Giddings & Lewis PT series horizontal boring mills

Giddings & Lewis PT Series horizontal boring mills are the machine of choice for producing a wide range of parts. Flexibility is the hallmark of this series. Capabilities may be readily expanded with the addition of rotary tables or effective attachments such as contouring heads and programmable boring bars. 

Advantages of table-type horizontal boring mills

  • Substantial weight capacity – table handles parts weighing as much as 40,000 kg
  • Rigid machining platform with one-piece column base and bed.
  • High performance drive and way system provides both superior stiffness and allows fast traverse – 25 m/min
  • Modular design – select machine features and capabilities based on applications. Choose from three headstocks – two or four-speed, 130 or 155 mm diameter

Applications and Operations

Manufacturers worldwide are benefiting from the capabilities of the G&L PT Series of horizontal boring mills. Job Shops and Tool and Die producers appreciate the versatility. Oilfield and mining equipment manufacturers take advantage of the large capacity and heavy-duty cutting. With decades of expertise, our application engineers are prepared to help you develop a solution for your manufacturing challenges.

  • Read how a Tool & Die customer used a Giddings & Lewis PT Series HBM to add capacity – Application report
  • The rigidity of Giddings & Lewis boring mills makes it possible to take heavy cuts. 
  • Programmable boring bars and contouring heads add machining versatility and reduce the number of tools needed by adding turning capabilities to live spindle HBMs and HMCs. The video demonstrates how these attachments handle a variety of part features.

Available options:

  • Contouring heads and programmable boring bars
  • Right angle heads
  • Attachment racks
  • High-pressure coolant through the spindle
  • Large capacity tool magazines
  • Tool and part probes
  • Controls – Siemens, Fanuc or Heidenhain
