The folting chuck is a mechanism for finishing a bore. Finishing is the last stage in part manufacture which is decisive or respecting its geometric dimensions. The floating chuck limits dimensional dispersion and geometric defects.
The need for quantity production of bores to close limits is constantly increasing, resulting in more general use of reamers Reamer manufacturers, anxious to satisfy this demand are constantly improving their products and can now supply reamers for each particular application and class of work Despite the continuously improving accuracy of machine tools, it is still a real problem to align the axis of the reamer holder with the axis of the bore to be reamed One of the main reasons for these difficulties comes from heat due to friction in bearings etc, causing expansion and resultant play and loss of spindle concentricity As you know, it has been determined that the best results are obtained when the reamer can penetrate the bore in perfect alignment and when it is free from any radial force. To obtain true alignment use the SMP floating chuck.
The tool-holder sleeve is moving on precision balls and coupled to the chuck body through an Oldham type clutch driven by means of precision rollers. The tool-holder sleeve is moving on precision balls and coupled to the chuck body through an Oldham type clutch driven by means of precision rollers. Therefore the tool keeps all its mobility regardless of the torque resulting from the cutting load This new design prevents the bearing surfaces from being damaged by the balls during an incident (if a tool snaps, in the event of a programming mistake, impact, very heavy cutting loads etc.). This new construction is covered by an SMP patent
When the tool-holder flanged sleeve is moving radially, its axis stays perfectly parallel with the chuck axis. This advantage provides absolute perpendicularity between the bore axis and the reference faces
All components of heavy duty design are made of nickel chrome steel and are hardened and ground High precision and great care are given to the manufacturing and assembling of the chucks. Therefore, the reliability of all their qualities is ensured for a long period of time.
Some reamers are designed to permit the coolant to flow through the center For this type of reamer, we offer a range of special chucks with three different means of connection
A special distortion-free nozzle with two Viton seals connects the floating bush to the chuck body
This nozzle provides perfect coolant sealing and very sensitive movement even under very high spray pressures.This new system is covered by an SMP patent.
Note : All above chucks are automatically supplied with a floating sleeve having a cylindrical bore. These chucks can also be used with standard type ESX or ER collets.
Although these collets do not have sealed channels, a new system incorporated into the floating chuck,ensures it is sealed to fluids
This provides the advantage of central spraying using standard collets (low cost, low stocks, the same collet can be used for all diameters within a 1 mm range) instead of 0,1 for collets with vulcanized channels
This is the most universal chuck. For use with all reamers it can also be utilized as a coupling whenever an application requires a parallel or angular off-set capability

All chucks of the ,Compact,, series (whose number is preceded with the letter ,C,, or «Super Compact- -SC-) have a body whose overall dimensions are reduced. They are mostly used on transfer machines and on multispindle heads. The adjustable angular correc¬tion is not available on these chucks.
