How much does the Litz LH-630B cost?
Price estimate
We do not have a price for the Litz LH-630B 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
The Litz LH-630B is the 50-taper machine among the 630 mm LH horizontal machining centers. It has a No.50 spindle at 6,000 rpm, belt type transmission, and travels of 1,000 mm (39.4 in), 850 mm (33.5 in) and 950 mm (37.4 in) in X, Y and Z.
Belt drive sets it apart from the direct-drive LH-630A. A belted spindle isolates the motor from cutting vibration and heat, and it is the usual arrangement for 50-taper spindles that spend their life boring and face milling. The front bearing bore is 100 mm (3.9 in).
Torque is listed at 165 Nm (122 lb-ft) with a 22 / 26 kW (29.5 / 34.9 hp) motor. That is moderate for the taper. The larger LH-800B, by comparison, reaches 660 Nm through a ZF gear box. Treat the LH-630B as a machine for cast iron, aluminium and medium steel cuts with big tools, and look further up the range for heavy steel roughing.
Tools can weigh 20 kg (44 lb) and measure 450 mm (17.7 in) in length, 120 mm (4.7 in) in diameter with neighbours and 230 mm (9.1 in) without. The magazine holds 40 with fixed address selection. Pallets are 630 x 630 mm (24.8 x 24.8 in) with a 1,000 kg (2,205 lb) rating, changed by a rotary changer in 18 s. Rapids are 32,000 mm/min (1,260 ipm). Weight is 23,000 kg (50,705 lb) and supply 42 kVA.
