Proper use

The TRUMPF TKF 104-1 bevelling machine a

pneumatic hand machine

•for preparation of all K-, V-, X-, and Y-shaped

welding joints with three different bevel angles

and correspondingly adjustable bevel lengths

needed for gas and electrical fusion-welding,

•for shaping even, non-oxidizing, bare metal bevel

edges in steel and aluminium,

•for machining chrome steel and other high-tensile

materials,

(Recommendation: model with speed control),

•for bevelling straight and curved edges provided

that the minimum radius of concave curves is

55mm,

•for bevelling edges on flat and bent workpieces,

particularly tubes, with an inner diameter of at

least 80mm,

•for bevelling edges in both directions, in which

bevelling can be started and terminated anywhere

on the sheet edge,

•for bevelling edges in normal position (carrier

under the machine) and in "upside-down position"

(carrier over the machine). This is particularly

advantageous when bevelling X- and K-shaped

welding joints.

Safety instructions

Hazardless working with this unit is only

feasible if you read the operating manual and

safety instructions (red print with the

TRUMPF identity number 125699) completely

and follow the instructions included therein.

Danger of injury

Check the unit, compressed-air tube and

reception coupling before each use.

Have all damaged parts repaired by an

expert.

Danger of injury

Hot chips are ejected from the chip ejector at

extremely high speeds. You should therefore

use a swarf box to collect the ejected chips.

Fig. 10977

Danger of injury

The machine is supported by the workpiece

as long as they are in contact when the

cutting arrangement is "normal" (workpiece

is horizontal). Remember that the entire

weight of the machine must be supported as

soon as it is removed from the machined

edge. (aid: suspension bracket with balancer

or retaining rope).

Always wear safety glasses, ear

protection, protective gloves and

proper footwear when working with

the machine.

•Do not connect the compressed air unless the

machine is turned off.

•Always disconnect the compressed-air tube from

the machine before beginning any work on the

machine!

•Always guide the compressed-air tube back away

from the unit.

•Use only original TRUMPF accessories.

Damage to property

Check the edge of the cutting tool every hour.

Check the oil lubrication of the compressed-

air motor every hour.

Never work with blunt tools!

(the compressed-air motor may stop).

Turning the unit on and off

Fig. 11424

Turning on the unit: Push lever 1 forward (releases

compressed-air). Shift lever 2 (= motor ON). The

motor runs as long as the lever is pressed. Release

lever 1.

Cooling and lubrication

The cutting results are improved and the service life of

the cutting tool is increased if

•before machining the workpiece

the cutting track is coated with oil.

Recommended for steel:

Punching and nibbling oil, order no. 103387

Recommended for aluminium:

Wisura oil, order no. 125874

Working with the machine

Damage to property

Turn on the machine before beginning to cut

the sheets.!

•Put the machine on the sheet and leave a few

centimetres clearance between the cutting tool

and the edge of the sheet.

•Turn on the machine and push it against the edge

of the sheet as far as possible (piercing).

•Push the machine along the sheet so that the

machine axle is approximately parallel to the

sheet edge. Press the machine against the sheet

edge.

Sheet thickness

Fig. 11408

•Place the machine on the sheet (working

position).

•Unscrew the clamping screw (54).

•Adapt the rest plate (45) to the sheet thickness

using the spindle (47). In doing so, leave 0.5 to

1 mm play.

•Tighten spindle (47) with clamping screw (54).

Adjusting the height of the cutting

tool

The height of the cutting tool (9) must be set so that it

penetrates the support (50) by approx. 1 mm.

•Turn the eccentric shaft (21) until the cutting tool

(9) reaches its lowest point (LT = lower dead

centre).

•Unscrew the clamping screw (36).

•Turn the supporting body (52) 360° as many times

as necessary to reach the correct punch

Selecting a cutting tool

The following cutting tools may be used to machine

sheets made of various materials and with various

tensile strengths:

Fig. 9666

Cutting tool Order no.

•for mild steel (= standard cutting tool) 088503

•for high-tensile sheets 089335

•for aluminium 005014

•heavy-duty cutting tool 110399

Warning: Optimal application of the heavy-duty

cutting tool is guaranteed only in conjunction with

speed control (Option for electrical model of the

bevelling machine). Order no. of speed control:

Sharpening the cutting tool

Fig. 9666

•The cutting tool for mild steel (order no. 088503)

and high-tensile sheets (order no. 089335) has

two cutting edges. It must be resharpened when

both edges are blunt.

•Resharpen the cutting tool at the ends (90°) on

the front side if both cutting edges are blunt.

The minimum length must be maintained.

Shorter cutting tools are useless.

•The cutting tools for aluminium and the heavy-

duty cutting tools are sharpened slantways at the

front side. Please observe the corresponding

sharpening diagram.

Compressed-air motor l u b r i c a t i o n

Damage to property

Lubrication of the compressed-air motor

is very important. The motor will fail if it

is operated without lubrication even for a

short time.

There are two ways to check that the compressed-air

motor is properly lubricated:

1. For short operating times or varying operating

sites via the internal oil chamber.

See Fig. 11425

•You must ensure that the oil level in the oil

chamber is sufficient before each use.

Lubricating interval: approx. 1 operating hour

•Oil is refilled through the opening in the

sealing screw, screw-plug (313).

•Ensure that the oil level is not too high.

2. It is receommended that an oil mist

lubricating device (e.g. Atlas Copco DIM

25) be installed in the compressed-air line for

continuous operation.

Checking the oil supply of the motor

Hold a piece of paper in front of the exhaust opening

in the motor housing while the machine is running.

The oil supply is sufficient if oil stains form.

Recommended oils (compressed-air motor

lubrication):

•BP Energol RD 80 (-15 to +10° C),

•BP Energol RD-E80 (+10 to +30° C),

•Shell Tellus Oil 15 (-15 to +10° C),

•Torculla 33 (+10 to +30° C).

Motor bearing l u b r i c a t i o n

The ball bearing in the motor flange is to be lubricated

via the lubricating head using a grease gun.

See Fig. 11425

Lubricating interval: every 10 operating hours
