A high torque Siemens 36 kW (48 HP) spindle motor is employed on the HSFDB to endure the most rugged drilling applications. This spindle specific motor utilizes an array of feedback that allows it to compensate for hard or soft spots in material (maintaining proper chip load), perform tapping or countersinking, and execute face milling, or oversized drilling.

With a machine as versatile as the HSFDB, a robust method of tool change is required to maintain ultimate efficiency. The unique tool changer design of the HSFDB accompanies the spindle throughout its entire range of motion. This ensures that no time is wasted when a new tool must be retrieved. Each drilling unit is immediately available as needed.

What makes carbide tooling such a powerful cost cutting instrument? High speed drilling of up to 2250 RPM and feed rates of nearly 760 mmpm (30 IPM). Carbide tooling provides opportunities where traditional high speed tooling falls short.

Although carbide tooling is easier to maintain due to its insert design, carbide itself is a fickle material. Carbide inserts of modern machine tools can exert incredible production power; however, simply dropping the tool on the floor can damage the carbide tip. How does Peddinghaus ensure maximum tool life with carbide tooling?

• A rigid workpiece
• A play free gearbox
• A precision feed

Peddinghaus users experience average tool life of 1,700-2,000 holes per insert, maximizing return on investment (ROI).

Why guess at your drilling operations? Finish every hole in a profile, in the fastest manner possible using the Peddinghaus Smart Spindle Approach. Before drilling, data is collected to distinguish all dimensions involved, and Smart Spindle takes place.

DATA COLLECTION:

• Tool length is either entered directly into the control, or automatically measured using a mechanical probe mechanism
• The non-datum and leading edge of the plate is located using state-of-the-art laser reference technology
• The thickness of the material is determined based on the resting roller location of the material drive and clamping mechanism
• The control understands where the underside and datum edge of the plate are located as these are fixed positions on the machine where the material rests

SMART SPINDLE DRILLING:

• The machine knows both tool length and material surface, this allows the spindle to approach the material rapidly to a safe distance, and then enters drilling feed rates
• Once the machine enters the drilling feed rates it knows the location of the end of the tool and the underside of the material. At the point in which the end of the tool travels past the of the profile the machine knows the hole must have been completed
• Upon hole completion, the drill tool is lifted a short distance above material and traverses immediately to the next hole in the program

11 metric tons (12 inch tons) of clamping pressure is applied to the entire width of material via drive roller and clamping bar. This ensures maximum rigidity at the drilling surface. Upon completion of a hole, tools are safe as all support beneath the material is away from the drilling location.

Dated designs commonly allow tooling to collide with slats and other support mechanisms. In addition, these systems commonly only offer a single probe for material clamping - if any clamping is employed at all.

Not only does this out-dated method cause costly premature tool failure, but support slat maintenance adds an entirely new requirement to the daily workload.

Eliminate the maintenance and overhead costs associated with water mixtures and flood coolants. The Peddinghaus HSFDB utilizes a modern vegetable oil based Minimum Quantity Lubrication (MQL) system which applies lubrication directly to the cutting surface. This "nearly dry" method of drilling offers benefits that are profound compared to yesterday's flood coolant methods:

• Eliminate the need to clean parts before painting, welding, or other processes
• Minimize the cost to maintain a system that filters flood coolant/table water and cycles it continuously through the spindle and drilling system
• Eliminate the need to add mixture to water tables, preventing it from becoming stagnant
• Remove health risks associated with chemical laden or slippery work conditions
• Drilling lubricant becomes vapor; this vegetable oil based solution offers a safe alternative to chemical based water mixtures

Not only has punching long been known as an economic way to process plate, it also allows fabricators to create slots, squares, and round holes quickly with little mess or maintenance. Drilling machines are becoming more flexible with the ability to mill slots and face mill components.

Something to consider is whether punched holes are acceptable for the application. Punching creates stress fractures within material, which can be undesirable based on the specifications stated. Applications such as bridges or specialty industrial situations do not allow punched or thermally generated holes.

Punching is also limited to a maximum material thickness of 32 mm (1-1/4"); this paired with the hardening of today's recycled materials provide challenges to traditional punching technology.

In applications that require many holes to be drilled in plate exceeding 40 mm (1-9/16") in thickness, Peddinghaus recommends a specialized "Oversized Hole" drilling option to ensure maximum tool life. Extensive testing has found that the application of high volumes of air combined with Eco-Friendly Minimum Quantity Lubrication and precision lead screw feeds are capable of exceeding tool manufacturers' expectations for longevity. Recent tests have illustrated a common tool life of nearly 400 holes without the need to index or change a carbide insert when drilling 70 mm (2-3/4") holes in 75 mm (3") thick plate continuously.

Tapping and countersinking are becoming more common, not only throughout the structural world, but within the manufacturing sector as well. Thread tapping in applications where a bolt would be previously welded are expedited whilst countersinking allows for bolt heads to be tucked away in final assembly. These operations are achieved on the HSFDB using the continuous linear feedback of the spindle, and Siemens precision servo motors. Through complete motion control the HSFDB can outperform and outlast plate processors of the past in these modern applications.

Face Milling, Slot Milling, and Hole Milling, are all functions of the HSFDB plate processor. These processes are achieved using the powerful spindle motor, and robust construction of Peddinghaus plate machines.

Precision positioning and feedback paired with ultimate Roller Feed accuracy allow the HSFDB to deliver face milling finish that is second to none. Whether you require a pocket milled surface to hide components within an overall assembly, or simply need a flush flat face for your application, the HSFDB delivers.

If your workload requires slots that exceed punching capabilities, or calls for holes that are too large to drill but cannot be thermally generated the HSFDB has a solution for you. Slot milling and hole milling are standard components of the HSFDB. Simply drill a pilot hole or burn a shape, and mill remaining material to reach your final goal.

Modern plasma technology offers unparalleled speed and cut quality. Whether you desire the clean cut of the HPR260 plasma unit, or the high powered HPR400 for thicker materials and faster cut times, you will find both to be suitable solutions to your cutting needs.
