J4M Horizontal Machining 4 Axis

With its high speed and outstanding accuracy, the J4M is designed for flexible transfer lines and is primarily intended for the economic machining of aluminum parts such as cylinder heads and crankcases for four-cylinder motors, gearboxes and attaching parts. An innovative space- and energy-saving design adds to its flexibility. The J4M can be easily integrated into different automation concepts, thanks to its three axes in the tool and a fourth NC axis in the table.

Additional Information:

  • The J4M features a spindle speed of 16,000 rpm, an axis travel of 60mm/min and an acceleration of 1.2 g.
  • A unique feature of the machine is the availability of an additional tool magazine that allows the use of the special tools in the W-axis of the table. This makes it possible to handle hydrostatically mounted boring bars for camshaft and crankshaft bearing seats with a length of up to 700mm, as well as a 3-D chucking mechanism to gang arbour heads for the machining of bearing seats inside the machine. This means additional, specialized machines are no longer needed.
