ONDRIVES LAUNCHES NEW 2011 GEAR PRODUCTS CATALOGUE

ONDRIVES CAST IRON PRECISION SPUR GEAR RANGE

Ondrives Ltd have recently extended their precision spur gear range by adding cast iron (GG25) to the already wide variety of materials available as standard.

Cast iron spur gears are available in 1.5 to 3 Mod with between 18 to 50 teeth being the norm. Generally, only the bigger sizes call for something like cast iron and Ondrives have designed these gears with this in mind.

All are made to exacting standards being made in-house at Ondrives' extensive CNC facility, and as part of the precision gear range, are the perfect addition to the series.

Cast iron has been chosen by Ondrives as it offers good strength and wear resistance, making it an excellent choice for those applications that deem these properties necessary. Cast iron is widely used in a large variety of engineering applications and this makes it a popular choice given it's resistance to destruction and weakening usually caused by rust.

Other materials available as standard are 817M40T (28 HRC) steel, 805M20 case hardened (58 HRC) steel, 303 and 316 stainless steel, PEEK GF 30®, Delrin POM, titanium and skive hobbed versions.

Customers are invited to send in any special requests whether it be for unusual materials and/or sizes to their drawings. All quotes are done on a quick turnaround and a no-obligation basis.

Cast iron GG25 is a material chosen by Ondrives for specific engineering properties such as low melting point, good fluidity, castability, excellent machinability, resistance to deformation and wear resistance making it an excellent choice for engineers where these properties are deemed necessary. Price is also a reason for choosing cast iron as it is not expensive compared to other, more unusual materials.

ONDRIVES DELRIN AND PEEK® PRECISION SPUR GEAR RANGE

Ondrives Ltd have introduced a range of Delrin POM (white) and Peek Gf30® (light brown) precision spur gears into their precision gear range of products.

These unusual materials are proving popular with customers already.

They start at 0.5 Module going up to 3.0 as standard and numbers of teeth start at 18 going up to 250 depending on which module size is selected, he continues. Different bore sizes, tapped holes, keyways and pin holes can all be added for a small extra cost to customer's specifications and complete specials are also easily and quickly quoted for and manufactured at Ondrives' newly built CNC manufacturing facility.

Peek Gf30® is a material known for it's resistance against chemicals, high tensile and impact strength and for keeping its shape. Delrin plastic material is characterised by good fatigue life, low moisture sensitivity, and high resistance to solvents and chemicals. It also contains good electrical properties. Delrin is a semi crystalline engineering plastic that is beneficial to engineering applications, and is suited to CNC machining which is why Ondrives selected both materials to further enhance their extensive precision gear range.

ONDRIVES DELRIN AND PEEK® PRECISION WORMWHEEL RANGE

Ondrives Ltd have added to their Peek GF30® and Delrin POM range of gears by making worms and wheels in the same material for their latest power transmission catalogue.

These worms and wheels start at 0.5 Mod going up to 3.0 as standard and all are available in either 1, 2, 3 or 4 starts. Worms, worm shafts and wheels are designed to be run together in either Peek GF30® (light brown) or Delrin POM (white) or with a plastic wheel running with a steel worm/worm shaft. They are made to Quality Grade 8e25 DIN 3974 and different bore sizes, keyways, tapped and pin holes are all available to order for a nominal extra charge. Complete specials are also available to customer's drawings and specifications where required.

Both of these materials have been chosen for their unique properties which make them ideal for engineering applications. Peek GF30® is a material known for it's resistance against chemicals, high tensile and impact strength and for keeping its shape. Delrin plastic material is characterised by good fatigue life, low moisture sensitivity, and high resistance to solvents and chemicals. It also contains good electrical properties. Delrin is a semi crystalline engineering plastic that is particularly suited to CNC machining making it easily modified where customer's applications call out for it.

PRECISION SPUR GEAR GEARBOX - SLIMLINE AND BORE INPUT OPTION

Ondrives Ltd have introduced a slimline version of their spur offset gearboxes for Spring 2011 These units have been designed for those applications where a smaller space envelope means a slimmer unit must be used.

Ondrives developed this product in response to customer demand for ever smaller gear reducer units within the spur gearbox range. They are, on average, 15% slimmer than their standard counterparts offering exactly the same torques, efficiencies and speeds as their bulkier cousins making them the ideal choice for those applications that need optimum output in a smaller unit. This has been achieved by the smaller units having a flush bore output and the larger sizes being bore input instead of shaft input.

All are made in-house by Ondrives using the latest CNC technology in a purpose built environment that has received recent heavy investment ensuring top quality products to exacting standards. We have made these investments in the latest CNC machinery as we believe it gives Ondrives the edge over our competitors, ensuring we meet those just-in-time requirements that all customers seem to need these days as well as offering the highest quality product for a reasonable price.

Specials are quickly quoted for where required and modifications easily incorporated into standard designs. Contact Ondrives' experienced technical team for more information and assistance.

ONDRIVES INVEST IN S21

Ondrives Ltd have recently taken receipt of a new grinding machine called the S21 designed for the grinding of workpieces in individual as well as small and large series production operations.

The company hopes this will take Ondrives to the next level in terms of grinding our precision gears on-site, maintaining our high standards in both product terms and customer service levels.

The S21 is especially suitable for grinding high precision workpieces, as required by the aerospace, precision mechanics and hydraulic/pneumatic sectors. The centre height of the unit purchased by Ondrives is 125mm (4.9") and the centre distance is 400mm (15.7").

There is a turret wheelhead that swivels automatically, a frequency controlled motor grinding spindle for external and internal grinding from 42,000 to 60,000 rpm and it is able to sense when about to touch on for grinding. As well as an automatic dressing of the grinding wheel using studiers latest software that brings a high level of functions to grinding operations which are not available on older machines. This makes it a multi-functional machine for Ondrives' grinding operations on so many different levels that it was absolutely necessary to add this to their extensive, up-to-date range of CNC machines.

The workhead for universal use in live grinding operations and grinding between centres is of particular use and Ondrives decided to have the option of having a workhead specially designed for grinding chuck components also fitted, so that every eventuality is covered where necessary. There is a full enclosure with 2 sliding doors and the machine base is made of Granitan making this a truly exceptional piece of kit that feels right at home at Ondrives' impressive manufacturing plant.

Ondrives can undertake all types of grinding work as well as other types of CNC milling and manufacturing. Their range of in-house manufactured precision and commercial gears are amongst their most popular ranges of products along with the famous red anodised gearboxes, all manufactured in the UK and Ondrives especially welcome the opportunity to quote for complete specials as well as modified standards.
