Understanding CNC Laser Cutting Machines

September 30, 2020

Laser cutting technology, as the name suggests, uses a powerful laser to efficiently cut materials. It’s a fabrication process which utilizes a high-powered laser beam to cut materials with great speed and accuracy. While traditionally used for industrial manufacturing applications, laser cutting is now increasingly used by small businesses and hobbyists. Laser cutters can be used to cut a range of materials: metal, plastic, wood. Glass, gemstone, and paper. It can produce intricate and complex parts without the need for tailored tooling. 

Lasers are used for a broad range of applications – cutting metal plates is just one of them. Laser cutting machines produce incredible results when it comes to cutting steel, stainless steel, and aluminum plates. For example, the process yields a small kerf width, excellent cut quality, and a small heat-affected zone. Besides, you can cut very intricate shapes and holes. 

CNC Laser Cutting Machine 

A CNC machine is a programmable device that is capable of autonomously performing various tasks. A CNC laser cutting machine is controlled through written code which determines everything from RPMs to the movement of the cutting head. All CNC machines are run by computers. The function of a CNC machine is to take human input and translate it into movements through code. CNC laser cutting machines outperform every other cutting tool when it comes to repeatability and precision of the manufacturing processes. 

Laser cutting is one of the most widely used manufacturing processes that have applications in automotive, aerospace, semiconductor, electronics, and medical fields. The cutting technique works in many different ways as compared to how old cutting technologies work, opening up new possibilities for quality and reliability. 

The CNC programs command the following actions in a machine based on human input:  
  • How fast to move the cutter 
  • How fast to turn the spindle 
  • The direction in which the cutter moves 
  • Which cutter to use 
  • When to turn on or off the coolant and so on 
Types of Laser Cutting 

Fabricators use a variety of laser cutting machines that can be categorized as a liquid, gas, and solid-state lasers. Cutting techniques are differentiated based on the active laser medium. The two major types of laser cutters use solid-state lasers and CO2. A CO2 laser is ideal for cutting non-metal materials as the early models were not powerful enough to cut metals. However, the latest CO2 lasers are now capable of cutting metals. Most fabricators use these machines to cut non-metal and organic materials such as leather, wood, and rubber.

Accurate Metal Fabricating

September 23, 2020

Accurate metal fabricating is a broad subject that covers several areas. Generally speaking, the term metal fabrication refers to the strict manipulation of metals based on exact specifications and tolerances. The process involves, but is not limited to, CNC machining, metal spinning, cutting, welding, punching, rolling, molding, and bending. These processes are used to turn raw materials or semi-finished materials into final products.

Metal fabrication has broad applications across consumer products and industries. Flat metal, plate metal, sectional metal, fittings, castings, and welding wires are some of the standard raw materials used to build a wide range of products. 

What is Accurate Metal Fabricating? 

As the name suggests, accurate metal fabrication refers to the production of metal components using highly specialized techniques and equipment such as CNC precision machining, laser cutting, sheet metal fabrication, precision grinding, plasma cutting, etc. When it comes to precision, fabrication using computer numerical control (CNC) is a commonly used method. 

The need for precision and accuracy is continuously increasing across industries. To meet the emerging demand for precision machining, shops have to employ sophisticated and multiple technologies to help contractors limit their need to work with several vendors to complete a project. 

Many modern metal fabrication processes require precision with near-zero tolerance for error. They start with an initial design idea and creating a fully functional and tested prototype. Once completed, the above-mentioned accurate metal fabricating techniques are used to convert raw stock into finished products. 

How VeriForm creates unique parts using precision metal fabrication 

VeriForm is a leading fabrication shop in Canada, developing custom metal structures using advanced metal fabrication equipment. The shop provides a complete range of parts fabrication services in one facility so that clients don’t have to locate multiple vendors to complete projects. 

As one of the best custom fabricators in Ontario, VeriForm uses a highly trained team of machinists and technicians who know how to use precision equipment to produce and assemble the most complex parts. Here are some of the accurate metal fabricating processes VeriForm uses to produce great results for their customers: 

  • CNC Hi-Resolution Plasma Cutting
  • CNC Laser Cutting
  • CNC Punch/Laser
  • CNC Bending – Forming
  • CNC Shearing
  • CNC Punching
Method of production 

One of the common accurate metal fabricating techniques include precision metal stamping, a process in which three-dimensional parts are engraved onto a piece of metal. The process requires high pressure to stamp various shapes and dies onto metal surfaces. A range of metals including metal alloys, steel, copper, aluminum, and titanium can be processed using precision metal stamping. The gear used to get the job done can range from a simple, manual press to a more sophisticated computerized die processor. 

Computer-based metal fabrication techniques process instruction to run mechanical devices. CNC or computerized machines are a lot more efficient than traditional machines. The concept of accuracy has primarily developed with the advancement of industrial technology that depends largely on computers and robots. 

The growing need for accurate metal fabrication 

When operating in a highly competitive environment, it becomes crucial to deliver top quality products on time. Precision fabrication is the only way forward to deliver premium products. However, delivering projects on time depends on the project management capabilities of a shop. While the market has become too competitive, fabricators grow when they stop being mediocre and focus on precision and customer satisfaction. 

Precision metal fabrication processes are not all about machines. Fabrication skills play a critical role in this regard. For example, in laser cutting, operator skill is a part of the equation. A nozzle that really isn’t centered, a feed that isn’t optimal or a focus point isn’t where it should be will make all the difference. VeriForm works hard to be a cut above the rest with quality, on-time completion, and customer satisfaction. 

What types of CNC machining are offered at VeriForm?

August 22, 2020

CNC (Computer Numerically Controlled) machining is a specialized manufacturing and fabrication process that uses computer software to direct the movement of shop tools and machinery. Like manual methods, it machines a workpiece into a desired shape and size, but CNC sheet metal fabrication is rapidly becoming a preferred solution for the following reasons:

  • Greater accuracy: The machinery is guided by very precise computer-driven variables, which leads to greater accuracy in the final product. The same CNC programming can be used again and again to produce identical results while eliminating unnecessary waste, which is a bonus for mass-produced tools and components.
  • Safer operation: CNC machines are generally safer to operate because the employee works behind a guard or safety door. The process is not hands-on, which decreases the possibility of an accident.
  • Cost-effective to run: With traditional machining, one operator is needed per machine. The CNC method requires fewer operators because one person can operate several machines at the same time.
  • Improved efficiency and faster output:  Unlike manual methods, the CNC process is automated, which increases production speed and manufacturing quality. Being machine-driven, the production cycle can continue for the entire shift without having to stop for a break.

At VeriForm, we specialize in four CNC sheet metal fabrication processes at our 26,000 square-foot facility in Cambridge, Ontario. Below is an overview of each application, what it’s used for, and how it can benefit your next project.

CNC Countersinking

When you’re fabricating parts that will later accommodate a rivet, screw, bolt, or other fastening device, that device needs to be able to sit flush with the surrounding metal. Our CNC Countersinking machine creates a conical hole that allows screw or bolt heads to sink into the metal, resulting in a smooth and professional finish for all of your parts.

CNC Drilling

CNC drilling uses computer input to efficiently and accurately drill holes into strong materials like metal. Its fast delivery, combined with the precise results that CNC machining is known for, makes it a staple in facilities with high production rates and even higher quality standards. At VeriForm, our state-of-the-art CNC drilling process creates clean holes in metal up to 1 1/2” inches in diameter, making us the machine shop of choice for custom parts fabrication as well as projects that rely on the highest degree of machining accuracy.

CNC Laser Cutting

When used to shape sheet metal, CNC laser cutting machines are highly accurate, yield superior cut quality, and have a small heat-affected zone, making it easy to cut tiny holes and complex shapes. Advantages include:

  • Greater accuracy compared to plasma or flame cutting
  • Minimal warping
  • Speedier processing and production timeframes
  • More parts per sheet due to small cutting diameter
  • Cuts non-metallic materials that cannot generally be cut by plasma or flame cutters

The specialists at VeriForm have been using CNC laser cutting machinery for over two decades. We can cut up ¾” x 80” x 160” with accuracy of +/- 0.005”, so you can rest assured that your next project will yield stellar results.

VeriForm Metal Fabrication Guide

July 26, 2020

Do you need a metal sculpture that turns heads and emphasizes its surroundings? Or perhaps you need parts or other custom fabrication work specific to your industry? At Veriform, our experience and state-of-the-art equipment enable us to offer the highest quality fabrication services for a wide spectrum of projects, from one-of-a-kind architectural centrepieces to large-scale production runs of routine parts and components.

Instead of using ready-made parts to assemble custom metal structures, we use innovative and efficient cutting, bending, and welding machinery at our 26,000 square-foot facility in Cambridge, Ontario. In this blog, we present a metal fabrication guide that details the main processes we employ for our customers, most of which are CNC-driven.

What is CNC machining?

CNC machining refers to fabrication machines that are directed by computers programmed with G-code, which controls process features like coordination, location, feed rate, and speed. When customers provide us with a 2D or 3D CAD drawing, it is translated into computer code and programmed into the software, which directs the machinery. The output is consistent and produced at a speed that manual fabrication would be hard-pressed to replicate.

CNC Hi-Resolution Plasma Cutting

Plasma cutting uses a combination of gases to carry out the cutting process. High-resolution plasma is the latest in this cutting technology: directed by a program like Fusion 360, the plasma arc is forced through a small nozzle to create cleaner edges. Modern hi-resolution plasma machines can cut carbon steel up to 76mm thick and, thanks to their automation capability, deliver quality results quickly and efficiently.

CNC Laser Cutting

Unlike plasma cutting, which uses gases, CNC laser cutting uses a laser beam to cut and shape workpieces. It has several advantages over flame or waterjet cutting methods, including a reduced heat-affected zone and lower power requirements. CNC lasers can accurately and affordably cut a wide range of materials, even non-metallic ones that cannot usually be cut by plasma or flame processes. At Veriform, our laser cutting service cuts up to ¾in x 80in x 160in with accuracy of +/- 0.005in. 

CNC Punch/Laser

Our CNC punch/laser machine delivers the benefits of both punch and laser processing in a compact footprint, dispensing with the need for standalone machines. By combining a high-efficiency laser with a punching press for creating holes or indent forms, this unit makes sheet metal fabrication much easier. It also reduces run time by eliminating additional processes and optimizes material handling.

CNC Bending – Forming

At Veriform, we offer CNC metal bending and forming services that use hydraulic press brakes, detailed tooling, and comprehensive CAD/CAM capabilities. The press brake forces sheet metal between a punch and die and applies a bending force that can shape and form workpieces up to 21 feet. Our detailed selection of bending tools can handle everything from the most basic to the most complex bends for your project.

CNC Shearing

We use CNC shearing to cut sheet metal to size out of roll stock and other types of larger stock. When a force is applied perpendicular to the material, it yields and breaks. This process is typically used as the first step in preparing metal stock for stamping processes or getting smaller blanks ready for presses.

Welding

Not all of the processes in our metal fabrication guide are directed by computer! At Veriform, we only employ welders who are CWB CSA W47.1 and W59 certified and retain an experienced welding engineer to make sure that each project is in precise accord with customer specifications. Available methods include:

  • Shielded Metal Arc Welding
  • Gas Tungsten Arc Welding
  • Gas Metal Arc Welding
  • Pulsed Gas Metal Arc Welding

All long, large, or complex parts are welded on our leading-edge Demmeler Bluco fabrication tables, which enable greater precision in the final result.

Rolling

With metal rolling, the stock is passed through rolls to uniformly flatten it out. Our Italian metal rolling machines consistently deliver precise results when used for metal rolling, sheet metal rolling, and structural rolling. We can handle workpieces up to 10 feet wide, and have over 20 years’ experience in producing:

  • Cylinders and cylinder segments
  • Concentric and eccentric cones
  • Helixes
  • Curved parts
