • Minimized number of tools needed
  • Fully automatic tool changing
  • Industry leading traverse rates

Giddings & Lewis PT 1500/1800

High stiffness and ultimate versatility

The Giddings & Lewis PT Series of horizontal boring mills are ideal when high flexibility is required to process a wide range of parts.

Designed with a modular setup, you can choose from three different headstocks (two or four-speed, 130 or 155 mm diameter). Capabilities can be expanded with the addition of rotary tables or attachments, such as contouring heads and programmable boring bars.

Giddings & Lewis are renowned for producing the most rigid and accurate machining platforms in the industry. The PT Series machines have a stiff machining platform, comprising a one-piece column base and bed. In addition to high precision, high stiffness gives thesemachine tables a substantial weight capacity, with the ability to handle parts weighing as much as 40,000 kg.

The Giddings & Lewis PT 1500/1800 boring mills feature preloaded roller guide ways, which offer significant advantages over other types of way system.

Defense

Benefits include:

  • Double the load capacity and up to 10 times the life of ball-type linear ways
  • Lower friction
  • Enhanced positioning accuracy
  • Better circular/contouring accuracy
  • Low thermal growth for more consistent accuracy
  • Low maintenance and ease of repair

Giddings & Lewis RT 1250/1600/2000

High precision for heavy components

The Giddings & Lewis RT Series of boring mills are designed for exceptional versatility, making them a smart choice for a wide range of industries, including aerospace, automotive, mining and defense.

A modular set up means that you can choose the features and capabilities that you need for your individual production process.

With a built-in contouring rotary table and an additional axis, these machines are ideal for boring prismatic parts that require work on multiple surfaces. Meanwhile, the one-piece rigid machining platform, which is characteristic of all Giddings & Lewis boring mills, makes easy work of heavy, high-precision cuts.

The Giddings & Lewis RT 1250/1600/2000 models are robust, heavy duty boring mills with a substantial weight capacity. They can handle any part weighing up to 40,000 kg.
