How much does the Kent CNC KLS-1840N cost?
Price estimate
We do not have a price for the Kent CNC KLS-1840N 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
The Kent CNC KLS-1840N is a fully covered CNC lathe with an 18 in (457 mm) swing over the bed, 39.4 in (1,001 mm) between centers and a 3 in (76 mm) spindle bore. It is supplied with a 10 in (254 mm) 3-jaw manual chuck, a 4-way electric tool post and the FANUC 0i-Mate TF control.
The bore is the reason to look at this model. At 3 in (76 mm) through a D8 nose with an M.T. #7 taper, it passes pipe, tube and heavy bar that Kent CNC's 16 in lathes cannot: the CRL-1640 has a 2.066 in (52 mm) bore and the CSM-1640 a 2-1/4 in (57 mm) bore. The bed is 13.8 in (351 mm) wide, and the machine weighs 5,236 lb (2,375 kg).
Spindle speed runs from 100 to 2,000 rpm. Standard power is 7.5 hp (5.6 kW), and a 10 hp (7.5 kW) motor is an option worth pricing if the work is mostly large-diameter roughing, since the standard rating is the same as that of the smaller CRL-1640. The 100 rpm floor matters at the top of the swing: a part near 18 in (457 mm) in diameter is already moving quickly at the lowest speed, so check the surface speed your material needs before planning big facing cuts.
X travel is 11 in (279 mm) and Z travel 38 in (965 mm), with 9.84 in (250 mm) of swing over the cross slide. Rapids are 394 in/min (10 m/min) in Z and 315 in/min (8 m/min) in X, driven by FANUC servo motors on both axes. The table gives the X and Z axis motors as 1.13 / 0.6 hp (0.8 / 0.4 kW).
The tool post holds four tools and indexes electrically; a 6-position turret is the option. The chuck is manual, so each part is clamped by hand. Kent CNC states that other CNC options are available in place of the FANUC control. Overall size is 100 x 55 x 67 in (2,540 x 1,397 x 1,702 mm), and shipping weight is 5,720 lb (2,595 kg).

Strengths & Limitations
Strengths
- 3 in (76 mm) spindle bore with a D8 nose and M.T. #7 taper, against 2.066 in (52 mm) on the CRL-1640
- 18 in (457 mm) swing over the bed with 38 in (965 mm) of Z travel and 11 in (279 mm) of X travel
- Supplied with a 10 in (254 mm) 3-jaw manual chuck and a 4-way electric tool post
- Full cover enclosure, with FANUC servo motors on X and Z and the FANUC 0i-Mate TF control
- Rapids of 394 in/min (10 m/min) in Z and 315 in/min (8 m/min) in X, faster than the 295 in/min (7.5 m/min) Z rapid of the CRL-1640
Limitations
- Maximum spindle speed is 2,000 rpm, and the lowest is 100 rpm
- Standard power is 7.5 hp (5.6 kW); the 10 hp (7.5 kW) motor is an option
- The 10 in (254 mm) 3-jaw chuck is manual, so parts are clamped by hand
- The standard tool post has four positions; the 6-position turret is an option
- The table gives no tailstock taper or quill figures for this model

Frequently Asked Questions
01
The spindle bore is 3 in (76 mm), with a D8 spindle nose and an M.T. #7 taper. Among Kent CNC's nearby lathes the CRL-1640 has a 2.066 in (52 mm) bore and the CSM-1640 a 2-1/4 in (57 mm) bore, so the KLS-1840N is the one to choose for larger bar and tube through the headstock.
02
The table lists a 10 in (254 mm) 3-jaw manual chuck, a 4-way electric tool post, a full cover enclosure, FANUC servo motors on the X and Z axes and the FANUC 0i-Mate TF control. The 6-position turret and the 10 hp (7.5 kW) spindle motor are options, and other CNC options are available.
03
The standard spindle motor is 7.5 hp (5.6 kW), and a 10 hp (7.5 kW) motor is optional. Speed runs from 100 to 2,000 rpm. For regular roughing near the 18 in (457 mm) swing, the optional motor is the one to ask about.
04
Swing over the bed is 18 in (457 mm) and swing over the cross slide is 9.84 in (250 mm). Distance between centers is 39.4 in (1,001 mm), with 38 in (965 mm) of Z travel and 11 in (279 mm) of X travel.
05
The machine measures 100 x 55 x 67 in (2,540 x 1,397 x 1,702 mm) and weighs 5,236 lb (2,375 kg). Shipping weight is 5,720 lb (2,595 kg). Allow extra length behind the headstock if long bar will be fed through the 3 in (76 mm) bore.
