英语翻译
Machining process and general information:
• General Information – Tooling
o Plan to have own engineering group as company expands
o Hwasung is subcontracted to do engineering currently
o Uses same cutting tools as in Korea facility – all diamond
o Regrind tools if can
o Hwasung has capability to surface grind,repair dies,and make molds with wire EDM
process
• General Information – Machining
o Boundary samples are used:okay,borderline,not good
o Quality room has separate windows for incoming and outgoing parts (for quality
checks)
o New equipment will be coming in from FM LaGrange plant
o Each operation has pictures and job instructions for what to check and which gage to
use to check part
o Parts are manually loaded into machine or pallet,depending on line
o Auditor checks parts for verification:after operator checks part,puts in bin,auditor
checks part and reloads back on line
o Have tool management system
o A pokeyoke check is used for orientation prior to loading
o Machines are guarded
o Mostly have CNC machines
o Manual chip collection systems
o If automated,have robots with grippers to load/unload parts from pallets
o After final inspection,operator visually inspects and loads onto plastic dunnage with
the crown up and loads into the washer
o Repairs:filing down of burrs or sharp edges after anodizing the crown
o Have 2 Excello machines for special machining of the pin bores
o 2.7% scrap for gasoline pistons
o Cycle time is 18 seconds for gasoline piston
o Process – Wash
o Spray system
o 4 stations:heated wash,wash with degreaser,2 rinse stations
o Uses RO water
o Operator blow dries piston and puts on dunnage with crown up
o Parts wheeled into coating room
o Needs major improvements here
o Chemical analysis done for bath in chemical room
o Comments/Observations:
o Relatively small piston facility,but plans for additional space.New facility,
July 2004.
o Currently no cleanliness checks (wash and filter) run to verify machining wash
process.
o No asm processes / equipment at facility.
o Current wash process / equipment / clean part handling would not meet GM
requirements
o Could not fully review coating process due to no production at the time of the
visit.
活塞厂考察报告谢谢

加工工艺和大体上的信息
1.大体上的信息---工具方面
1）伴随着企业规模的扩大,计划打算拥有自己的工程集团；
2）Hwasung是当前的重点工程
3）用的扦插工具跟韩国的设施基本相同,都是用钻石做得
4）如果可以,也可以用回收料工具
5）Hwasung 的表面已经研磨,并且修复了模具和模具丝电火花加工能力的过程
2.大体上的信息---加工方面
1）边界样本已经用了,边缘不是很好
2）质检部门已经有了有单独的窗口传入和传出的部件 (对它们进行质量检测）
3）新设备将从FM LaGrange 这里得到
4）每一个操作都有图解和工作介绍
5）零件是手动加载到机器或托盘中的,取决于线.
7）审计员检查验证零件, 置于 bin中,运算符检查部分后,核数师检查部分并重新加载到回行上
8）有工具管理系统
9）一个 pokeyoke检查,复选用于在加载之前的定位
10）机器都是被保护的
11）大多数都有CNC机器
12）手动芯片收集系统
13）如果自动化,有带夹子的机器人负责下载/不卸载的部分从托盘获的
14）在最后检查之后,运算符将直观地检查并加载到与塑料衬垫冠了与到洗衣机负荷
15）修理：提交下毛刺 或者 电镀冠以后会有锋利的边缘
16）有 2 Excello 机特别加工的销孔
17）2.7%废料的汽油活塞
18）周期时间是为汽油活塞式的 18 秒
19）工艺--可清洗的
20）喷淋系统
21）4站：温水清洗,与脱脂剂洗 2冲洗站
22）利用反渗透水技术
23）运算符吹干活塞式并放了冠衬垫
24）零件轮式到涂层室中
25）在这里需要重点改善
26）在化学浴房做分析
27）评论和观察
28）活塞设施相对较小,但计划提供更多的空间.新的设施, 在2004年7月
29）目前没有清洁度检查（洗涤和过滤器）运行,以验证加工洗进程
30）没有学会进程/设备,设施
31）目前清洗进程/设备/清洁部分处理不符合通用汽车要求
32）由于没有生产时的访问,所以无法充分审查镀膜工艺
本人花了很多精力完成好的,望采纳.
有问题大家一起交流!
