"punch die" översatte jag först med "stansdyna" som är den översättning som står i min tekniska ordbok. Men eftersom jag ändrade nyckeltermernas översättning till "körnare" och "stämpelmaskin" undrar jag om det går att frångå ordet "stans" och säga "körnardyna"?

Sammanhanget är en bruksanvisning för en stämpelmaskin med körnare i kapitlet Technical description i avsnittet om magnetkörnaren (se andra raden nerifrån):

"The magnet punch unit consists of a house (12) with two embedded coils, an upper (13) and a lower (15) coil. A spacer (14) is embedded between two coils. A top cover (10) with a radial bearing (11) fitted with a snap ring (9) is mounted at the top of the coil house. A buffer house (2) containing a buffer (3) with an adjustment screw (1) is mounted at the top cover. The buffer house is held in place by four springs (7) attached to two spring holders (6), which are fastened with four centre bolts (5). The armature (16) is mounted in the coil house and is held upright by means of a spring (8), which is kept in place by a nut (4) at the top of the armature. A steering (17) is mounted at the bottom of the coil house. A hard metal punch die (22) is mounted on the armature, and the punch die is fastened with a union nut (21). The armature is controlled at the bottom by a radial bearing (18)."
