The M3 sharpener mod. 380US with chuck is an excellent solution for those looking for a used machine, but in perfect working order. It is a versatile, robust model and highly appreciated for its ability to sharpen a wide range of cutting tools. Ideal for mechanical workshops, sharpening laboratories and industries that need to keep cutting tools always efficient, the M3 mod. 380US offers reliability and precision in every operation.
On a visual level, the M3 sharpener mod. 380US has a compact and well-balanced structure. The machine is built with a gray cast iron base, which guarantees solidity and reduces vibrations during work, thus improving the quality of sharpening. The central spindle is well protected and easily accessible for changing tools, making it easier for the operator in replacement and adjustment operations.
The overall dimensions of the machine may vary slightly depending on the accessories fitted, but in general they are around 1000 mm in length, 800 mm in width and 1200 mm in height. The total weight is around 600 kg, making the M3 mod. 380US stable during use, even for intensive operations.
The M3 mod. 380US is equipped with a powerful motor that guarantees a constant rotation speed, ideal for sharpening steel tools and harder materials such as widia. The three-phase motor provides a power of approximately 2.2 kW, with adjustable speed between 1500 and 3000 rpm, depending on the type of tool to be sharpened and the material being processed.
Thanks to the chuck, the machine is able to grip and process tools with variable diameters, allowing high precision in sharpening operations. The M3 sharpener mod. The 380US also features a swiveling head that allows the operator to adjust the sharpening angle, adapting to a wide range of tool geometries.
The use of the M3 mod. 380US is simple and intuitive. Once the tool is fixed in the chuck, the sharpening angle is adjusted according to the type of cut desired. After setting the angle, you select the rotation speed best suited to the tool material (for example, a lower speed for widia tools and a higher speed for high-speed steel).
Thanks to the fine adjustment of the head and the possibility of mounting different grinding wheels, the operator can obtain precise sharpening with a uniform finish. The machine also has a cooling system to prevent the tools from overheating during sharpening.
For the M3 sharpener mod. 380US , numerous accessories are available that expand its versatility. Among these we find grinding wheels for sharpening steel and widia tools, additional supports for cutters and drills and measuring instruments to ensure precision sharpening. The machine is also compatible with diamond wheels, ideal for work on extremely hard materials.
To get the most out of the M3 mod. 380US , it is essential to calculate the optimal rotation speed based on the material to be machined and the diameter of the tool. The basic formula is:
n = (Vc × 1000) / (π × D)
Where:
For example, for a steel tool with a diameter of 10 mm and a recommended cutting speed of 25 m/min, the optimal rotation speed will be approximately 800 rpm.
The M3 mod. 380US is designed to sharpen tools made of HSS (high speed steel), alloy steels, and hard materials such as widia (tungsten carbide). The wide range of grinding wheels available allows you to sharpen different types of tools, ensuring long life of cutting tools and high quality of work.
To maintain the M3 sharpener mod. 380US in perfect condition, regular maintenance is essential. This includes cleaning the grinding wheels and guides, lubricating the moving parts and periodically checking the spindle and cooling system. Furthermore, it is essential to check the condition of the grinding wheels, replacing them when necessary to ensure precision sharpening.
In terms of safety, it is important to comply with current regulations, such as the use of protective glasses and resistant gloves during use. If the machine is not CE certified, it is possible to adapt it to the regulations by installing additional protections and emergency stop systems.
The M3 mod. 380US , if used but in good condition, represents an excellent deal. To evaluate its quality, it is important to check the state of the spindle, check the fluidity of the movements of the swiveling head and make sure that the motor works without abnormal vibrations. Another aspect to check is the state of the grinding wheels and sharpening guides, which must be in good condition to ensure precision.
The M3 sharpener mod. 380US is used in various sectors, such as the mechanical industry, tool workshops and professional sharpening laboratories. Its versatility makes it ideal for sharpening a wide range of tools, from the most common steel cutting tools to widia tools for precision work on hard materials.
Buying an M3 mod. The used 380US is a great opportunity to save on high-quality equipment. The price of a used one is significantly lower than a new one, and if well maintained, it offers performance comparable to a machine that has just left the factory. Furthermore, by purchasing a used machine, you can test an already tested product, avoiding surprises linked to possible manufacturing defects.
In conclusion, the M3 sharpener mod. 380US with chuck represents an ideal choice for those looking for precision, versatility and reliability, with the advantage of a competitive price on the used market.
