APPLICATION SPOTLIGHT: SLEW RING REPAIR

APPLICATION SPOTLIGHT: SLEW RING REPAIR

Keith Malencia from Ginger Hill Portable Machining and Metrology in Pennsylvania, USA, using a CLIMAX FF8200 flange facer to remachine a CAT5130 bearing surface. These bearing surfaces require repair after getting damaged, corroded, or worn out over time. These surfaces are commonly found on draglines and other rotating diggers and mining/heavy construction equipment.


The CLIMAX FF8200 Flange Facer Solution:

A true workhorse, with the size and muscle to machine large-diameter flange faces. It gives up nothing in accuracy thanks to its rigidity, easy positioning, and uniform rotation rates, even when mounted in vertical flanges. Features a tool head that can be rotated a full 360°, infinitely variable feed rates, and remotely adjustable air-powered feedbox so radial and axial feeds can be done quickly and safely. Facing AND milling diameters range from 45 to 120 inches (1143 to 3048 mm).

PRODUCT ADVANTAGES:

  • Rugged Machine Design
  • Large, heavy-duty construction-grade bearings provide powerful, rigid performance throughout the entire machine-facing range, even machining over bolt hole patterns.
  • Oversized ring gear accommodates extremely high torque levels for challenging flange repair applications, and these machines are able to generate a phonographic finish.

Flexible and Versatile

  • Both radial and axial feed are achieved with a pneumatic feedbox. Manual feeding for rapid positioning is also possible.
  • Feed rate is adjusted remotely at the pneumatic conditioning unit, providing the ultimate operator safety and the flexibility for feed rate adjustments even during machining operations.
  • Infinitely variable feed rates from 0.002 – 0.035 inches (0.0508 – 0.889 mm)/rev provides operational flexibility.
  • Reversible feed box can be mounted to provide either radial or axial feed.
  • Turning and counterweight arms can both be adjusted for the desired swing clearance and machining range.
  • Tool head can be rotated a full 360˚ providing the ability to create a variety of chamfers, O-Ring grooves, lens rings, and other angular surfaces as needed.
  • Pneumatic & hydraulic drive options are available.
  • Chucking system can be removed to allow the flange facer to be face-mounted.
  • Can be mounted both OD and ID or surface-mounted.
  • Milling option available with precision down-feed ball screw.
  • Back-facing attachment is available for heat exchanger repair.

Quick and Easy Setup

  • Modular design allows many of the machine components to be removed to facilitate easier setup and storage.
  • Unique chucking system minimizes parts to greatly simplify machine setup and tear down.
  • Quick-adjust leveling feet make setup quick and easy.
