Descriptions

Bed: The bed is a one piece (monobloc), "torque tube" design. The casting is poured in our own foundry to DIN 1691 standards. Our foundry is ISO 9002 certified and has been since 1994. The bed casting is heavily ribbed and provides excellent vibration dampening. The slant bed design provides good chip fall into the roll out chip pan or roll out chip conveyor. Romi's universal design means that all E 280 configurations share a common bed which shortens delivery time.

Guide ways: European heavy duty linear guide ball ways are used for speed and accuracy. The bed guide ways are at a 45 degree angle to maintain minimal distance from the cutting area. High acceleration and deceleration rates of up to .7 G's are possible on all axes.

Headstock: The Romi wide stance headstock design anchors the spindle on thermal pads on both sides of the headstock. The headstock support casting is relieved directly under the spindle. As the spindle warms during startup it grows down as well as up. The maximum center line displacement is less than .0003". Thermal pads are used to isolate any source of heat from the rest of the machine structure. Spindle bearings are P4 (AFBMA-B7) double angular contact ball bearings and double row cylindrical roller bearings in front and P4 double roller bearings at the rear of the spindle.

Carriage and Turret: The carriage is a heavy duty casting with a wide stance to eliminate any twisting due to cutting forces. The X axis moves on linear guides driven by a centralized ball screw. Turret index is bidirectional, no rise, non-stop. The turret is driven by an electric servo motor and hydraulically clamped on a curvic type coupling. The turret disc is designed for mounting I.D. or O.D. tools in any station. A VDI 30 tooling disc is also available. The tool holders both live and static are bolt-on so that the tool disc will not need to be replaced when a crash occurs. The turret disc and body are designed to give way under the stress generated in an accident, preventing damage to the spindle, ball screws, etc.

Ball Screws: Ball screws are manufactured and ground by Romi where complete control over the accuracy and quality is assured. Romi is not dependent on commercially available products. The double ball nuts are large in width and diameter. The double nut design provides positive location by mating with both flanks of the screw at all times. This design also minimizes heat distortion. Thermal gauging or temperature reduction systems are not required. The Z axis ball screw is set nearer to rear way to put it at the center of the carriage. Both ball screws are anchored at both ends and directly mounted to the A.C. servos. No problematic clutches are used to weaken the connection. The X axis is pre-tensioned using P4 angular contact ball bearings.

Tailstock: The tailstock body and fixed quill are positioned hydraulically on wide stance linear guideways. The quill is available with a built in, but easily replaceable, center for heavy stock removal or heavier parts or a removable center for machining thin wall parts at high speeds. Quill is a 4 Morse taper.

Lubrication: Automatic lubrication is standard. The reservoir has 1/2 gallon capacity.

Guarding: Romi uses 10 gauge, powder coated steel for all external guarding. In the back of the machining area there are a stainless steel guards to guide chips and coolant into the chip pan or chip conveyor. The door is easy to open and close gliding on multiple rollers. The double overlapping seal ensures that coolant remains in the cutting area, not on your floor. A multi-layered polycarbonate and glass safety window allows the operator to monitor machine operations in safety.
