FCWHORIZONTAL BORING MACHINE ŠKODA

The FCW machine capabilities can be considerably enhanced by application of various technological accessories. These

include chain-type tool replacement systems with tool magazines of capacity 40 to 120 tools, milling and boring heads,

measuring probes for checking the condition of the tools and the work pieces, chip conveyors, base plates and clamping

angles. Among the services offered by the machine manufacturer to the customers are process specifications for the

machining of reference work pieces, process specifications for other work pieces including supply of the required

technology, supply of the data needed for the post-processor creation, supply of the necessary clamping devices and of

the tool preparation and adjustment devices. The scope of the ŠMT supplies includes the machine assembly, installation

and commissioning, as well as the programmer and machine operator training.

:The new solution offers the following advantages

• high machine reliability;

• simple maintenance;

• original aesthetic design;

• high price vs. performance efficiency.

The company ŠKODA MACHINE TOOL a.s. continues its more than 100 years long tradition of precision machine tool

manufacturing. Based on a situation analysis and taking into account the positions of their traditional and potential

customers, the ŠMT management have decided to further develop the concept of the successful FCW product line and

prepare an innovated machine version using the latest knowledge and feedback from the application of the company's

heavy horizontal boring machines.

The new FCW horizontal boring machines will find application in dusty working environments and jobs including cast iron,

plastic material or GFK machining. They are also considered the best solution for machining box-type component parts of

complex shapes for various industries including power generation, ship-building, mining, chemical, arms and transport

equipment manufacturing.

FCW MACHINES - BASIC INFORMATION

PØEDSTAVENÍ STROJE FCW POPIS STROJE FCW

FCW spindle headstock• of a slide-type design, a box-shaped grey iron casting;

• combined rolling-contact slide guide ways of a compact

design;

• equipment for correction adjustments of the horizontal

slide movement facilitating:

• automated slide drop compensation during the slide

extension;

• automated compensation of the slide drop due

to the weight of the technological accessories fitted

onto it;

• ball screw drive for the slide extension;

• the Heidehain measuring rule for direct slide extension

measurement with compensation of the longitudinal

thermal expansion of the slide (a proprietary Škoda

patent).

Ram• a grey iron casting;

• fixed milling spindle, expandable boring spindle;

• the milling spindle seated in annular ball bearings

with oblique-angled contact;

• the spindle bearings and bearings of the final gear drive

lubricated by oil mist;

• automated monitoring of the bearing, final gear drive

and ram temperatures;

• the boring spindle accommodated with a sliding

contact in the milling spindle. The boring spindle is

a forged and nitrogen-hardened machine part;

• the cooling liquid is fed through an axial hole

in the spindle;

• the temperature of the oil bath of the main drive

transmission and of the final gear drive is stabilised

using the air cooler fitted onto the machine column;

• angle-controlled stop and spindle position indication

using a rotation sensor;

• automated milling head lubrication.

Bed• a grey iron casting;

• linear rolling-contact bearings for the column movement

on the machine bed;

• telescopic steel covers sloping in the direction to the chip

conveyor. The telescopic cover boxes slide into one another

starting at the bottom of the machine column;

• the toothed rack fitted into the bed with the displacement

box at the column traverse unit (a master-slave system);

• a linear Heidenhain measuring system for direct

measurement of the ccolumn traverse unit displacement

with respect to the machine bed.

FCW MACHINE DESCRIPTION

Column traverse unit• a grey iron casting;

• the column traverse unit moves along the machine bed

on hardened guide ways with rolling-contact elements

on the column. The guide ways are grease lubricated.

The compact rolling-contact guide system absorbs/transfers

all forces acting on the column traverse unit;

• a play-free column displacement system including two

backlesh free drives run in the master-slave mode

of operation;

• hydraulically-controlled clamping units at the carriage

corners (installed upon the customer's request);

• a sensor of the linear Heidenhain measuring system

for direct measurement of the column traverse unit

displacement with respect to the machine bed;

• the operator cabin attached to the column traverse unit

(no independent movement possible).

Column• a box-shaped grey iron casting bolted onto the column

traverse unit section;

• the compact rolling-contact guide system for the spindle

headstock movement along the column absorbs/transfers

all forces acting on the headstock;

• the spindle headstock balancing by means

of counterweights located inside the column. The cable

pulleys are fitted onto the column top plate. The cable ends

are provided with suspension elements for the headstock and

counterweights.

The FCW machine capabilities can be considerably enhanced by use of various technological accessories. Among the standard accessories available from the machine manufacturer are chain-type tool replacement systems with tool magazines of capacity 40 to 120 tools, milling and boring heads, measuring probes for checking the condition of the tools and the work pieces, chip conveyors, base plates and clamping angles. The range of types and sizes of the machining heads will meet the requirements of the most demanding customers. The complete list of the machine accessories can be found in a special brochure; the following equipment and specifications should be taken for an illustration of the available assortment.
