How much does the Leadwell H-630 cost?
Estimated price range
Our best estimate for a horizontal machining centers (hmc) in this class — not a quote from Leadwell. Configuration moves it a long way.
Overview
The Leadwell H-630 is a horizontal machining center with a 630 x 630 mm pallet (24.8 x 24.8 in), 800 mm (31.5 in) of travel in each of X, Y and Z and a No. 50 taper spindle that runs to 10,000 RPM. The listed figures are unverified: nothing in the table has been confirmed against a Leadwell page.
Equal travel on all three axes gives a cubic work zone larger than the pallet, so a fixture tower can overhang the pallet edges and still be reached on every face. The limit comes from weight before it comes from space. Maximum table load is 750 kg (1,653 lb), and a tombstone with its vises takes a good part of that before any workpiece is loaded.
The spindle pairs a No. 50 (BT50 / CAT50) taper with 10,000 RPM. Big-taper tooling carries large face mills and long boring bars, and the speed keeps smaller cutters productive in aluminium. Power is listed as 22 / 18.5 kW (30 / 25 hp), two ratings the table does not label, and no torque figure is given. Whether BT50 or CAT50 is fitted has to be read from the machine.
The magazine is a chain-type ATC with 60 tools, with 90 and 120 tool options. Maximum feed rate is 40,000 mm/min (1,575 ipm). The control is a Fanuc 31iMB, and the machine weighs approx. 22,000 kg (48,500 lb).

Strengths & Limitations
Strengths
- 800 mm (31.5 in) of travel in X, Y and Z around a 630 x 630 mm pallet (24.8 x 24.8 in)
- No. 50 (BT50 / CAT50) taper spindle with a 10,000 RPM top speed
- 60 tools in a chain-type ATC, with 90 and 120 tool options
- Maximum feed rate of 40,000 mm/min (1,575 ipm)
Limitations
- Maximum table load is 750 kg (1,653 lb), which a loaded tombstone approaches quickly
- Spindle power is given as 22 / 18.5 kW (30 / 25 hp) without saying what each rating refers to, and no torque is listed
- Machine weight of approx. 22,000 kg (48,500 lb) needs a suitable floor and rigging

Frequently Asked Questions
01
Travels are 800 mm (31.5 in) in X, 800 mm (31.5 in) in Y and 800 mm (31.5 in) in Z. The pallet is 630 x 630 mm (24.8 x 24.8 in). The table does not list the maximum workpiece diameter or height that can swing on the pallet, so ask for the interference drawing before designing a fixture.
02
Maximum table load is listed as 750 kg (1,653 lb). That figure has to cover the tombstone or fixture, the workholding and the parts together. It is an unverified figure, so confirm it on the machine's data plate before planning heavy castings.
03
A No. 50 taper spindle, given as BT50 / CAT50, with a maximum speed of 10,000 RPM. Power is listed as 22 / 18.5 kW (30 / 25 hp). The table does not explain the two power ratings and gives no torque, so request the spindle power and torque diagram.
04
The tool changer row lists 60 tools in a chain-type ATC, with 90 and 120 tool options. Maximum tool diameter, length and weight are not listed. A machine on offer may have any of the three magazine sizes, so count the pockets.
