Descriptions    

Bed: The bed is a one piece "L" shaped casting. 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 Romi "L" shaped design creates a rigid base fully supporting the headstock. The slant bed design provides good chip fall into the roll out chip pan or roll out chip conveyor.

Guide Ways

Guide ways: The Z-axis moves on the slant bed which has an oversize inverted vee way and a rectangular way. This design has been used on precision grinding machines for many years. Romi's patented manufacturing process grinds all way surfaces in one set up for maximum machine accuracy. The Romi guide way and carriage system permits heavy cutting in both the clockwise and the counter clockwise direction. .063" Turcite on the underside of the carriage ensures minimum friction and long life. The carriage guide ways are a precision ground dovetail system with one gib on the side away from the headstock. The bed ways and ball screws are isolated from chips and coolant by one stainless steel cover on each side of the carriage. Romi's machine design is ideal for heavy stock removal using either clockwise or counter-clockwise turning.

Headstock: The Romi 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". Additionally, the thermal pads isolate any 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

Carriage and Turret: The carriage is a rugged 20 degree casting with a wide stance to eliminate any twisting due to cutting forces. The oversize vee guide way provides straight movement through the entire Z axis travel without gib adjustment. .063" thick turcite is scraped and fitted to the underside of the carriage to eliminate friction in the Z axis. The X axis moves on a dovetail guide system. 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. The tool holders 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 insured. We are 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 travels on vertically mounted, precision ground, inverted vee and square ways. The body is positioned automatically over 32.87 inches and the quill is controlled by either program or push button. Quill travel is 5.1 inches and the quill is 3.94 inches in diameter with a 4 MT.

Lubrication: Automatic lubrication is standard. The lubrication reservoir is located in a protected inset in the front of the machine's sheet metal guarding. It is in plain sight and easy to refill, but It is protected from accidental damage. 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 is a one piece stainless steel guard to guide chips and coolant into the chip conveyor. No accordion guards are used. 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 large safety window allows the operator to monitor machine operations.
