Dimac Tooling, Australia and New Zealand’s leading supplier of accessories and workholding solutions for CNC milling and CNC turning machine tools, is the agent for the range of WTO high precision static and driven toolholders for turning centres.
For many years WTO has continued to set the benchmark for driven tool technology with its inventions. Their technological and superior products are known for achieving higher productivity and long tool life.
WTO have now introduced a revolutionary new mini spindle, with rotation speeds up to a staggering 75,000rpm allowing the workpiece top surface to be machined and the unit to perform milling, drilling, chamfering and engraving with absolute precision.
The CoolSpeed mini provides many significant benefits including time savings and ultimately cost reductions. Because the spindle runs true you can be guaranteed longer tool life and shorter machining times. The main spindle also offers longer life and frees the machine to perform other tasks.
“One of the other key benefits of the CoolSpeed mini is that WTO have priced it extremely competitively which will enable many more companies to take advantage of this unique product,” said Dimac Managing Director, Paul Fowler.
The CoolSpeed mini requires no machine adaptations, it fits into standard sealed tool holders, and several CoolSpeed mini units may be applied into the machine magazine during the machine set-up.
CoolSpeed mini spindles are driven by through-coolant meaning no external power source is required, and depending on pressure operates at up to 75,000rpm.
The CoolSpeed mini can also perform drilling applications on various materials. The friction clamping between the turbine and tool shank is strong enough to overcome axial forces during drilling.
For soft materials it is recommend that drills up to 5mm are utilised. For hard materials drills up to 3mm are recommended. The feed rate in drilling applications is extremely important, and should be optimised according to machine and tool parameters.
An assembly device is available and used to assemble the bearings and turbine onto the tool shank. There are separate assembly devices for tool shanks in 3mm, 4mm and 6mm sizes.
WTO have also recognised the need to provide an affordable replacement kit that
includes two bearings and one turbine. These unique replacement kits are once again designed for tool shanks of 3mm, 4mm and 6mm size.
Another CoolSpeed model is the mini Air which is driven by mist lubricated air. Offering the same features as the CoolSpeed mini, the mini Air operates under 5 – 7 [bar] of air pressure (mist), providing 55,000 rpm. Oil mist is the preferred option as oil is the basic lubricant for the unit’s ball bearings. The best choice of oil for the CoolSpeed mini Air is a low viscosity (VG10 to VG22) synthetic oil.
For maximum convenience, the CoolSpeed mini can simply be removed from the tool holder at the end of the day, washed through with running water, sprayed with a protective lubricant such as WD-40, and placed in a safe place for re-use the next day.
“Like all the products we sell, the WTO CoolSpeed mini and mini Air have the full back up and support of Dimac technical personnel to ensure the product operates at optimum performance,” Mr Fowler concluded.
