    摘要: A method of casting-in-place iron cylinder liners in light alloy, preferably aluminium, engine blocks is made possible by a cylinder liner insert comprising at least two generally cylindrical cylinder liners (102) which are joined together along aligned portions of the liners in a "semi-siamese" fashion. The cylinder liners are joined at the lower ends (106) of the liners (102) with the upper combustion ends (104) remaining independent and unattached. Alternately, narrow ribs can be formed at or arched above the upper ends (104) of the liners to join and stabilise the upper ends (104) of the liners (102) during cylinder block casting operations, with such ribs ultimately being machined off during block finishing operations.

    摘要: Valve seats (13,14) are machined at the end of an axially deep, narrow cavity (11) of a workpiece (10) having an axially clampable surface within the cavity adjacent one or more valve seats. The method comprehends: (a) supporting a rotary driven spindle (34) of sufficient length to extend through the axial extent of the cavity (11) and reach the valve seat (13,14) the spindle (34) carrying a cutting tool (35) at its extremity, the support being a nonrotatable housing (32) effective to fit closely to the interior of the cavity (11) within a tolerance of 0.025 cm (.01 inches) and effective to move along the axis (12) of the cavity (11) to bring the cutting tool (35) into machining contact with the valve seats (13, 14); (b) securing a radially rigid but axially resilient diaphram (51) to the end of the housing (33), the diaphram (51) extending transversely across the interior of the cavity (11); (c) after inserting the housing and spindle into the cavity so that the cutting tool is proximate the valve seat but out of contact therewith, axially clamping a portion of the diaphram (51) remote from the spindle, against the axially clampable surface, and (d) moving the rotary driven spindle assembly (30) axially toward the valve seat (13,14) to conduct machining contact of the cutting tool (35) therewith, the axially resilient diaphram (51) providing accurate supporting alignment for the tool (35) under even high speed machining conditions.

    摘要: Stitch-machining the walls of a cylindrical blind cavity (10) of a workpiece (14), the cavity (13) being deep and narrow with respect to the axis of the cavity, is carried out by: (a) supporting a tubular housing (10) for axial movement throughout substantially the axial extent of the cavity interior and in close-fitting tolerance to the walls of the cavity, the tubular housing (10) having a free end; (b) rotationally driving a spindle (23) in the tubular housing (10) for conjoint axial movement with the tubular housing, the spindle (23) extending beyond the housing (10) end for carrying a radially adjustable cutting tool (24); (c) inserting the tubular housing (10) together with the rotationally driven spindle (23) in the cavity (13) with the cutting tool (24) radially positioned for rough boring of the cavity walls, while guiding and steering the tubular housing (10) and spindle (23) to accurately concentrically position the cutting tool (24) with respect to the cavity axis ; and (d) substantially immediately upon the execution of rough boring, withdrawing the tubular housing (10) together with the rotationally driven spindle (23) from the cavity with the cutting tool (24) repositioned for finish boring of the cavity wall during withdrawal.
