We had an early HAAS lath that required a number of service calls. Among these was a spindle failure, meaning a terrible sharp noise on spindle reversal.
Obviously a bearing problem.
The early lathes had a spring loaded collet closer, pneumatically actuated. On our new machine we have a hydraulic closer. This generates more heat but is better otherwise. Also only one turret was available.
The servos were DC brush type, and on our 1993 VF-2 we had trouble with carbon buildup shorting out the controller. We did not keep the lathe long enough to encounter the brush dust problem.
The maximum RS232 baud rate on all HAAS machines was 38.4 kbaud until about 1998.
The worst problem on early HAAS lathes was software bugs in canned cycles.
