5.2. Specification of Functional Assemblies of Lathe (Fig. 5.1)
Suitable arrangement of functional assemblies of lathe is the basic presumption for efficient and
safe application of the machine. Description of single units is well - arranged with the aim to make
the orientation easy for service and maintenance on the basic of unified terminology.
Appopriate source of danger resulting from inconsistency of the operator is mentioned by „CAUTION“.
Warning:
The following terminology has been used in this Manual:
- left and right (e.g. left hand side of bed).
- front and rear (e.g. front side of headstock).
- up and down (e.g. lever should be shift up).
The orientation is assumed from the operator place.
5.2.1.
Bed
The bed is designed as a supporting part of lathe and is fitted with a pair of external guideways of carriage and a pair of
internal guideways of tailstock. In both cases one guideway is flat and the other is V - guide. Both ways are hardened.
Hardened ways from cast iron make the longitudinal movement of saddle and tailstock possible. The working accuracy
even if for workpieces of max. mass is ensured by machine rigidity.
Outlet holes in bed allow continuons flow of chips and cutting lubricant from the space of tailstock guidways into a chip
pan.
The bed is fitted with casted tooth system in the internal part under the tailstock guideway which serves for tailstock locking
against its movement in the longitudinal direction. A rack (racks) is bolted down on the front bed side under the carriage
guideway which makes carriage movement(l

5000 mm) and tailstock travel possible. The bottom part of bed is fitted with
hollows for anchors and pressed off bolts. The individual bed parts are connected together with bolts and nuts and locked
with hardened pins against moving.
Warning:
the connection of individual bed parts of lathe must be carried out in such a way so that the flatness of guiding ways could
not be damaged during transport and lathe erection.
CAUTION: (operator)
The continuons flow of chips and cutting lubricant to the defined place
(chip pan) should be inspected . The cutting lubricant must not leak from lathe to the floor.
At the frontal button of guard is chip pan which has responsible to receive some chips (occasionaly) and remove the guard
by taking that.
