What fits a Haas ST-45
Each of these follows from a published specification above, which is named beside it.
Workholding
An 18-inch chuck. Jaw sets, soft jaws and collet chucks for this size are commodity items, but the chuck itself, and any spare jaws, travel with the machine and are counted in an offer.
Derived from Chuck size: 18.0 in
Bar feeder fit
Bar capacity is 6.5 in, so a bar feeder for this machine has to be sized for stock up to that diameter. A feeder that comes with the machine is one of the accessories that most changes what a buyer will pay for it.
Derived from Bar capacity: 6.50 in
What to check on a Haas ST-45
- Control generation. The manufacturer specifies Haas Control for this model. Units we have tracked run 2014 to 2023; an early one may carry an older control or a retrofit.
- Spindle. The manufacturer gives a spindle speed of 1400 rpm. Run the spindle to top speed and listen for bearing noise.
- Axes and way covers. The manufacturer gives X 20.00 in and Z 44.00 in of travel. Run each axis end to end and check the way covers.
- Turret. The manufacturer gives the turret stations as 12-Station BOT. Index every station and time a full turn.
