Integrated Contouring Head for Boring Mills and HMCs

Mag offers an integrated contouring head for horizontal boring mills in 1,250 and 1,600 mm (49.1" and 63") table/pallet sizes and live-spindle horizontal machining centers in 800 to 1,600 mm (31.5" to 63") pallet size. The contouring head can produce bottle bores, valve seats, seal faces, phonographic sealing surfaces, O-ring grooves, straight/tapered threads, chamfers, external profiles and other features. It is designed for single-setup rough and finish machining for oil and gas parts, or other large parts that combine bored, milled and turned features. The head is available with a Kennametal KM80 or Sandvik Coromant Capto C8 tool interface.

 

The contouring head has a standard tool interface and loads tools via the machine’s automatic toolchanger. An absolute positioning slide handles diameters ranging from 50 to 540 mm (2" to 21") with tools as long as 600 mm (24"). The contouring spindle’s U-axis slide stroke provides the ability to produce small- or large-diameter features without head changing or manual intervention for machining complex features in a single set up. The live boring spindle can use 50 taper tools as long as 750 mm (29.5"). An auto-coupler enables the use of feed-out tools such as programmable boring bars.

 

The head is designed as a drop-in module that can be added during manufacture or later and removed for service without affecting the operation of the boring spindle, the company says. The contouring spindle for both boring mills and HMCs is located immediately above the machine’s main spindle but slightly offset in the Y and W/Z axes to avoid tool interference. Rated power is 56 kW/75 hp on boring mills, and 45 kW/60 hp on HMCs.
