Question

why did the Sikhs become Aurangzeb enemies​

Answer 1

One thing is sure that none Sikh Guru asked thier followers to hate Muslims or create enemity with them.

But circumstances did this. The first was the killing of 5th Nanak (Guru Arjan Dev ji) by order of Jahangir in 1606, Second, the killing of 9th Nanak (Guru Teg Bahadur ji) at Delhi in 1675 by the order of Aurangzeb. The third clash of the Mughals with the 10th Nanak (Guru Gobind Singh ji) during early 18th century which was the longest one strengthen this enemity.  The Hindus, who were being supressed by the Mughal rulers, played important role in strengthening this enemity by inciting the Sikhs against the Muslims by feeding poisonous thoughts that the Sikhism has been created to uproot the Muslim rule from the Indian soil, which is totally wrong.  Because of killing of two of the Sikh Gurus by the Muslim rulers, the Sikhs were already against the Muslims, the inocent Sikhs accepted this false notion of the Hindus and bent upon to uproot the Muslim rule from the Indian soil. This further intensified this enemity. This hatred intensified the clash further which went up to 1765 when the Mughal in Punjab totally surrendered before the Sikhs.  Till today we find this hatred in heart of both, but it shouldn’t be.  The Sikhs have gained nothing but lost a lot in this clash.
