Overview
The Prodevco PBD family can suit recurring structural-steel hole patterns when the selected configuration matches your member sizes, tooling, file workflow, and material handling. Compare specific machine configurations against the shop’s actual work—not the PBD family name alone.
- The PBD 13 has three drilling heads and sub-axis spindle positioning for simultaneous multi-face drilling, including holes that are not aligned; verify the quoted tool-changing arrangement and operation sequence for other supported operations.
- Published ranges differ: the PBD 7/PBS 700 tandem system lists sections from 5 × 2-1/2 to 28 × 16 inches and 1/2–1-1/4-inch drill bits; the PBD 13 lists 6 × 3 to 51 × 24 inches and 1/2–1-1/2-inch bits. Neither range guarantees compatibility with every profile, orientation, or handling setup.
- Test representative drawings and DSTV/NC1 files for feature interpretation and hole requirements. The AISC Code of Standard Practice does not specify hole or hole-pattern location tolerances, so check project drawings, specifications, and applicable connection requirements.
- The PBD 7 is documented with the PBS 700 tandem drill-and-band-saw system; PBD 13 can integrate with the PBS saw line. Confirm the quoted saw arrangement and review infeed, outfeed, staging, and downstream material movement.
The Prodevco PBD is a multi-spindle CNC beam-drilling family for structural profiles, suited to recurring multi-face hole patterns and related machining when member sizes and tooling match the selected configuration.
Where multi-spindle beam drilling fits
The PBD 13 uses three drilling heads and sub-axis spindle positioning to support simultaneous drilling on profile faces, including when holes are not aligned; the documented feature set also includes slot machining. For compatible part geometry, machining multiple faces in one setup can reduce the need for repeated repositioning. The benefit depends on the member and hole pattern, not simply on adding automation.
The PBD 13 also supports drilling, milling, tapping, countersinking, layout marking, and center-point marking. Those operations can suit recurring work that would otherwise require separate machining steps, but the buyer should verify the quoted tool-changing arrangement and operation sequence. The PBD 13 uses DSTV (.NC1) files, so representative files from the shop’s detailing workflow are useful for checking export, programming, and feature interpretation before selecting a configuration.
Compare the PBD 7 and PBD 13 envelopes
The documented PBD 7/PBS 700 tandem drill-and-band-saw system lists a section range from 5 × 2-1/2 inches to 28 × 16 inches and drill-bit capacity from 1/2 to 1-1/4 inches. The PBD 13 page lists a section range from 6 × 3 inches to 51 × 24 inches and drill-bit capacity from 1/2 to 1-1/2 inches. These are variant-specific published figures; the PBD family name alone does not identify the machine or options covered by a quote.
Compare the listed envelope with the actual member schedule, including profile shapes, cross-sections, lengths, weights, and common hole diameters. A published section range does not by itself confirm compatibility with every shape, orientation, tooling requirement, or handling arrangement. For Arizona structural fabricators, the useful question is which documented configuration suits the recurring work and can fit the shop’s material flow.
Check hole patterns and file flow
Review representative drawings or DSTV/NC1 files for hole locations across faces, slots, and any tapping, countersinking, milling, or marking. Confirm that the detailing export and any shop-side post-processing represent those features as intended. A spindle count alone does not establish that finished holes satisfy a particular project’s requirements.
AISC lists drilling among acceptable methods for making structural-steel bolt holes. Its fabrication-and-erection tolerances FAQ states that the AISC Code of Standard Practice does not specify a tolerance for hole or hole-pattern location. Compare hole type, size, pattern, and applicable tolerances with the project drawings, specifications, and governing connection requirements; verify the relevant bolting requirements where high-strength bolted joints apply.
Plan the line around material movement
The PBD 7 is documented with the PBS 700 in a tandem drill-and-band-saw system, while the PBD 13 can integrate with the PBS saw line. Those are distinct configuration paths, not evidence that a saw is included with every PBD. Decide whether the application calls for a drill line alone, the documented PBD 7/PBS 700 arrangement, or a PBD 13 saw-line integration.
Map the proposed configuration against infeed and outfeed space, clamping access, stock staging, crane or conveyor movement, and downstream operations. Bring actual member lengths and weights into that review: a cross-section that falls within a published range may still create a handling or layout constraint. Confirm the quoted feed, tooling, file, and saw arrangements before comparing the line with the current workflow.

I can help compare the PBD configurations and assess file flow, tooling, material movement, saw integration, installation, and support needs with Mac-Tech. Bring representative beam drawings or DSTV/NC1 files, profile sizes and member lengths and weights, recurring hole patterns and tool requirements, your production mix, and any material-handling constraints.
