Mechanical Deburring Systems for Chamfering Toothed Parts •Mechanical chamfering Our deburring and chamfering solutions are suitable for almost any application: •From small to big diameters •From small to large series production We will define the most suitable machine type with you in order to satisfy your production requirements. Advantages of Mechanical Chamfering •Repeatability: constant quality of the machining result •Operators’ safety thanks to the closed structure of our machines machines which require little maintenance costs for chamfering tools equipment of the machine: from highly...

Tools and Machining Process Pre-Machining via Disk-Cutter Especially the hobbing process of the geared parts generates burrs with significant dimensions. As an alternative to manual filing, Tecnomacchine offers a pre-machining process, during which the burr is cut off with a disk-cutter. Standard Chamfering It is possible to use both abrasive wheels (suitable for hardened and non-hardened material) as well as end mills (only suitable for non-hardened material). Depending on the chosen machine type, the tools can be adjusted manually or can be CNCcontrolled. The pressure of the tool is adjustable...

Tool Set-Up Tecnomacchine provides three options for the adjustment of the tools during set-up: •Low-priced, highly flexible adjustment by means of handwheels •Manual, repeatable adjustment with rotary counter and nonius •CNC-controlled tools Manual Set-Up of the Tools The vertical and radial machining position is adjusted by means of handwheels. Set-Up of the CNC-Controlled Tools The CNC axes of the tools are adjusted in the JOG mode. Once the machining position for the part has been determined, the parameters are saved in the part program. Tecnomacchine thus lowers the set-up time for recurring...

Chamfering Machines for small series production •Standard: self-centering manual three-jaw chuck Alternatively: pneumatic chuck or inclinable chuck (by +/-90° for spiral bevel or internal gears), optionally also inclinable CNC-controlled chuck •PLC with touchscreen display opening on top if the production includes big / heavy parts dust collector Gear Chamfering Machine TM150 / TM150 big •Universally applicable, low-priced solution Parts with Ø30-400mm (optionally 700mm) •Standard equipment: two chamfering tools for top and bottom brushing tool bore in the chuck in order to clamp long shafts...

Chamfering Machines for Medium-Sized Serial Production The challenge with the production of medium-sized series / batches is: •The cycle time plays a stronger role as compared to small series. → solution: loading/unloading in masked time on a station positioned outside of the machining area • Having a greater variety of parts requires very short set-up times → solution: few tools, which can be easily and quickly adjusted Gear Chamfering Machine TM250 •Rotary table equipped with: Loading/unloading station outside the machining area Machining station with two chamfering tools and one optional brushing...

Chamfering Machines for Large Series Production The challenge with the production of large series / batch production is: Compliance with a maximum admitted cycle time, which is often dictated by the hobbing machine → solution: Rotary table with several workstations, each of which is takes care of one specific machining operation In case of automated machines, the down time is a significant criterion → solution: Robust mechanical and electronic components, remote technical assistance •Suitable for •Rotary table with 5 workstations 1) loading / unloading 2) and 3) chamfering top and bottom 4) and...

Solutions for Automation Our automation solutions allow our Customers to significantly reduce the need for the operator’s presence on the machine. Depending on the dimensions of the parts, our automation models are able to work autonomously for several hours. They are therefore suitable to be applied to machine medium-sized and large series/batches. Automated Basket Loader TM100 •The system can be entirely adapted to the customer’s workpart flow in the production processes •The solution includes: 1) a two- or three-bay basket loading system 2) a CNC-controlled manipulator which takes care of...

Gear Drilling Machines Tecnomacchine also supplies CNC-controlled drilling machines to make holes on gears, which require lubrication. Gear Drilling Machine TM T3 •Ø drilling units at an angle of 120° Alternatively, the TM T2 is equipped with 2 drilling units at an angle of 180° •All movements are CNC-controlled: - the radial movement of the bits - The vertical movement of the chuck - The rotation of the workpart is possible to make central, higher or lower drillings on 1, 2 or 3 differently staggered •The integrity of the bit after every drilling cycle. •Depending on the number of drilling cycles...

Example of Achieved Results Chamfering of straight-toothed or helical spur gears. The picture on the left shows the result achieved with a manually adjusted tool, while the picture on the right shows the result achieved with a CNC-controlled tool. Machining of a bronze worm gear. This result has been achieved by machining the part with a pre-machining disk-cutter, then chamfering and finally brushing the part. Machining of a spiral bevel gear. This result has been achieved by chamfering both the tip and toe by means of CBN abrasive wheels and a final brushing cycle.
