Ohio Roll Grinding, Inc. is a privately owned company established in 1981 located in Louisville, Ohio. We offer a wide range of services including Roll Grinding, Knife Sharpening, Chrome Plating, Fabricating and Trucking.
Grinding wheels made of aluminum oxide grains of special composition may also provide advantages in profile grinding by retaining their size and shape longer, due to their freer cutting action. Silicon carbide of the regular type is used for grinding cast iron and nonferrous metals, and a special high purity type is used occasionally for the
If the roll is truly a straight taper most processes can be adjusted. The opposing roll, doctor blade or die can be adjusted accommodate the 0 .00025 radius change. Conversely, if there is a 0.0005 dip in the profile that is concentrated in a short span,it is much more difficult to adjust a straight opposing surface.
And Evaluation Mill Modernisation Roll Measurement Offline Cross-profile Vollmer produces the automatic roll measuring gauges for both bench-mounted machines where the roll is moved along the grinding wheel and for support machines where the grinding wheel is moved along the rotating roll. Vollmer supplies the systems for a broad spectrum

Any calendering system, with or without a FACTS, Inc. control systems will perform best with properly maintained calendering rolls.
The profile is selected so that the roll separating forces, which cause the rolls to bow apart in the center, are partially compensated for by grinding the center to a larger diameter.
The specific profile selected is based on the range of rubber compound hardness, type of center compensation such as cross-axis or roll bending, and roll width.

The EASY series CNC surface and profile grinder with its EASY to learn, EASY to program, shop floor language, is indeed an innovation for close-tolerance, repeatable, multi-purpose grinding. The EASY Series incorporates all the excellent features required for high precision grinding.
Grinding and Grooving Computer-controlled equipment and specialized tooling allow Pinnacle Roller to offer a full array of geometric crowning profiles, tapers, and grooving patterns. Shown below are some of the common grinding and grooving patterns that Pinnacle can handle.
Conditions. Many kinds of conventional grinding wheels, and in special cases super-hard grinding wheels, can be dressed with this dressing method. CD dressing continuous dressing is often used for dressing grinding wheels used to machine hardened work parts as well as super-alloy fine profiles. For all types of dressing applications, DR.

Browse Our Angle, Profile amp Ring Roller Machines. These machines are specifically designed for circular bending of metal profiles, angles, or rings, and can be operated either vertically or horizontally. The standard set of bending equipment is suitable for bending square, flat, angle, and shaped profiles.
The physical model of the roll grinding system measurements14 is illustrated in Figure 2. For the roll there are two types of sensors two laser sensors and two inductive displacement sensors all of these are on the sledge of the grindstone, moving horizontally along the roll during grinding.
For grinding of specific roll curves with a large variety of diameters, WaldrichSiegen has developed the B-axis. This patented concept ensures that the grinding wheel is always positioned vertically to the corresponding tangent of a curve. Thus, infeed marks are eliminated. The cast iron upper carriage of the ProfiGrind machines is designed for
You must periodically grind the calender rolls to establish the proper profile. Your selected crown profile is based onthe range of your rubber compound hardness, type of center compensation such as cross-axis or rollbending, and roll width.
Your calender rolls must be round and free of run-out at ambient temperature. Any run-out of theindividual calender rolls will be amplified as the high spots and low spots periodically match up betweenthe roll pairs. You can easily check this with dial indicators when the calender is running withoutrubber and with a smallnip gap between the pairing rolls.
The left side of could be used to denote the compound profile of work roll. Therefore, the compound profile of work roll for the above-mentioned normal rolling process is shown in Figure 2a. The compound profile between backup roll and work roll is in an asymmetric V style, while the distribution of interroll force is in an S
Surface amp Profile Grinding Machines For everything from forming dies and steering racks to turbine vanes and linear guideways, manufacturers must achieve fine surface finishes despite complex curvatures and high-precision part features.
The forces cause the work roll deflection including rolling force, interroll force, and work roll bending force, so work roll deflection at element could be expressed as 5, 6where is the work roll deflection influence function due to the combined bending and shear forces generated by rolling and interroll force at element is the work roll bending influence function due to the work roll bending force.
