What are the precautions for CNC processing

Workpiece positioning: ensure accurate workpiece positioning and avoid interference and displacement during processing.

Tool selection and use: select the appropriate tool according to the processing conditions, pay attention to the toughness and hardness of the tool, and avoid unnecessary processing features and thin-wall design.

Machine operation: after starting up, check whether the switches and buttons are normal, and manually lubricate all parts to ensure that the machine is in good condition.

Processing process control: control the processing speed and accuracy, avoid the error of high-precision workpiece, and ensure the accuracy of each step of operation.

Data backup and maintenance: regularly check the battery voltage to ensure that the data will not be lost due to power failure, and timely clean the cutting fluid and iron filings to keep the machine clean.

Detailed operation steps and precautions

After the machine is powered on:

Check whether the switches and buttons are normal and flexible.

Check whether the voltage, oil pressure and air pressure are normal, and conduct manual lubrication.

After the machine is started, each coordinate axis returns to the reference point manually.

During workpiece processing:

When forming high-precision workpiece, use a dial indicator to detect tool runout.

When using the tool for the first time, verify whether its actual length is consistent with the compensation value.

Verify the remaining coordinate value of the coordinate axis under the low-speed feed hold during the trial cutting feed.

After processing:

Check the tool number and compensation value.

Clean the cutting iron filings and cutting fluid in the machine tool.

Check the battery voltage to ensure data security.
