Chevalier Machinery’s FBB-110 130 series machine is a heavy-duty, high precision design of the FBB series of horizontal boring and milling machine a with rotary table and offers a range of machining applications.
The extra rigid design of the main machine body and column ensure outstanding structural stability, the company says. The one-piece machine base includes four guideways on the Z axis for full table support with no overhang issues.
The series features a one-piece Meehanite cast iron base with heavy-duty large boxways on X, Y and Z axes and is coated with anti-friction material for consistent accuracy and smooth movement. The high-quality C3 grade ballscrews are used on all axes for high precision positioning, the company says.
The 35-hp, 50-taper, large-diameter, cartridge-type, air-purged spindle runs with German made ZF gearbox that generates a maximum of 1,220 foot-pounds at 600 rpm to overcome most tough-material cutting conditions.
Spiral-type spindle cooling system provides constant, all-around lubrication, preventing thermal deformation and substantially, prolonging the life of the spindle, bearings and gears. The spindle can be extended (W axis) for deep-hole boring with high rigidity and superior machining accuracy, the company says.
Editor PickWhy the Surge in HMCs?
Spending on horizontal machining centers is forecast to reach its highest level in more than a decade. Small shops in particular are buying these machines. A shop I recently visited illustrates the reason.
