Posted Date: 6/19/2012
Powermatic is laying all of its cards on the table with the new 4224B Lathe
, likening it to the Lamborghini or Stradivarius of lathes. And, given the impressive standard features that come on this new 950-lb. machine, that just might be an apt description. The lathe provides 42 in. of working distance between centers and a 24-in. swing over bed. Its headstock, tailstock, legs and bed all are cast-iron, to dampen vibration and add stability for big turnings. Two inch diameter adjustable feet level it on uneven shop floors. The headstock features a 3hp, three-phase motor with built-in converter for incoming singe-phase power. Electronic variable speed enables infinite adjustment of the spindle between 40 and 3,500 rpm, and a digital readout tracks the current speed. Forward and reverse rotation will promote both conventional turning and sanding reversing, difficult grain. A 98-position indexing system makes it easy to set up evenly spaced turning details. Open access eliminates the need to remove the headstock cover to change between settings, and a spindle lock engages by pressing a button to attach or remove workpieces. A Venturi system provides a fully integrated solution for vacuum chucking. The headstock can be rotated for outboard turning, too. A comparator system on the machine provides a mount for duplicating tasks so a second turning is within easy reach for measurement and visual comparison.
The behemoth machine also comes with a 14-in. tool-rest, cam-action locking devices for the headstock and tailstock and an impressive array of electrical extras: twin 100-watt task lights, four 115-volt outlets for powering other tools and an On/Off switch that can be positioned anywhere along the lathe bed using a magnetic base. Accessories include 20- and 63-in. extension beds, which boost the bed length to a total capacity of 62 in. or 105 in. respectively. A guard and tool storage rack come standard. The machine, which is available now, has a street price of $7,499.99. The 20-in. bed extension package will add another $1,472 to the sticker price, and the 63-in. extension sells for $2,753.
