The line includes four machines, PJ812, J1220, J1230 and J1625 (specifications below). They provide positioning accuracy and repeatability of ±1 micron. A thermal compensation system employs sensors on the machine faceplate and inside the spindle to minimize the effects of temperature changes on part accuracy and cut temperature-generated displacement by 60%. This system also reduces Z-axis thermal growth and deflection by 30%. Cooling systems for slide way lubrication and ballscrew cores stabilise axis feed precision.
Mechanical design features that maximise machine rigidity and accuracy include hardened and ground tool steel box slideways as well as contact elements that enhance acceleration, reduce stick-slip, and allow for feed accuracy of 0.1 micron. Another proprietary engineering detail drastically improves the static rigidity of the Z-axis to more than six times that of conventional Z-axis arrangements.
These heavy duty, ultra-precision machines allow for more complete machining of precision components, including precision boring, milling, drilling and tapping. They offer machining centre technology and jig borer precision in one machine.
