Plate, Slab & Bar Milling Services
Not every material should be ground. For titanium and many specialty alloys, milling is the superior choice — and MSI Corporation has the equipment, the expertise, and the track record to prove it. Our planer mill capabilities handle the industry's most demanding jobs: pieces up to 50 tons, 10 feet wide, and 38 feet long, processed with precision and full material traceability from start to finish.
Heavy-Duty Planer Milling Capabilities
MSI operates a wide array of planer mills engineered for large-format, heavy-weight material processing. Whether your job requires aggressive stock removal, precision gauge reduction, or targeted defect elimination, our mills deliver consistent results across a broad range of materials and geometries.
Milling Capacity
Our planer mills accommodate some of the largest pieces in the industry:
- Width: Up to 10 feet
- Thickness: Up to 6 feet
- Length: Up to 38 feet
- Weight: Up to 50 tons
With 75-ton overhead hoists throughout our 80,000 square foot facility, we handle material that most milling operations simply cannot accommodate. If your piece is oversized, overweight, or has been turned away elsewhere, MSI is built for it.
Coolant-Assisted Milling
Thermal management is critical when milling titanium and specialty alloys. MSI's coolant-assisted milling process controls heat at the cutting interface, protecting the material's microstructure and mechanical properties throughout the operation. This approach also means our milling process does not promote crack development or expansion in alloys where grinding poses that risk — a clinically significant advantage for aerospace and defense applications where material integrity is non-negotiable.
Milling as a Proven Alternative to Grinding
MSI Corporation has been instrumental in establishing planer milling as a viable, often superior alternative to grinding for defect removal in titanium alloys. This isn't a marketing claim — it's a process we developed, refined, and proven across decades of production work with some of the most demanding customers in the aerospace and specialty metals industries.
Why Milling Outperforms Grinding for Titanium
Grinding generates significant heat at the workpiece surface. In titanium alloys, this heat can drive crack initiation and propagation, creating subsurface damage that isn't always visible but can compromise fatigue performance in critical applications. Coolant-assisted milling eliminates this risk by removing material mechanically at controlled temperatures, producing a clean, defect-free surface without the thermal stress profile associated with grinding.
For processors and end-users working with titanium plate, slab, or bar who have experienced surface cracking, unexpected rejects, or concerns about subsurface integrity following grinding operations, MSI's milling process offers a reliable, technically validated alternative.
Defect Removal and Gauge Reduction
MSI's milling services address two of the most common processing challenges in the specialty metals supply chain:
Defect Removal
Surface and near-surface defects — seams, laps, cracks, inclusions, and alpha case — can render otherwise usable material non-conforming. Our milling process removes these defects precisely and efficiently, recovering material value and restoring conformance without the risk of thermal damage associated with grinding-based defect removal.
Gauge Reduction
When material arrives oversize or requires thickness reduction to meet final specification, our planer mills deliver tight, repeatable gauge reduction across the full cross-section. We maintain dimensional control and surface quality throughout, ensuring your material arrives at the next processing step — or your customer — ready to use.
Turnings Recovery Program
Titanium and high-value specialty alloy turnings generated during milling operations represent significant recoverable material value. MSI's turnings recovery program ensures none of that value is lost. We collect, segregate by alloy grade, identify, and return all turnings to the customer for remelting — supporting your material cost recovery and sustainability objectives.
This capability is particularly valuable for aerospace-grade titanium where material traceability requirements extend to turnings and scrap, and where every pound of recoverable material has real dollar value.
Materials We Mill
Our planer mills process a wide range of metals and specialty alloys, including:
- Titanium alloys — commercially pure grades, Ti-6Al-4V, and other aerospace-grade alloys
- Stainless steel — all grades, plate and heavy slab
- High-nickel superalloys — Inconel, Hastelloy, Monel, and related materials
- Carbon and alloy steels — heavy plate and bar stock
- Specialty and exotic alloys — processed to your exact specification
Industries Served
MSI's milling services support processors, distributors, and manufacturers operating across industries where material quality, traceability, and processing expertise are critical:
- Aerospace and defense
- Power generation
- Oil and gas
- Medical device manufacturing
- Specialty metals distribution and processing
- Heavy industrial manufacturing
Why MSI for Plate, Slab, and Bar Milling?
Unmatched Capacity
50-ton pieces. 38-foot lengths. 10-foot widths. Very few facilities in North America can mill at this scale with the precision and material care that aerospace and industrial customers require. MSI can.
Technical Leadership in Titanium
MSI didn't just adopt milling for titanium — we helped prove it works. That depth of process knowledge translates into better outcomes: fewer rejects, more predictable results, and a processing partner who understands the material science behind every job.
Fully Integrated Processing
Milling is rarely the only operation your material needs. MSI's full-service facility means your material can move seamlessly from milling to precision grinding, saw cutting, heat treating, shot blasting, or NDT inspection — all under one roof, with one point of contact and full traceability throughout.
Complete Documentation and Traceability
Every milling job at MSI is supported by full material traceability, including certified mill test reports, dimensional inspection records, and turnings segregation documentation where applicable. Our Level II NDT inspectors and in-house testing capabilities ensure your material leaves our facility with the documentation your quality system requires.
