CNC Machining Acrylic Parts

What should be paid attention to in CNC machining of acrylic appearance parts

When CNC machining acrylic appearance parts, the following points should be noted:

1.Tool selection: Choose tools suitable for acrylic processing, such as single or double-edged straight knives, compression tools, etc., to ensure cutting quality and surface smoothness.

2.Processing speed: Acrylic is a material that is easy to process, but processing too fast may cause melting or burning, so it is necessary to control the processing speed appropriately.

3.Cutting depth: Gradually increasing cutting depth can reduce cutting force and heat accumulation to avoid material melting or cracking.

4.Cleaning and Cooling: During the machining process, promptly remove chips and dust, and use an appropriate amount of cutting fluid for cooling to ensure machining quality and tool life.

5.Fixing method: Acrylic material is relatively fragile and requires appropriate fixing methods such as fixtures or glue to maintain the stability and processing accuracy of the material.

6.Avoid serrations: During CNC machining, avoiding serrated cutting edges can be achieved by optimizing tool paths, adjusting cutting parameters, and using appropriate tools.

7.Surface treatment: According to design requirements, necessary surface treatments such as grinding, polishing, or hot bending are carried out to achieve the desired appearance effect.

Please note that acrylic material has a certain degree of brittleness and heat sensitivity, so it is necessary to operate carefully when CNC machining, choose appropriate machining parameters, and follow safety operating procedures to ensure machining quality and safe working environment.
