10 Face Drivers FSB / SB NEIDLEIN-SPANNZEUGE GmbH www.neidlein.de Face Drivers FSB / SB 11 Face Drivers FSB / SB with drive pins and movable center pin The entire surface of the workpiece can be tooled and finished by clamping with a maximum of torque transmission. NEIDLEIN face drivers are mechanical clamping systems which are suited for turning as well as hard turning. Face drivers of type FSB / SB are power-operated by the thrust of the tailstock. Workpieces are clamped centrically using a movable center pin. This way different centerings can be adjusted, thus ensuring a constant datum-point at the end face of the workpieces. Clamping principle The center pin located on the side of the tailstock pushes the workpiece against the movable center pin of the face driver. The center pin will draw back until the surface of the workpiece bears against the drive pins. In this state the clamping bolt is clamped over the power flow in order to ensure a fixed datum-point during the entire tooling process. The drive pins are floatingly, thus compensating for variations in workpiece, squareness and surface finish. The entire surface of the workpiece can now be finished in one single clamping. Please check page 1-15 for metal removing rates to be obtained as well as for the tailstock forces required. Compatible standard drive pins and center pins are listed on page 22-28. Type FSB with flange retainer Type SB with MK- or cylindrical retainer We will be glad to design clamping devices suitable for your workpieces.

NEIDLEIN face drivers are mechanical clamping systems, suitable for turning and hard turning likewise. Face drivers of type FFB / FFBH are power-operated on the side of the machine spindle as well as the side of the tailstock. The workpieces are clamped centrically by the fixed center pin. This operation results in high true run-out accuracy. Drive pins of type FFBH are hydraulically activated and compensated, thus achieving excellent true run-out accuracy. Clamping principle The center pin located on the side of the tailstock pushes the workpiece against the fixed center pin of the face driver. The motion of the drive pins against the surface of the workpiece is initiated by the clamping cylinder mounted into the machine. The drive pins are floatingly suspended, thus compensating irregularities with regard to possible unevenness of the surface of workpieces. The datum-point of workpieces on the machines is determined by the size of the center hole. The entire surface of the workpiece can now be tooled in one single clamping. See page 20-21 with data for achievable removal of material and the thrust requested. The appropriate standard drive pins and center pins can be found on page 22-27 and page 29.

Face Drivers FSP / FSPB NEIDLEIN-SPANNZEUGE GmbH www.neidlein.de Face Drivers FSP / FSPB 5 Face Drivers FSP / FSPB with drive disk and movable center pin The entire surface of the workpiece can be tooled and finished by clamping with a maximum of torque transmission. NEIDLEIN face drivers of type FSP / FSPB with drive disks are mechanical clamping systems which are suited for soft / green as well as heavy tooling. In application, they feature maximum flexibility and high robustness. These face drivers are power-operated by the thrust of the tailstock. Workpieces are clamped centrically using a movable Type FSP with flange retainer for screw connection Type FSP is mounted onto the machine spindle nose using a flange adapter. center pin. This way different centerings can be adjusted, thus ensuring a constant datum-point at the face end of the workpiece. Type FSPB with flange retainer for jaw clamping Type FSBP is directly clamped with the chuck using soft jaws. Clamping principle The center pin located on the side of the tailstock pushes the workpiece against the movable center pin of the face driver. The center pin will draw back until the surface of the workpiece bears against the drive disk. In this state the clamping bolt is clamped over the the power flow, in order to ensure a fixed datum-point throughout the entire tooling process. The drive disk is floatingly suspended, thus balancing out possible planarity defects of the contact surface of the workpiece. The entire surface of the workpiece can now be tooled in one single clamping. See page 7 for data of achievable removal of material and the tailstock thrust requested. You will find various sizes of face drivers with appropriate standard drive disks and center pins on the following pages. In case you need special dimensions, we will be glad to design clamping devices suitable for your workpieces. Type FSP with flange retainer tailstock force F R NEIDLEIN face drivers FSP / FSPB ensure: face driver FSP workpiece live center a maximum of torque transmission, thus achieving high metal removing rates datum-point at the face end of the workpiece, stable datum-point in case of different centerings compensating drive disk for uneven face sides high flexibility in the application, wide range of clamping diameters run-out deviation max.: 0.015-0.02 mm adjustable spring force (depending on the weight of the workpiece) low setup costs due to fast change of drive disks and center pins cost efficient exchange of parts that are in contact with the workpiece (changeable carbide inserts) fixed center pin in clamped condition» fixed clamping point

2 Face Drivers FFP NEIDLEIN-SPANNZEUGE GmbH www.neidlein.de Face Drivers FFP Face Drivers FFP with drive disk and fixed center pin for high true run accuracy The entire surface of the workpiece can be tooled and finished by clamping with a maximum of torque transmission. NEIDLEIN face drivers of type FFP with drive disks are mechanical clamping systems which are suited for turning as well as for hard turning operations and can also be used for grinding operations. Type FFP with flange retainer for screw connection The face driver FFP is designed for a direct mounting onto a spindle nose. DIN 702-1 (55028) Face drivers of the type FFP are power operated on the side of the machine spindle as well as the side of the tailstock. The workpieces are clamped centrically by the fixed center pin. This operation results in high true run accuracy. Clamping principle The center pin located on the side of the tailstock pushes the workpiece against the fixed center pin of the face driver. The motion of the drive disk against the workpiece face side is initiated by the clamping cylinder mounted into the machine. The drive disk is "floatingly" suspended, thus balancing out possible planarity defects of the contact surface of the workpiece. The datum-point of workpieces on the machine is determined by the size of the center hole. The entire surface of the workpiece can now be tooled in one single clamping. See page 5 for data of cutting performance and the clamping forces requested. You will find various sizes of face drivers with appropriate standard drive disks and center pins on the following pages. In case you need special dimensions, we will be glad to design clamping devices suitable for your workpiece. Type FFP with flange retainer power operation by clamping cylinder F S tailstock force F R face driver FFP workpiece live center NEIDLEIN face drivers FFP ensure: a maximum of torque transmission, thus achieving a high cutting performance datum-point location in the center of the workpiece ensures constant measures of length compensating drive disk for uneven face sides run-out deviation max.: 0.005-0.015 mm low setup costs due to fast change of drive disks and center pins cost efficient exchange of parts that are in contact with the workpiece (changeable carbide inserts) high flexibility in the application, wide range of clamping diameters

Thus face drivers of range FFB can be assembled universally on various machines. Driving components and center pin are easily exchanged from the front part of the machine. As required, the face driver can be equipped with either drive pins comprising a chisel for machining soft workpieces, or with diamond coated drive pins for machining hardened workpieces. Apart from the clamping diameters listed above D1, D2, D, we can also provide alternative sizes upon request. We are also able to manufacture larger center pins or mushroom centers for oversize centering.
