Hartford spindle and motor spindle repair
Brochexpress is an independent workshop specialising in the repair, maintenance and diagnostics of Hartford spindles and motor spindles — the Taiwanese leader in quality machining centres, with a range covering vertical, horizontal, double-column and gantry machines.
Hartford, the Taiwanese leader in machining centres
TLDR: Hartford Machinery (Taiwan) positions itself as the Taiwanese leader in quality machining centres, with a full range of vertical and horizontal CNC machining centres, large vertical centres, as well as gantry centres and boring mills.
Hartford Machinery has established itself as the Taiwanese leader in quality machining centres, with a range covering vertical and horizontal CNC machining centres, large vertical machining centres, as well as gantry centres and boring mills. The LG series, dedicated to compact and mid-size vertical configurations, together with the PRW series, a double-column design for large and heavy parts (up to 15 tonnes on the table), illustrate the breadth of the range. HSA centres, with a very large table (up to 6,000 x 2,200 mm), complete the offering for machining exceptionally large parts.
A range of robust spindles, from the compact centre to the large double-column machine
TLDR: Hartford machining centres use BT-40 or BT-50 (SK50/DIN 69871) taper spindles, with rotation speeds typically from 6,000 to 8,000 rpm on standard configurations, reaching up to 20,000 rpm as an option on high-speed models.
Hartford vertical machining centres (LG series, VMC) use BT-40 or BT-50 taper spindles, with main motor power of around 15 kW and rotation speeds typically of 8,000 rpm, for a tool magazine of 20 to 32 stations depending on the configuration. On PRW series double-column machining centres, dedicated to massive parts, the SK 50 taper spindle (DIN 69871A) typically runs at 6,000 rpm, with a tool magazine of up to 60 stations. On the high-speed centres in the range, spindles can reach 20,000 rpm for high-speed machining of moulds and precision parts.
