Leadwell H-630

The Leadwell H-630 is a 630mm pallet horizontal machining center designed for production shops requiring high-volume, multi-sided part machining in a compact, industrial platform. As Leadwell's flagship horizontal machining center, the H-630 addresses the full range of prismatic production work — from medium-batch automotive components to aerospace structural parts — where the productivity gains of horizontal spindle orientation and 4-sided pallet machining justify the investment over a vertical platform.

The H-630 uses a moving-column architecture with the pallet fixed on a rotary B-axis table, enabling full 4-sided machining in a single setup without repositioning the workpiece. The 630 x 630 mm pallet accommodates tombstone-style workholding for batch production of smaller parts, or dedicated fixture setups for medium-to-large prismatic components. Maximum pallet load is 750 kg, supporting dense steel and cast iron fixture assemblies. The B-axis table indexes in 1-degree increments as standard, with optional 0.001-degree contouring for simultaneous 4-axis work.

The horizontal spindle runs to 10,000 RPM with 22 kW of continuous power through a BT50 taper, providing the high torque necessary for productive steel and cast iron removal on a horizontal platform. Through-spindle coolant is optionally available to support deep-hole drilling and hard-material applications. A 60-tool chain-type ATC is standard, with options to expand to 90 or 120 tools — tool capacities appropriate for complex prismatic parts requiring large tool libraries or lights-out unmanned production.

A 2-pallet automatic pallet changer (APC) is standard, allowing operators to load the next workpiece while the machine cuts, maximizing spindle utilization. Multi-pallet pool options are available for integration into automated manufacturing cells. The machine ships with Fanuc 31iMB control, which supports the full range of horizontal machining center capabilities including advanced interpolation, 5-axis option paths, and integration with pallet management and DNC systems.

The Leadwell H-630 competes with the Doosan HM-630, Hyundai WIA HS-630, and Mazak HCN-6300 in the 630mm HMC segment. Leadwell's Taiwanese manufacturing cost structure positions the H-630 at a meaningful price advantage versus Japanese alternatives at comparable specifications. Typical street pricing runs from $350,000 to $500,000 depending on pallet pool configuration, tooling system, and optional features. For production shops seeking a capable 630mm horizontal machining center with competitive Asian pricing and Fanuc control, the H-630 provides a proven platform for high-volume prismatic work.
