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.
