Does 从来 translate to "always"? Does anyone know if 从来 translates to "always"? And if it is, is it used in the same way?
For example if I want to say: "I always buy oranges", would that be “我从来买橘子”？
Without 都, 从来 does not mean always. 从来 actually means from (从) past till present (来). It is obvious where the always come from by looking at the example given by NS.X:


  他每天一起床就喝咖啡，从来都是这样。


Everyday, he drinks coffee when he wakes up. From past till present, it has always been like this.

每天      他  喝    咖啡   就      一起床     从           来           都     是   这样


See grammar usage here.

If you want to say "I always buy oranges", you can try using 向来都 instead. For example:


  我向来都是买橘子的。


向来 means all along.
都 makes it always.
