TAC Rockford gauges are used for inspection of steep taper spindle tapers per CAT, ISO, JIS, DIN, etc. Available for Steep Taper 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65
When inserted in the spindle, the "go" gauge should be in contact with the plane face. The "no go" gauge should not contact the face. Two measuring gauges in storage case: "go" and "no go" plug gauges.
The four transducers mounted in the measuring ring are used for differential measurement of gauge dimensions d2 and d3. Deviations from the calibrated taper plug gauge are shown on the two indicator columns.
Both measuring gauges are set to zero with the calibrated taper plug gauge. When an HSK tool holder is inserted in the ring gauges, deviations in diameters d2 or d3 are shown on the indicator.
Available for Steep Taper CAT/ANSI/DIN/BT/ISO 10, 15, 20, 25, 30, 35 40, 45, 50, 55, 60, 65
To ensure sustained accuracy at HSK interfaces, we recommend comparison measuring of the geometry of HSK tool shanks and spindles at regular intervals. These checks should become more frequent with an increased change rate at the interface. Calibration on request.
Test arbor for mounting to turning-center and measuring run-out. Designed for either A2-5 and A2-6 lathe face mounting.
TAC Rockford Morse spindle taper gauges are for inspection of Morse spindle tapers. Gauges made from a hardened gauge steel, and include a padded carrying case and certificate. Manufactured per DIN 229.
Non-contact measuring with nozzles results in high accuracy and consistency of measuring results. The measuring range can be increased with the built-in dial indicator. This enables the gauge to be used during pre-machining of the taper. Measuring set with case includes nozzle plug gauge with dial indicator and 2 setting rings.
