1. In all machining applications, use short tool holders whenever possible. In addition, the tool should be installed in the tool holder as much as possible. This improves the toolholder's grip on the tool and reduces vibration. The shorter the distance from the spindle nose to the tool tip on a high-speed machine, the higher the rigidity; higher rigidity means less vibration during the cutting process.
2. Do not use inferior quality collets. The ER style (double angle) collet is a high performance, general purpose collet that offers flexibility and performs well in most machining applications. This collet performs slightly worse when holding end mills for heavy roughing operations. Compared with side-locked collets, heat-sleeved collets or hydraulic collets, ER collets have a slightly weaker clamping force. Side forces on end mills can produce tool vibration or chatter, and the helical shape on some tools can pull the tool out of the collet. ,
3. It is recommended that all tool holders with a rotation speed of 10,000 rpm or higher be dynamically balanced to G2.5 or higher at the maximum rotation speed. It is also possible to order a balanced toolholder, but the tool will need to be balanced again after it is installed in the toolholder.
4. Use appropriate rotational speed and feed rate when performing cutting operations. Most tool manufacturers provide general guidelines for the use of the tool (based on the material being processed). Although the manufacturer's recommendations for tool rpm and feed rates are provided for your convenience, they are for reference only. In most cases, these recommended values are based on ideal conditions and may not apply in all cases. Experience is valuable for adjusting the cutting conditions of the tool. Chatter and vibration may occur, and you may need to change RPM and feed rates to improve these conditions.
5. Use tool load monitoring in the machine tool controller. Tool and insert wear, as well as increased spindle load, are the first signs that tool cutting performance is beginning to decline. When a new tool is at peak performance, spindle load is detected and recorded on the Tool Load Monitoring page. Using tool load monitoring, it is possible to define a load limit for each tool and notify the operator to replace the tool or insert when the load rises to this limit.
