Dead Length Collets Concentricity and repeatability: To DIN 6343 on page 2 Application: For workpiece clamping (bar or chuck work) in conventional single spindle lathes and CNC-turning machines directly in the spindle or in a collet chuck (see pages 6 and 7) • plain bores are mainly used in counter spindle of CNC-turning machines Bore execution: See B in the chart • with plain bore or annular serration Collapse: h9, i.e. only nominal size can be clamped Special features: Minimal axial movement of the collet while clamping, therefore component positioning when clamping is axially consistent Remark:...

Concentricity and repeatability: Best concentricity with high flexibility Application: For workpiece clamping (bar or chuck work) as per series 100 dead length collets (see pages 6 and 7) • emergency collets are not intended for volume production Bore execution: Plain and pre-drilled as the chart Collapse: h9, i.e. only nominal size can be clamped Special features: Hardened and tempered to 45 HRC • completely ground and pre-drilled (0 see chart) • enable the customer to machine the collet bore to suit their requirement • minimum axial movement of collet while clamping Inner Stops for Dead Length...

Draw-in Collets Concentricity and repeatability: To DIN 6341 on page 2 Application: To clamp work pieces after turning, e.g. grinding and devices with high accuracy and clamping forces, best results are obtained when using close toleranced material and the correct size collet Bore execution: Plain, see B in the chart Collapse: h8, i.e. only nominal size can be clamped Special features: Higher clamping forces as dead length collets, but axial movement while clamping * max. insertion depth 11 mm (drilling at the top) Ordering examples: 386E FM613 • 20,0 mm = Order-No. 10319012000 386E FM613 Set...

Manually Operated Collet Chucks with Safety Key Application: Various possibilities on conventional as well as on CNC-machines, e.g. lathes, drills, mills and grinders • ideal for small production batches • can be used on pallets and machining centre tables (see examples at the bottom) Special features: Wear resistant construction • durable, simple design • contamination and dirt ingress almost eliminated • higher clamping force and improved concentricity due to holding workpieces with collets (see concentricity table on page 2) compared with 3 jaw chucks • large clamping range with free bar passage...
