How to achieve automatic loading and unloading of CNC internal grinding machine

The spindle speed of the grinding wheel of the CNC internal grinder is very high, and it can grind the surface of cylindrical and conical inner holes, which is only suitable for single piece and small batch production; Automatic and semi-automatic CNC internal cylindrical grinders can not only perform automatic work cycles, but also automatically measure during processing, and are mostly used in large-scale production.

Automatic loading and unloading of CNC internal grinding machine, including a base equipped with machine tool chuck, an installation plate installed at the top of the base, a feeding groove, a horizontal moving device, a rotating device, and a V-shaped feeding arm; Install a servo motor on the mounting plate, and use the active wheel on the servo motor to drive the screw rod installed on the mounting plate to move, causing the screw nut to move on the screw rod and driving the slide table fixed on the screw nut to move forward and backward on the mounting plate.

Transforming the rotational motion of the servo motor into the forward and backward motion of the slide table relative to the machine tool chuck, and cooperating with the rotating device set on the slide table, the output shaft is driven to rotate by the driving motor to drive the feeding arm installed on the output shaft to rotate, achieving fully automatic feeding and unloading of the CNC internal grinder during the grinding process, reducing the workload of the operator, improving production efficiency, with a simple structure, low cost, and smooth output process.

The installation plate for automatic loading and unloading of CNC internal cylindrical grinder has a feeding groove on one end face and a feeding bracket. The feeding bracket is installed on the installation plate and has two semi-circular step surfaces at the top. When the driving motor drives the feeding arm to rotate and unload, the processed workpiece clamped on the feeding spring on the feeding arm can be conveyed to the feeding bracket, and the automatic unloading can be achieved through the step surface of the feeding bracket.

In addition, the tools selected for different purposes are also different. Choosing the right tool for a CNC internal grinder can not only ensure stable machining, but also improve machining efficiency. Here are commonly used cutting tools for CNC internal grinding machines, such as face milling cutters, cylindrical milling cutters, and keyway milling cutters, which can meet different machining applications.
