Competitor Information for Ammco	Accu-Turn 8922L	Ammco 3850/3860
Easy To Use	Impossible to accidently engage incorrect feed.	Possible to accidently engage incorrect feed.
	One cut finish, regardless of amount of material to be removed.	One pass finish. Only shallow cuts.
	Rotor and drum feeds shut off electrically at end of travel using a limit switch.	No limit switches, feed screws bind up.
Rigid Construction	Cross feeds on massive dove tail ways with 4 adjustment points for wear.	Cross feeds are hung on a round tube with no adjustments for wear. Drum feed is on a small dovetail way.
	Cross slides are stacked on cast iron housings for added rigidy.	Cross slides are hunt with little support.
Durability	Cross feeds and ways are protected by stainless steel way covers.	Cross feeds use rubber boots which are easily damaged & hard to replace.
	Motor for each rotor, drum and spindle.	One motor for rotor and drum feeds.
	Lubricated feed screws with stainless steel protection.	Drum feed screw not protected or lubricated.
Accuracy	Cross feeds are on massive dove tail ways w/ 4 adjustment points for wear.	No adjustment for rotors cross feed.
	Fully machined adapters with strict tolerances trroughout.	Light weight adapters with loose tolerances.
	Positive rake tooling.	3850 positive/3860 neg. rake tooling.
	Exceeds all OEM specifications with only one pass. (Non-directional finishing not required).	Requires additional non-directinal finish to meet OEM specifications.
Versatility	Machines rotors, drums & flywheels.	Machines rotors and drums.
	Accommodates wide range of rotors 4-24" in diameter, up to 2-1/4" thick, standard.	Accommodates rotors up to 21.5" in diameter, up to 1-3/4" thick, standard.
	Machines flywheels with std. equipment.	Does not machine flywheels.

Competitor Information for John Bean	Accu-Turn 8922L	John Bean 601
Easy To Use	Single speed spindle and feed motors.	Two speed spindle with one motor for all operations of lathe (spindle, rotor and drum feeds).
	One cut finish, regardless of amount of material to be removed.	One cut finish. (Shallow depth of cut).
	Rotor and drum feeds turn off eoectrically at end of travel using a limit switch.	No limit switch on rotor feed.
	Rotor feed can be operated at any position. (No arrows to align)	Must align arrows to machine rotors.
Rigid Construction	Cross feeds are on massive dove tail.	Small dovetrails with only one adjustment on rotor side.
	Massive dovetails stacked on cast iron housing for added rigidity.	Small dovetails on side of lathe casting. (Catches debris, causes wear)

Durability	Cross feeds and ways are protected by stainless steel way covers.	Exposed feed screws.
	Simplicity of design; only 6 gears in entire lathe.	Complicated gearbox. (Expensikve to repair).
	Motor for each rotor, drum and spindle.	One motor for all operations of lathe (Spindle, rotor and drim feeds).
	Lubricated feed screws with stainless steel protection.	Exposed feed screw. (Non lubricated)
Accuracy	Adjustable strict tolerances.	Will not maintain factory specifications.
	Fully machined adapters with strict tolerances throughout.	Light weight, 4-way split collet adapters with very little reference area.
	Exceeds all OEM specifications with only one pass. (Non-directional finishing not required).	Requires additional non-directional finish to meet OEM specifications.
Versatility	Accommodates wide range of rotors 4-24" in diameter.	Accommodates range of rotors 6-20" in diameter.
	Machines flywheels with standard equipment.	Need opotional flywheel adapters.
