Precision Roll Grinding

Over time, the surface of rolls will wear down, causing performance and quality issues. Precision roll grinding works to reestablish the proper surface finish and roll profile.

Precision Roll Grinding

What is grinding?

Precision Roll Grinding refers to the process of removing material and surface generation to shape and finish components made of metals and other materials. The surface finish achieved with grinding is ten times better than with traditional turning or milling techniques. Rolls are often ground to meet specified total indicated runout (TIR) tolerances.

Why is precision roll grinding important?

Imagine driving a car with an oddly shaped tire. You notice vibration and instability, right? That same concept applies to rolls – a roll with imperfections will have a profound effect on performance. Based on the type of roll, it’s crucial that rolls are ground to exact specifications. Grinding is necessary to bring rolls back to their proper shape and finish.

What rolls need precision grinding?

Rolls are widely-used in the production of materials such as steel, aluminum, brass, copper, textile and paper. Common roll materials include:

  • 52100 Hardened Steel
  • Brass
  • Chilled Cast Iron
  • Ceramic, Chrome
  • D2 Hardened Steel
  • Stainless Steel
  • Steel
  • Tungsten
  • Carbide
  • Rubber

What are standard roll grinding tolerances?

  • TIR: .001
  • Straightness: .001
  • Station Deviation: .001
  • Station-to-Station Dev.: .001
  • Concentricity: .001
  • Surface Finish: 16 – 32 Ra

Roll Grinding Process & Services

The roll grinding process typically begins with a detailed inspection. This allows the operator to inspect the crown, concentricity and roundness of the roll. Equipment condition data and measurements are collected before the grinding process begins.The type of grinding necessary to restore the original properties and qualities are determined based on actual operating conditions and specific job requirements of the roll. Once the grinding technique is determined, the roll and equipment are prepped for grinding.There are four common many forms of industrial roll grinding:

  • Cylindrical Grinding
  • Internal Grinding
  • Centerless Grinding
  • Surface Grinding

Proper grinding will effectively remove oxidation, surface imperfections, cuts, cracks and other blemishes. Once tolerances are met, and the desire surface is achieved, the grinding process is complete. At Fertilla Machine and Grinding, we specialize in rolls. From custom roll covers to full-scope testing and analysis, we offer comprehensive services to ensure rolls are running at their fullest potential. Our precision roll grinding capabilities are designed to meet exact specifications and the tightest tolerances.

Non-Destructive Testing

What Is Non-destructive Testing?

non destructive testing

The name says it all – it’s a variety of testing methods that are non-destructive to the part or component being tested. Non-destructive testing allows you to test, inspect and evaluate components for discontinuities without destroying the serviceability of the part. In other words, when the test is complete, the part can still be used as intended. It’s also referred to as NDT.

What makes non-destructive testing better than other testing methods?

In contrast to NDT, other tests are more destructive in nature and are typically performed on a small sample rather than the entire assembly. While these methods are handy for determining physical properties of a material, this approach typically results in limited accuracy compared to NDT.

Who should use non-destructive testing?
It’s believed that the Romans used the concept of non-destructive testing, but the first recorded form of NDT dates back to 1868 when an Englishman used the magnetic properties of a compass to find cracks in the barrels of guns – other forms quickly evolved.

Today, modern forms of non-destructive testing are used in a wide-range of industries. Manufacturing and fabrication industries use forms of NDT to ensure product quality, improve manufacturing processes and minimize production costs. You might not realize it, but chances are, you’ve been a test subject for non-destructive testing. If you’ve ever had an x-ray or CT scan – then you’ve been a test subject! Medical professionals use NDT to diagnose – most common forms include film radiography, computed radiography (CR), computed tomography (CT) and digital radiography.

Non-destructive Testing Methods
There are several variations, the six most popular are:

  • Magnetic Particle Testing (MT)
  • Liquid Penetrant Testing (PT)
  • Radiographic Testing (RT)
  • Ultrasonic Testing (UT)
  • Electromagnetic Testing (ET)
  • Visual Testing (VT)

Fertilla Machine and Grinding offers non-destructive testing with unparalleled accuracy. These methods provide insight regarding the condition of their equipment and allows customers to make informed decisions based on the findings. NDT is a valuable technique that saves customers time and money. We accept nothing less than 100 percent accuracy, and we stand behind our services.

What is Polyurethane?

What is Polyurethane?Chances are, you’ve heard of polyurethane, but the question is, do you know why it’s the polymer of choice for numerous applications? What is polyurethane exactly? For starters, it’s a safe, environmentally friendly polymer known for its versatility in applications. This versatile polymer that exists in many forms, and can be adapted based on the application.

Invented in the 1940s, polyurethane has been used in virtually every industry because of its resilience, flexibility and durability. What forms of polyurethane are available? Basically every form imaginable from liquid to solid. There are four commonly used forms, including elastomers, coatings, foams and cross-linked foams.

Each form of polyurethane brings its own advantages and limitations.

  • Elastomers are used in everything from apparel to automotive parts and are known for their ability to stretch without losing their original shape and their shock absorbing qualities.
  • Coatings are used on surfaces from automobiles to industrial equipment and is known for protecting against corrosion, abrasion and chemicals.
  • Foams and cross-linking foams represent the largest market for this popular polymer. Foams are known for their strength and flexibility and are widely-used in numerous applications ranging from furniture manufacturing to commercial roofing.

A few examples of polyurethane applications include cushioning materials, shoe soles, surface coatings, building insulation, and it’s even used in healthcare to manufacture artificial heart valves. Industries are continuously adapting the composition to meet their needs. Additives such as fillers and catalysts can transform polyurethane to create a proprietary blend tailored the specific application or surface.

The origin of polyurethane dates back to World War II. Originally developed as a replacement for rubber, the adaptability of this material quickly spurred ideas for numerous applications. By the end of World War II, industrial applications skyrocketed and multiple forms were developed. Today, polyurethanes can be found everywhere from household to commercial uses. It’s in appliances, beds, cars, clothing, footwear, furniture and so much more.

The superior properties and versatility make it the polymer of choice for Fertilla roll covers. The surface quality of rolls is critical to quality. High performance polyurethane roll covers offer unparalleled abrasion resistance, hardness stability and durable bonding capabilities. This combination of properties make polyurethane the preferred cover for rolls.
