Product Description:

The OSP-700L is a numerical control monitor produced by Okuma within the OSP CNC Monitors series. Designed for lathes and compact machining cells, the unit combines display, input, and axis-control electronics in one panel for shop-floor automation. It supervises programmed tool paths, reports position feedback, and transmits speed and feed commands to the machine tool’s servo drives and spindle inverter. Through its integrated tape interface and local memory, it executes part programs without external computing hardware.

The controller manages simultaneous X/Z 2-axis motion, allowing concurrent interpolation of the primary slide and carriage. Operator feedback appears on a 9-inch monochrome STN screen that provides clear textual status and tool data. Feed velocity can be trimmed because the override knob spans 0 to 200%, enabling real-time slowdowns during gauging or full-speed dry runs. Incremental data entry follows inch standards down to 0.0001 in, making fine adjustments straightforward. For contour generation, the control offers linear and circular interpolation, and its internal memory holds up to 24,000 characters of G-code. Programs may use ISO (R840) or EIA (RS-244A) formats, manual pulse input can be scaled by ×1, ×10, or ×50, absolute encoders eliminate homing cycles, and a four-digit S word sets spindle speed that can be varied between 50 and 200% with the override switch.

External communication is handled through a RS-232C port, facilitating drip-feed of large files or diagnostic data between the control and a host computer. When metric programming is required, axis commands resolve to 1 µm steps, matching fine-pitch ballscrews used on precision machines. For long part programs, the built-in reader scans punched tape at 270 characters per second, accepts rolls up to 60 m, and stores tool offsets for 32 cutter-geometry pairs. Pulse magnification choices and absolute feedback preserve position accuracy when the machine switches between manual and automatic modes.
