產(chǎn)品詳細(xì)介紹

類型：替換式系列
Type: Interchangeble live center
負(fù)荷：中
Duty: Medium

適用：CNC車床、高速車床及其他機(jī)床。

Application? CNC lathe and high speed lathe or other lathe machine.

用途：適用長度400mm以內(nèi)一般軸心車削加工。

Working Usage : Applicable for the length less than 400mm ordinary turning process.

結(jié) 構(gòu)：軸承徑向力和軸向力分開設(shè)計，採用雙列滾珠精密軸承、止推軸承、滾針軸承排列製成。

Structure? The radial load and axial load designed separately. Combination of double row ball bearing and thrust bearing and needle bearing.

選配：SC-61-M-3A/4A/5A; Y型扳手、61型中子、61型沖子

Accessories: For SC-61-M-3A/4A/5A, Y spanner and 61 type Tips and 61 type pin punch.

精準(zhǔn)度：0.005以內(nèi)

TIR? Less than 0.005mm

檢測頂尖的尖部跳動精度時，必須在頂尖頂緊工件的狀態(tài)下進(jìn)行打表。

Inspecting the run out accuracy of the center tip must be under the status of holding the workbar tightly.

另有同規(guī)格輕負(fù)荷（S型，無螺帽），可改善細(xì)長工件易變形問題

There is S model of light duty type, same spec, which can improve the issue of deformation of processing slender workpiece

Remarks
1,For the lubricating oil,SKF-LGMT2 is designated,others aren't allowed
2,if "A" is behind the center model name,it denotes a draw-off nut attached.
3,About radial force data, please refer to workpiece weight and machining force.
4,if "A" is behind the center interchangeable tip name,it denotes the tip is extended length.
5,About axial force data, please refer to the hydraulic pressure data of the tailstock.
6,For live centers, SKF lubricating oil is designated, it is waterproof.
7,Customized order can be accepted.
8,Subject to technical changes.
