Hartford SW-426

Q: How much does the Hartford SW-426 cost?

The price estimate for the Hartford SW-426 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/hartford-sw-426#price; the request is passed to Hartford or an authorised dealer.

Overview

The Hartford SW-426 carries 13,500 kg (29,762 lb) on a 4,000 x 2,500 mm (157.5 x 98.4 in) table. It is a box-guideway double-column machining center with 4,000 mm (157.5 in) of X travel and 2,600 mm (102.4 in) of Y.

Hartford's page for this model puts the emphasis on three things under one heading: its gibs, its self-made gear-driven spindle head and the use of angular heads. The gibs deserve a word. A box way is adjusted for clearance by a tapered gib, and on the SW machines that gib is lubricated directly, with double gibs on X and Y. Direct feed keeps oil at the sliding face and off the outside of the casting, which protects the Turcite-B lining from running dry.

The gear head is listed at 4,000 / 6,000 rpm. A #50 DDS spindle at 10,000 / 12,000 rpm is the alternative for finishing. Motors run from 15/18.5 kW through 18.5/22 kW and 22/26 kW to 30/37 kW (Cont. / 30 min).

Z travel is 780 mm, with 1,070 mm as the option. The tool changer is either an S type, listed as S: 20, or an arm type with 32 tools, or 40. The shank is BT-50; BBT-50, CAT-50 and DIN69871A are alternatives.

Frequently Asked Questions

01 What is the capacity of the Hartford SW-426?

The table is 4,000 x 2,500 mm (157.5 x 98.4 in) with an average load of 13,500 kg (29,762 lb). Travels are 4,000 mm (157.5 in) in X, 2,600 mm (102.4 in) in Y and 780 mm in Z, or 1,070 mm optionally.

02 How are the box ways of the SW-426 lubricated?

Through the taper gibs. Hartford states that taper gib lubrication prevents oil leaking from the contact surface between casting and gibs and avoids lubrication failure on the Turcite-B, and that double gibs on the X and Y axis improve machining accuracy.

03 What spindle options does the SW-426 have?

A #50 gear spindle at 4,000 / 6,000 rpm or a #50 DDS spindle at 10,000 / 12,000 rpm. The motor is 15/18.5 kW with 18.5/22 kW, 22/26 kW and 30/37 kW as options.

04 SW-426 or SW-423?

The SW-423 has a 4,000 x 2,200 mm (157.5 x 86.6 in) table, 2,300 mm (90.6 in) of Y travel and a 12,000 kg (26,455 lb) load. The SW-426 is wider and carries more; spindles and motors are the same.
