ZMM Conventional Lathes

ZMM offer European quality at affordable prices, with over 70 years of experience in manufacturing, over 115,000 lathes made to date, sold to over 80 countries, ZMM have a global reputation for producing reliable, high-performance lathes. Over recent years ZMM have produced and introduced a wide range of universal lathes to the international market with turning diameters up to 1410mm and lengths up to 10m.

​

ZMM centre lathes have diverse features and accessories to meet the needs of clients in various industries and geographical locations. Standard on every machine are metric, inch, module and diametrical pitch threads, distance between centers varies between 500mm and 10,000mm and center height between 165mm and 705mm. Their lathes are affordable, rugged, reliable and easy to operate. They are built to last and are known for consistent performance and durability even under the most demanding work conditions are executed to meet and keep with the international safety standards.

 

Most conventional models are also available with infinitely variable speed spindles; on these models the speed control is infinitely variable through the use of a frequency inverter. It is possible to provide a “Continuous cutting speed” (V-const), i.e. the cutting speed is maintained during a change in the turning diameter, thus achieving higher precision and smoothness of the surface.

​

The ADVANTAGES are:

​

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 and a built-in gap which can 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 ground gears are made of induction hardened case-hardening steel and they are worked in an oil bath.
The spindle is hardened, precisely gound and balanced, the spindle bearings are from SKF, FAG, NSK with bearing set assembling preload. This bearings provide 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. Rapid traverse in both axes.

​

FEED GEARBOX: When processing parts, the feed gearbox provides various feeds and steps for threading – metric, inch, module, and DP threads. It is designed in such a way that its control is simple to use.
