NEW InoFlex® Compensating 4-Jaw power chuck PATENT

With the InoFlex power chuck you can clamp all shapes of work pieces i.e round, rectangular and all irregular shapes with just one hydraulic chuck. InoFlex will increase the work piece precision and roundness accuracy and is ideal for clamping deformation sensitive parts. The unique compensating clamping of 2 + 2 jaws make this chuck a complete all-rounder for clamping all your different parts that you produce on your turning and machining centres while reducing your set-up time and cost.

The trend in CNC machining is quickly shifting towards combined turning and milling machines for both round, rectangular and geometrically irregular parts. In the past, companies have used rigid concentric 3-jaw chucks for clamping round parts and worked with vices (two jaws) for rectangular and geometrically irregular parts.

HWR has reacted to this development and produced the first universal clamping tool for clamping round, rectangular and also geometrically irregular parts. With the patent approved in 2013 for the concentric and compensating 4-jaw manual chuck InoFlex, HWR is launching a clamping tool to perform this task in a range of Ř 210-630 mm for the brand new power operated InoFlex chucks. No other clamping tool on the market can do this!

  • For concentric and compensating clamping
  • For clamping round, cubic and geometrically irregular parts
  • Suitable for deformation sensitive workpieces
  • Can be used on turning and milling machines
  • Available as power clamping and also by manual clamping
  • Ř 210-630 mm

In the range of 210-630 mm Ř, InoFlex® combines the advantages and functions of the 2-, 3- and 4-jaw chuck and vice, and avoids disadvantages such as overdetermination through its patented compensation feature.

Advantages

InoFlex® offers you the following advantages:

Four jaws for compensatory clamping

  • For eccentric and compensating clamping
  • For clamping round, cubic and geometrically irregular parts
  • Suitable for deformation-sensitive workpieces

Low-cost all-rounder

  • Can be used on turning and milling machines
  • Available as manual clamping Ř 210-630 mm
  • No expensive special clamping solutions needed

High precision and roundness accuracy

  • Precise production results confirmed in practice

How it Works

In a conventional chuck, all drive parts move in the same direction around the centre (e.g. wedge bar, wedge hook, scroll chuck) either towards or away from the centre.

The drive of the InoFlex® 4-jaw chuck (concentric compensation) moves towards or apart on two parallel axes. Compensation is provided by connecting the diametrically arranged slides with levers or a sliding gate-type gear.
