LC / SCM Series
The Johnford LC/SCM series is a large, heavy duty, high precision flat bed CNC turning center. The precision spindle structure is supported by precision double row cylindrical roller bearings or high precision taper roller bearings. The bed is a one piece floor to floor Meehanite casting and provides efficient free flow of chips and ease of operator accessibility. The bed has with 3 ways for the ability to turn through the steady rest. The center way on the bed is actually two ways in one and is shared by both the cross slide and the steady rests or other equipment mounted on the back ways. Due to the length of the machine, the Z axis ballscrew is stationary and the ball nut rotates. This eliminates screw whip and vibration. A massive automatic vertical 12 tool turret with a 12” thick tool disk provides fast indexing, as well as coolant through the tool holders. The turret has boring bar capacity of up to 6”. Other turrets and configuration are available including front and rear turrets. The machine is well equipped with the coolant system, work light, 3 jaw hydraulic chuck or 4 jaw manual independent chuck, dual chain type chip conveyors, programmable tailstock with live quill, and the safety guarding as standard accessory.

GMC Series
The Johnford GMC series is a combination of speed, rigidity and precision heavy duty gantry type machining center. The machine design features a moving bridge on two platforms and fixed table for unlimited table loads. The main structures of machine are constructed with Meehanite cast iron. Starting at 3 meters of X travel, the GMC series can be expanded up to 20 meters of X travel. This machine can also be equipped with linear motors or preloaded rack & pinion drives to expand the distance of what you want in X travel. The CNC synchronizes the servo motors to eliminate the crabbing effect. Twin Heidenhain glass scales are standard on the X axis to enhance positioning accuracy. There are two types of bridges. One is a Box-in-Box bridge, and the other is rugged bridge with offset Y-axis ways. The lightweight box-in-box bridge supports the headstock with two additional rugged I-beams. But the rugged bridge with offset Y-axis ways and the traveling head have been designed with diagonally arranged ribs that will help reduce the amount of distortion that is caused by years of continued service. Similarly, all types of bridges can be equipped with linear scales for Y-axis moving precision.
We offer the following:
