JTEKT FH630SX

A new JTEKT FH630SX typically runs between $450,000 and $750,000 depending on configuration. A base machine with the 8,000 RPM spindle, 60-tool magazine, and two-pallet changer starts around $450,000. Adding the 15,000 RPM spindle option, expanded tool magazines (up to 330 tools), through-spindle coolant, and probing packages pushes the price to $550,000-$650,000. Fully loaded machines with multi-pallet automation systems can exceed $750,000. Used FH630SX machines from 2015-2020 typically sell for $200,000-$400,000 depending on hours and configuration.

Both are top-tier 630mm HMCs, but they emphasize different strengths. The FH630SX leads on spindle torque (1,088 Nm vs approximately 900 Nm) and positioning accuracy, making it the better choice for heavy-cutting applications in cast iron and steel. The Mazak HCN-8800 counters with Mazak's extensive dealer network, the Mazatrol SmoothG control with conversational programming, and broader automation ecosystem options. The Mazak also offers a wider range of spindle speed options. Both machines hit 60 m/min rapids. Choose the FH630SX for raw cutting power and accuracy; choose the Mazak for ecosystem and programming convenience.

The FH630SX offers two primary spindle options, both using CAT 50 (BT 50) taper. The standard 8,000 RPM spindle delivers 80 kW (107 hp) and 1,088 Nm of torque—ideal for aggressive roughing with large face mills and boring bars. The optional 15,000 RPM spindle delivers 55 kW (74 hp) with reduced torque but significantly higher surface speeds for finishing operations and aluminum machining. Both spindles feature through-spindle coolant capability.

Yes, the FH630SX is designed for automated production. The standard two-pallet changer enables continuous production with offline loading. JTEKT offers expanded multi-pallet systems (4, 6, or more pallets) for higher automation levels. The tool magazine scales to 330 tools for extended unattended runs. The TOYOPUC-Touch control includes pallet scheduling, tool life management, and FMS integration capabilities. Many installations pair the FH630SX with linear pallet pool systems for true lights-out manufacturing.

They are essentially the same machine platform under a different brand name. JTEKT Corporation (which owns the Toyoda machine tool brand) rebranded its North American operations from Toyoda to JTEKT Machinery. The current FH630SX-i designation indicates incremental improvements including updated controls, improved thermal compensation, and enhanced automation interfaces, but the core machine platform—castings, spindle, axis drives—remains the proven Toyoda design that has been refined over decades.

The FH630SX excels at heavy-duty machining of cast iron (gray, ductile, and CGI), carbon and alloy steels, stainless steels, and aluminum. The 1,088 Nm spindle torque allows large-diameter face mills and boring bars to run at optimal chip loads in ferrous materials. The 15,000 RPM spindle option enables high-speed aluminum machining for aerospace and automotive applications. The machine's rigidity and thermal stability also support effective machining of titanium and nickel alloys, though dedicated aerospace HMCs may be preferred for those materials at high volume.
