JOHNFORD - ROUNDTOP MACHINERY COMPANY HMC-630 HORIZONTAL MACHINING CENTER

The Johnford HMC-630 Horizontal Machining Center is a high-rigidity CNC machine designed for heavy cutting and precision machining. It features a horizontal spindle with a #40 taper standard, optionally upgraded to #50, capable of reaching 15,000 RPM (10,000 RPM optional), driven by a 50 HP motor rated for 30 minutes. The worktable measures 24.8" by 31.5", supporting a maximum workpiece weight of 2,640 lbs, suitable for robust industrial applications. Its 4-axis configuration includes linear travels of 40" (X), 32" (Y), and 35" (Z), along with full 360° B-axis rotation, enabling complex contouring and multi-face machining. The machine uses an Automatic Tool Changer (ATC) with a capacity of 60 tools, expandable to 120, enhancing flexibility and reducing downtime during production. It offers rapid and precise positioning capabilities with advanced linear guides to ensure stability and accuracy under heavy cutting loads. This machining center’s solid construction, including a T-shaped frame and reinforced column design, minimizes chatter and distortion, thereby facilitating high torque output across a wide speed range. Its tooling and feed systems are optimized for heavy-duty parts manufacturing in automotive, aerospace, and mold industries, providing a blend of productivity, versatility, and reliability for precision horizontal machining tasks.
