Honing machine

Honing machine for honing a bore in a workpiece, comprising:

• a support structure fixed to the machine;
• at least one honing unit mounted on the support structure and comprising:
• a main support configured to be mounted fixedly in relation to the support structure,
• a spindle unit supported by the main support and in which a spindle shaft is rotatably mounted, wherein the spindle shaft is rotatable about a spindle axis by means of a rotary drive and, at a tool-side end, comprises a device for the fastening of a honing tool,
• a linear guide system arranged between the main support and the spindle unit and serving for guiding a linear stroke movement of the spindle unit relative to the main support;
• a stroke drive for generating the stroke movement of the spindle unit;
• and
• an alignment system for setting the alignment of the spindle axis in relation to the support structure,
• wherein the alignment system is configured for a continuously variable, reversible setting of the alignment of the spindle axis in relation to the support structure,
• wherein the alignment system is configured for an independent setting of the position of the spindle axis along two mutually perpendicular axes of translation and for a setting of the orientation of the spindle axis in relation to two mutually perpendicular axes of rotation,
• wherein the alignment system comprises a first setting unit and a second setting unit which is separate from the first setting unit and which is arranged with a spacing to the first setting unit, wherein each of the setting units comprises first setting elements for a continuously variable adjustment of a spacing between the support structure and the main support in a first direction and second setting elements for a generation of a continuously variable relative movement of the main support relative to the support structure in a second direction perpendicular to the first direction.
