Although the import tool aids in durability, cutting speed, machining quality is better than the domestic cutter device, but the price is higher than domestic auxiliary knife 5 ~ 20 times. Therefore,in the process of design and the knife localization AIDS work, to deal with the price performance ratio and the comprehensive economic benefit analysis, does not need to be imported tool, do not blindly overall localization. We follow the following principles in the selection of cutter device:
The roughing process try to use homemade knife devices (such as rough milling, rough boring tooletc.), because the domestic blank allowance, tool consumption, and rough machining precision low,domestic tool easy to fill.
Drill, tap, drill, reamer, reamer etc. should try to use domestic tool. Although the cutting quality is better than the import tool, but this tool adjustment, the replacement is convenient, the price is also more cost-effective.
Machining center tool system such as a knife handle and a knife bar (especially special non-standard tool system) should be used in products for imported special non-standard cutter handle and a cutter rod price is very expensive, but the quality of the domestic NC tool system has beenbasically meet the requirements of.
