WHITNEY LASER CUTTING MACHINES

WHITNEY Laser cutting machines are built with reliability and economy in mind. These proven-tough

machines use the best mechanical components available to ensure precision and reliability

throughout their service life. This special combination of durability and cost efficiency provides

maximum value for steel processors.

PROVEN SYSTEM DESIGN

In worldwide production for over 20 years, this design boasts an installed base of over 4,000 units. The

X axis uses high precision rack and pinion drive and an extra-wide base to drive the cast aluminum

alloy gantry. The Y-axis uses a precision ground ball screw to drive the lightweight cutting head. This

combination of design elements provides optimum rigidity and thus excellent cutting accuracy.

FLEXIBLE SOLUTIONS

Every customer has different needs based on their internal processes. We strive to meet our customers’

expectations and needs by giving them a choice of Cutting Speed, Laser Power, and Table Size.

For customers who want to automate their production, we provide material handling systems tailored

to meet specific automation needs. We also offer CO2 laser resonators for those customers who prefer them.

CUSTOMER BENEFITS

• Reliable processing of highly reflective materials such as aluminum, copper, brass and stainless steels.

• Loading small blank sizes is fast and easy with our unique cantilever design and front-access sliding doors.

• Fast controlled pierces using Whitney Rapid-Pierce Technology.

• Short learning curve due to the simplicity of design.

NEXT GENERATION LASER CUTTING – FIBER LASER

The brightness and smaller focus diameter created by a fiber laser

provides higher energy density and longer focal length which makes

the cutting process more stable. As a result, fiber laser beams can

process a wider range of material types, including highly

reflective sheets such as aluminum, copper, brass, and specialty

steels. Cutting with nitrogen provides a smooth edge without

oxidation at all laser power levels.

Fiber laser technology provides increased cutting speeds, the

ability to cut a wide-variety of material types and reduced

operational costs.

Reliability and energy savings of the fiber laser source result from

its simple design. The small number of solid-state components

reduces the risk of failure to an absolute minimum. The result is low

operating costs and minimized maintenance requirements when

compared to CO2 designs.

The laser source is designed for at least 100,000 working hours

and tested for 2,000 hours prior to final assembly. During this

period, neither maintenance nor replacement of laser operating

elements should be necessary.

AVAILABLE LASER SOURCES AND MAXIMUM MATERIAL THICKNESS.

SIMPLIFIED BEAM GUIDANCE

The laser beam is guided by a fiber optic cable which delivers energy from the laser source to the cutting

head without any interference and power loss. The fiber optic cable eliminates mirrors that are required

for beam guidance with CO2 laser technology. This system has no maintenance items such as

mirrors, gases and bellows, resulting in reduced operating costs.

CUTTING TABLE ACCESS

Front and side sliding enclosure doors provide convenient access to the process area for cutting head service,

loading small sheets and unloading cut parts.

ADVANCED CUTTING HEADS

Whitney laser cutting machines are available with several optional cutting heads which include manual and

automatic focus along with a fully automated focal length and beam diameter. Automatic focusing systems

are recommended for applications where a variety of different materials and/or thicknesses are encountered.

FEATURES

The aluminum alloy cantilevergantry is cast for reduced weightwhile providing excellent rigidity.

The cutting table is independent ofthe machine base which eliminatesthe potential for inaccuracy based onthe cutting process.

Zoned dust collection is standardon all models.

Whitney machines are designed withthe installer, operator and servicetechnician in mind. All machine areasare easily accessible.

Whitney systems utilize many common components available on a worldwide basis. However, we maintain a well-stocked parts warehouse at our Rockford, IL, USA facility.

The electric (no hydraulics), automatic,dual pallet shuttle is standardequipment and allows cut part andskeleton unloading while the lasercontinues cutting.

FIBER LASER CUTTING OF HEAVY PLATE

In the 1990s, Whitney pioneered the development of heavy plate cutting with CO2 lasers. Whitney now leads the way in developing fiber laser cutting of heavy plate. We have developed production cutting parameters for cutting thick carbon steel with cutting speeds and edge quality that rival CO2 laser cutting.

Our advanced, heavy plate cutting capability and our unique Rapid-Pierce Technology make Whitney laser cutting machines superior to all others for cutting plate steel.

WHITNEY’S RAPID-PIERCE TECHNOLOGY

Whitney has adapted its unique Rapid-Pierce technology to our fiber laser cutting systems. This unique combination of optics and parameter control during the piercing cycle generates extremely fast pierce times in heavy material with small pierce holes and low heat input to the work piece.

The benefits to the end customer are:

Fast Cycle Times—Many laser cutting machine manufacturers still use slow pulse pierce technology. Whitney’s Rapid-Pierce technology pierces 1” (25mm) thick mild steel in less than one second, while pulse piercing may take 15 seconds or more. This translates to savings of minutes (not seconds) per part when parts have multiple internal holesand cutouts.

Better Cut Quality—By keeping heat input low, small holes can be successively pierced and cut cleanly. Other piercing technologies such as blast piercing or pulse piercing transmit more heat into the work piece, creating dross and stuck slugs. With Rapid-Pierce, operators no longer need to hammer out small cutouts in thick steel.

Easier Programming—When using other piercing technologies (blast or pulse piercing),customers often resort to programming all of the pierces in a nest of parts first beforecutting the features. This allows each localized pierce area to cool before returning to that same area to cut the feature. This process increases the nest cycle time.The Rapid-Pierce process imparts minimal energy to the workpiece so it can be cut immediately after piercing without cut quality degradation.

LOW HEAT INPUTThis ¾” sample was made by making 10 consecutive

pierces using Whitney’s Rapid-Pierce technology,

and then immediately cutting the perimeter.
