<\/p><h4>APPLICATION<\/h4><p>The <b>HUNGER VD4HD<\/b> is a versatile<br\/>machine featuring modular components for<\/p><ul><li>machining valve seats,<\/li><li>facing sealing surfaces on cylinder heads, cylinder liners, and engine blocks, and<\/li><li>boring out valve seat ring bores on large diesel and gas engines.<\/li><\/ul><h3>Features:<\/h3><p>Two electric motors ensure a uniform drive of the boring head.<\/p><p>The boring head is interchangeable, allowing the specified seat angle to be maintained with precision through proper selection of the boring head.<br\/>Roundness, concentricity, seat angle, and surface finish of the machined valve seat meet the specifications of engine manufacturers.<br\/>With a facing head available as an accessory, the machine can be operated as the VD4HD-RC facing lathe.<br\/>With a taper turning head available as an accessory, the machine can be used as the VD4HD\/-30\u00b0 taper lathe for reconditioning the tapered surface on the valve cage.<br\/>With a boring gear head available as an accessory, the machine can be utilized as the VD4HD-ADM boring machine for boring out valve seat pockets to install oversize seat rings.<\/p><h3>Operation:<\/h3><p>First, clamp the pilot with the mounted cross-arm support into the valve guide.<br\/>Mount the machine onto the pilot and position the cutting tool in front of the inner edge of the valve seat.<br\/>Set the cutting depth using the finely graduated infeed scale.<br\/>Boring proceeds automatically.<br\/>At the push of a button, the valve seat is turned from the inside out at the specified seat angle.<\/p><p>If a predecessor model VD4E is already on hand, feed gearboxes, boring heads, pilots, and cross-arm supports can also be used in conjunction with the more powerful VD4HD drive unit.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\n<\/div>\n<div class=\"elementor-element elementor-element-472f094f e-con e-atomic-element e-flexbox-base e-default-div
