Laser Cutting Service

Accumet Is Equipped to Handle Your Toughest Laser Cutting Jobs

Accumet of Westford, MA (near Boston, Massachusetts) is a fully equipped, industrial laser cutting service center with the most skilled laser-machine technicians in the country. Accumet's staff are experienced and capable of laser cutting to the demands of high reliability and repeatable aerospace and medical standards, including precision laser cutting of microelectronics and medical devices. Moreover, Accumet provides fast turnaround on a wide range of in-stock materials, including aluminum nitride (AlN) ceramic substrate materials, frozen epoxies, EMI and microwave absorbers, stainless steel tubes and adhesives. 

Our team is equipped with state-of-the art, computer-aided drafting and computer-aided modeling (CAD/CAM) software for highly accurate design and laser cutting tolerances machine control. Accumet leverages these tools alongside micro-positioning tables, multiple-beam systems, and statistical processing controls to deliver extremely repeatable and exact laser cut tolerances from part to part and job to job. Also, Accumet is willing to go above and beyond for their customers, and has even customized special laser systems, fabricated new rotary laser cutting, drilling, and marking machines, and developed advanced analysis tools to ensure part quality.

Accumet is home to more than 26 low-power, medium-power, and high-power CO2, YAG, and diode/fiber lasers, and we employ highly skilled and experienced laser-machining professionals to optimize the operation of every machine. Our laser-cutting machines can achieve micron-level cutting precision of thick sheets of high-strength stainless steel down to extremely delicate, intricate, detailed, precise cuts on thin foils, fabrics and a wide variety of other materials.

Combine our Laser Cutting Service with CNC Machining

By definition Laser cutting, or laser-beam machining, uses the thermal energy of a directed laser beam to vaporize, thermal-stress crack, melt, or burn a material away from a targeted area. Paired with modern CNC machine technologies, laser cutters can be used for highly precise micromachining, as well as high-volume and large-format cutting. As laser cutting is a non-contact form of machining, unlike milling, sawing, waterjet cutting, etc., no material is scraped, deposited, or ejected toward the part or work surface, which enables laser cutters to maintain extremely consistent and fast-cutting operations with little downtime or tool change, and offers the CNC machinist superior components to work within secondary processes.

The laser-cutting beam is also very narrow, leading to kerf widths as small as thousandths of an inch, depending on the material, laser power, and laser optics. Moreover, laser cutting can also cut material to very fine surface finishes in the range of just over a hundred microinches, at a minimum. For some materials, the thermal-cutting effect of a laser can be considered a flame-polished edge. The highly precise and no-vibration cutting that lasers provide also can reduce the post-processing needed to refine a part, which can be especially time-consuming when attempting to polish small dimensional areas of intricate parts after CNC milling.

Though the speed of a laser-cutting machine depends on the material, material thickness, laser type, laser frequency, and laser power, some laser-cutting jobs can often be processed at greater speeds than CNC mills, especially when sheet thicknesses require the CNC mill to perform multiple passes to complete a cut. As laser cutting is zero-contact without any additional forces placed on the workpiece, fixturing effort can be reduced significantly, and more consistent parts can be produced. Lastly, laser cutting produces a very small, heat-affected zone (HAZ) that may also be far lower in temperature than traditional cutting technologies that rely on shearing or grinding friction to cut.

Laser Cutting Can Be Performed on a Wide Range of Materials and Thicknesses

Unlike many other machine-cutting technologies, laser cutting imposes almost no forces and stresses on the work material. This means that even very delicate and thin materials, such as leather, silk, and even thin precious-metal foils, can be cut with precise and intricate designs. For many materials, the small, heat-affected zone (HAZ) and thermal stresses imparted on the material enable cutting patterns that would otherwise be impossible with other methods.

However,  the max cuttable thickness or laser cutting tolerance limits must be considered prior to any laser cut, and these tolerance limits depend on the material. Also, certain highly reflective and translucent materials may be difficult or impractical to laser cut. There are different types of lasers, namely UV, IR, and Far IR, in which the frequency of light used in the laser processes materials in varied ways.

Standard Max Laser Cut Thicknesses and Laser Cutting Tolerances by Material:

Material                

 Max Cuttable Thickness
Stainless Steel         0.375" (3/8th inch)
Plastics   0.75" (3/4 inch)
Wood 0.75" (3/4 inch)
Ceramic 0.125" (1/8th inch)

 

Competitive Laser Cutting Service Costs and Extremely Fast Turnaround Times

With precision laser cutting there is no direct mechanical force on a part and no direct processing that produces residual material that can cause damage.  Fixturing and setting up a precision laser-cutting job can be done very rapidly even with very tight tolerances. Depending on the material and the job, laser cutting parts and materials can also be precision laser cut and finished in a single step, removing the need for time-consuming and costly secondary post-processing.

We're located just north of Boston, Massachusetts in Westford, MA, and proudly service the entire US with many laser cutting, laser drilling, laser welding, laser marking, laser etching and precision polishing, and secondary processing services. All of our materials are stocked in-house for optimal convenience.
