Q:4.2 of drill bit, drill bit, old broken... Material (aluminum bar).. please help me, how to do it will do well

Lathe or drilling machine, with coolant, it should be very good, ah, more than a few back.

Q:What are the saw blades of the cutting aluminum bar? What are the cuts on the cutting surface?

It depends on the characteristics of your saw machine to optimize the sawing effect...

Q:How long is the length of the aluminum rod used in the production of the aluminum alloy line?

As long as we know the rice weight of the aluminum rod used and the theory of the extruded section, we should choose the right length of aluminum bar

Q:The difference between the o state and the h112 state of aluminum bars

Aluminum alloy basic condition code: F free machining state. Applicable to the products in the forming process, which require special requirements for working hardening and heat treatment conditions, the mechanical properties of this state product are not specified (not common) O annealing state.

Q:Can aluminum rod heating furnace be free of exhaust gas and no exhaust?

Heating by electricity can be, but that kind of calculation has not been seen, generally burning coal and burning gas, if burning coal and burning gas, there must be exhaust exhaust areas, mainly carbon dioxide and sulfur and dust

Q:How about 15?The speed of 2800/ is alloy blade. Aluminum rod diameter 10MM--40MM. Cut into slices of 7MM. Now, the cut cross section has a dull edge

Replacing the alloy saw blade and increasing the speed of the blade can solve the problem.

Q:Our company is to do aluminum extrusion, first of all, buy aluminum ingot processing into aluminum rods, and then back the company squeezed into aluminum, extrusion process has damaged, damaged from new processing into aluminum rod, how to do accounting entries?

Outsourcing:Processing materials by entrustmentLoan raw materialPayment of processing fees:Processing materials by entrustmentTax payable - VAT - inputLoan bank depositTake back：Borrow raw materialsEntrusted processing materials

Q:Which material is hard, 7075 aluminum bar or 6065 aluminum bar?

The hardness of 7075 aluminum bars is higher than 6065 aluminum bars

Q:Aluminum rod casting speed is under water leakage

Grain refinement Aluminum Alloy casting process to solve important halo pores, coarse grain, bright crystal, feather crystal, casting defects such as crack effect measures are non crystalline alloy casting balance of impurity elements (including alloy elements) the vast set of cloth grain boundary grain is grain boundary area more impurities (or Jin Yuansu) even more impurity words to reduce the damage of high uniformity and even small amounts of impurities and variations of alloy elements;

Q:Aluminum rods saw out of aluminum slag, 1 tons can dissolve how many aluminum ingots, dissolved aluminum ingot what equipment, tools?

The molten aluminum can be simple or complex, see investment, the most simple with a coke oven, a graphite crucible on the line, slow fire slow boil.
