2007年6月25日，日立電動(dòng)工具公司宣布推出其使用UVP技術(shù)的低振動(dòng)往復(fù)鋸，這種鋸可以減少電機(jī)振動(dòng)，明顯減少用戶疲勞成度。CR13VBY往復(fù)式鋸具備獨(dú)特的回轉(zhuǎn)切割裝置，和用于最終控制的變速轉(zhuǎn)盤(pán)和板機(jī)，以及所有包裝在一個(gè)輕量級(jí)和環(huán)境改造工具里的主要級(jí)切削速度級(jí)。 　　所推出的CR13VBY帶有傳統(tǒng)往復(fù)式鋸的特點(diǎn)，但是，拉動(dòng)扳機(jī)之后就與傳統(tǒng)的一點(diǎn)都不一樣。日立取得專(zhuān)利的UVP技術(shù)統(tǒng)一了平衡物機(jī)制，這種機(jī)制可減少全負(fù)荷三軸振動(dòng)的65％，明顯減少了轉(zhuǎn)移到用戶的振動(dòng)。12Amp電機(jī)由于其功率可達(dá)1370瓦可提供強(qiáng)大的電力供應(yīng)，帶來(lái)了更快的切割速度和高速有效的工作效率。CR13VBY還安裝了變速轉(zhuǎn)盤(pán)和板機(jī)。這就使得用戶可根據(jù)工作條件優(yōu)化地調(diào)整切割速度，浪費(fèi)很少的物料達(dá)到更好的控制。 　　另一個(gè)來(lái)自日立低振動(dòng)往復(fù)鋸的獨(dú)特優(yōu)點(diǎn)是雙模式切割裝置。用戶可為某一種應(yīng)用決定切割方式或“旋轉(zhuǎn)切割”行為，這樣產(chǎn)生的回彈影響明顯少于傳統(tǒng)的軌道方式所產(chǎn)生的回彈，并能節(jié)省木料。CR13VBY還能提供一個(gè)較小的工具刀片。刀片可根據(jù)方便需要即可被插入在上端也可被插入在下端（不包括擺動(dòng)切割模式）。其可以0-3,000 SPM速度傳輸1-1/4的行程長(zhǎng)度。這也可歸因于快速的切割性能。 　　這種低振動(dòng)往復(fù)鋸被設(shè)計(jì)有三倍封條，用于保護(hù)來(lái)自在使用期間產(chǎn)生的大量灰塵和碎片，同時(shí)保護(hù)其在切割成小管時(shí)免于被水污染。耐用的前蓋由雙模彈性塑料制成，用于阻止熱傳遞和滑動(dòng)。其人造外形和絕熱把手很容易操作，使得CR13VBY使用一整天感覺(jué)也很舒服。 　　由于其有5年保證期，CR13VBY低振動(dòng)往復(fù)鋸是切割管道、木材、金屬如軟鋼、鋁和銅的理想選擇，和各種各樣的合成的材料，如bakelike和氯乙烯質(zhì)地的材料。關(guān)于更多信息，包括日立的產(chǎn)品和服務(wù)，請(qǐng)與日立電動(dòng)工具公司聯(lián)系（1-800-829-4752）或登錄網(wǎng)址：www.hitachipowertools.com original text [COLOR=#708090]Hitachi Introduces a Low Vibration Reciprocating Saw Featuring User Vibration Protection （UVP） Technology NORCROSS, GA., June 25, 2007 – Hitachi Power Tools today unveiled its first low vibration reciprocating saw featuring User Vibration Protection （UVP） technology that reduces motor vibration and significantly decreases end user fatigue. The CR13VBY Reciprocating Saw features a unique swing cutting mechanism, variable speed dial and trigger for ultimate control and class leading cutting speed all packaged into a lightweight and ergonomic （9.7 lbs） tool. Pick up the CR13VBY and it appears to be a conventional reciprocating saw. But, pull the trigger and there is nothing conventional about it. Hitachi’s patented UVP technology incorporates a counterweight mechanism that reduces full-load tri-axial vibration by over 65% significantly reducing vibration transfer to the user. The 12Amp motor provides aggressive power thanks to 1370 Watts, resulting in a faster cutting speed and higher efficiency on the job. The CR13VBY is also equipped with a variable speed dial and trigger. This allows the user to adjust the cutting speed optimally for the working conditions and material for less waste and more control. Another unique feature on this low vibration reciprocating saw from Hitachi is the 2-mode cutting mechanism. The user can decide between straight cutting mode for certain applications or a “swing cut” action that produces significantly less rebound effect as compared to traditional orbital action for a more efficient cut in wood materials. The CR13VBY also offers a tool-less blade change so blades can be quickly mounted and replaced with a simple press of a lever. The blades can be inserted in either direction- upward or downward （except in swing cut mode） for convenience if the application applies. It delivers a stroke length of 1-1/4” at 0-3,000 SPM that also attributes to its rapid cutting performance. This low vibration reciprocating saw is constructed with a triple seal design to protect from the large amounts of dust and debris that is generated during use as well as to protect it from water waste when cutting into pipes. The durable front cover is made from double molded elastomer and plastic to protect from heat and prevent slippage. Its ergonomic shape and slip/heat resistant grip are easier to handle and make the CR13VBY comfortable to use all day long. And with Hitachi’s industry leading 5-year warranty, the CR13VBY low vibration reciprocating saw is ideal for heavy use to cut pipes, wood, metals such as mild steel, aluminum and copper, and various synthetic materials such as bakelike and vinyl chloride.
