Kevin Jones, engineering manager at JVM, said: 'The HP400 accelerates in the linear axes at around 1G to 60m/min rapid traverse in all axes, which is fast for a machine of this size with ballscrew drives.

-
With travel up to 1,500mm and load to 150kg, the new stages complement and complete the Pro ballscrew-driven range, which covers stage widths of 115mm, 165mm, 225mm, 28mm and 560mm.
-
It shares the same design as the Type O oilfield grinder, featuring a fixed table and headstock, with a ballscrew-driven wheelhead mounted in maintenance-free, frictionless linear rails traversing in the X and Z axes.
-
The Pro ballscrew-driven series can be supplied separately or together with a choice of
-
The Pro ballscrew range is characterised by its fully protected side-sealed/hard-top design and includes heavy-duty linear motion guide bearings for arduous yet high-precision industrial positioning applications.
-
The 25mm/rev ballscrew and the 2,500 line encoder on the Pro560HS yield a resolution of
-
Motor orientation can be in line with the ballscrew or side mounted on the right or left side of the stage with the 'foldback motor' option to save space.
-
The Pro560 is equipped with a precision-ground 5mm/rev ballscrew and a 2,500 line-motor-mounted encoder for a positioning resolution of 0. 5um and bidirectional repeatability of +/- 1um.
-
By comparison with conventional ballscrew or linear motion systems, the Compact EHA is free from problems of backlash and does not require any form of gearing, so it is unaffected by wear and the loss of positional accuracy.
