機(jī)床的主要特點(diǎn) Main Characteristics

? 機(jī)床床身采用優(yōu)質(zhì)鑄件澆鑄，剛性好，結(jié)構(gòu)穩(wěn)，變形小;

機(jī)床采用床頭箱固定在進(jìn)給滑板上工件進(jìn)給，車刀及砂輪作往復(fù)結(jié)構(gòu)布局，車刀置砂輪前面;

? 工件進(jìn)給滑板及砂輪工作臺滑板采用高剛度十字交叉滾珠導(dǎo)軌;

? 工件進(jìn)給由伺服電機(jī)經(jīng)聯(lián)軸器帶動高精度滾珠絲桿副來實(shí)現(xiàn)，進(jìn)給和補(bǔ)償為同一傳動鏈，結(jié)構(gòu)緊湊，精度高;

工件主軸采用箱體主軸結(jié)構(gòu)，主軸軸承采用日本光洋高精度成對軸承，回轉(zhuǎn)精度高，穩(wěn)定性好，主軸回轉(zhuǎn)采用變頻調(diào)速;

機(jī)床配有防水全封閉罩殼，觀察窗保證長期觀察清晰，耐油污并保證砂輪破碎后不飛濺傷人;

機(jī)床采用后置電器箱和前置回轉(zhuǎn)式操作臺以及獨(dú)立的循環(huán)啟動按鈕。電箱帶熱交換器，以及確保在高溫期間正常運(yùn)行:

機(jī)床可據(jù)加工零件設(shè)計(jì)制作專用夾具:

機(jī)床采用西門子808D數(shù)控系統(tǒng)，用戶如有特殊要求可選用其他控制系統(tǒng);

 ? The machine bed adopts the casting piece with the features of good rigidityand small deformation

 ? The headstock is fixed on the feed slide for achieving work feed. The gri.

 ? wheel reciprocatian is also used.

 ? Work feed guideway and gri. wheel worktable guidaway adopt the crossedroller type.

 ? Work feed can be performed by the servo motor through the coupling viahigh-precision ball leadscrew pair.Table reciprocation mavem ent can be achieved by mechanical oscillationwhich its reci speed is adjusted by the freg.-conversion speed reeulator.Cartridge-type work spindle is used, The high-precisian matched spindlebearing is adopted with the features of high rotating accuracy and goodreliability.

 ? Super-wide worktable and feed slide are used, thus improving good rigidity.

 ? It's totally enclosed with guards to prevent swarfs from splashing.

 ? The rear-mounted electrical cabinet and front-mounted control cabinet arealso used, The heat-exchanger in the electrical cabinet is also provided.

 ? The special fixture can also be desiened according to the machined workparts
