国家机器 is a fixed political term meaning 'state apparatus' or 'machinery of state'. It refers collectively to the institutions and organizations through which a state exercises power—including the government, military, courts, police, and bureaucracy. Unlike the literal reading 'national machine', the term carries ideological weight and is used in political science and discourse, especially in Marxist and Chinese political contexts. You'll encounter it in discussions about state power, governance, and reform.
