JTEKT vs Okuma · Horizontal Machining Centers
Summary
The JTEKT FH630SX and the Okuma MA-12500H are both 50-taper horizontal machining centers, but they are sized for different parts. The JTEKT FH630SX works on a 24.8" x 24.8" (630 mm x 630 mm) pallet; the Okuma MA-12500H carries a 1,250 × 1,250 mm (49.21 × 49.21 in) pallet. The makers publish few comparable figures for this pair, so the table stops at pallet, taper and tool capacity.
On tools, the JTEKT FH630SX comes with 60 as standard and is available with up to 330. The Okuma MA-12500H starts at 81, with 129 and 177 listed as alternative magazine sizes. The spindle tapers are the same size: CAT50 on the JTEKT and No. 50 on the Okuma.

Choose by part size. The JTEKT FH630SX is for housings, cases and blocks that fit a 630 mm x 630 mm pallet, in production or mixed job-shop work, with a magazine that can grow to 330 tools. The Okuma MA-12500H is for large prismatic parts that need a 1,250 × 1,250 mm (49.21 × 49.21 in) pallet and long tool lists from 81 tools upward. With three published rows to compare, the pallet decides.
