Abstract
A computerized numerically controlled drilling and milling machine has a worktable 2, 3 for supporting a workpiece 41, one or more tool assemblies 10, 11, 26 for processing the workpiece, and feeding and guiding devices 8, 9; 24, 25; 27, 43 arranged to provide for positioning and simultaneous relative movement between the tool assemblies and the workpiece in a longitudinal as well as a transverse direction. The worktable is in two parts, and the tool assemblies are arranged on the guiding devices in a transversely extending intermediate space 4 between the parts. Further, a clamping and feeding device 30, 44, 27, 43 for the workpiece is provided on each side of the intermediate space for successive alternating feeding of the workpiece.
Claims7
A machine for processing workpieces, comprising:
- a) a bipartite worktable for the support of a workpiece,
- b) tool assemblies movably arranged on transverse guiding means in an intermediate space between the worktables, for processing the workpiece,
- c) a clamping and feeding means on each worktable for engagement with transverse side edges of the workpiece, and for feeding the workpiece during the processing thereof, and
- d) at least one cooperating pair of upper and lower guiding and pressure applying means arranged in said intermediate space, for the stable support of the workpiece in said intermediate space,
- e) said clamping and feeding means being mounted on longitudinally extending guiding means and arranged to clamp the workpiece separately or simultaneously, and being independently movable for positioning the workpiece during processing and for successive alternating feeding of the workpiece, a forward one of the clamping means, as viewed in a feed direction, being arranged to take over the workpiece when said workpiece has been fed to a suitable take-over position by a rearward one of the clamping means.
