sprue point drilling mAchine

►LESS CONSTRUCTION LIMITS FOR HUB AREA No limitation of material thickness and sprue diameter brings advantage to casting speed and process efficiency

►LOW MATERIAL STRESS The drilling process causes a much lower material stress to the hub area compared to punching. Also at bigger

material thickness, no danger of deformation or cracks.

►COST REDUCTION THROUGH RECYCLINGThe used metal screen will be chipped completely, the metal parts can be separated with a magnetic conveyor

and the remaining material can be recycled to 100 %.

►CYCLE TIME REDUCTION AT MACHINING AREAThe drilling diameter can be close to machining value, less cycle time is needed in the OP1 machining operation

►FLEXIBLE PRODUCTION With a short changing time of the tool, the actual drilling diameter can be adjusted to the production need. By

using more drilling machines, each machine uses a different tool diameter to be more flexible.

sprue point drilling mAchine

2 MAKRA

The ABV machine is developed for the automatic sprue point drilling of alloy wheels after the casting process. It’s a strong and reliable machine, setting the standard for flexibility and efficiency.

Compared to the punching process, drilling of the

sprue gives a lot more flexibility regarding size and

thickness of the wheel hub area. An advantage

which becomes more and more important due to

the continuously increasing wheel size and material

thickness.

Distortion and deformation caused from the

punching process can be fully avoided with the

drilling system. Tool diameters up to 60 mm can be

used without any problems. Fast feed rate and

drilling speed can be programmed in speed and

length. Prior to the drilling machines, a design

recognition system can be used to divide and sent

the wheels to the drilling machine with the most

suitable drilling tool (diameter). Different options can

be added to the machine, i.e. mist cooling, exhaust

connection and chip conveyor.

The ABv machine can be loaded with a standard industrial robot or with a gantry loading system. The wheels will be hold in place with the well-proven MAKRA standard chucking system, including 3 step jaws. With the clamping stroke of 3 inch, a wheel diameter range of up to 9 inch can be chucked without any manual change.

The range of the jaws will be designed according actual customer requirements individually for each project. The cleaning of the chucking system is done with high pressure air nozzles. The drilling is done usually with mist cooling through the tool. The chips and the sprue will be fed out with a standard chip conveyor.

ABV - inline mAchine

Access door

For fully automatic alloy wheel production with short cycle time requirements, the ABv INLINE machine was developed. The wheels will be feed in directly on a standard conveyor into the machine with design side up. The drilling will be done from the top side of the wheel. Through massive flood cooling and flushing, chips will be washed away from the design at the wheel. Directly after the machine, a strong air nozzle system is integrated to clean and dry the wheel surface.

Centring and chucking of the wheels will be done with a cone from the top side. The sprue will be 100 % chipped during the drilling process. The chips will be feed out with a standard chip conveyor, the material of the sleeve (metal) can be separated with a magnetic conveyor from the aluminium material. Low overall investment costs, less space requirement and high output rates are the advantages of the Inline ABv machine.
