MBA4216/5型珩磨机床是大河珩磨机床研究所1982年研制的新产品。该机床是在基型产品MBA4215基础上派生出来的。MBA4215主要用于多缸内燃机汽缸孔的珩磨加工,其生产率和加工精度等主要指标比较先进,但它控制主油缸的液压操纵箱采用时间控制制动换向,换向精度较低,一般换向超程量(从最高往复速度到最低往复速度换向点的位置误差,下简称换向精度。)在20毫米以上。近来发动机行业的改型换代对珩磨机提出了新的要求,新型
MBA4216 / 5 type honing machine is a river honing machine tool research institute developed in 1982 new products. The machine is based on the base product MBA4215 derived. MBA4215 is mainly used for multi-cylinder engine cylinder bore honing, its productivity and precision machining and other major indicators of more advanced, but it controls the main hydraulic control box using time-controlled braking commutation, commutation accuracy is low, the general commutation Over the amount of (from the maximum reciprocating speed to the minimum reciprocating speed reversal point position error, referred to as commutation accuracy.) In 20 mm or more. Recently, the engine industry, the replacement of honing machines put forward new requirements, new
