How much does the Kent CNC CT-1118 cost?
Price estimate
We do not have a price for the Kent CNC CT-1118 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 CT-1118 is a small collet lathe: 11 in (279 mm) of swing over the bed, 18 in (457 mm) between centers, a 5C spindle that runs from 25 to 4,000 rpm and a guaranteed circular accuracy of 50 millionths of an inch (1.3 µm). It weighs 2,200 lb (998 kg) and stands in an 81 x 40 x 65 in (2,057 x 1,016 x 1,651 mm) footprint.
Everything about the spindle points at small, round, accurate parts. Bar capacity is 1.0625 in (27 mm) through a 5C collet, inside a 1.5 in (38 mm) spindle bore. For work too large for a collet, the listed workholding is step chucks up to 6 in (152 mm) in diameter, and the collet closer is either lever or air operated. Power is 3 hp (2.2 kW) as standard with 5 hp (3.7 kW) as an option. Neither rating is meant for heavy stock removal, and the working envelope agrees: X travel is 6.25 in (159 mm), Z travel 13.5 in (343 mm) and swing over the cross slide 6 in (152 mm).
The axes are quick for a machine of this size. X and Z both rapid at 800 in/min (20.3 m/min) on 0.66 hp (0.5 kW) servo motors, well ahead of Kent CNC's larger lathes: the KLS-1840N lists 394 in/min (10 m/min) in Z, and the CRL-1640 295 in/min (7.5 m/min). With only 13.5 in (343 mm) of Z to cover, moves between cuts take very little of the cycle.
A tailstock with an M.T. #2 taper and 3.75 in (95 mm) of quill travel supports longer parts. The control is the Fanuc 0i-Mate TD, with the Fagor 8055i as an option. The coolant pump is 1/8 hp (0.1 kW). Kent CNC's table lists no turret or tool post for this model, so ask how the quoted machine is tooled. Shipping weight is 2,420 lb (1,098 kg).

Strengths & Limitations
Strengths
- Guaranteed circular accuracy of 50 millionths of an inch (1.3 µm)
- 5C spindle running 25-4,000 rpm, with 1.0625 in (27 mm) bar capacity through the collet
- 800 in/min (20.3 m/min) rapids on both X and Z
- Step chucks up to 6 in (152 mm) in diameter and a lever or air-operated power collet closer
- Compact: 81 x 40 x 65 in (2,057 x 1,016 x 1,651 mm) and 2,200 lb (998 kg)
Limitations
- Bar capacity stops at 1.0625 in (27 mm) through the 5C collet
- Standard spindle power is 3 hp (2.2 kW); the 5 hp (3.7 kW) motor is an option
- Z travel is 13.5 in (343 mm) and swing over the cross slide 6 in (152 mm), so long or large-diameter parts are out of range
- The table lists no turret or tool post, so the tooling arrangement has to be confirmed with the seller

Frequently Asked Questions
01
Bar capacity is 1.0625 in (27 mm) through a 5C collet. The spindle bore itself is 1.5 in (38 mm). Larger pieces are held in step chucks, which the table lists up to 6 in (152 mm) in diameter, and swing over the cross slide is 6 in (152 mm).
02
Kent CNC lists a guaranteed circular accuracy of 50 millionths of an inch (1.3 µm). That is the only accuracy figure in the table; it gives no positioning or repeatability values for the axes, so ask for those if the part drawing depends on them.
03
The spindle runs from 25 to 4,000 rpm. The standard motor is 3 hp (2.2 kW) and a 5 hp (3.7 kW) motor is an option. The spindle takes 5C collets, closed by a lever or air-operated power collet closer.
04
They are different classes of lathe. The CT-1118 is a 2,200 lb (998 kg) collet machine with a 4,000 rpm spindle of 3 hp (2.2 kW), or 5 hp (3.7 kW) as an option, and 800 in/min (20.3 m/min) rapids. The CRL-1640 weighs 4,730 lb (2,146 kg), has a 7.5 hp (5.6 kW) spindle to 3,000 rpm with a Camlock D1-6 nose and a 2.066 in (52 mm) bore, and rapids of 295 in/min (7.5 m/min) in Z.
05
Yes. The tailstock has an M.T. #2 taper and 3.75 in (95 mm) of quill travel, and the distance between centers is 18 in (457 mm). Z travel is 13.5 in (343 mm), so that is the length the tool can cover along a part held between centers.
