How to Use Double Edge Clay Knives Properly to Avoid Burrs and Overheating

2025-08-05

In the field of industrial modeling and rapid prototyping, the double-edged clay knife has become a commonly used tool for handling soft materials. However, in daily use, if the operation method is improper, problems such as burrs on the hole edge, uneven cutting, or tool overheating may still occur. Recently, the AMG technical team provided professional advice on how to correctly use double-edged oil mud knives, helping users improve processing quality in practical applications.


According to AMG, the common reason for burrs on the edge of holes is unstable feed angle or too fast feed. It is recommended that the user should maintain a stable and even feed speed when using the double edge putty knife, and ensure that the cutting angle between the knife edge and the contact surface of the workpiece is stable to avoid vibration or tool jumping, especially when dealing with easily deformed materials such as putty and PU foam.


To prevent tool overheating, AMG recommends controlling the spindle speed and cutting depth appropriately, especially during long-term continuous machining. Intermittent operation or the use of an external cold air gun should be considered to reduce the temperature in the cutting area. High temperature not only accelerates blade wear, but may also cause material melting and blockage of blade grooves.


In addition, AMG recommends users to regularly check the wear and tear of cutting tools, keep the cutting edge sharp, and avoid rough edges caused by blunt cutting. If the usage scenario is high-precision surface finishing, the hard alloy version of the double-edged oil mud knife can be selected to achieve more durable and stable cutting effects.
