Nexturn NST67

Q: How much does the Nexturn NST67 cost?

The price estimate for the Nexturn NST67 is uncertain: we have no price for it that we can cite and no estimate we can stand behind, so we give no figure. Configuration, tooling, automation and installation move the final price substantially. A specific price can be requested at https://machinetoolindex.com/machines/nexturn-nst67#price; the request is passed to Nexturn or an authorised dealer.

Uncertain

We do not have a price for the Nexturn NST67 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

No Nexturn machine takes a larger bar than the NST67: 67 mm (2.6 in). It is the top of the NST family of three-path automatic lathes, with a 12 station turret, a gang type tool post, a sub spindle, a 150 mm (5.9 in) turning length and a FANUC 31i-B control.

Mechanically it is the NST56 opened up for bigger stock. The two columns in Nexturn's table differ only in bar diameter. Main spindle motor, 11 / 15 kW (14.8 / 20.1 hp); sub spindle motor, 3.7 / 5.5 kW (5.0 / 7.4 hp); top speed, 5,000 rpm; weight, 6,400 kg (14,109 lb): all are shared. So the larger bar is cut with the same power, and at full diameter the NST67 will need lighter cuts or lower surface speeds than its sibling.

The proportions of the work change too. With 67 mm of diameter and 150 mm of length the typical part is short and wide, and more of the machining moves to the face and the bore. The main spindle drills to 20 mm (0.8 in) and taps to M16 on centre. Turret live tools and the gang post's cross tools reach 16 mm (0.6 in) and M12 at up to 6,000 rpm, and the largest cross disc mill is 50 mm (2.0 in), which will not span the bar.

Seven back-end tools, four fixed and three live, complete the part on the sub spindle, with back-end drilling to 13 mm (0.5 in). The turret's bore diameter is given as 45 mm. Supply is 45 kVA, coolant capacity 450 L, and rapid traverse on the Y axes 24 m/min.

Strengths & Limitations

Strengths

67 mm (2.6 in) bar capacity, the largest Nexturn lists
12 station turret, gang tool post and back working station under three-path control
Live tooling at all 12 turret stations at up to 6,000 rpm
Built-in main spindle motor with hydraulic disc brake and oil cooling
Same 6,400 kg (14,109 lb) machine as the NST56, so capacity rises without added weight

Limitations

11 / 15 kW (14.8 / 20.1 hp) main spindle is unchanged from the NST56 despite the larger bar
Cross disc mill is limited to 50 mm (2.0 in), less than the bar diameter
Only 150 mm (5.9 in) of turning length
Sub spindle motor is 3.7 / 5.5 kW (5.0 / 7.4 hp), a fraction of the main spindle's rating

Best For

Short, large-diameter parts from bar up to 67 mm (2.6 in) Flanged fittings, bodies and hubs within 150 mm (5.9 in) of length Parts that combine turning with face and cross milling in one cycle Shops moving chucker work onto a bar-fed machine

Frequently Asked Questions

01 What is the maximum bar size of the NST67?

67 mm (2.6 in), with a maximum turning length of 150 mm (5.9 in). On-centre drilling is listed at 20 mm (0.8 in) and tapping at M16. Nexturn gives the bar remnant for the NST family as less than 80 mm.

02 Does the NST67 have more power than the NST56?

No. Both list an 11 / 15 kW (14.8 / 20.1 hp) main spindle and a 3.7 / 5.5 kW (5.0 / 7.4 hp) sub spindle at up to 5,000 rpm. The NST67 only adds bar capacity, 67 mm (2.6 in) against the 56 mm (2.2 in) of the NST56.

03 What tools does the NST67 carry?

Four OD tools and four cross live tools on the front gang post, 12 turret stations that all accept live tools, and seven back-end face tools. Turning tools use □20 × 125 mm (0.8 × 4.9 in) shanks. Nexturn puts the maximum at 39 tools mounted.

04 What services does the NST67 need?

Power consumption is listed at 45 kVA. The coolant tank holds 450 L, served by two 0.9 kW pumps, with a 2 L lubrication tank and 12 L of cooling oil. Machine weight is 6,400 kg (14,109 lb). Overall dimensions are not among the listed figures, so request a layout drawing.
