Technology and Application of CNC Prototype Machining
CNC prototype machining is traditional machining method which cut out excess material in
solid pieces. In CNC prototype machining industry,CNC prototype machining generally apply
in large-sized workpiece and appearance prototype. There is a wide material selection for
CNC prototype machining, including ABS, PMMA, POM, PC , acrylic, etc.There is a low cost for
CNC prototype machining,but high requirements for machining plastic material includes high
strength,high temperature resistance, high tenacity, transparent, etc. There are many kinds of
surface treatments for CNC prototype including polishing, spraying putty, spraying paints, shining,
silk-screening, plating, etc, which can completely match with products produced by moulding.
Appearance, assembly , functional test can reach clients’ final design. Therefore, CNC prototype
machining has become mainstream manufacturing method for prototype machining.
CNC prototype machining generally apply to mobile phone, PDA, digital camera, household
appliances computer, air conditioner,TV set, electric piano, display, speaker, medical devices,
motorbike, automobile parts, etc.
CNC prototype material analysis:
ABS material
Temperature resistance : 60-80℃
Feature: general strength and tenacity
Application scope : enclosure of electric equipment
PMMA material (Acrylics)
Temperature resistance : 60-80℃
Feature: high transparency but bad strength and tenacity.
Application scope : LCD enclosure of electric equipment
POM material
Temperature resistance : 90-110℃
Feature:good strength ,tenacity and hardness
Application scope : Mechanical gear, rotating components
PC material
Temperature resistance : 90-110℃
Feature: translucence and general strength ,tenacity and hardness
Application scope : auto rice cooker, electric iron
