Muratec MW320

The Muratec MW320 is a CNC Swiss-type automatic lathe with 32mm bar capacity and an integrated back spindle, positioned at the upper diameter range of the Swiss-type class. The 32mm capacity is the most common maximum for high-end Swiss-type automatics and covers a wide range of medium-diameter precision parts: orthopedic bone screw blanks, aerospace fastener bodies, hydraulic fitting adapters, automotive turbocharger components, and industrial valve stems — all applications where the Swiss architecture's single-setup complete machining advantage is commercially decisive. The MW320 brings Muratec's precision engineering to this demanding segment with a back spindle configuration that enables complete part machining from bar without operator intervention.

The back spindle on the MW320 is not merely a cut-off receiver — it is a fully functional CNC spindle with its own driven tooling positions. After the main spindle completes front-face machining and the part is cut off and transferred, the back spindle executes independent secondary operations: back-face turning, drilling, threading, chamfering, and milling. These operations proceed simultaneously with the next part's front machining cycle on the main spindle, so the machine operates both spindles in parallel. For complex parts requiring substantial back-end machining, this parallel operation is where the MW320's productivity advantage over simpler Swiss-type configurations is most pronounced.

Muratec's structural design for the MW320 addresses the rigidity requirements of 32mm-diameter Swiss-type work. At this diameter, cutting forces during heavy turning and milling operations are substantially greater than on smaller Swiss platforms, and the MW320's headstock, guide bushing support, and tool slide structures are scaled to maintain stiffness under productive cutting loads. Spindle power on both the main and back spindles is appropriately rated for aggressive material removal in stainless steel, titanium, and brass at 32mm diameter.

For manufacturers of medium-diameter precision parts who require the complete machining capability of the Swiss-type architecture — avoiding the separate turning, milling, and deburring operations that conventional CNC turning requires — the MW320 delivers Muratec's precision quality at the most commercially significant Swiss-type diameter. The 32mm capacity combined with back spindle parallel machining makes the MW320 applicable across orthopedic implants, aerospace fasteners, hydraulic fittings, and industrial precision components.
