Vargus TMSD Carbide Tooling Produces Top Gear Manufacturing Results
The TMSD range of indexable carbide insert tooling from Vargus Tooling UK offers manufacturers of gears, splines and racks a range of unrivalled advantages compared with conventional hobbing and other gear production routines.
TMSD can slash machining and set-up times by at least 50 per cent while also generating superior quality finished machined components. This is due to the higher cutting speeds than possible with HSS tooling and the elimination of subsequent finish grinding or shaving routines.
TMSD is suited to the machining of both straight and helical teeth gears, and gear modules from 1 mm to 6 mm. All materials can be accommodated, from very soft to hardened steels of 60 HRC.
Each insert profile in the TMSD portfolio is supplied with the appropriate module shape and with one, two or three cutting corners (special forms can be supplied) and a full profile can be achieved in accordance with Class 7 DIN 3962.
Importantly, because the tooling focuses on carbide inserts located in ‘standard' tool bodies for end, shell and disk milling on three-axis CNC milling machines (the cutting edge is subject to relatively low loads), TMSD is affordable by companies of every size across all industry sectors.
This is in stark contrast to the usual need for ultra-expensive hobbing machines and tooling (which also need recoating after regrinding) with their inherent lengthy set-up times. Likewise, traditional milling disks are often only suitable for rough machining on softer materials.
TMSD, therefore, alleviates the cost and potential quality problems for many companies where relatively small batches do not justify the expense of a dedicated machine – and for manufacturers, especially, the TMSD route eliminates the cost and time involved with sub-suppliers.
The benefits of Vargus TMSD tools are clear - in one case involving a 40.5 mm diameter 42CrMoS4V gear with 52 teeth, a TMSD milling operation took just 5 seconds to produce each slot: 75 per cent faster than the former, hobbing routine!
TMSD also produced similar savings in one spline milling application, and reduced gear rack production from 10.7 min to only 3.3 min. Similar benefits have also been achieved with plastic gears.
Vargus Tooling UK's MACH display will include a host of new product developments, for example: Groovex grooving solutions; 14D carbide inserts for the generation of threads in API round casings and tubings, as well as API buttress casings; and innovations from Widia, which Vargus handles as Master Distributor for the UK and Ireland. Shaviv hand deburring tools will also be available.
