The Johnford SDMC Series delivers exceptional flexibility and structural integrity for machining the largest and heaviest workpieces. These sliding column, fixed-table bridge mills feature machine weights exceeding 400,000 lbs. and travels up to 30 meters, providing unlimited table load capacity and absolute accuracy across long production runs. Models are available with X-axis travels up to 25,000 mm (984″), and can be configured as 3-Axis, 5-Face, or full 5-Axis machines to match part geometries and complexity requirements. Johnford is known globally for building custom machine configurations to meet specific manufacturing needs.

3-Axis SDMC Bridge Mills

Johnford’s 3-axis SDMC machines are built for large, heavy-duty machining with X, Y, and Z travel only. This configuration provides the greatest simplicity and cost efficiency for shops that don’t require complex angular positioning. With a fixed table and sliding column design, the workpiece stays stationary—making these machines ideal for massive parts with extreme weight or length.

Key Features

X/Y/Z axis configuration with massive travels
Fixed-table, moving-gantry design for unlimited table loads
Meehanite castings with machine weights up to 403,000 lbs.
Ideal for heavy cutting on flat or prismatic parts
ATC system up to 60 tools (expandable)
Optional W-axis for additional vertical clearance

Ideal For

Mold and die bases
Large machine beds or frames
Structural plates and industrial tooling
Shops requiring size, strength, and simplicity

5-Face SDMC Bridge Mills

The 5-face SDMC configuration adds an automatic indexing head for multi-plane machining—enabling access to the top, front, rear, and both sides of a part. This reduces setups, improves part accuracy, and dramatically increases throughput. Johnford’s cradle-stored head design makes head changes automatic and efficient, while maintaining the same SDMC rigidity and table load capacity.

Key Features

5-face automatic head attachment with 90° positioning
Programmable head rotation in 5° increments
Reduces part setups and operator repositioning
Ideal for boxy, structural parts requiring multiple face access
Same fixed-table, sliding column architecture
ATC and chip removal system included

Ideal For

Large equipment housings
Aerospace structures and weldments
Multi-sided mold bases
Shops improving setup efficiency

5-Axis SDMC Bridge Mills

Johnford’s full 5-axis SDMC machines are equipped with a 2-axis continuous contouring head for simultaneous 5-axis machining. Built on the same ultra-rigid sliding gantry platform, these machines are ideal for swept surfaces, angular features, complex contours, and deep cavities. Choose from Johnford’s in-house-designed AC-4 or AC-5 heads for high-performance cutting, depending on your torque, speed, and application requirements.

Key Features

2-axis continuous head for full simultaneous 5-axis control
AC-42 (HSK-63A, 20,000 RPM, 31 HP) for high-speed finishing
AC-52 (HSK-100A, 10,000 RPM, 47 HP) for heavy cutting
Precision angular control across large workpieces
Reduces setups and unlocks complex part geometries
Still built on the same fixed-table, unlimited-load SDMC structure

Ideal For

Aerospace components with compound curves
Precision mold & die machining
Energy-sector and defense parts
High-mix, low-volume production needing full flexibility

No matter which SDMC configuration you choose—3-axis, 5-face, or full 5-axis—each machine is engineered with Johnford’s signature strength, accuracy, and flexibility.
