2.1 HAAS BAR FEEDER - NGC Installation

The Haas Bar Feeder is for ST10/15/20/25/30/35 and DS-30 lathes.

It is not for ST-30/35 or DS-30 lathes with a gearbox.

This procedure tells you how to install a bar feeder that was made after June, 2017. If you have CHC machine please follow the procedure below.

Press [POWER OFF] on the lathe.

Set the main circuit breaker to the OFF position.

Lock the main circuit breaker. Use an approved lock with an approved safety tag.

If the lathe is an ST-35, or if the machine was made before 11/1/2015, install the coolant collector extension [1] onto the lathe.

Attach the spindle liner adapter [2] to the spindle. Refer to Lathe - Extruded Spindle Liner - Adaptor Kit - Installation. If the lathe is an ST-35, refer to Lathe - ST-30/30Y Big Bore, ST-35/35Y - Spindle Liner Kit - Installation.

Put the bar feeder adjacent to the lathe.

Make sure the frame ends [1] are parallel to the front [2] of the lathe.

Remove the shipping brackets [3] from the frame of the bar feeder.

Remove shipping bolts [1] from both sides of the bar feeder. 

Pull the bar feeder [1] forward until it locks into position.

Find the end of the bar feeder [2].

If the lathe is an ST-35, find the end of the coolant-collector extension [3].

If the lathe is an ST-10, ST-15, ST-20, ST-25, ST-30, or DS-30, find the edge of the coolant collector.

Make sure that the space [4] between them is approximately 0.50" (13 mm).

Warning: If this distance is set incorrectly the first push of a new bar goes past the initial push length location or when pressing Advance Bar [F3], this pushes the bar past the end of the spindle face. Adjust Parameter 602 by the difference of this distance. Length unit is mm.

Find the (4) height adjustment screws [1].

Turn the screws [3] until the frame is 2.0" (51 mm) [2] above the floor [4].
