Laser Cutting

Mainstay offers exceptional laser cutting services, specializing in mild steel, stainless steel, and aluminum materials. We pride ourselves on continuously improving our fabrication capabilities to maximize efficiency and productivity.

To keep up with new demands, we replace or add laser-cutting equipment every three years. Most recently, we invested in a new Trumpf Fiber Laser Cutting Machine with BrightLine Fiber function. The machine has increased our cutting capability and our capacity as relates to cutting.

Plasma Cutting

An alternative to laser cutting, a plasma cutter can cut some materials that a laser cutter should not, such as highly reflective metals. The plasma machine also cuts thicker material faster at a reduced cost.

Mainstay uses a KOMATSU TFP 3051 high definition plasma cutting system. It operates by blowing inert gas at a high rate out of a nozzle. It creates an electrical arc which changes the gas to plasma. The plasma melts the material and moves as the molten metal is blown away from the cut.

The honing process provides ultimate precision by scrubbing an abrasive stone along a controlled path. Honing can improve the geometric form of a surface which allows for a more precise fit.

Mainstay's honing processes work with such precision that excessive calibration is not needed. The honed component will often have an accuracy that exceeds the tool used to create it.

CNC Milling

CNC milling is similar to drilling and cutting, but allows for greater precision than other machines. A milling machine can move along multiple axes to create a variety of shapes.

From prototypes to parts for short-run production, Mainstay's CNC milling services accommodate a wide range of manufacturing needs.
