FAQ


Q

How to Select Cutting Tools Appropriately Based on Different Machining Operations

+

A

Machining centers can perform a variety of operations, but different machining processes require different types of cutting tools. The general principles for tool selection should be: ease of installation and adjustment, good rigidity, and high durability and precision. Provided that machining requirements are met, shorter shanks should be chosen to enhance tool‑holding rigidity. When selecting tools, ensure that their dimensions are compatible with the surface geometry of the workpiece being machined.
When machining the peripheral contours of planar parts, it is recommended to use end mills.
When milling flat surfaces, it is recommended to use carbide-insert milling cutters.
When roughing—i.e., machining the blank’s surface—it is recommended to use a corn‑shaped end mill with a carbide insert.
Selecting the appropriate cutting tool is essential to achieving precise, seamless machining and preventing process deviations caused by unsuitable tools, which can lead to tool collisions.

Q

In summer, the weather is so hot—why can’t we open the CNC cabinet to allow it to dissipate heat?

+

A

In summer, to enable the CNC system to operate continuously under heavy load, some people open the CNC cabinet door to improve heat dissipation. Is this approach advisable?
The air in machining workshops typically contains oil mist, dust, and even metal particles. If these contaminants settle on the circuit boards or electronic components within a CNC system, they can reduce the insulation resistance between components and may even cause damage to the components and circuit boards.
Opening the doors of CNC cabinets to dissipate heat will ultimately accelerate the deterioration of the CNC system. Therefore, during extremely hot summer weather, it is advisable to minimize opening the doors of both the CNC cabinet and the high-voltage electrical cabinet. So, how should a CNC system be maintained?
