The Royal QG Combo Chuck represents the next generation of Royal Products' QG-65 Accu-Length CNC Collet Chuck. The all-in-one solution is a Quick-Grip Collet Chuck as well as an ID workholding system.
At its core, this is a Quick-Grip Accu-Length Collet Chuck, and because there is no Z-axis movement of the collet or workpiece, the chuck is suited for main and sub-spindle applications.
The chuck can also be quickly converted to an ID workholding system simply by attaching the nose cap and mandrel. Changeover time takes just minutes, and no adjusting of the prox switches is required. For very small diameter work, a 5C collet nose is also available (pullback actuation).
Changing collets on a Royal Quick-Grip collet chuck takes just a few seconds. A hook and groove design for securing the collet is used instead of traditional threads. With a gripping range of 0.062" per collet, there is no need to worry if stock is off-size, the company reported. With all Royal QG Collet Chucks, the collet segments always remain parallel to the workpiece for full length part engagement, enabling more aggressive chip removal.
All chuck components, except for the drawtube connector, are hardened to Rc 61-63 for high rigidity and durability. An included anodized aluminum ring protects the precision locating taper from chip exposure when using as a conventional collet chuck.
Like all Royal QG Collet Chucks, accuracy is guaranteed to be within 0.0002" TIR when being used as a collet chuck, and the ID mandrel can be dialed in to almost absolute zero when being used as an ID system.
The nose cap that houses the ID mandrel is based upon a precision face/taper interface to offer near-perfect repeatability during changeovers. The mounting taper is located on the back side of the nose and is protected from chips by an aluminum ring when the ID system is not being used.
All Royal QG Collet Chucks include a custom-machined drawtube connector and all mounting hardware for hassle-free installation.
The chuck body incorporates an oversized flange to protect the machine tool spindle bearings from coolant penetration.
How It Works
To maintain precise Z-axis positioning of the workpiece, the collet in a Royal Accu-Length Collet Chuck is fixed to the body and the chuck's closing sleeve pushes forward over the collet to compress it. The collet, and therefore the workpiece, remains fixed in the Z-position. With the Royal ID Workholding System, the mandrel is fixed to the chuck body and a tapered pin is pulled back into the sleeve to expand it.
The Royal QG Combo Chuck uses a motion reversal adapter that converts the push-forward action of the closing sleeve to pullback motion that actuates the ID system via a series of hardened wedges. The method, the company reported, is simple, effective and extremely durable. (Note: actuator pressure may need to be adjusted to achieve optimal clamping force.)
