A high torque Siemens 18.5 kW (25 HP) spindle motor is employed on the BDL-1250/9D 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), as well as execute tapping or countersinking operations.

Continuous production can be stifled when frequent tool change is required. The BDL-1250/9D from Peddinghaus Corporation comes standard with a three spindle drilling unit in each drilling axis; eliminating the need to change tooling in programs with up to three hole diameters. Each of these powerful spindles are designed with Carbide Drilling in mind, and allow for the fastest drilling times on the market today.

What makes carbide tooling such a powerful production advancement? High speed drilling of up to 1800 RPM and feed rates of nearly 686 mmpm (27 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.

Peddinghaus provides maximum tool life by providing:

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

Peddinghaus users experience average tool life of 1,000-1,500 holes per insert, maximizing return on investment (ROI).

Don’t guess at drilling operations; finish every hole in a profile as quickly as possible using the Peddinghaus Smart Spindle approach. Not all material is perfect; flanges can be ‘toed in‘, ’toed out‘ or simply rolled at a varied thickness, this is the nature of structural steel. Before drilling, data is collected to distinguish all dimensions involved, and Smart Spindle takes place.

SMART SPINDLE DRILLING SEQUENCE:

1. Rapid Approach
2. Tool probes against material if length is not already established
3. The tool then retracts, spins in open air, and samples ’air drilling’ torque
4. Machine enters drilling feeds/speeds and begins hole creation. 90% through theoretical thickness of material (thickness material is supposed to be) the drill begins to monitor spindle torque again
5. Upon breakthrough of material, the machine senses a drop in torque similar to the ’air drilling’ reading
6. Tool is rapidly retracted and advances to the next hole in a pattern

Superior clamping is key to carbide tool life, and a higher Return on Investment (ROI). Proper clamping for carbide drilling requires maximum roller support, superior surface area contact, and innovative methods to ensure a rigid work piece.

The industry leading clamping system of the BDL-1250/9D maintains the following:

• A Z-Tower braking system that locks horizontal clamping in place (resistant to up to 9,072 kg (20,000 lbs) of force
• Comprehensive 4-point vertical clamping system
• Robust support, and clamping rollers on all surfaces of a profile
• Superior web clamping system that holds the web rigid on a wide array of profiles
• A unique underside support mechanism that prevents web deflection on wider profiles

Eliminate maintenance and overhead costs associated with water mixtures and flood coolants. The Peddinghaus BDL-1250/9D 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 drill lubrication methods:

• Eliminate the need to clean parts before painting, welding, or other processes
• 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

Punching has traditionally been recognized as an efficient and inexpensive form of hole creation. This method allows you to create slots, squares, and round holes in seconds with minimal mess, or maintenance.

Although punching is fast and affordable, it also creates small stress fractures within the material, which in some applications is unacceptable. Applications such as bridge work, or specialty industrial jobs, engineers and regulating personnel do not accept punched or thermally generated (plasma or oxy cut) holes.

Beyond engineering specifications, punching is limited to a maximum of 32 mm (1-1/4") thick material and a 1:1 material thickness to hole diameter ratio. This paired with the hardening of today's recycled materials proves challenging to traditional punching technology.

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 BDL-1250/9D using the continuous linear feedback of the spindle, and Siemens precision spindle motors. Through complete motion control the BDL-1250/9D can outperform and outlast drill lines of the past in these modern applications.

The Peddinghaus BDL-1250/9D comes with the industry leading CNC control panel from Siemens. This powerful multi-axis control panel offers the flexibility of a Windows® interface, while maintaining the robust build and quality of a shop hardened CNC control. The unmatched global access to spare parts, service, and industry leading warranty prove Siemens to be the ultimate electronics provider in today's machine tool market.

The 18.5 kW / 25 HP Siemens Spindle motor of the BDL-1250/9D provides the precision feedback, and raw power required in today's fast paced world of plate fabrication. Old fashioned "stepper" motors or "frequency" motors do not provide the feedback to maintain optimal carbide tool life. The data can include real-time RPM’s, drill torque, and tool rotational position.

4-Axis carbide scribing is available on the BDL-1250/9D drill line. Optional marking tools are stored within each of the drilling axes and selected upon program command. This combined with an optional underside marking system provides the ability to mark on the top/bottom flange of a profile as well as the top/bottom of a web. Multiple marking depths are available for desired visibility after coatings processes (adjustable marking depth of 1.5 mm - 3.2 mm (1/16" - 1/8")).

Carbide Scribing is ideal for:

• Marking part numbers - visible after painting, galvanizing, or other coating processes
• Designating weld locations
• Providing contour marks for manual cutouts

If elaborate layout information is unnecessary for operations, pop-marking can be easily applied. Offering both speed and economy, this layout marking solution rotates the drill tool in the spindle and gently touches material. This leaves a small 'dimple' that is perfectly visible to layout and fit-up personnel as they perform post production processes.

For maximum part numbering efficiency, an optional SignoMat part stamping system can be installed in tandem with the drilling machine. The hard stamping option will hold up to 36 characters or numbers, and will stamp characters at a rate of one character per second. Part numbers are stamped to a depth of 1 mm (1/32") and at a height of 12 mm (1/2").

BIM software programs (such as SDS/2, Tekla Structures, Graitec, and more,) are capable of creating part programs for use within Raptor by exporting data into a common file standard - DSTV. DSTV files are capable of being imported into the Raptor software platform for editing or CNC file creation purposes.

For fabricators who desire a more precise, data rich import, a direct Tekla API Module is available for optimized file conversions. Users of Tekla Structures have the option of importing geometry directly into Raptor with no intermediary file conversions. This direct transfer sources the original design of the structure and allows for automatic generation of scribe data.

The core of Raptor is the 3D Module. If part data has been imported into Raptor, the 3D Module works as an inspection tool and is capable of modifying imported information. If part files need to be created, the intuitive design and user friendly interface of the 3D Module allows for powerful programming options.

The Peddimat Legacy Export Module provides users the opportunity to create Peddimat files using Raptor. This export option allows users to develop part programs for operation on legacy machines that do not have an available Raptor post processor, or do not have an active license of Raptor present at the control.
