Effect grinding - Import export

The choice of the right serrated grinding wheel for grinding knives, scissors, tweezers, pliers, surgical instruments, etc. with the most suitable teeth and the highest quality standards must be determined on a customer-specific basis depending on the intended use. The base body of the serrated grinding wheel is made of aluminum. A coating is applied to the aluminum body, into which the teeth are then inserted depending on the profile shape according to the intended use. With our many years of experience, we would be happy to advise you by telephone or on site regarding a high-quality and cost-effective design of a serrated grinding wheel for your process.

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.

The VEN BRUSH system technology is based on high pressure at low speed. Special hold-down brushes with wide support brushes or narrow support brushes for processing profiled workpieces, ensure the required pressure. For the pretreatment of workpieces of varying shapes or extremely fluctuating sizes, maximum perfection and flexibility are provided by the motor-driven height adjustment of each individual unit as well as by the infinite rotational speed setting. The high-performance vacuum transport belt ensures reliable transport and holds both small as well as large format workpieces in place. A Molton roller is built in to ensure constant cleaning of the conveyor belt. Unit diversity results in a wide performance spectrum and generates a high economic effect. The basis version of VEN BRUSH allows a selection of 2 unit positions to up to 5 unit positions. To be prepared for possibly changing requirements in your production process, you can also select the next larger variant and equip the free unit position as required at a later date. System examples for possible operating widths from 600 to 3,500 and operating lengths from 2,000 to 5,500 mm. Depending on your production requirements, you can individually select from: Short change times and high operating comfort are possible thanks to the quick-exchange brush system using a push-in system together with a coupling. The optional infinite angle setting of the round brushes permits impeccable edge processing. The use of the structured brush unit is intended for special surface processing. This brush is used to structurise furniture parts, hardwood and softwood, flooring boards or to provide an antique look of up to 1 mm deep at a throughfeed speed of 10 m/min. Where required, the VEN BRUSH can be extended by a dust removal system with rotating blow nozzles and ionisation system. Following a brushing or sanding/grinding effect, this complementary function ensures optimum workpiece cleanliness to meet high requirements. As an individual solution, VEN BRUSH convinces as a station in a Venjakob machine line or when integrated in an existing machine line. As such, control system configuration takes all interfaces into account, through to higher ranking control and monitoring. The high-performance system technology can be easily operated directly using a control panel or a touch panel.

This tree stump grinder is our own in house product. It can be attached to most excavators between 1.0t and 3t weight with our custom made bracket and will allow the user to grind tree stumps effectively in almost any location. It is hydraulically driven from the excavator and requires little maintenance apart from replacement of cutting teeth when worn. It is supplied with everything needed to start work straight away. See our website or contact me for further details. We are interested to find re sellers for this product in some European countries.
