Cutting forces frequency and amplitude using the Toodle™

The Toodle™ driving element is either hydraulic (in the case of Toodle Blue™) or pneumatic (in the case of Toodle Green™). In either device, jets are located in front of the turbine in order to convert the potential energy (pressure) to kinetic energy. The jets increase the speed of the hydraulic fluid (Toodle Blue™) or the air (Toodle Green™) and [...]

Toodle™ filtration grade requirements

The Toodle™ includes several narrow corridors for air, emulsion or oil. The areas most susceptible to damage due to improper filtration are: Bearings – between the shield and the inner race Jets – at the turbine blades Turbine – at the gap between the turbine and the housing ID Exhaust – at the exhaust jets [...]

High speed machining

One of the key parameters in metal cutting applications is the “Chip-Load Per Tooth” (CPT). CPT is the average chip thickness that is removed with each cutting-tool tooth per one 360° cutting-tool turn. Producing the right CTP will result in increased tool life, better surface quality and cutting geometries. In order to achieve optimum CPT, [...]

Through-coolant Pressure in Milling Machines

Milling machines with “through-the-main-spindle” coolant pressure have been gaining popularity. This through-coolant feature is used mostly for drilling applications using drills that include through-holes. SFI’s Toodle Blue™ models use through-coolant pressure to drive the Toodle Blue™ turbine. Toodle Blue models include special jets which convert pressure into linear speed. Higher pressure values deliver higher linear [...]

Operating the Toodle Green – air driven

Toodle Green models are powered by compressed air. Fluctuations in the air pressure may result in fluctuating Toodle Green rotation speeds. In order to avoid rotation speed fluctuations, one must pay attention to the following rules; An “FRL” unit (Filter, Regulator, Lubrication) is required to operate the Toodle Green, with the air supply flowing through [...]

Poggipolini Italy

The Emilia Romagna region, located in northern Italy, is famous for its history of passion and excellence in various sectors, but it is also known as Motor Valley. It is the birthplace of important companies engaged both in motorsports and in high-performance automobiles such as Ferrari, Maserati, Lamborghini, Pagani, and Ducati.   Since the 1950's [...]

NEW – SFI Pressure Gauge

Metal cutting machines include the option of coolant through the main spindle. The use is mainly for deep drilling applications. The high-pressure emulsion helps to remove the metal chips from the drilled hole.   The SFI Toodle Spindles use the coolant through the main spindle in order to drive the turbine spindle. The machine pump [...]

Why the Toodle performs better than other speed increasers?

The Toodle is the most advanced, innovative speed increaser ever. Except for the Toodle, all other speed increasers include the following modules: housing, bearings, shaft and tool clamping system. The design concept of a conventional speed increaser is in principle the same as any conventional spindle. The speed increasers rotate at relative high speeds, which [...]

Toodle – finally a spindle which saves you money

The vast majority of metal machine shop expenses are: machine costs; maintenance; staff salaries; AC; and materials. Cutting tools account for only a small portion of the total expenses going into a specific job. And yet, machine shops spend significant efforts in reducing tool expenses and maximizing the usage of each and every tool. When [...]
