combiloop

THE COMPACT HIGH-PRESSURE UNIT

Space-saving, flexible, and up to five-digit cost savings in the production process: The innovative filter technology of our combiloop guarantees continuous and perfect purification of the cooling lubricant of your machining tools and therefore allows for the generation of exceptionally high pressure.

combistream

HIGH-PRESSURE SYSTEM AND CHIP CONVEYOR IN ONE

100% more performance using up to 300 bar! combistream is all in one: High pressure + chip conveyor + fine filter + clean liquid tank + machine tank. Your benefit? Interruption-free machining thanks to highest automation in your chip management and particularly high pressure.

SYSTEM PARTNERSHIP WITH LEADING MANUFACTURERS

Thanks to close system partnerships, we are able to offer predefined and tailor-made high-pressure CL solutions for around 80% of the leading manufacturers’ sliding headstock automatic lathes and for many short lathes such as

Citizen
DMG Mori
Manurhin
Star
Tornos
Tsugami

as well as many more.

Degree of machine contamination

The requirement for a high-pressure system is strongly determined by the degree of machine contamination.

Our special symbols allow you to find out the right high-pressure unit with respect to the machine contamination level – more or less at a glance.

Performance potential of combiloop & combistream

Performance potential of combiloop & combistream	Comment	Pressure range
Cooling lubricant purification Improved cooling and lubrication at the cutting edge Concentrated washing away of the chips when drilling, turning and milling	The range up to 30 bar must not be underestimated. Often, even very low pressures can produce excellent cutting results.	< 30 bar
Early breaking of the chips, removal of snarl, ribbon and spiral chips Drilling possible without clearing out Deep hole drilling > 5 mm possible in one go Trouble-free two-shift or three-shift operation	Probably 60% of all conventional cutting operations can be served to excellent effect with pressures in this range. High-pressure effects make the biggest difference. Very gummy materials like copper and bronze need pressures over 50 bar.	30-70 bar
Good machining of aluminium and stainless steel Deep hole drilling > 3 mm possible in one go	With the exception of smaller holes, this pressure range no doubt covers most of the high-pressure cutting operations today.	70-100 bar
Deep hole drilling > 0,5 mm possible in one go Machining of extremely hard alloys and titanium	Aluminium in conjunction with copper and silicon can be cut only with difficulty under 100 bar.	> 100 bar

POTENTIAL RATIONALISATION WITH HIGH PRESSURE

The following calculations are based on a customer's situation. The calculations refer to a turning and milling center, which is now used in combination with combiloop CL3 plus reversing flow automatic filter.

Basic data:

Turning and milling center
Machine running times (with combiloop): 192 days a year / 21 hours a day
Machine hour rate here: approx. €68 per hour

Ratio	Description	Advantage	EURO
High pressure	Drill wear	Sevenfold reductions	5.472
High pressure	Working without clearing	8% time savings	24.276
Full or partial flow filtration	No filter changes, no consumables	Time and cost advantage	1.380
Full or partial flow filtration	Improved cooling lubricant life for full flow filtration	10% cost savings	950
Energy efficiency	Regulating pump effect	Approx. 3–4 kW/h savings	2.633
Energy efficiency	Cooling for constant pump	Does not apply to CL + CS (cost advantage)	1.975
Process safety	Improved quality output	Here, the advantage can be estimated only with caution	6.000
Process safety	multishift operations possible	Here, the advantage can be estimated only with caution	6.000
Total		192 production days/year 21 hours/day	42.686
