Broken Needles And Service Life lssue

The cutting edges on the surface of the file are too deeply serrated, causing stress to concentrate atthe serrations, Eventually, the file breaks.
The rough surface of the needle body will significantly reduce the fatigue limit of the root canal file.

Issues Related to the Doctor-patient Experience

After the file is ground, there are sawtooth-ike burrs on the edge. Removing these burrs will reduceits original sharpness, resulting in significant variation in cutting performance. it also dulls the edgeand increases the treatment time
Doctors need to frequently adapt to the diferent feel of the drils, which makes it difficult for them toform a stable muscle memory and thus affects the continuity of their operations.

HFS Solution

Lifespan Extension Technology

HFS can create surfaces with almost no scratches and achieve a micron-level roughness control level providing a hidden armor for the cutting tool and significantly reducing the risk of stress concentration.This greatly enhances the service life.

Surface Roughness Comparison

Precision Cutting Edge Technology

Micro-metric standardized production results in minimal burrs at the cutting edge. During deburring,the sharpness can be maintained. Each file has uniform cutting force.
The product batch accuracy is ±5 μm, The doctor's operation feels stable and smooth, reducing thetreatment time.

Why we can achieve this?

Core technology: 5-Axis micron-level root canal file needle grinder

Imported Grinding Wheel

Imported grinding wheels are used, and they are dressed into the correct shape with a grinding wheel dresser. The dimensions after dressing are precisely measured with a tool setter (achieving an accuracy of 0.002mm), and this enables long-term stable high-precision processing.

Robotic Loading and Unloading

Equipped with automatic loading and unloading system, it can realize efficient machining of shaft and disk parts, suitable for mass production.

Designated Workpiece Tray

The grinding machine uses a designated workpiece tray to store the files, which can prevent the files from coliding and facilitate quality inspection.

High-precision Constant Temperature System

The grinding machine is equipped with a high-precision constant-temperature filtration system, which ensures a stable grinding environment and enables stable control of dimensions within +0.005mm and a surface roughness of Ra 0.05μm.

5-Axis Micron-level Root Canal File Needle Grinder

Five-axis machining mode main grinding can be tilted angle. Can process any one of the root canal file needle on the market. Machine tool processing form is mainly high-speed, high-precision profile grinding, with 5 servo spindles and 2 right-angle coordinate system robot servo axis. The highly reliable right-angle manipulator mechanism enables unmanned production of large quantities. Meanwhile, it adopts a higher precision center pallet and self-developed straightening bar, thus ensuring the stability of the grinding process.
