Frame Design

The box frame methodology used in the design of the base frame and gantry is constructed using all steel components that are cut, formed and welded by skilled craftsman in an industry-accepted vibratory process to insure consistency and reliability. All mating and reference surfaces are precision-machined by machinery designed to hold very high tolerances in order to guarantee that each system is capable of handling the quoted accuracy

Table Design

The standard system is available in 60- or 80-inch (1.5 or 2.0m) widths and in lengths up to 240 inches (6.1m). The table is available in either the slat style or the metal cutting option.

Slat Style• - The standard table top is a slat style cut bed with slats that are 1” (25.4mm) tall, 4pt steel rule on 4” (101.6mm) centers. Each slat has a radius on the edge to minimize flashback. The slat material provides a rigid base to hold such sacrifice materials as acrylic egg crate material.

Metal Cutting Option• - Optional metal cutting process slats are available with the capacitive cutting head option. This table design is set up to reduce flashback, facilitate the acrylic egg crate material, and provide a minimal point source of contact for metal cutting. The CNC files are made available upon request to allow the customer to fabricate replacement slats as needed.

Helical Rack and Pinion

The high speed helical rack and pinion system used on the 2000 Series Laser system offers many advantages.

Quieter Run• - Helical rack and pinions run much quieter than straight rack and pinions, especially at high speeds. Due to the angular cut in the helical rack and pinion setup, there are thrust loads on the gear shaft. This action requires thrust bearings to absorb the load and maintain gear alignment. The Alpha gearboxes that MultiCam already uses are designed to handle this load, and the new design of the 2000 Series Laser systems allows for exceptional perpendicularity and gear alignment. Faster Acceleration and Accuracy• – A greater number of engaged teeth allows the helical rack to easily achieve faster acceleration and accuracy than the straight rack. Distributing the load over several teeth also reduces wear and increases the life of the rack and pinion system. High-Speed Rapid Traverse Moves• – Helical rack and pinions allow for high-speed rapid traverse moves which customers can see and appreciate.

Linear Bearings/Rails

The X- and Y-axes use the 25mm linear ball bearing profile rails with stainless steel strip covers, while the Z-axis uses 15mm linear ball bearing profile rails. Features include:

High rigidity and load capacities in all load directions• Lowest possible noise level and best running characteristics• High torque load capacity• 30,400 Nm or 22,421 lb-ft dynamic capacity per pack•

Safety Controls

MultiCam uses safety controls on all systems, but the safety controls incorporated with the 2000 Series Laser show that MultiCam’s commitment to safety is exemplary in the industry.

The Center for Devices and Radiological Health (CDRH), part of the FDA, requires that all manufacturers • of laser systems in the US follow the product regulation 21 CFR 1040.10. (Laser manufacturers in Europe may self-certify to various product standards.) MultiCam is in compliance with this regulation and has been issued an accession number.All power controls are easily accessible to the operator at the front of the system and are keyed per the • CDRH regulations.Each system contains a mechanical shutter to ensure that the laser beam can be shut off when the need • arises.The light stack located on the top of the control cabinet contains three colored lights to indicate the status of • the machine at a glance: green = no laser output, red = laser output, yellow = maintenance mode. The light stack is located in clear view of all personnel during operation.All doors that could expose the operator or other personnel to any kind of laser radiation are interlocked. If • the interlocked door is opened, then the system will stop motion, close the mechanical shutter and indicate on the keypad that further instruction is needed from the operator.The Emergency Stop (E-stop) can quickly disable the laser power source and motion from the keypad as • well as other optional locations per customer request. Operators can reset the system back to the stopping point using the handheld controller.

In addition to the standard safety controls used on MultiCam’s 2000 Series Laser, there is optional equipment available for increased safety.

Safety mats – The area around the laser system can be fitted with safety mats to provide a safe area for • operators to enter when needing to stop motion and close the mechanical shutter. The safety mats act like an additional E-stop by requiring the operator to reset the system back to the stopping point using the handheld controller.Light curtain – The area around the laser system can be fitted with a one-, two- or three-sided light curtain • to provide a barrier that will stop motion and close the mechanical shutter. The light curtain acts like an additional E-stop by requiring the operator to reset the system back to the stopping point using the handheld controller.Laser safety eye wear – Operators and other personnel are encouraged to wear laser safety eye wear that • will provide additional protection for the eyes during laser operation.


12

Materials

MultiCam’s 2000 Series Laser can be used for many applications on many different types of materials, both natural and man-made. As with all laser applications, operators should consult the MSDS sheet for any material to be processed and pay close attention to the information regarding smoke or fumes produced when the material is heated and burned. The following materials are the most common for laser cutting.

Acrylics• – All cast and extruded acrylics can be processed with amazing results. The cut edge is left with a fire-polished finish, reducing the need for a post-process after machining.Woods and wood products• – The laser cutting on wood and wood products leaves a charred cut edge but a very small kerf width, which can provide operators a limitless supply of possibilities.Metals• – The maximum power laser offered by MultiCam can cut carbon steel up to 5/16” (7.9mm) and stainless steel up to 5/32” (4.0mm). Unlike the high kilowatt systems, the sealed tube design of the CO2 laser maintains a very low daily cost of operation.Marble/Granite• – The 2000 Series Laser cannot cut through but can imprint amazing quality images on the surfaces of marble and granite.Polycarbonate• – Thinner polycarbonate materials (e.g., Lexan) at 0.04” (1.0mm) can be laser cut with a dark brown to black cut edge.


13

Laser Processes

The laser is used for cutting, engraving and rastering material. Each process is described below.

Cutting• – Laser cutting is typically used in the production line and for industrial manufacturing applications such as cutting flat-sheet, structural and piping materials. Laser cutting works by using a computer to direct the output of a high power laser at the material to be cut. The material then melts, burns, vaporizes away or is blown away by a jet of gas, leaving an edge with a high quality surface finish.

Engraving• – Laser engraving is a very technical and complex technique whereby a computer drives the movements of the laser head to engrave or mark an object at a high rate. (Other systems use tool bits to contact the engraving surface, and those bits wear down and need to be replaced regularly.) Materials like polymer and novel metal alloys are specially designed for laser engraving, but marking can be a preferable alternative when the customer does not want to physically alter the surface of the material. Laser engraving machines can mark materials using such techniques as printing, hot-branding and laser bonding, which would normally have been done by other processes.

Rastering• – Laser rastering imprints an image on the material surface with the depth primarily controlled by the motion speed and the laser power. This image can be in picture file formats such as BMP, JPG, TIFF or GIF. The rastered image can be very eye-catching, especially in 3D, when processed in materials such as acrylic, wood, marble or other coated materials. Even materials that are commonly unable to be processed by cutting or engraving can be plated or coated with a special cover to help with the rastering process.
