Heavy-duty SS locking pins introduced
Heavy-duty stainless steel additions to a range of button handle locking pins are now available in two-ball and four-ball (high tension) versions in various diameter and grip length sizes.
Grooving special magnetic alloys
Special Mircona toolholders and inserts have been supplied to Parmeko in just four weeks by Advanced Carbide Tooling for small-diameter deep face-grooving on proportional solenoid housings.
Arc-Fit is a low-cost answer to producing specified angular joints in two hits on pipe and thick wall tubing.
The Mitre-Snug is for fitting mitre joints and the Arc-Snug designed for the rapid notching of round, square, oval or rectangular tubing to form 25 to 90 deg angular joints.
* Workholding systems - workholding equipment ranges from T-slot bolts, self-adjusting washers and nuts to hydraulic-powered clamps, quick change chuck jaws and machine vices (vises).

Parting-off analysed and best solution found
Choosing the most effective parting-off tooling has resulted in a subcontractor achieving the best speeds, feeds and programming method to be used.
3000 radio-metal components parted off per insert
Specialist turned parts manufacturer is successfully parting-off batches of 3000 radio-metal components with a single TiN-coated cobalt high speed steel insert.
The Foxy Vice quick change vice system is one example from this extensive range, providing low-cost accurate and positive workholding - like the cartridge-loaded die set for presses based on the Japanese-inspired SMED (Single Minute Exchange of Die) principles - whether as a stand-alone system or as part of a dedicated fixturing solution.
* Jigs and fixturing - typical products a include Quick Locate and Lock fixture plate change-over systems, such as the Jergens Quick Change Ball Lock mounting system that reduces downtime without sacrificing accuracy.
Fixture plate change-over can be completed in less than 1 min on all types of machine tool, with the fixture plate secured to 'receiver bushings' located in the machine table or to a sub-plate by up to 20,000 lbf/9000kgf pull-down force.
* Tooling components - Amtec nuts and systems enable a high clamping force to be achieved with the minimum of effort by the simple expedient of replacing conventional torque-loaded thread fastening with strategically-applied hydraulic force.
In operation a pressurised thrust ring is pushed against the counterface to produce an axial clamping force.
Amtec nuts can, therefore, be used either to rapidly, precisely and securely clamp tools and components or to pre-tension bolts and tie-rods.
Amtec nuts are just one of the many high-quality tooling components available from Coburg Engineering.
Another example is the Kwik Lok range of pins and quick-release ball lock pins.
These are offered in a wide range of diameters and grip lengths, metric and imperial sizes, and a choice of steel and stainless steel versions.
Heavy-duty stainless steel additions to the Kwik- Lok range of button handle locking pins are offered in two-ball and four-ball (high tension) versions for applications across the board, from jigs and fixturing to lifting equipment, aircraft landing gear, racing car steering wheels and boat rigging.
* Hoist and lifting system components - a recent addition to the choice of hoist rings has a load capacity up to 50 000 lb/22 500kg.
The environmentally-friendly Envirolox nickel-based protective finish available as standard on these particular centre-pull style hoist rings provides surface hardness, lubricity and effective corrosion protection under extreme conditions, with each hoist ring inch/metric colour-coded - gold for inch sizes and silver for metric sizes - and supplied with an individual certificate of proof-test.
The material is certified alloy steel, with all components heat treated and all forged or cast components 100 per cent magnetic particle inspected.
The maximum load capacity is stamped on individual hoist rings, as is the torque required when installing or re-tightening a hoist ring.
* Repair and maintenance - keylocking threaded inserts in metric and imperial sizes solve several common metalworking problems, said Coburg to manufacturingtalk.
Stripped, damaged or worn internal threads are easily replaced by new, stronger threads, without the need for special tools.
These inserts can also be used to strengthen parent materials such as aluminium, and to repair holes that have been drilled and tapped oversize or to compensate for holes that have been drilled and tapped in the wrong location - by, in effect, re-positioning the centre axis.
To prevent the insert rotating when it is installed, opposed locking keys - four for inserts with an internal thread size of M7 or larger and two for smaller inserts - are simply driven down into the surrounding base material, securing the insert in place.
Steel and stainless steel versions of Keylocking threaded inserts are supplied as standard in a range of styles that include thin wall, heavy duty, extra heavy duty and solid.
And for applications such as marine use or in maintenance situations where corrosion is an ever-present threat, inserts can be supplied in Inconel, Nimonic 60 stainless or Inconel 718, with a choice of finishes such as cadmium plated or dry film lube and silvering.
Inserts are also available in MS and NAS styles, and can, if required, be manufactured to specific requirements.
* Standard parts Coburg's 'Standard parts' include hand wheels; balls, knobs and nuts; and handles, levers and cranks.
Depending on the product and its application, there is a comprehensive selection of materials and styles with Coburg Engineering confident that it can meet any engineering requirement requiring the use of these types of component.
