The cutting of automotive connector samples for today's sample preparation method sharing is as follows:

     Difficulties:

     1. The connector has multiple materials and structures inside, and must be embedded to fix the structural components before cutting

     2. The connector housing is mostly made of polymer plastic and has protruding edges, making it difficult to fix the cutting fixture

     3. L-shaped connectors, with the short edge cut very close to the edge, need to minimize cutting losses as much as possible

     1、 Sample size and cutting position

     2、 The connection position of the connector is pre embedded to fix the structural components

     Step:

     &Bull; Pour in epoxy resin first, then pour in curing agent

     &Bull; Slowly stir in one direction for about 2 minutes

     &Bull; Pour one end of the connector

     &Bull; Lock the connector again and let it sit for more than 2 hours

     Consumables:

     EpoQuick epoxy resin and curing agent

     Curing time: 2 hours Transparency: transparent Shore hardness: 80

     Peak exothermic temperature: 110 ℃ Volume/weight mixing ratio: 5:1

     3、 Cutting

     1. Selection of cutting machine and cutting blade

     Cutting machine: 10 inch manual grinding wheel cutting machine METCUT-10

     Bearing speed: 2865rpm/min

     Cutting capacity: 90mm

     Cutting blade: 10 inch diamond cutting blade CD-10-01, thickness 1.5mm

     Cooling liquid: water-based cutting cooling lubricant CC-01 Sample fixture: left and right hand quick fixture

     Operation mode: Z-axis manual direct cutting load display: ammeter

     2. Fix the sample with a quick fixture

     3. Taking the L-shaped 2021493A02 as an example

     4. Manually grind for 2 minutes on METPOL-A using P1200 # sandpaper to remove cutting marks on polymers such as rubber and plastic
