Machining and quotation of non-standard parts (Chapter 5)

In the previous section, we have discussed the gross quotations in the iron parts of automation parts, and we will discuss the gantry quotations in the iron parts immediately after that.

For what is gantry material, let's have some discussion around this topic. DomesticCNC Milling MachineThe simple classification of the situation is that there are used to process non-metal engraving machine milling machine, there is precision processing CNC machine Beijing Jingdiao, in addition to processing aluminium parts of the 550 CNC milling machine is also known as the small yellow machine, as well as the length of 800mm width of 500mm and the stroke of the CNC milling machine for the 850, and then more than 1m3 CNC machine tools are all collectively referred to as the gantry milling, the gantry milling and is divided into 1m3, 2 meters, 3 meters, and even the existence of 6 meters and 10 meters, and even the existence of 6 meters and 10 meters. The gantry milling machine is divided into 1m3, 2m, 3m, and even 6m and 10m. The gantry milling processing charges will be due to the gantry milling size increase and become higher, I based on past experience concluded that 1m 3 gantry milling hourly processing fee of 100 yuan, 2m 200 - 230 yuan per hour, 3m is 270 - 300 yuan per hour, and so on and so forth; Speaking of which, you must be clear, the so-called gantry material is the gantry milling machine, the so-called gantry milling machine is the gantry milling machine. The so-called gantry material is processed in the gantry milling machine on the A3 light plate material, gantry material to material its length, width and height dimensions can ensure that +0.4mm, flatness can be guaranteed +-0.15. Then how to calculate their material costs? Let's take an example together:

There is an automation part called side stand plate, its material is A3 gantry material, the specific specification is 830mm by 768mm by 17mm, A3 density of 0./mm, when the 45#, Q235, A3 these kinds of wool and cold drawn steel type material, we in accordance with the average market price of 5.5 yuan per kg to calculate, in the parts processing, our programming engineers intend to arrange for A3 gantry material Before the part is machined, our programming engineer intends to arrange for the A3 gantry material to be machined, and the dimensions of the machined part become 830.3 by 768.3 by 17.4, and the material cost X is equal to 835 by 773 by 23 by 0.5 by 5.5, which results in a cost of $640.9. The cost is incurred when the material supplier cuts off the raw material and later processes it into gantry material with dimensions of 830.3*768.3*17.4, the cost incurred in this case is ((835*773)/)*120, which results in $77.4, so the actual cost we need to purchase A3 gantry material is X, which is equal to 640.9 plus 77.4, which results in 718.4.

Next, we are going to explore the calculation of the processing cost of the side stand plate, so that to calculate, the specification of 830 * 768 * 17 side stand plate, will use 1 metre 3 gantry milling and large water milling with the processing. Among them, to process the series of holes in the side plate, including rectangular slots, guide slots, tooth holes, pin holes, countersunk holes, side tooth holes, and to make its appearance bright, the process time required is about 1.5 hours. After the gantry milling is finished and off the machine, it flows to the post-process to do deburring, tapping and chamfering of these operations, which takes another 1 hour. Plus clamping time of 30 minutes and quality inspection time of 10 minutes, the processing cost is calculated as follows, 2 times 100 plus 1 times 50 plus 8.3, the result is 258.3 yuan. The processing cost of the large water mill is calculated as follows, 830 times 768 times 150 divided by a certain number is equal to 95.6 yuan, the current processing price of the large water mill is 300 yuan per square mm, of course, can also be given in accordance with the machine's travel to the price of 1 metre of the large water mill is 80 yuan per square mm, 2 metres of the water mill is 150 yuan per square mm, 3 metres of the 300 yuan per square mm. the price of the market unit price As a reference standard, in the quotation, be sure to pay attention to the degree of difficulty of the parts processing and then make adjustments, the total cost of processing side panels is 258.3 plus 95.6 is equal to 353.9 yuan.

Next, we have the side risers of thesurface treatmentCosts to start the discussion, the gantry slabs are accounted for according to the square, specifically 400 yuan per square millimetre, so that the cost of plating the side panels is calculated as X830 × 768 × 400 ÷ after equal to 254 yuan.

Finally, a word about the costs generated by the control process, which are actually overheads, usually calculated as X equals the sum of the material in parentheses plus the processing costs plus the surface treatment multiplied by zero point zero seven.

Explore to this point, the crowd is clear how to quote the gantry material to report it, that is, X is equal to the bracket material plus processing fee plus surface treatment multiplied by 1.07. That is to say, the quotation of the side riser is X is equal to the bracket 718.4 plus 353.9 plus 254 and then multiplied by 1.07 is equal to 1,419.1 yuan.

There are old iron asked, why not be able to purchase A3 wool plate before going to processing it, this kind of doing is not the material that supplier's processing fee to save ah?

Whether the old iron grasp it, pleased to leave words in the comments area, the next chapter in the material for 45# bar material parts processing plus the offer on the occasion of this matter to be explored, in fact, we get the parts of the offer, of course, also want to make it clear that the parts are processed and manufactured by what way, welcome the old iron to pay attention to, welcome the old iron to leave words!
