functions. It can be used as a standard 3-axis or even a 5-axis machining centre in combination with the rotary ultrasound.
faster than conventional machining. The PZT Piezoelectric Principle is applied during vertical vibrations. The compact size of this machine needs very little floor space while machining speed produces more parts per hour than similar machines from competing manufacturers. The machine is made up of a very rigid column and a moveable desk. The ballast, the frame, as well as the column, together with the other constructed parts, are all made using casting from MEEHANITE high-strength alloy. Linear sliding roller guides, which produce 2.5 times higher rigidity as compared to ball-type guides are used for moving axes X, Y and Z. This ensures high rigidity with quick
In conclusion, I would like to say that the companies listed here are CNC invest's key partners and their machines have been serving many satisfied customers for several years now. We will be happy to welcome anyone interested in more information on delivery, service etc. at our exhibition at the MSV 2019 Expo in Brno – Hall P – booth 024.
TONGTAI VU-5 Ultrasonic MicroHole Drilling A typical application is "MicroHole" drilling of miniature bores and machining glass, sapphire, silicon carbide, quartz, ceramics, quenched steel alloy with a high nickel and non-ferrous material content. Any material, which is softer than the cutting tool can be machined using this ULTRASONIC technology. Rotary ultrasound machining combines high speed spindle rotation with a high frequency, with vertical vibration of the cutting tool. The diamond tool "hits" the material at high contact speed, which significantly reduces the cutting strength and produces ultralight soft surfaces while increasing cutting efficiency; which is 3 to 5 times
and precise movements. 25 mm diameter ballscrews are in accuracy category no. 3, with a double pre-stressed nut, which allows for standard work with a shift of up to 20 000 mm/min and an axis acceleration of 1.2 G. Tools of various shapes can be attached into the special ER11 (ER16/20 option also available) tong holder for machining, using ULTRASONIC technology. TONGTAI uses fantastic ultrasound control technologies to reach axis vibrations of the tools at a frequency of 15 to 45 kHZ, with a maximum spindle rotation speed of up to 24 000 tpm with unparalleled accuracy. This technology significantly decreases bore edge chipping. The 3-axis tool is equipped with the Siemens 828D control system, a 10.4" TFT display, with ShopMill and Advanced Surface. This machine belongs to the elite category of TONGTAI products.
