Series BG/RH/NT
Flat bevel grinding machine for radii grinding
BG/RH/NT: Radii grinding
The CNC-controlled flat bevel grinding machine of the series BG/RH/NT is designed for grinding curved blades at pruners, hedge shears, axes, hand tools, circular knives and similar pieces. The grinding machine is equipped with up to five contour giving axes and one tool axis.
In addition to the technical data indicated at BG/NT the machine is classified by the technical specifications as follows:
- grinding length 300–640 mm
- reception flange for grinding wheel: 80–710 mm ∅
- spindle drive 6.5–45 kW
- precision mounted grinding spindle, designed for circumferential speed of up to 50 m/s
- grinding table with five axes:
- X-axis = main feed axis of the grinding table, powered by a linear motor
- Y- and Z-axis = linear pressing axis against grinding wheel
- A-axis = tilt axis/grinding angle
- C-axis = horizontal axis of rotation
- W-axis = infeed axis for grinding wheel, continuously adjustable and freely programmable
- digital drive for the axes, preloaded ball bearing spindle, A- and C-axis, digital axis drive with linear motor for X-axis
