Posts from Custom Post Type and Custom Post Type Category

Hi,

I’m trying to list all the posts within my Custom Post Type (News) that are of a particular custom category (Machine Tools).

I’ve been using the following code

<?php								 $cust_post_type = get_post_type();
$args = array(
	'post_type' => 'news',
		'tax_query' => array(
			array(
				'taxonomy' => 'news_cat',
				'field' => 'slug',
				'terms' => 'machine-tools'
			)
		)
	);
	$products = new WP_Query( $args );
	if( $products->have_posts() ) {
		while( $products->have_posts() ) {
			$products->the_post();
?>
<div class="row">
<div class="five columns">
<a href="<?php the_permalink(); ?>"><?php the_post_thumbnail('news-thumb'); ?></a>
</div>
<div class="seven columns">
<h4 style="margin-top:0px;padding-top:0px;"><?php the_title(); ?></h4>
<?php the_excerpt(); ?>
</div>
<hr style="margin: 10px 0 20px 0;" />
</div>
<?php
		}
	}
	else {
echo 'There are currently no news stories available.';
	}
?>

But I’m still unable to get any results through it. Has anybody got any ideas?
