Info Product Finder More information regarding Speedsynchro ® Modular at www.speedsynchro.com 7.8 Collet holders Speedsynchro ® Modular Application range Speedsynchro ® Modular are designed for use on CNC-controlled machine tools. Functionality The Speedsynchro ® Modular uses an integrated transmission gearing with a transmission ratio of 1 :4.412 and combines it with the patented Softsynchro ® minimal length compensation function. The transmission gearing allows • To work in the unproblematic and relatively low synchronous spindle speed range (< 1500 rpm) of the machine tool • To achieve high cutting speeds of the threading tool due to a multiplication of the spindle speed General specifications • Higher cutting speeds In a synchronous thread production machine spindles do not achieve the programmed rotational speeds above a certain spindle speed. The transmission gearing of the Speedsynchro ® Modular keeps up with the programmed speeds. • Longer tool life The patented minimal length compensation function reduces the axial force on the tap. • Reduction of energy consumption Thanks to the transmission gearing the rotational speed of the machine spindle is reduced which results in energy savings of more than 90% compared to synchronous thread machining. • Reduced installation costs Lower energy consumption due to the use of minimum quantity lubrication (MQL). - Modular MQL tubes Conversion from 1-channel to 2-channel MQL-systems. - Modular length adjustment screws Adaption of length adjustment screws to threading tools with male or female center. Technical characteristics • Cutting range: M1 - M8 • Collet: ER16 • Transmission ratio: 1 :4.412 • Max. spindle speed: 2000 rpm • Max. tool speed: 8824 rpm • Internal coolant supply • MQL for 1-channel or 2-channel systems Advantages of the Speedsynchro ® Modular • Simple programming as synchronous cycle with feed program adapted to the transmission ratio • Evaluation of time benefit of the Speedsynchro ® Modular / synchronous cycle by a “simulation” without Speedsynchro ® Modular and tool • Accurate thread depths – no variations in thread depths associated with conventional tapping attachments since the Speedsynchro ® Modular in contrast to tapping attachments does not reverse the sense of rotation • The reversal of the threading tool is done by the machine drive spindle: - No switching components in the Speedsynchro ® Modular - Low wear and longer maintenance intervals - Maintenance independent of number of threads produced • Patented constructive independent transfer of the machining torque in the production of threads • Mechanically independent compensation of the axial forces at the threading tool flanks caused by synchronization faults • Minimum length compensation ± 0.5 mm • Spring-loaded bearing of the length adjustment screw for compensation of the occurring axial force between length adjustment screw and threading tool when tightening the clamping nut • Self-locking of the length adjustment screw against unwanted length displacement caused by rotation acceleration during reversal of rotation direction of the machine spindle Thread production cycle with the Speedsynchro ® Modular The Speedsynchro ® Modular is changed into the machine by means of the tool exchanging device, the stop fixture bolt engages in the stop block, the locking device is released and the Speedsynchro ® Modular is ready for operation. Some programming references The transmission ratio of the Speedsynchro ® Modular is 1:4.412 which results in the following programming guidelines: • Feed f f = P x 4.412 [mm/rev. resp. inch/rev.] • Rotational speed n of machine spindle for the desired tool speed n MSP = n TOOL / 4.412 [rpm] P = Pitch of threading tool [mm resp. inch] n MSP = Rotational speed of machine spindle [rpm] n TOOL = Rotational speed of threading tool [rpm] Example thread M6 / pitch P = 1 mm: • Desired rotational speed of threading tool: n TOOL = 3000 rpm • Required rotational speed of machine spindle: n MSP = 3000 rpm / 4.412 = 680 rpm • Required feed: f = 1 x 4.412 mm/rev. = 4.412 mm/rev.
