The MT4 Lathe Alignment Test Bar is a precision-engineered inspection and calibration tool designed to verify and correct the alignment between a lathe's headstock and tailstock. Manufactured from premium EN31 alloy steel, this test bar is hardened, ground, and finished to provide exceptional accuracy and long-term dimensional stability.
Designed for direct use in Morse Taper 4 (MT4) spindles, the test bar helps identify alignment errors that can cause unwanted taper when machining long workpieces. It is also ideal for checking spindle accuracy, machine condition, and alignment between centers.
With a maximum run-out of just 0.0002", this test bar is an essential tool for machinists, toolrooms, machine maintenance departments, and precision engineering workshops.
