2 10 Face Drivers FSB / SB NEIDLEIN-SPANNZEUGE GmbH 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 Type FSB with flange retainer Type SB with MK- or cylindrical retainer We will be glad to design clamping devices suitable for your workpieces.

4 1 Face Drivers FSB / SB NEIDLEIN-SPANNZEUGE GmbH Face Drivers FSB / SB 15 Face Drivers FSB / SB Calculations tailstock force / maximum chip cross section of metal removing PRINCIPLE: The tailstock force pushes the workpiece agianst 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. Chisel load of drive pins Keep the chisel load within the following range: N per mm chisel length the chisel load is calculated as follows: EXEMPLIFICATION: turning with FSB face driver, 6 drive pins, respective length of chisel mm, tailstock force 7200 N tailstock force F R BS = F R n s BS [N / mm] chisel load F R [N] tailstock force n [ - ] number of drive pins s [mm] chisel length BS = 7200 N 6 mm = 00 N mm face driver FSB workpiece live center CALCULATION EXAMPLE for type FSB / SB tailstock force F R : The force onto the face driver required for metal removing is calculated on the basis of the empirical formula: F R = [(q max 1000 D d ) ] m q max = F R [N] tailstock force q max [mm 2 ] maximum of chip cross section for metal removing D [mm] cutting diameter d [mm] clamping diameter m [-] material factor (see adjustment-chart below) maximum chip cross section q max : At a given tailstock force, maximum chip cross section is calculated as follows: F R m D 1000 d Specific data of machine and workpiece: maximum tailstock force: N material of the workpiece: C15E diameter of the workpiece, side of face driver: Ø 8 mm turning diameter: Ø 90 mm tailstock force F R : In order to ensure sufficient entrainment (see chisel load of drive pins) a tailstock force of approx N has to be supplied. Selection of face driver: face driver FSB / clamping Ø mm 6 drive pins each mm chisel length maximum chip cross section q max : The maximum chip cross section (at the ultimate turning-ø) is calculated as follows: EXPLANATORY NOTES: The calculations refer to tooling against the face driver. In case of tooling against tailstock the calculated chip cross section is reduced by approx. 0 %. The first chip, however, should always be machined toward the face driver, in order to achieve an ideal penetration of the drive pins. The ratio D / d should not exceed 2, otherwise it would work inefficiently.

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 with data for achievable removal of material and the thrust requested. The appropriate standard drive pins and center pins can be found on page and page 29. We will be glad to design clamping devices suitable for your workpieces.

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.

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.

Type FFBR with flange retainer Face drivers types FFBR/FBSR are power-operated on the side of the spindle. The workpieces are clamped centrically using a dead center pin, this way a high true running accuracy is achieved. Type FBSR with morse taper retainer 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 workpiece can now be tooled in one single clamping. There are two retainer designs for adapting the face drivers onto the machine spindle either for adaption onto a flange adapter with 10 in diameter or for direct mounting onto a spinde nose DIN size 6 (DIN 55026/28). Like face driver FFBR, but including morse taper shank and extracting nut. Adjustment true by using set screws inside shank for highest true running accuracy.

NEIDLEIN face drivers are clamping systems, which are equally suitable for grinding soft and hard workpieces. Face drivers of types FFB / FFBH are power-operated on the side of the spindle. Originally conceived for turning, face drivers of type FFB / FFBH provide a multitude of possible applications for grinding. Without retraction of drive pins and with NEIDLEIN retainer Ø 100 type FFB / FFBH provides an alternative to face drivers of type FFB / FFBH, especially when machining large-size workpieces. When FFBH is used, the compensation of drive pins is implemented hydraulically, thus achieving excellent true runout results.

We supply these flange adapters for various sizes of spindle heads in standardized size (DIN ISO / DIN 702-1) or for vendor-specific spindle heads in particular. 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.
