用途及加工精度:用于粗、精铣曲轴箱两气缸贴合面和两侧手门盖面。两气缸贴合面与主轴孔中心线平行度为0.02/100毫米,光洁度（?）4。生产率:当负荷率为75％时,班产7件,较通用设备提高工效4.1倍。自动化程度:气吊及人工辅助装卸,手动定位夹紧,按钮操纵,实现快进-工进-快退自动工作循环。结构特点:本机床由专用铸铁底座、焊接45°斜座、机械动力滑台、铣头、夹具等组成。工作采用一面两销手动定位。夹具以气动楔铁
Use and Processing Accuracy: For rough, fine-milled crankcase two-cylinder fitting surface and both sides of the door cover. Two cylinder fit with the spindle centerline parallelism of 0.02 / 100 mm, finish (?) 4. Productivity: When the load rate of 75%, the production of 7 classes, compared with general-purpose equipment to improve efficiency 4.1 times. Degree of automation: pneumatic lifting and manual loading and unloading, manual positioning and clamping, button control, fast forward - work - rewind automatic work cycle. Structural features: The machine consists of a special cast iron base, welding 45 ° inclined seat, mechanical power slide, milling head, fixtures and other components. Work using one side two pin manual positioning. Fixture to pneumatic wedge iron
