Our Equipment & Skilled Machinists
Our Skilled Technicians are experienced in utilizing the following machines and equipment
.

American
Engine Lathes
Used for precision machining, cutting, and shaping various materials, while rotating the workpiece about an axis. Our engine lathes can handle large critical components such as turbine runner shafts, wind turbine shafts, suction rolls, wind turbine bearings, and ship shafts.
- Max. swing diameter: 78 ¾”
- Between centers: 482”
- Max. Chuck diameter: 62”
- 9 Engine Lathes
- Poreba, Lodge & Shipley, Monarch Engine Lathes

CNC Lathes and Programming
CNC stands for Computer Numerical Control and refers to a machining tool that is operated by a computer system. CNC Lathes are used to produce round shapes with an outer diameter(OD) and inner diameter (ID), and various structures based on precise design instructions and machining specifications.
- Swing over Carriage: 13 ¼”
- Centers: 78”
- Swing over ways: 16”Toolmex

Vertical Boring
machines
Used for turning and boring large and heavy industrial workpieces, such as water turbine runners, large pipe flanges, steel rolls and cylinders, and machine turbine casings. The workpiece is held on a horizontal table that rotates along a vertical axis, while the boring head moves linearly.
- Max. swing diameter: 104”
- Vertical under rail: 85”
- 4 vertical boring mills
- Giddings & Lewis, Bullard Vertical Boring Mills

Horizontal Boring machine
High precision equipment used to modify industrial parts and components by drilling, boring, milling, and grooving various types of steel and alloys in a horizontal direction. It allows for large parts to be machined fast and accurately and also allows machinists to reach small cavities easily.
- 5” Spindle Diameter
- 60” x 120” Table
- 103” Cross Table Travel
- 6 horizontal boring mills

Roll Grinder
machines
High precision machines used to grind smooth and textured rolls and to very tight tolerances. Roll grinding machines consist of a bed, head frame, tailstock, bracket, vertical and horizontal carriage, grinding head, measuring frame, and an electric numerical control system.
- 44” OD
- 312” Face
- Computer controlled Crowns
- 8” Superfinisher
- Farrel, Lobdell Grinding Machines

Dynamic & Static Balancing Machine
Used to balance the moving parts of a machine or piece of industrial equipment by rotating these parts at high speeds or adding various counterweights. Roll Balancing is critical to minimizing vibrations and bearing replacements, optimizing the overall machine performance, and extending the life of the equipment.
- 96” Swing x 552” Length
- 3-Plane Capacity
- Schenck Trebel Balancer
