New range of TOHP tool holders with very high-pressure coolant through.

High pressure in tool cooling it’s the current trend, so we propose a release (patented) solution for driving tool holders with high pressure cooling (up to 150 bar) with TOHP technology. This system offers a smoother, faster cut and longer tool life. Conventional cooling does not reach the cutting point and as consequence the edge of the tool heats up quickly and, when cooled, results in a disastrous thermal shock, with cracks and evaporation of lubricant.

The use of high pressure brings us to a new age, where the lubricant fully complies its mission and easily reaches the cutting edge, between the material to be cut and the tool. Correct evacuation of chips to the outside part is obtained and there is no turbulence in the cutting area.

Complete high-pressure machining (static and rotary) with our tool holders results in significant savings in cycle times and tool life. There is fluid control, so the fluid acts where it is needed. It allows operations that could not be carried out until now in conventional machines (deep drilling).

The main and principals’ advantages are:

  • Coolant pressure up to 150 bar, for cutting oil and emulsion.
  • Available for all types of tool-holder spindles.
  • Independent channels for each tool. Controlled flow and pressure in each output.
  • No leaks inside the tool. TOHP system is external.
  • Savings in cycle times around 25-30% (proved).
  • No more chip problems – improved chip control. Smaller chip production.
  • Great economic and tool life savings: higher returns are obtained.
  • Improved surface quality – no high temperature during machining.
  • Eco-friendly: respectful with the environment.
  • System in the backside of the nut. Protected from impacts, chips and liquid. The possibility of collisions with parts of machine its reduced.
  • Specially designed to maintain the original tool length
  • System also in the backside of the spindle. Super protected from impacts, chips and liquid. The possibility of collisions with parts of machine its reduced.
