Nylon/PA 6 Machining Overview

Nylon is one of the most widely used engineering plastic. The good impact strength, resistance to many grease, very good wear resistance, and great sliding performance of this material can not be replaced by other plastics. For some modified nylon material, it is better to the pre-heating before machining.

Nylon/PA 6 Machining Guide

PA 6 Sawing

Material	Rotate Speed [rpm]	Circular Pitch
Nylon Virgin	2000~2600	31~38
Nylon Modified	2400~2800	20~24

PA 6 Drilling

Material	Number of Teeth	Helix Angle	Approach Angle	Cutting Speed [rpm]	Feed Force [mm/r]
Nylon Virgin	Z2	25	90	50~150	0.1~0.3
Nylon Reinforced	Z2	25	100	80~100	0.1~0.3

Note: Only for Keward Plastics. It is better to do pre-heating when the diameter of pa 6 glass fiber filled plastic is larger than 100mm.

PA 6 Milling

Material	Number of Teeth	Cutting Speed [rpm]	Feed Force [mm/r]
Nylon Virgin	Z2~Z4	250~500	0.1~0.45
Nylon Reinforced	Z2~Z4	80~150	0.05~0.4

PA 6 Turning

Material	Relief Angle	Approach Angle	Corner	Cutting Speed [rpm]	Feed Force [mm/r]
Nylon Virgin	6~10	0~5	45~60	250~500	0.1~0.5
Nylon Reinforced	6~8	2~8	45~60	80~150	0.1~0.5

Note: Only for Keward Plastics.

Nylon/PA 6 Heat Treatment

Material	Heating	Keeping	Cooling
PA 6	3h heating to 90℃, then 3h heating to 160℃	1h/10mm thickness	cooling to 40℃ at speed of 20℃/h

Note: Only for Keward Plastics. The heat treatment above is a rough numbers, and only suit for the components which the thickness is less than 50mm. If the thickness is larger than 50mm, Please Send Us Email.
