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.

The rotary table combination RT3A100 consists of two directly driven rotary tables of the RT3A100 series. The B-axis has a swivelling range from approx. -10° to +110°; the C-axis can be rotated infinitely. The unit is driven by two integrated 3-phase synchronous motors. The drive guarantees highest dynamics and precision. An innovative clamping unit integrated in the housing guarantees high holding forces when the drives are switched off without position changes on the axes. By means of compressed are impact, the holding torque can be increased from 15Nm to 20Nm for special applications. The complete system is supplied as ready-to-connect unit.

We offer our customers the leasing of our test bays for testing your machines and systems.The above-mentioned machines can also be coupled in sets of three so that even higher outputs are possible. At LDW we also have several DC machines with other speed ranges and lower outputs. We also have three-phase load machines with speed ranges from 750 to 3,000 1/min at an output range of 1,400 to 3,000 kW. Our largest measurement shaft has a torque of 5,000 Nm (accuracy class <1%). We usually verify the torque via a DC-machine. We have several DC machines with speed ranges of 100 to 6000 1/min in the test bay (depending on requirements) at an output range from 100 to 1,500 kWThe maximum torque of our largest measuring shaft is 5,000 Nm (accuracy class <1%), we usually verify the torque via a DC-machine. Depending on the specific needs we have several DC-machines with speed ranges from 100 to 6,000 rpm and outputs from 100 to 1,500 kW.

It is increasingly important to make provisions and to keep one’s own machines in good condition. This reduces downtimes and prevents a decline in production. Our seamless diagnostics helps to ensure that machines run fault-free and enables advance planning of maintenance or repair work. The experts from LDW bring their equipment to the customer to inspect the machine on site. From partial discharge measurement through to vibration measurement – we clearly identify what technical state a machine is in. This allows downtimes to be planned ahead and ensures the efficient repair of the respective component.Diagnostics at our works in Bremen is even more effective, because we can directly consult an expert from the mechanical construction, electrical calculation or the R&D department for an assessment if necessary. The customers are provided with a comprehensive protocol after the measurements have been carried out. We then recommend the next steps for a repair or continued operation.

Machines are only as reliably available as their spare and wear parts. We therefore offer a comprehensive range of all important services. Thanks to our extensive archive, we are in a position to offer spare parts and services even for older machines from LDW, AEG and Garbe-Lahmeyer. We only need the serial number of the old motor or generator to provide or manufacture the corresponding spare parts. We are happy to assist with any question you have concerning our spare parts services, tender preparation or on-time procurement and delivery. The quality specifications we have for new parts of course also apply to our spare partsDespite the high quality of our products, the service life of some components is essentially determined by operating and environmental conditions. To avoid costly downtimes it is essential to implement preventative measures. Stocking spare parts is one example of such a sensible measure.

The repair works are located at our site in Bremen. Through the utilisation of all the resources of our manufacturing operations our customers enjoy all the benefits of repairs, maintenance and reconditioning in accordance with the DIN IEC60034-23 standard. For work on explosion-proof machines we can provide all the certificates required for order fulfilment in full compliance with legal provisions. LDW has a certified expert and the legally binding permits ATEX, PTB KTE etc. required for a professional execution. All AEG documents from around 100 years of electrical engineering are available in their entirety within our company. This enables us to carry out repairs, supply spare parts or complete machines that are electrically and mechanically interchangeable. As part of this process we upgrade these procedures in step with the latest technological developments. The energy balance is thereby significantly improved on a regular basis.

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.
