MAG offers an integrated contouring head for its horizontal boring mills in 1,250 and 1,600 mm (49.1" and 63") table/pallet sizes and live spindle HMCs in 800 to 1,600 mm (31.5" to 63") pallet sizes.
The contouring head has a standard tool interface that loads tools via the machine's automatic tool changer for faster processing without operator involvement. The contouring spindle's U-axis slide stroke provides the ability to produce small- or large-diameter features without head changing or manual intervention, allowing complex features to be machined in one setup. The contouring head can produce features such as bottle bores, valve seats, seal faces, phonographic sealing surfaces, O-ring grooves, straight/tapered threads, chamfers, external profiles and others. According to the company, it is ideal for single-setup, rough and finish machining of oil and gas parts or any large part that combines bored, milled and turned features.
The integrated contouring head is available with a standard Kennametal KM80 or Sandvik Coromant Capto C8 tool interface. The live boring spindle can use 50-taper tools as long as 750 mm (29.5"), and an auto-coupler provides the interface for use of feedout tools, such as programmable boring bars.
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 (S6-40%) on boring mills and 45 kW/60 HP (S6-40%) on HMCs. A touch probe can be used in the boring spindle or on an auxiliary arm for in-process or post-process measurement of part features machined by the contouring spindle. Standard services, such as coolant supply, are plumbed through the contouring head to eliminate manual intervention and maximize tool life.
"The contouring head is engineered as a drop-in module that can be added during manufacture or later, as well as removed for service without affecting operation of the boring spindle," said Pete Beyer, MAG Director, Product Strategy and Product Development. "A simple shifting mechanism allows it to be powered by the main spindle motor, reducing complexity and cost. In addition to providing greater slide stroke, our design includes a slide counterbalance to offset centrifugal force, ensuring optimum part roundness and accuracy. Overall, the integrated contouring head is a great advance over current boring mill technology, which would require two auxiliary heads to produce the same diameter range; a head changing system and storage rack; manual tool changes; and proprietary tools to provide the same functionality."
