360° lathe adaptor kit

Unlock the full potential of your lathe. Quickly and easily diagnose specific errors using this ideal extension accessory for QC20 ballbar.

The kit includes:

  • Lathe adaptor arm assembly
  • Spindle bar assembly
  • Spherical adaptor (with magnetic centre cup)
  • Cup screw (with magnetic centre cup)
  • Carrying case

Machine requirements

X-axis clearance:

≥ 220 mm from centre line

Y-axis clearance:

≥ 330 mm from chuck

Spindle diameter:

ø25 mm (others will require additional magnetic base)

Tool header:

accepts 20 mm or 25 mm tool shanks

CNC control:

circular interpolation in ZX plane

On lathes with restricted axis travel, it may be possible to perform a 50 mm radius test using the small circle accessory kit. It is crucial to ensure that there is clearance for the ballbar in this configuration before performing the test.

QC20 with lathe adaptor

VTL adaptor

Easily diagnose and assess vertical turning lathes, laser cutting machines and pick and place machines with the VTL adaptor.

For tests performed in the ZX plane, the VTL adaptor allows the magnetic centre cup to be retracted after centring, without losing centre location. This enables the machine to be moved to the test start position.

The VTL adaptor includes:

  • VTL adaptor
  • Centre cup

Small circle accessory kit

This small circle accessory kit allows the QC20 ballbar to perform 50 mm radius tests (standard minimum is 100 mm). This provides enhanced analysis of servo control systems on most types of machines.

The kit includes:

  • QC20 small circle adaptor
  • Ballbar calibrator (50 mm)

Ballbar spindle centring device

Ballbar spindle centring device

The ballbar spindle centring device has been designed to simplify the set-up requirements when using QC20 ball bar for ISO 10791-6.

The device helps to centralise the tool cup tip with the spindle centreline which is critical for this test.

The QC20 ballbar for machine tool verification is highly recommended within the industry and is leading the way in machine tool diagnostics.
