Hartford PBM-135A

Q: How much does the Hartford PBM-135A cost?

The price estimate for the Hartford PBM-135A 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-pbm-135a#price; the request is passed to Hartford or an authorised dealer.

Uncertain

We do not have a price for the Hartford PBM-135A 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

Hartford's PBM-135A is the first of three PBM-135 horizontal boring mills, and the one with the smallest table: 1,400 x 1,600 mm (55.1 x 63.0 in) for 8,000 kg (17,637 lb). What it gains over the PBM-115A is everything around that table.

Travels are listed with options. X is 2,500 mm, with 3,000 mm or 4,000 mm available. Y is 2,000 mm, optionally 2,500 mm, and Z is 1,500 mm, optionally 2,000 mm. The W axis is 700 mm (27.6 in). A buyer therefore specifies the machine around the largest part: the same table can sit under a 4,000 mm X stroke if long weldments have to be machined end to end.

The spindle stock is the heavier one of the PBM range. Hartford quotes a 4-step speed change and a spindle torque of 6494N/m with the 37kw motor, and says the spindle is carried in D4 class bearings. Top speed is 2,500 rpm on a #50 nose. The listed motor is 22 / 26 kW, with 30 / 37 kW as the option (Cont. / 30 min).

Column and base are scaled up as well: 780mm between the column's box guideways, each 100mm thick, and 1140mm between the base guideways. The magazine holds 32, 40 or 60 BT-50 tools.
