Tool holders with DirectCooling system (DC)

DirectCooling system

 

Accurate rather than spurted on: a new dimension of cooling tool cutting edges

When it comes to cooling lubrication, a little more may be required - but certainly not aimlessly and uncontrollably, because the efficient use of resources and sustainability make simple flood lubrication a thing of the past. The DirectCooling (DC) range from CERATIZIT offers accurate and targeted cooling rather than flood lubrication of the general area - and in doing so delivers the ultimate in precision.

How does DirectCooling (DC) work?

Tool holders with DirectCooling (DC) are equipped with two inner holes that guide the coolant to where it has the greatest impact: directly on the cutting edge. One hole targets the rake face from above and the other the flank from below. Why is this so important?
The precision flank cooling of the DirectCooling tool holder makes the difference: it extends tool lives by up to 63% compared to cooling that is targeted exclusively at the rake face.

   

  • Fewer trapped chips
  • Reduced wear
  • Universal application

Advantages/benefits


The lengths of all CERATIZIT DirectCooling holders are ideally matched to one another.

As a result...

  • Interference contours are eliminated
  • A compact complete package is created
  • Optimum stability is reached
  • Unlimited flexibility is achieved
So, in terms of transfer, instead of emptying a bucketful into the machining zone, we target the cutting edges precisely.

Advantages of the MaxiLock-S-DC turning tool holder

     

  • Sustainable alternative to flood lubrication
  • Accurate not liberal, precisely applied not spurted on: the DirectCooling (DC) system applies coolant exactly where it is needed.
  • Can be used for any application from a coolant pressure of 10 bar
  • Compatible with turning centres or turning-milling centres on which coolant is transferred via the turret
  • Interference contours are eliminated: holders from the DirectCooling series have all been ideally matched to one another and also offer optimal stability and unlimited flexibility.
  • The nozzles of the MaxiLock-S DC turning tool holder can be replaced – for long, accurate cooling.
  1. Dual cooling (rake face and flank)
  2. G1/8" lateral coolant connection
  3. Coolant transfer from below via adapter possible
  4. G1/8" rear coolant connection

Test report: Longitudinal turning of 1.4301

Indexable insert: CCMT 120408EN-M55 CTPM125
Material: 1.4301 – X5CrNi18-10
Cutting data: vc 200 m/min | f 0.25 mm/U | ap 2 mm

Result: With the DirectCooling cooling system, the tool life can be increased by 63% compared with a conventional cooling situation.

What's interesting here is that the lower coolant hole on the flank of the indexable insert has a considerable influence on the tool life. While cooling exclusively through the upper two nozzles gives rise to an improvement of just 22%, flank cooling achieves an increase of 63% compared with standard cooling!

   

Advantages of the MaxiLock – N-DC turning tool holder

        

  • Accurate not liberal, precisely applied not spurted on: the DirectCooling (DC) system applies coolant exactly where it is needed.
  • Can be used for any application from a coolant pressure of 10 bar
  • Compatible with turning centres or turning-milling centres on which coolant is transferred via the turret
  • Interference contours are eliminated: the lengths of the holders from the DirectCooling series have all been ideally matched to one another and also offer optimal stability and unlimited flexibility.

  3. Coolant transfer from below via adapter possible
  4. G1/8" lateral coolant connection

Advantages of the MonoClamp – GX-DC grooving holder

       

  • DirectCooling can be used for any application; the only prerequisite is that the coolant must be transferred via the turret of the turning centre or turning-milling centre
  • The MonoClamp GX-DC tool holders are ideal for deep grooves, as a high flow volume reliably flushes out any chips
  • The danger of trapped chips is reduced
  • DirectCooling ensures reduced overall wear
  • The revamped insert seat clamps the grooving insert in the insert holder with even greater stability
  • Better handling – changing inserts could not be easier, as the insert clamping screw can be turned from both above and below

  2. Coolant transfer from below via adapter possible
  3. G1/8" lateral coolant connection
  4. Dual cooling (rake face and flank)

Advantages of the universal VDI adapter – DC

        

  • The VDI holder with DirectCooling is incredibly versatile owing to its 4-in-1 functionality 
  • Thanks to its double tooth profile, only one holder is needed (two variants would typically be necessary for normal and overhead applications)
  • Optional extra: the clamping rails can be attached at the top or bottom to eliminate the need for an extra holder on the left and right
  • The danger of trapped chips is reduced
  • It ensures reduced overall wear
  • DirectCooling can be used for any application; the only prerequisite is that the coolant must be transferred via the turret of the turning centre or turning-milling centre
  1. Top clamping rail
  2. Bottom clamping rail
  3. Top tooth profile (normal application)
  4. Bottom tooth profile (overhead application)
