Key product features
-
The base of the centerless grinder is made of high-grade cast iron (FC30) and has undergone normalized heat treatment. The double V-shaped lubrication design ensures that there is no fear of deformation of the body after long-term use.
-
The fine adjustment of the upper and lower feed can reach 0.001mm.
-
The grinding wheel dressing device can be adjusted ±6°, and the interface between the workpiece and the adjusting wheel is precise.
-
The most extensive series of machine selections to meet various grinding needs.
-
The most complete optional equipment improves operating functions and convenience.
-
The machinery has undergone the most stringent testing and quality control to ensure top performance, precision and the lowest failure rate.
-
The grinding wheel and adjustment device are hydraulically driven, with stepless speed change, and the dressing is smooth and the dressing seat is made of special alloy cast iron, which has been roasted and precision scraped to ensure smooth and straight dressing.
-
The adjusting wheel is driven by a servo motor, which can be adjusted to the appropriate speed at will, and the worm rod is used in conjunction with the turbine to directly drive the main shaft. It can obtain better roundness due to the fewer transmission parts.
-
The spindle lubricating oil can be reduced to reduce thermal deformation and extend the life of oil seals, spindles and alloy bearings.
-
The pressure switch in the automatic lubrication system of the grinding wheel spindle bearing. When the lubricating oil pressure does not reach the rated value, the spindle motor cannot start or will automatically stop rotating to avoid damage to the spindle due to rotation.
-
Intuitively detect whether the circulating oil has deteriorated to ensure the normal operation of the spindle.
-
During grinding, adjusting this angle can effectively change the grinding accuracy of the workpiece.
-
Used to change the grinding wheel or adjust the dressing direction and speed of the wheel.
-
The axial advancement speed of the workpiece is adjusted by changing the inclination angle.
-
It prompts the spindle to work under the normal circulating oil pressure value, and automatically shuts down for protection when the pressure exceeds the standard.
-
In response to the increasing demand for automation, various automatic feeding and collecting devices have been designed for through-type grinding of round pipes, shafts and rods, and are suitable for grinding a large number of workpieces.
-
This fully automated device significantly reduces original production and manufacturing costs, while also increasing production capacity.
-
In response to the top, shoulder and multi-diameter grinding parts, various forms of stop grinding, the automatic feeding and retracting device can be designed according to the shape and length of the workpiece.
-
Such a fully automated device not only reduces operational errors and saves labor costs, but also enhances production efficiency.
