What Can A Laser Cutter Do? The Basics and What Materials Can Be Cut

Introduction

When it comes to manufacturing, choosing the right cutting technique is crucial for achieving the desired results in your projects. Whether you’re involved in rapid prototyping or full-scale production, the method you select will significantly impact the quality, speed, and cost of your operations. Two of the most popular cutting technologies in the industry are laser cutting and waterjet cutting. Each has its own set of strengths and weaknesses, making them suitable for different applications.

In this article, we’ll explore the fundamental differences between laser cutting and waterjet cutting, analyze their advantages and disadvantages, and help you determine which method is best suited for your specific needs.

How Each Process Works

Laser Cutting

Laser cutting is a subtractive manufacturing process that uses a high-powered laser beam to cut through or engrave materials. The process involves focusing a laser—essentially a concentrated beam of light—onto a small area of the material. The energy from the laser heats the material to the point where it either melts or vaporizes, creating a precise cut.

This technology is incredibly versatile and can be used on a wide range of materials, including metals like stainless steel, aluminum, and mild steel, as well as non-metals such as plastics, glass, and wood. Laser cutting is particularly well-suited for projects requiring high precision, as the laser beam can achieve a cutting slit size as small as 0.006 inches (0.15 mm).

Waterjet Cutting

Waterjet cutting is a process that uses a high-pressure jet of water to cut materials. The water is often mixed with an abrasive material, such as garnet, to enhance its cutting ability. The waterjet is focused through a small nozzle, where it is expelled at pressures as high as 60,000 pounds per square inch (psi). This high-pressure stream of water physically erodes the material along the cut line, effectively slicing through it without generating heat.

Waterjet cutting is known for its versatility in cutting a wide variety of materials, including metals, stone, tile, rubber, foam, and cloth. Because it does not rely on heat, waterjet cutting is ideal for materials that are sensitive to high temperatures, such as plastics and composites. Additionally, it can cut much thicker materials than laser cutting, with optimal thicknesses ranging from 0.4 to 2.0 inches (10 to 50 mm).

Key Comparisons Between Laser Cutting and Waterjet Cutting

Material Capabilities

When deciding between laser cutting and waterjet cutting, one of the most critical factors to consider is the type of material you need to cut.

Laser Cutting

Laser cutting is incredibly versatile when it comes to materials. It is particularly effective on non-metals such as wood, acrylic, glass, and various plastics. However, laser cutting can also be used on metals like stainless steel, aluminum, and mild steel. The primary limitation of laser cutting is its struggle with materials that have different melting points or are reflective. For example, cutting highly reflective materials such as copper can be challenging because the laser beam is reflected away from the material, reducing its effectiveness.

Waterjet Cutting

Waterjet cutting has virtually no material restrictions. It can cut through almost any material, including metals, composites, stone, and even food products. Because it uses mechanical erosion rather than heat, waterjet cutting is ideal for materials that would otherwise be damaged by the high temperatures associated with laser cutting. Additionally, waterjet cutting excels at slicing through thicker materials, making it the preferred choice for projects involving thick metal plates or stone slabs.

Precision and Tolerance

Precision is another critical consideration when choosing between laser cutting and waterjet cutting.

Laser Cutting

Laser cutting offers superior precision, with a minimum cutting slit size of 0.006 inches (0.15 mm) and a processing tolerance of approximately 0.002 inches (0.05 mm). This high level of precision makes laser cutting the go-to choice for intricate designs, detailed engravings, and projects where tight tolerances are essential. The laser’s ability to create fine, clean cuts also means that less post-processing is required, further enhancing its appeal for precision work.

Waterjet Cutting

Waterjet cutting is also precise, but it does not match the fine tolerances of laser cutting. The minimum cutting slit size for waterjet cutting is around 0.02 inches (0.5 mm), and its processing tolerance is about 0.008 inches (0.2 mm). While this level of precision is more than adequate for many applications, it may not be sufficient for projects requiring extremely detailed cuts or tight dimensional tolerances.

Speed and Efficiency

The speed at which materials can be cut is another key factor that influences the choice between laser cutting and waterjet cutting.

Laser Cutting

Laser cutting is generally faster, especially when working with thinner materials. Cutting speeds can range from 20 to 70 inches per minute, depending on the material and thickness. This speed advantage makes laser cutting particularly well-suited for high-volume production environments where time is of the essence. The quick processing time also means that laser cutting is more efficient in terms of machine utilization, which can translate to lower overall costs for large-scale projects.

Waterjet Cutting

While slower than laser cutting, waterjet cutting offers other advantages that may outweigh its speed limitations. Waterjet cutting speeds typically range from 1 to 20 inches per minute, depending on the material and thickness. While this slower speed might be a drawback in high-volume production settings, it is often acceptable for low-volume, high-mix environments where the ability to cut a wide variety of materials is more important than sheer speed.

Potential Material Damage

The potential for material damage is an important consideration, particularly for projects involving delicate or heat-sensitive materials.

Laser Cutting

Laser cutting can cause burn marks and discoloration on certain materials due to the high temperatures involved in the process. These burn marks can often be removed through post-processing, but this adds an extra step to the manufacturing process. Additionally, the heat generated by the laser can create a heat-affected zone (HAZ) around the cut, which may weaken the material or cause it to deform.

Waterjet Cutting

Waterjet cutting is a cold-cutting process that does not generate any heat. As a result, there is no heat-affected zone, making waterjet cutting ideal for materials that would be damaged or weakened by high temperatures. However, the high-pressure waterjet can apply significant force to the material, which can cause small parts to deform or even fail to cut properly. This is particularly true for thin or delicate materials, where the force of the waterjet may be too much for the material to withstand.

3 Ways to Ensure Your Industrial Service Vendor can Handle Custom Machining Services

Searching “custom metal fabrication near me” is not enough to find a qualified and reliable vendor. It’s time-consuming to find an experienced vendor capable of providing the right services, especially when you need more time designing and building products. When custom machining services are needed, finding a vendor that provides quality metal fabrication and exceeds expectations is essential. Production times, false guarantees or receiving complex parts short of the necessary spec qualifications can drag projects out, leaving engineers juggling tighter project timelines between vendors and clients.

Instead, we’ve put together three ways you can review a custom machining services and quality machine repair service vendor, including top qualities to look for to get the quality custom machining services you need.

1. Review Prior Experience

A great starting place is asking, “Has your team worked on a project like this before?” While it may seem simple, experience is a great teacher. Benefits include vendors who foresee problems, efficiently execute projects and accurately provide complete timelines for projects. A shop that provides various industrial services is more likely to have the techniques and experience to create exactly what is needed for custom machine parts while anticipating any potential problems. An industrial services vendor’s range of products and services provides the first clue of what their team is capable of managing. Ask about experience, not only for the size of the project but also about customization levels. While a smaller shop may specialize in custom machining, they might not have the ability to produce at a high enough volume for another project. Likewise, many high-volume plants lack the ability to create custom parts as the volume of production cannot be interrupted. Either way, it’s best not to assume and hear for yourself about their prior experience as it pertains to current capabilities.

At Yarbrough, we provide industrial services from expert metal fabrication, machine maintenance, engineering, part sales, and in-shop or on-site heavy equipment repair. We’ve also been doing this for over 75 years – giving our teams the experience and expert knowledge to become a one-stop shop for any project. Our high-tech equipment and expert-level knowledge in metal forming and bending has allowed us to work on various projects, from custom machining services to quality machine repair. We offer intricacy in designs and customization of parts — we consult directly with our clients to ensure we successfully execute any and all complex projects.

2. Discuss the Project Specs

The scale of a project for custom machining services greatly affects how vendors approach projects and can also have a large impact on the ability to give attention to details and produce high-quality parts. Some engineers default to high-volume plants for larger projects, but this is not always the best approach. Since these shops deal with many customers, they cannot provide the same quality level of parts and are more liable to produce parts that don’t meet the spec standards set. Yes, it may save a smidge of the budget, but the time spent to have to reevaluate with the spec standards aren’t met is much more costly. Smaller shops are an excellent resource for large projects since they have the same resources to get the work done but have the ability to evaluate complex instructions with more attention to detail.

At Yarbrough, our capabilities extend beyond simple fabrication. Our on-site hydraulics and machining divisions can produce the same volume as larger shops, but can also provide complex, custom machining services and quality machine repair.

3. Consider Project Execution

When dealing with complex custom parts, it’s important to understand the standard operating procedures and processes a vendor has in place to produce what you need accurately and on time. Quick reference guides, project checklists and quality control standards are all great topics that should be brought up for deeper conversation.

At Yarbrough, we pride ourselves on technical precision and efficient workflow. When these two combine, the result is that projects are executed to meet all specifications while delivering on project deadlines.

With a long-standing reputation for excellent customer service, Yarbrough is committed to listening to your needs and executing projects with precision. We build long-standing relationships with our customers as they grow to rely on us time and time again. A Yarbrough partnership means you can redirect your focus where needed most while we focus on the work.

How to Source Custom Components and Parts With The Right Vendor

Engineers are problem solvers. They find a way to create something that meets a need through ingenuity and technical expertise. However, a new problem arises when trying to figure out how to bring the concept into the physical world. How to find the resources to make the custom components?

1. Figure Out Where

Many engineers have searched for ‘custom metal fabrication near me’ and see numerous results. But parsing through those results can be quite cumbersome. Parts might come from contract plants, machine shops, in-house services, or even brokers looking to connect companies. Local machine shops provide the most options for genuinely custom machined parts. Unlike contract plants that often use assembly lines or in-house shops with less equipment, a machine shop will host a wide range of tools and technology to meet any customization need, like a custom metal laser cutting machine. Their ability to use a range of machines and methods means buyers aren’t limited to just small custom machined parts but can add functionality like hydraulics without using a second location.

2. Ask About Timing

Machine shops know that time is essential and often spread between many projects at once. It’s important to be confident that the part is right the first time and meets the exact specifications required. So while timing can vary by project, some vendors will consult with clients to establish a timeline that won’t make false promises and helps efficiently get work done right. Fast turnaround time is essential, as is high-quality work. An up-front and in-depth discussion between client and supplier helps ensure both are provided.

3. Check The Work

Vetting vendors can be a time-consuming process, and the last thing busy managers need is to do this process repeatedly, trying to find quality work. Touring facilities and consulting with fabricators are significant steps in ensuring trust in the process. Through these discussions, companies can rule out any potential issues and make sure every design step is understood and in good hands. Vendor reputation can also be a valuable indicator of quality.

Custom machined part orders can have much more detail than the drafted design. In addition to size and shape, there are product qualities like material and grade, product finish and construction style and type. Translating a sketch or even a 3D rendering into a completed product can require considerations that are not always immediately apparent. A vendor with knowledgeable technicians will watch out for these factors, and one with a wide range of equipment protects against assembly line inaccuracy.

No matter what parts a company is looking for, the right vendor is critical to ensure that the full design is done well. The right vendor will work with clients to understand their needs and source a project appropriately, whether that is obtaining parts from a manufacturer or creating them through custom fabrication.
