Services
Comprehensive Roll Manufacturing & Reconditioning Services
At Master Roll Manufacturing, we provide precision machining, roll reconditioning, and surface-critical finishing services for coil processors in the steel, aluminum, pulp & paper, and toll processing industries. From custom roll manufacturing to multi-stage repair and testing, every solution is built for performance, accuracy, and longevity.
Most services are performed at our Northwest Indiana facility, with CNC and manual machining, induction hardening, and expert technicians handling your project from start to finish. For services that exceed our in-house capabilities, we have developed long-term relationships with trusted partners to ensure that together we can provide parts that meet our stringent quality standards.
Types of Services We Offer
Custom Manufacturing
We provide full-spectrum precision machining, including turning, milling, and drilling — built to meet the specs of OEM rolls, mandrels, arbors, customer drawing and more. Whether you’re building new or modifying existing equipment, our team delivers consistent results from high-grade, certified steel.
Roll Reconditioning
Our roll repair and reconditioning services include inspection, journal repairs, welding, sweat fitting, and restoring surface finish across a set of rolls. We help extend the life of work rolls, intermediate rolls, back up rolls, backup bearings, feed rolls and pinch rolls, often reconditioning a roll up to five times with verified tolerances and surface finishes.
Precision Finishing & Testing
We offer expert services that ensure every roll meets tight production tolerances, achieves optimal performance, and stands up to demanding applications. From super finishing to straightening and certified inspections, we ensure total reliability and repeatability.
Our Full Service Capabilities
Master Roll is equipped to handle parts up to 210″ between centers and 36″ in diameter. Machines are outfitted with DROs and/or Arnold Gages for increased precision.
Turning
Manual and CNC turning capabilities allow us to meet the most demanding specifications using a wide range of materials. Our maximum capacity is 210″ in length and 36″ diameter — ideal for large industrial rollers, mandrels, and arbors.
Milling & Drilling
Using both CNC and manual mills, we produce keyways, splines, lock slots, and other custom geometries required for high-performance tooling or drive systems.
Grinding
We provide both centerless grinding (up to 3″ diameter and 210″ length) and cylindrical grinding (up to 22″ diameter and 16′ in length), producing ultra-smooth surfaces for steel rolls, shafts, and precision components.
Super Finishing (Microfinishing)
This advanced process improves both surface finish and part geometry, achieving 1-2Ra which is imperative to our customers who are required to process flawless sheet and plate material. It’s proven to extend roll and component life up to 4x, especially in heat transfer roll and calendar roll applications.
Reconditioning
We begin with an “as received” inspection to verify rework potential. Our reconditioning may include, journal repairs, straightening, drawing hardness back, weld-up and turn downs, sweat fitting un repairable journals, or simply refurbishing the surface finish.
Straightening
Hydraulic and manual straightening services for rolls up to 8.5″ in diameter and 210″ long. Ideal for correcting material distortion or prep for finishing.
Heat Treating (Induction Hardening)
We offer in-house induction hardening of steel rounds up to 6″ diameter and 14′ long, improving surface wear resistance for demanding industrial environments.
Inspection & Certification
We document every step of the process, from material certification to hardness testing, RA measurement, and TIR (Total Indicated Runout). Inspection reports are available upon request and align with OEM quality standards.
