Black oxidation treatment is a commonly used chemical surface treatment method for metal parts, including steel, stainless steel, copper and brass. The principle of this process is to immerse the metal in a heated solution containing oxidized salt, so that the metal surface forms a black oxide film to achieve the purpose of rust and corrosion resistance. This oxide film is usually iron tetraoxide (Fe304), which not only improves the corrosion resistance of the metal, but also gives it a black appearance. This surface treatment is widely used in areas such as precision machining projects, automotive parts, tools and decorations, and the advantages of black oxide include better corrosion protection, reduced light reflection, dimensional stability and aesthetic appeal. In short, the black oxidation treatment is a versatile technology suitable for the improvement and protection of various metal parts.

In combination with most modern motion control systems our Roll Feeds feature a highly reliable production support with dynamic feeding performance of max 30 m/s² acceleration. For smaller crosssections we offer the HSseries Roll Feed model This dynamic and costeffective solution makes the upgrade from gripper feeds to the much more flexible roll feed technology affordable. from coil up to 2000 mm material width and up to 8 mm thickness max crosssection approx. 2000 x 5 mm Vmax approx. 80 200 m/min max cycles with pilot release approx. 100 220 SPM from plate or bar up to 20 mm material thickness

For the special requirements of your belt conveyor system, we manufacture for you idler pulleys, carrying idlers, throbbing drums, lift pulleys with or without internally located cone. With diameters up to max. 1,000 mm and lengths up to max. 4,500 mm, these are suitable for all types of belt conveyor system. All pulleys are turned cylindrically or spherically. The axle connections can be delivered in alternative designs with internal bearings, welded, with wedged connections or with clamping set shaft connections. Special designs such as stainless steel and/or friction linings (ceramic, rubber) and accessories (pedestal bearings) can be delivered upon request.

The carrying frame prevents belt misalignment and guarantees protection of the belt edges. As the carrying frames only function efficiently when the drum casing is clean, they are equipped and delivered with dirt repellent 60° shore soft rubber. Our carrying frames can be used with both normal and reversing conveyor belts. Mode of operation When the conveyor belt is running straight, the axle through the roller casing forms an angle of 90° to the direction of movement of the belt. When the belt drifts, the roller casing moves, due to the dead weight of the belt, so that a forward motion occurs which brings the belt back to its normal position. The roller casing returns to its normal position as soon as the corrective procedure is completed. The mechanics of the movement are rendered possible due to a complex ball joint in the centre of the roller as well as the position of the axle in relation to the conveyor belt being less than 90°.

The gauges from the VSL Series measure the form, diameter, roundness and eccentricity of the rolls during the grinding process with very high precision. Form, radial run-out and eccentricity are measures with a precision of ± 1 µm. If an interface is available, they communicate online with the controller of the roll grinding machine and thus enable even more cost-effective use of the grinding machine. With the appropriate configuration, they measure the height and lateral alignment of the roll in the grinding machine before grinding, often enabling the set-up time to be significantly reduced. 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 of roll diameters.
