Dental Rotary Files Needles Grinder Grinding Machine

Main Features

Among the equipment required for the processing and production of root canal files, the root canal file grinder is the first step in the production of root canal files. Its main function is to process and cut the nickel-titanium alloy wire with a diameter of 1.0mm or 1.2mm according to the taper and length required by different models. In particular, the tip diameter can reach 0.015mm according to different models. This requires very high precision for the root canal file grinder, especially for the beating problem caused by the traditional mechanical axis plus motor movement in the process of grinding the nickel-titanium wire by the grinding wheel, which will have a significant impact on the qualified rate of root canal files in the production process. After many tests and mechanical structure design, our company has developed a root canal file grinder that fundamentally solves the spindle beating problem and accurately calculates the beating data to microns, which means that the important factor affecting the product qualification rate due to the beating node in the production process has been solved. In addition, our control system program, specially designed for root canal file production, has also been greatly improved in production efficiency.

Main Functions

When choosing a grinder for root canal file processing, the first consideration is the stability and efficiency of the equipment, which is closely related to the later benefits, similar to the operating efficiency of mobile phones or computers, which directly affects our work output.

When choosing a root canal file grinder, the stability of the equipment operation becomes the focus. The double-clamping shaft design effectively reduces the vibration of the electric spindle during operation, and the electric spindle shows excellent stability during the long-term grinding process, ensuring that the equipment remains stable when the spindle continues to work for a long time, and can maintain high precision during long-term operation. This not only ensures the continuous qualification of the workpiece product, reduces the frequency of workers’ adjustments but also extends the service life of the grinding wheel.

Especially for the variable cone and spiral parts of the root canal file, different models have more stringent requirements on the equipment. The motion control system of our company’s dental file grinder, with precise servo motor control, can meet the processing needs of various types of file bodies.
