After tool installation, the 850 machining center needs to perform tool alignment to determine the starting point position before executing the machining program. However, tool adjustment is often a headache for operators, which is time-consuming and labor-intensive, especially when processing multiple tools, and requires measuring the tool compensation value. EMAR has multiple high-precision 850 series CNC Machining centers and shares common tool alignment methods with you, mainly including:

1、 Using self-made knife block method

A simple tool block made of plastic, organic glass, etc. can easily achieve repeated positioning of the tool after grinding, but the positioning accuracy is poor, usually between 0.2-0.5mm. However, it is still a fast positioning method and can be easily adjusted again.

2、 Point to move knife technique

Press and hold the jog key on the control panel of the 850 machining center, lightly touch the surface of the workpiece with the tip of the tool, reset the counter, then return to the desired initial position, reset again, and obtain the initial position of the tool. Determine the initial position of each knife in sequence, and adjust it to the accurate design position after trial processing.

3、 Using CNC cutting tools

After the initial positioning of the 850 machining center tool installation, wear occurs after a period of cutting and requires sharpening. The position of the tool tip changes when reinstalling a regular tool after sharpening, and it needs to be re aligned.

The 850 machining center adopts the tool presetter method. The tool presetter selected for the machine tool has a self-test device, but the operation is complex and still requires a certain amount of preparation time. Suitable for use in multi blade measurements.
