Lahey Machine offers CNC milling, turning and water jet capabilities. Computer Numerical Control (CNC) machining is a manufacturing process in which pre-programmed computer software dictates the movement of factory tools and machinery. The process can be used to control a range of complex machinery, from grinders and lathes to mills and CNC routers.

Lahey Machine offers an aray of manual services to include milling, turning and broaching. Conventional machining processes rely on harder tools or abrasive materials to remove material from the workpiece. This is typically achieved using metal tools that cut or grind away material from the workpiece to create a desired shape. Lahey Machine offers an aray of manual services to include milling, turning and broaching.

Simply put, “metal fabrication” is defined as creating products or structures by cutting, bending, and/or assembling metal material. It’s largely considered a value-added process as it consists of putting together actual products or structures from metal raw material. With our water jet, machining, welding, and combined ninety years’ experience, consider Lahey Machine for your next fabrication project.

Over the years, Lahey Machine has been involved in many customized and one-off builds.  Some examples include hydraulic laydown trailers, purpose-built winches, pipe-lining machines, specialized vehicles, and many more. Talk to us about your unique needs and next custom build.

Lahey Machine offers GTAW (TIG, heliarc), and GMAW (mig, wire) welding operations on ferrous and non-ferrous metals.  Lahey Machine also staffs an R-stamp certificate holder.  This allows us to perform repairs and alterations to pressure vessels and boilers to name a few.  We also offer coded pipe welding if the need arrises.

The Twin Wire Arc spray process is one of the series of Metalizing processes. Metalizing is sometimes referred to as Surface Engineering wherein any number of alloys can be applied to obtain the desired result. Additionally, Arc Spray provides a proven and valuable cost-saving alternative to part replacement. By example, these processes are commonly utilized to affect the following results:

Enhancing the performance of any given part by applying a metallic coating that is more resistant to corrosion, erosion, oxidation, or wear, than the original part surface. Some examples include composite coating wherein Stainless Steel is applied to carbon steel components as a cost-saving measure. One key advantage is the capability of layering unlike materials and alloys, such as coating carbon steel with aluminum.

Restoring lost dimension to worn or mis-machined metal surfaces. Typical applications include the repair of worn or damaged shafts, bearing areas, seal surfaces, pump parts, rollers, engine block decks, and cam bearing areas, for example.

Grip surfaces can be applied to prevent slippage of material on production rollers in paper mills, blown film extrusion plants, print rollers, etc.

A special wire feeder introduces two opposingly charged wires that converge in a hand-held or machine-mounted torch to form an arc. As the arc melts the wires, a copious quantity of air or specialized gas is directed through the center of the arc, shearing off the molten droplets and propelling them onto the substrate where they coalesce. (Two differing wire compostitions can be used if desired to create pseudo alloy.) The coating produced can be used in the 'as sprayed' condition or can be finished by machining or grinding to produce the desired finish.
