Mechanically, the M3 mod. 400/U features a reliable motor that guarantees adjustable rotation speed based on the needs of the material being sharpened. The motor can generate rotation speeds between 1500 and 3000 rpm, ideal for sharpening both steel tools and harder materials like widia. The adjustable vice allows for precise sharpening at different angles, minimizing tool wear and increasing their lifespan.

M3 mod. 400/U sharpener is intuitive to use . After securing the tool to be sharpened in the vice, adjust the desired angle using the controls on the adjustable vice. Once the sharpening angle is set, turn on the machine and begin the sharpening process. Thanks to the adjustable rotation speed and the available grinding wheels, precise and uniform sharpening is possible.

To optimize sharpening parameters, it's important to consider the hardness of the material. For example, for steel tools, a rotation speed of around 2000 rpm is recommended, while for widia, the speed could be reduced to avoid overheating.

The M3 mod. 400/U comes with a range of grinding wheels specifically designed for different materials. Grinding wheels for steel tools and diamond wheels for carbide tools are available, ensuring maximum flexibility of use. Additionally, accessories such as adapters for sharpening cutters of various shapes and sizes can be combined.

The M3 mod. 400/U is designed to sharpen a wide range of tools made of different materials. It can effectively work with HSS steel tools, traditional tool steels, and hard materials such as widia (tungsten carbide). The availability of specific wheels for each material ensures a consistently high-quality finish.

To ensure optimal operation and extend the life of your machine, it's important to perform regular maintenance. This includes periodically cleaning the work surfaces and grinding wheels, lubricating moving parts, and checking the condition of the grinding wheels to prevent inaccurate sharpening. If your machine isn't CE certified, you can make it compliant by adding grinding wheel guards and emergency stop devices.

Safety regulations include the use of protective eyewear for the operator, cut-resistant gloves, and extraction systems to reduce dust generated during sharpening. If the machine does not comply with the latest CE regulations, it is advisable to upgrade it by installing additional guards and safety switches.

Evaluating the M3 mod. 400/U as a good used item requires attention to detail. It's important to check the condition of the adjustable vice, verify that its movements are smooth, and that the motor operates without abnormal vibrations. Another indicator of quality is the condition of the grinding wheels and guides, which must be in good condition to ensure precision work.

The M3 mod. 400/U is ideal for machine shops, tool companies, and workshops specializing in sharpening cutting tools. Buying a used machine like the M3 mod. 400/U offers significant economic advantages: you can get a high-quality machine at a lower price than a new model, with the added benefit of being able to test its operation on a proven, reliable product.
