How much does the Hartford HSA-528EAY cost?
Price estimate
We do not have a price for the Hartford HSA-528EAY 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
With a 5,000 x 2,500 mm (196.9 x 98.4 in) table for 20,000 kg (44,092 lb) and 3,600 mm (141.7 in) of Y travel, the Hartford HSA-528EAY is a five-metre five-face machine built for heavy parts that need work on every side. X travel is 5,000 mm (196.9 in).
Hartford's five-metre 2,500 mm table is offered with four different Y travels. The HSA-528EA has 2,800 mm (110.2 in) and the HSA-532EA 3,200 mm (126.0 in). This model follows at 3,600 mm, and the HSA-532EAY tops the group with 4,000 mm (157.5 in). All four are rated at 20,000 kg, so the buyer is choosing head clearance and nothing else.
The 528EAY is also covered by Hartford's statement that Y-axis ballscrew support is standard on the x28 EAY models. The HSA-528EA does not appear in that list.
Its spec table names a hybrid built-in spindle at 10,000 rpm next to the #50 gear head, which runs 6,000 rpm or optionally 8,000 rpm. Hartford's description adds DDS as a spindle choice and states that the self-made spindle deflects within 5 μm. Z travel is 1,000 mm, or 1,200 mm as an option, and the magazine holds 32, 40 or 60 tools.

- 3,600 mm (141.7 in) of Y travel for angular head clearance
- Y-axis ballscrew support is standard on x28 EAY models
- Hybrid built-in spindle at 10,000 rpm or gear head at 6,000 rpm
Limitations
