Chevalier’s FVL series single-spindle VTC is designed for heavy-duty turning applications on large-diameter parts that require a 78" chuck. The machine is available with optional live tools for flexible machining of complex workpieces. 

 

The machine features a one-piece, Meehanite cast-iron column and bed for damping during heavy cutting application. The wide-span ribbed box structure also decreases vibration, thermal expansion and deformation. With a maximum swing of 98" and turning height of 63", the machine can accommodate parts as heavy as 30,000 lbs.

 

The cross-rail elevation system uses two large ballscrews for positioning and can be locked in any position with four independent hydraulic brake systems. This configuration alleviates overhang by enabling the ram-type spindle to closely approach the workpiece, the company says. 

 

The lock mechanism is equipped with eight hydraulic locking cylinders with curvic coupling to keep the turning holder stationary on the ram. This mechanism provides rigid machining without vibration or chatter and prolongs spindle life by preventing stress on the ram spindle bearings. 

 

The table is supported by double-roller cylindrical bearings that can accommodate heavy parts in aggressive, deep cuts, the company says. The 60-hp Fanuc digital spindle motor with two-speed gearbox can generate up to 6,823 Nm of torque in lower 63 rpm.

  • Building on the Right Foundations

    One of the largest vertical turning and milling centers in the country will be installed in this Cincinnati-area job shop. Although installing the foundation for this huge machine was a massive undertaking, the company is building on other “foundations” as well.

  • Aluminum Molds In Three Weeks Or Less

    While aluminum molds are commonly used to create prototypes or to serve as stopgap bridge tooling, they are starting to receive greater attention for production work. This shop’s approach to creating aluminum molds in one day to three weeks is the same for each of these situations.

  • Multitasking's "Big" Advantage

    As demonstrated at this Cincinnati-area shop, machines that both mill and turn shine brightest when workpieces are massive.
