1.3 Proper use

WARNING!
In the event of improper use of the bench drill

• there may be a risk to personnel,

• there may be a risk to the machine and other items,
correct functioning of the bench drill may be affected.

The bench drill is designed and manufactured to be used in environments where there is no
potential danger of explosion. The bench drill is designed and manufactured to produce holes in
cold metal or other not health hazardous or not burnable material by using a rotating cutting tool
with several chucking grooves.

If the bench drill is used in any way other than prescribed above, modified without authorization
of Optimum Maschinen Germany GmbH, then the bench drill is being used improperly.

We do not take liability for damage caused through improper use.
We would like to accent that any modifications to the construction, or technical or technological

modifications that have not been authorized by Optimum Maschinen Germany GmbH will also
expire the guarantee.

It is also part of proper use that

 the maximum values of the bench drill are complied with,
 the operating manual is constantly observed,
 inspection and maintenance instructions are observed.

 „Technical Data“ on page 14

WARNING!
Very serious injury.

It is forbidden to make any modifications or alternations to the operating values of the
bench drill! They could endanger employees and cause damage to thebench drill.

1.4 Possible dangers caused by the bench drill.

The bench drill is state of the art.
Nevertheless, there is a residual risk as the bench drill operates with

 high revolutions,
 rotating parts,
 electrical voltage and currents.

We have used construction resources and safety techniques to minimi ze the health risk to per­sons resulting from these hazards.

If the bench drill is used and maintained by employees who are poorly qualified, then there
might be a risk resulting from incorrect operation and unsuitable maintenance of the bench drill.

INFORMATION

4.9 Cooling

The friction generated during rotation can cause the edge of the tool to become very hot.
The tool should be cooled during the drilling process. Cooling the tool with a suitable cooling

lubricant ensures better working results and a longer edge life of the tools.
This is best realised by a separate cooling equipment. If there is no cooling equipment included

in the delivery volume, you can cool by means of a spray gun or a washing bottle.

CAUTION!
Danger of injury due to brushes getting caught or pulled in.

Use a spray gun or a washing bottle for cooling.

INFORMATION

Use a water-soluble and non-polluant drilling emulsion which can be obtained from authorised
distributors.

Make sure that the cooling agent is being collected.
Respect the environment when disposing any lubricants and cooling agents.
Follow the manufacturer’s disposal instructions.

4.10 Before starting the working process

Before you start working, select the required speed. It is depending on the drilling diameter and
on the material used.

 „Determining the cutting speed and the spee d“ on page 28
 „Speed table“ on page 24

WARNING!
For drilling jobs, it is necessary to

clamp the workpiece firmly to pre­vent the bit catching on the pieces.
Example of suitable clamping
devices include a machine vice or
clamping jaws.

Img.4-9: Seats for clamping blocks

Put a wooden or plastic board beneath the workpiece to avoid drilling through to the work table,
vice, etc.

Use the drill depth stop when you want to have several bore holes with the same depth.
When working with wood, make sure to use an adequate dust extraction unit, as sawdust can

constitute a health hazard. Also use a suitable protective mask for any work that generates dust.

4.11 During the working process

The spindle sleeve feed is being p erformed by th e star grip. Make sur e that the feed is being at
a regular pace and not to fast.

The reset of the spindle sleeve is being performed by a track recoil spring.

WARNING!
Danger of clothing / or long hair getting caught.

• Make sure to wear a well-fitting work suit during drilling work.

• Do not use gloves.

• If necessary, wear a hairnet.

CAUTION!
Danger of bumps by the levers on the star grip.

Do not release the star grip when repositioning the drilling spindle sleeve.

CAUTION!
Danger of crushing! Do not place your hand between the drill head and the spindle

sleeve.

INFORMATION

The smaller the bit, the more likely it is to break.
In the case of deep drilling, remove the bit from time to time to remove drilling chips from the

bore hole. A few drops of oil will reduce friction and prolong the service life of the bit.

5.3 Examples to calculatory determine the required speed for your drilling
machine

The necessary speed is depending on the diameter of the drill bit, on the material which is being
machined as well as on the cutting material of the drill bit.

Material which needs to be drilled: St37
Cutting material (drill bit): HSS spiral bit
Set point of the cutting speed [

v

c

] according to the table: 40 meters per minute
Diameter [d] of your drill bit: 30 mm = 0,03 m [meters]
Selected infeed [f] according to the table: about 0.35 mm/rev

Speed

Set a speed on your drilling machine which is less than the determined speed.

INFORMATION

In order to facilitate the production of larger drill holes they need to be pre-drilled. This way, you
reduce the cutting forces and improve the guiding of the drill bit.

The pre-drilling diameter is depending on the length of the
chisel edge. The chisel edge does not cut, but it squeezes
the material. The chisel edge is positioned at an angle of 55°
to the major cutting edge.

As a general rule of thumb it applies: The pre-drilling
diameter is depending on the length of the chisel edge.

Recommended working steps for a drilling diameter of 30 mm

Example:
1st working step: Pre-drilling with Ø 5 mm.
2nd working step: Pre-drilling with Ø 15 mm.
3rd working step: Drilling with Ø 30 mm.

6 Maintenance

In this chapter you will find important information about

 inspection,
 maintenance,
 repair.

The diagram below shows which of these headings each task falls under.

Img.6-1: Maintenance – Definition according to DIN 31051

ATTENTION!
Properly performed regular maintenance is an essential prerequisite for

• safe operation,

• faulty-free operation,

• long service life of the machine and

• the quality of the products you manufacture.

Installation and equipment from other manufacturers must be in optimum conditio n.

ENVIRONMENTAL PROTECTION
During work on the bit-holder head, make sure that

• collector vessels are used, with sufficient capacity for the amount of liquid to be col­lected.

• liquid and oils are not split on the ground.

Clean up any split liquids or oils immediately using proper oil-absorption methods and dispose
of them in accordance with current legal requirements on the environment.

Cleaning up spillages

Do not re-introduce liquids split outside the system during repair or as result of leakage from the
reserve tank: collect them in a collecting vessel to be disposed of.

Disposal

Never dump oil or other pollutant substances in water inlets, rivers or channels.
