Price estimate
We do not have a price for the YCM TC-46/1650 that we can stand behind, so we show no number. Configuration, options and installation move the final price a long way: a quote is the reliable figure.
Overview
With 1,650 mm (64.96 in) between chuck and tailstock, the YCM TC-46/1650 is the general-purpose length in YCM's large lathe family. Maximum turning diameter is ø750 mm (ø29.53 in), the chuck is 15" on an A2-11 nose, and the gearhead spindle motor is rated 30/37 kW (40/50 HP).
This length covers the common run of heavy shafts: gearbox shafts, axles, pump rotors, crusher and mill components. The tailstock quill travels 1,475 mm (58.07 in), so it reaches short parts as easily as long ones. YCM clamps the tailstock to the guideways with two cylinders to stop it skidding under load and moves it with a hydraulic connecting bar. The quill is a fixed MT-5 with a live centre as standard; a rotating quill with a dead centre is optional.
The Z axis keeps the 18 m/min (708.66 ipm) rapid of the shorter TC-46/1000, where the two longest beds are slower. X rapid is 16 m/min (629.92 ipm), with the cross slide carried by a hydraulic balance cylinder.
Headstock details are common to the family: ø130 mm (ø5.12 in) through the spindle, ø117 mm (ø4.61 in) through the draw bar, and 1,800 rpm with the standard chuck, falling to 1,600 and 1,200 rpm with the 18" and 21" chucks. The turret is a 10-station servo unit, 12 stations optional. High pressure coolant is supplied for chip removal, and a roof shower is an option. Machine weight is 13,500 kg (29,762 lb).
