鑄件（HT250）

　　巨岡磨床主機(jī)座,、工作臺(tái)等全部鑄件體均采用HT250高等級(jí)灰口鑄鐵,，并經(jīng)由有限元分析與計(jì)算，達(dá)到提高剛性與質(zhì)量的工程需求,，每件鑄件均經(jīng)過高溫回火和6個(gè)月以上的自然時(shí)效方式消除內(nèi)應(yīng)力(鑄件在爐內(nèi)升溫至550一570,，保溫5~6H,再以每小時(shí)50度降至100度以下),，機(jī)床床體穩(wěn)定不變形，并具有良好的抗彎及抗扭應(yīng)力,，確保了巨岡磨床持久工作精度,。
　　Al our castings such as main engine seat , workbench , etcof grinders are HT250 high - grade gray cast iron , whichcan meet the engirieering demands of imp foving rigidityand quality through finite analysis and calculations . Everycasting has undergone high temperature tempering andnatural failure of over 6 months in order to eliminate internalstress ( al castings are heated to 550-570 in the fumacemaintain temperature lor 5-6H, and then drop below 100Cata rate of 50'C per hour ) so that the machine body can bestable and free of defomation, and beoome superior in temsof resistance to bending and torsion stress toensurethe longte mWorking acuracy of the grinder.

人工鏟刮

　　巨岡磨床采用硬軌全人工刮研工藝，崗位員工工作經(jīng)驗(yàn)均達(dá)10年以上,，鏟刮部件精度基準(zhǔn)點(diǎn)控制在每平方厘米10一12點(diǎn)范圍內(nèi),，導(dǎo)軌面貼合進(jìn)口高品質(zhì)鐵氟龍?jiān)黾幽湍バ裕瑴p低阻尼系數(shù),，能給機(jī)床運(yùn)行提供足夠的研磨精度保證
　　Our arindina machines are al fited with fuly manual scraping process of hard track . Al workers have the workincexperence of over 10 years . The precision reference point of the scraping parts is controlled within 10-12points percm The guide ralil surface is ited with imported hioh -auality Teon to enhance abrasion resistance and reducedamping coeficient , so as to ensure enough grinding accuracy far machine running .

滾珠絲杠

　　巨岡磨床所采用的絲桿均為P3級(jí)高精度滾珠絲桿滾動(dòng)摩擦系數(shù)小,，傳動(dòng)效率高，其效率可達(dá)90%以上,，摩擦系數(shù)在0.002~0.005;有效降低摩擦系數(shù)與速度的差異,，起動(dòng)扭矩接近運(yùn)轉(zhuǎn)扭矩，所以工作平穩(wěn)無沖擊,，磨損小且壽命長,，可用調(diào)整裝置調(diào)整頂緊力，傳動(dòng)精度與剛度均得到提高具有傳動(dòng)可逆性,，即可將回轉(zhuǎn)運(yùn)動(dòng)變?yōu)橹本€運(yùn)動(dòng)又可把直線運(yùn)動(dòng)變?yōu)榛剞D(zhuǎn)運(yùn)動(dòng),，有效提高機(jī)床工作精度和淑嚨址墑淆揉按定性,。
　　The screws of our grinders are as of 的 high precisiontype , which is featured by low rolling friction ooefficientand high transmission efficiency ( above 9096).Thefriction coefficient fro .002-0.005:it can reduce theciference between friction ooefficient and speed effectivelyand the starting torque is similar to running torquewhich oontributes to stable and impact - free working ，litle abrasion and long service life , Moreover, the gapcan be adjusted by adjustment device in order to imp Tove transmission accuracy and rigidity . In additiontransmission reversibility is designed to change therotary motion into linear moticn or vice versa , so asto improve the workingaccuracy and stability of themachine dramaticaly .

主軸性能表述

　　巨岡磨床全系列所使用的每一支主軸,，都完全由臺(tái)灣知名品牌 POSA,、HS 提供，主軸配裝日本NSK-CP4級(jí)精密斜角滾珠軸承,，保證主軸偏轉(zhuǎn)遠(yuǎn)低于0.002mm,，其主軸工作穩(wěn)定性和耐用性可滿足機(jī)床正常使用十年以上
　　Each spindle used in the whole series of Jugang grindingmachines is completely oomposed of Taiwan famousbrands POSA and HS provide, and the spindle is equippedwith Japan NSK-CP4 precision bevel bal bearing ensuresspindle deflection It is far less than 0.002mm, and itsworking stability and durability can be Meet the normaluse of the machine tool for more than 10 years
