In the administrative levels that machines a process in the metal, grinding is normally final or what undertake on workpiece is adjacent final treatment process. As nice spare parts passes all sorts of treatment courses, milling, turning, heat treatment is waited a moment, the value of the spare parts also increases ceaselessly. What be located in treatment process as a result of grinding is final, when because this is become,the spare parts arrives at grinding working procedure, they had been close to its maximum price to be worth. Can take a risk to assume anything but right now in front the quality of working procedure already up to mark. Have plant of a professional grinding, namely Asteroid grinding company (be located in Yilinuosi city of city Des Plaines) , reached with many 200 client in 30 old histories " accredit but want test and verify " policy. Asteriod undertakes machining for different processing factory, its business originates other the factory that relies on Asteriod grinding skill. Graph 1: Terry Magnus is the director of branch of grinding of Asteroid company CNC. CNC grinding skill and detect it is OK that process unifinication has helped this professional grinding factory in shorter delivery time and higher quality the respect satisfies client requirement. CNC is in charge of Terry Magnus to say: "Take from other plant when you ' in the process ' workpiece and when must realizing final measure and norms of exterior surface roughness, detect and measure it is as important like grinding itself to become. Their both interweaves together cheek by jowl. " Asteroid of business brief introduction is a dye-in-the-wood aircraft processing factory. Accordingly, the flexibility of the process is the sth used to one's own advantage with gain a success the most significant. The company held water 1966 as factory of an inadvertently grinding work, have perforative feed and transverse feed capacity. About 5 years ago, its branch formed CNC external diameter / internal diameter is ground. To CNC business, typical batch is 10 ～ 5000. The great majority that Asteroid place handles is cylindrical workpiece needs two working procedure, namely before path working procedure of the line after mixing. Workpiece arrives from outfit clip disassemble average total time is 1~2 hour. The grinder that match deputy decorate with unit form, in order to accelerate grinding process. The first group of working procedure are on a machine tool undertake, and the 2nd group is on the 2nd machine tool undertake. Mr Magnus says: "We choose ordinal grinding. Accordingly, to any tolerancepublic errand problems, can solve before running whole lot. Run 3 unit by two operator. " graph 2: Asteroid arranges his CNC grinding machine " comprise by two machine tools " unit form. Most workpiece needs two working procedure, because every machine tool is become by the setting,machine one of two working procedure. Asteroid has 33 stuff. Company grinding and polish the workpiece of all sorts of material, include steel, stainless steel, aluminous, acrylic, copper, pottery and porcelain and brass to wait. Can be in the diametical size scope of this factory grinding 0.

060 inches of ～ 4 inches. The most work that enters Asteroid passes pretreatment. Mr Magnus says: "We do not undertake milling and turning are operated. Because we are workpiece is in,arrive at the final personnel that the product contacts before client hand is medium, because this affirmation should face the enormous pressure of rapid turnover workpiece. This is grinding experience and measure reach detect the place that experience union rises and makes eligible part quickly. Popularly, we are 3 days to the turnaround time of an order. " the collect of the process is didymous the grinding factory at be like Asteroid, detect and measure like operating itself to obtaining a success to be like grinding crucial. Two respects must cooperate ability closely to produce the part that gives contented and relevant norms. Mr Magnus says: "Machining every phase of the process, our application detects relevantly the level will ensure good grinding. Regard a machine as the processing factory, we must are like on quality control like the respect is being machined in the metal agile. The workpiece of some clients needs of 100% detect; And other need 5 possibly however to detect hourly only and the CpK that assures a regulation. " Asteroid special finish oneself manufacturing job systematically. It regards operator, grinder and metric system is must the independence of mutual cooperation is unit. This is an interdependent process, need operator has the technical ability that installs machine tool and metric equipment specific task is proper and efficiently in the light of some. The machine tool must carry the noncombatant duty of a need, and metric equipment must affirm the spare parts is the means grinding according to process designing set, and must detect give any error of an existence. Mr Magnus says: "For example, on a workpiece, belt of blueprint regulation public errand is 0.

005 inches, and actual we are in all the time 0.

0002 inches inside process work. So this one system satisfies a requirement. " graph 3: Every grinding unit deploys metric equipment to let operator check spare parts and setting machine tool (Zun Tu) . A center detects the branch is offerred 2 times detect and affirm (right graph) . The measurement that checks Asteroid threefold and detect the process divides into 3 paces: Before the process, after the process is being reached in the process. Because great majority is on factory CNC grinder,the workpiece of treatment comes from at other plant, should be opposite so ' in the process ' workpiece undertakes checking in order to determine dimension and amount. In addition, most part passes heat treatment, accordingly this is planted initiative it is OK to detect whether to put any is out of shape in what happen because of heat treatment certainly. Once affirmed the quality of the spare parts that take a plant and amount, be about to create method and program for CNC machine tool, undertake attempering for this workpiece next. Undertake the machine tool is installed next again, include nap emery wheel, adjust tip and setting ' in the process metric equipment. After had installed the machine tool and suiting to machine some to approve a part, operator should measure 5 the first batch parts. If they are thought to satisfy a requirement, over there the member that can be sent a workshop to detect, affirm the measured value that operator obtains by him. Ability can continue to machine this to approve work later. Once affirmed the quality of the spare parts that take a plant and amount, be about to create method and program for CNC machine tool, undertake attempering for this workpiece next.

If they are thought to satisfy a requirement, over there the member that can be sent a workshop to detect, affirm the measured value that operator obtains by him. Ability can continue to machine this to approve work later. When machining this to approve work, want to undertake detecting to horary norm at the same time. Detect the SPC requirement of basis client and part are complex degree different and different. In the control of in-house statistic process in him Asteroid, detect hourly at least a spare parts. In configured equestrian Persia Unimar on the machine tool of metric equipment, ' in the process ' measuring undertake automatically. Use this automatic measure feature of metric equipment, the change of emery wheel tatty, hot growth and hardware data surplus CNC system that adopts grinder tries to compensate. Mr Magnus says: "Pass monitoring of this kind of process, operator can vacate time to run the 2nd machine tool or examination part. Because if metric equipment discovers,have appearance of out of tolerance, can shut a machine tool automatically. Grinding unit is resting or lunch time still can carry movement. " graph 4: The grinding of this gear is comprised by two working procedure. This setting is aimed at the 2nd group of device. Every metric equipment is a sheet points to unit, double what be individual and metric equipment because of the size scope that every groups of metric equipment can get used to. The metric equipment group of right measures radius of neck of the 2nd music, and left metric equipment group measures critical gear width. When moving end, the finished product with grinding unit good treatment operator give detect branch, be opposite by it whole batch the spare parts undertakes sampling finally detecting. If all eligible, criterion workpiece can prepare to deliver goods. Because devote oneself to 0 blemish production,good practice Asteroid gains a success is. Use a hand to use the combination with automatic and metric equipment, and operator and detect the redundant examination that the branch has, this factory had realized a kind in productivity and quality respect efficient balanced. Will be measured and detect compositive rise in machining a process and not be block up of Asteroid deliver the goods on time ability. Mr Magnus says: "The means that our system works very be successful: The problem is detected as the one part of overall process and solve, and the discovery after won't appearing in workpiece to machine goes out whole batch the circumstance with unqualified spare parts. " A Shops Good Reputation Is Hard To Build And Easy To Lose.

Consistent Quality Is Key To Keeping Customers.

In Its 30-plus Year History, this Chicago Specialty Grinding Job Shop Has Never Taken Quality For Granted.

Apply goodly for Sidebar below about Asteroid grinding factory how the grinding skill oneself and measure / testing system collect becomes to not have seam a process, among them a series of aviation gear pump that an example is its place treatment. This batches of spare partses have a variety of changing model, the unit of Feng Tian GL4 that forms by two machine tools in Asteroid is in charge of machining them. Critical gear wide range is 0.

10 inches of ～ 3 inches. The CNC of Asteroid grinding factory is in charge of Terry Magnus to say: "The grinding of this spare parts and metric, be (metric equipment of CNC grinder and Unimar gives machine of the flexibility that circumstance of job shops application brings) a very good demonstration. " when beginning this process, operator adjusts with mechanical means metric point to, want the part of treatment in order to suit. This stop through adjusting simply move bolt to be able to come true. Unimar metric equipment uses sheet to point to a form, every journey 12mm that point to. Graph 5: What show in the graph is Asteroid the shape of a few small size in the spare parts series that in its the weights and measures technique in the process is being used on CNC grinding unit machines. This spare parts uses a pair of only heads cylindrical grinder is machined with two working procedure. In the first working procedure, a journal on grinding axis finishs fixed position. Emery wheel " light kiss " the flank of gear, with clean surface and end panel. Of this spare parts fiducial it is to pass an installation to be on emery wheel head, stand by gear measure a head to build. In the 2nd working procedure, by left and metric point to measure the range in the grinding in the first working procedure, in order to build the transverse position between the tip. Emery wheel is transverse feed, begin the grinding of the 2nd journal. When the diameter of journal is close to place to require measure, begin the 2nd side of grinding gear. The critical dimension of workpiece is the width of gear, because gear uses a kind of metal - metallic weather strip is aimed at pump case sealed. Dimension is through have the aid of of Unimar metric equipment its P5 amplifier undertakes ' the pilot in the process. The CNC of this amplifier and machine tool joins, monitor grinding at any time in automatic grinding mode, undertake be compensatinged automatically to the machine tool. Mr Magnus says: "We come with this system grinding the spare parts with a series of appearances are similar and different measurement. Of metric equipment change gender and range easily, and of CNC grinder but process designing sex, crucial to productivity. Crucial to productivity.. CNC Milling CNC Machining
