Diamond tools for delamination-free processing

The machining of GRP and CFRP requires/calls for special know-how. Meanwhile diamond tools – either wirh diamond or PCD – belong to the standard repertoire for the processing of any type of composite materials.

LACH DIAMANT tools are highly innovative, work with highest precision and increase economic efficiency by a multiple.

Wide variety of uses on all current machines in wind turbine/rotorblade processing: CNC-, robot- and manual milling machines.

Highlight

For more than 20 years the LACH DIAMANT engineers have been working with the challenging material and with their experience and intuition – have supported the wind power industry in becoming „greener“:

The drill with internal exhaustion for a dustfree and precise drilling operations.

Drills with internal exhaustion

Innovation: PCD drills with internal exhaustion

  • patented by LACH DIAMANT
  • dust- and chipfree
  • long tool life
  • eco-friendly

Diamond tools for rotorblade production

Tools with diamond or PCD ensure a precise processing of this highly abrasive material and with maximum infeed, tool lives and reduced production cycle times.

The economic efficiency of diamond tools in this processing step is out of reach for carbide tools.

Process: cutting of the rotor blade`s root end

Solution: diamond and PCD cutting saws

PCD-tipped cutting saws

PCD-tipped cutting saws

  • long tool life

  • high infeed rates increase the machine utilisation

  • high efficiency

  • Tools can be resharpened and re-tipped several times

  • Diameters from Ø300 to 550 mm

  • usable on all current machines

Cutting saws with diamond coating

Cutting saws with diamond coating

  • Diamond coating by means of electroplating process

  • cost-effective solution

  • easy to use

  • recoatable multiple times

  • Diameters from Ø300 to 550 mm

  • usable on all current machines – also for manual milling machines

Process: face milling of the rotorblade`s root end

Solution: PCD face milling cutter

PCD monoblock milling cutters

PCD monoblock milling cutters in process

The LACH DIAMANT high-performance face milling cutters allow maximum face milling accuracy with a low degree of delamination. High feed rates reduce machining times by a multiple. Internal coolant channels for longer tool lives of the high-performance cutting tools. The PCD cutting edges can be resharpend and/or re-tipped with PCD several times.

  • Diameters from Ø80 to 220 mm
  • for SK or HSK adapters

Process: Axial drilling for threaded pins + radial drilling for threaded bushes

Solution: PCD and diamond drills

PCD Drills in root end production

PCD brazed solid drills

Also LACH DIAMANT solid drills with PCD cutting edges allow delamination-free bore entrances and outlets.

The extra-hard cutting material allows maximum feed rates reducing production times by a multiple. Internal coolant channels for longer tool lives. The PCD cutting edges can be resharpend and/or re-tipped with PCD several times.

  • also available with integrated internal exhaustion (A LACH DIAMANT innovation – see Highlight)

  • recommended for CNC machines

  • Diameters from Ø20 to 100 mm

  • for SK or HSK adapters

PCD hollow drills

  • low cutting forces

  • low vibration

  • reduced chip formation

  • Bore diameter Ø30 – 150 mm

  • for SK or HSK adapters

  • recommended for robotic systems

Diamond hollow drills

  • Diamond coating by means of electroplating process

  • cost-efficient alternative

  • low cutting forces

  • low vibration

  • minimal burr formation

  • Bore diameter Ø30 – 150 mm

  • recommended for robotic systems
