Atlas Machine & Supply out of Kentucky, USA, took this picture from the AOD ring in the melt shop at a Very Steel Mill in Kentucky. The CLIMAX LM6000 liner/gantry mill was the perfect machine to repair the badly damaged seat areas that had been welded. The work is being performed 40′ (12.2 m) above the ground in a rough and extreme environment.

The CLIMAX LM6200 Linear/Gantry Mill:

This is CLIMAX’s most powerful portable milling machine. A revolutionary, heavy-duty mill that can be configured for linear or gantry milling in nearly any position! Modular bed sections allow the length to be expanded from 48 to 192 inches (1219.2 to 4876.8 mm) without losing rigidity (with 32 to 152 inches [812.8 to 4470.4 mm] of travel). Designed to handle demanding and difficult field machining conditions with features that ensure greater power, precision, and accuracy. Solid bed options are available.

The CLIMAX LM6200 Linear/Gantry Milling Machine revolutionizes both the capabilities and functionality of portable mills. Four main features make this one of the best milling machines on the market today:

Rigid, Modular Design

  • Unique modular bed design allows shorter bed sections to be combined to fit the length of the work area without losing rigidity.
  • Unique bed length section design provides superior rigidity across the entire bed length.
  • Connection plates and fasteners are optimized to provide the ultimate rigidity, even when the bed is extended by two or three times its original length.

Powerful, Precise Machining

  • Features heavy-duty spindle design and a choice of Hydraulic Power Units – a 25 Hp (18.6 kW) HPU allows use of cutter heads of up to 10 inches (254.0 mm) in diameter.
  • Milling can be done on any axis, with a milling head that can rotate 360° with an optional swivel plate for optimal spindle flexibility. An optional Z-axis slide assembly can be used for side milling and to increase the stroke needed for drilling or extended milling operations.
  • Fast, aggressive milling in horizontal, vertical, or inverted applications.
  • Provides reliable, precise milling to meet tight machining tolerances in both linear and gantry mill configurations.

Flexible Configuration & Operation

  • Innovative design allows the machine to be configured for traditional linear milling or simply split the rails lengthwise to configure for gantry milling!
  • Electric feeds can be mounted on the X, Y, or Z axis.
  • Machining capabilities include milling, drilling, and even boring.

Reduced Friction Rail Technology

  • Reduced friction rail system allows extremely smooth, continuous, and non-stick-slip travel.
  • Precisely machined and aligned rails with advanced lubrication make machining applications smooth and efficient.
  • A low friction system reduces maintenance costs and extends product life.
  • Precision ball screws in X, Y, and Z- axis assemblies allow precise location of the milling head.
