CU 325
⇔ Lathes for Height of centers 165mm
⇔ Manufacturer: ZMM.
⇔ Origin: Bulgari.
THE ADVANTAGES:
BED:
Heavy, highly ribbed, and rigid bed casting made of strong gray cast-iron which prevents any vibrations when the machine is properly leveled and operated.
Double prismatic, induction hardened and precisely grinded guide ways
Built-in gap bridge which might be removed for processing large work pieces.
HEADSTOCK:
The stable, properly ribbed and precisely processed headstock casting provides a non-vibrating and accurate operation while lathe process parts in high speed or during heavy duty machining regime.
The grinded gears are made of induction hardenedcase-hardening steel and they are working in an oil bath.
The spindle is hardened, precisely grinded and balanced; it has a standard version of the hole and the spindle face, including Cam lock performance, direct mounting of 3-jaw self-centered, 4-jaw independent chucks, face plates without jaws or fastening of the chucks with flange connector.
The spindle bearings may use bearings from SKF, FAG, NSK with bearing set assembling preload. This bearing provides high accuracy of the machine’s work for an indefinite period of time.
LATHE APRON:
Mechanized transverse and longitudinal movements.
A built-in safety mechanism against overloading.
A locking device against simultaneous switching of the nut to the lead screw and automatic feeding.
Quick moves in both axes.

A locking device against simultaneous switching of the nut to the lead screw and automatic feeding.
Quick moves in both axes.
FEED GEARBOX:
When processing a certain part, the feed gearbox provides various feedings and steps for threading – metric, inch, module, and DP threads. It is designed in such a way that its control is primarily convenient.
