Product overview

DNM 6700 is a VMC supplied by DN Solutions(Doosan Korea). This machine is a 3-axis machining center with a C-frame structure in which the milling head moves up and down along the column (Z-axis), the saddle moves back and forth on the bed (Y-axis), and the table moves from side to side on the saddle (X-axis). The table is a rectangule, and the size is 1500X670 mm. The stroke is X 1300 mm Y 670 mm Z 625 mm.

Series introduction

Many companies manufacture vertical machining centers. Among them, DN Solutions supplies vertical machining centers with high reliability and performance that comply with quality processes in manufacturing, have traceable design change histories to enable accurate parts supply for each machine even after the warranty period expires, and have accumulated proprietary technology through know-how accumulation.

With more than 50,000 units sold worldwide, the DNM series is a reliable vertical machining center with consistent quality and outstanding performance, and its 8000 rpm spindle for general machining and 12000 rpm/15000 rpm spindle for high-speed machining are popular in semiconductor applications. This machine is highly resistant to thermal deformation due to its direct-coupled spindle construction. When it comes to capital investment, price matters. To purchase a machine from DN Solutions, contact Puma Machine Tool (China +86 177 2394 1337).
