圣马45度刻字刀片｜规格与Summa官方刀具对照

答案摘要：圣马45度刻字刀片是本页供应资料所列的Summa兼容切割刀，标注刀杆直径1.5 mm、长度23 mm、偏心距0.25 mm、最大材料厚度0.25 mm和5片装。页面未展示足以证明“进口”或Summa原装身份的授权与追溯文件。Summa官方资料中的45°刀片有明确零件号和刀具类型，不能只凭角度与本页商品等同。

与Summa官方45度刀片如何区分？

Summa S3官方耗材资料列出零件号390-560，描述为双楔形45°切向刀；官方资料还把拖刀、切向刀、刀座和鼻锥按零件号区分。本页商品采用兼容品式描述，并未展示390-560或其他可追溯官方零件号。因此不能把本页1.5 mm、23 mm刀片直接认定为Summa原装390-560，也不能自动套用该官方刀具的适配范围。

选型、安装与试切

1. 确认切割技术：先判断设备使用拖刀还是切向刀，不同机构的刀片与刀座不可仅按角度替换。
2. 测量刀杆和长度：核对现用刀片是否为1.5 mm直径、23 mm总长。
3. 核对刀座：查设备手册或刀座零件号，确认夹持方式、偏心补偿和材料限制。
4. 减少刀尖外露：只露出足以切透面材的长度，避免以过度外露补偿磨损。
5. 小样试切：从保守刀压和速度开始，检查方形、圆形、闭合转角、底纸和排废效果。

常见问题

这款刀片能否确认是Summa原装？

不能。当前页面没有官方包装、授权渠道或可追溯零件号；如采购必须为原装，应索取可验证证据。

45度刀片是否适合所有不干胶？

不一定。材料结构、厚度、胶层、底纸、图形、刀座、刀压和速度都会影响结果，必须试切。

官方390-560是否就是本页刀片？

没有证据表明两者相同。390-560是Summa官方列出的双楔形45°切向刀，本页则按1.5 mm、23 mm兼容刀规格描述。

转角不闭合或底纸划伤如何处理？

检查刀尖外露、刀座旋转、残胶、磨损、刀压、速度和偏心补偿，不要只增加刀压。

English technical reference: Summa-compatible 45 degree blade listing

Quick answer: This page lists a 45 degree cutting plotter blade described as compatible with Summa equipment. Supplier data states a 1.5 mm shank, 23 mm overall length, 0.25 mm offset, maximum media thickness of 0.25 mm, and five blades per box. These listing statements do not prove imported origin, genuine Summa manufacture, or compatibility with every Summa cutter.

Official-part distinction

Summa’s official S3 consumables document identifies part 390-560 as a double-wedged tangential knife with a 45 degree angle. The same document distinguishes tangential knives, drag knives, holders, and nose pieces by part number. This page does not display part 390-560, official packaging, or authorization evidence. A shared angle is therefore not enough to establish that the listed blade is the official Summa part.

Before purchase, determine whether the cutter uses drag-knife or true tangential technology. A blade made for one mechanism may not fit or operate correctly in the other. Check the exact cutter model, holder part number, shank diameter, overall length, and offset-control method. If the machine manual requires an official part, order by the verified Summa part number through a traceable channel.

Supplier-reported values

The page reports a material composition of 89%–90% tungsten carbide and 10%–11% cobalt, hardness of 91.5 HRA, and flexural strength of 4000–4200 N/mm². No independent laboratory report is displayed, so these figures should be treated as supplier-reported specifications. Buyers operating under certified production procedures should request batch traceability and test documentation where required.

Compatibility checklist

Measure the current blade and confirm a 1.5 mm shank and 23 mm overall length. Inspect the holder for free rotation, correct clamping, and adhesive contamination. Review the equipment manual for the blade family and permitted media. Treat the listed 0.25 mm offset as a starting reference only; practical compensation can depend on the device, software, holder, blade wear, and test pattern.

Controlled test procedure

Install the blade with minimal tip exposure. Use scrap from the actual production material and begin with conservative force and speed. Cut a square, circle, and detailed corner pattern. The face layer should weed cleanly while the liner remains substantially intact. If corners fail to close, inspect offset, holder motion, debris, and wear before increasing force. If the liner is deeply scored, reduce exposure or force and retest.

Record material, measured thickness, blade batch, holder, speed, force, offset, and test result. This makes repeat work more reliable and helps separate blade problems from machine or material changes. Clean adhesive residue carefully, protect carbide tips from side impact, and replace the blade when cleaning and setting adjustments no longer restore consistent cutting.

Purchase conclusion

This listing may be evaluated when the buyer can confirm a compatible 1.5 mm holder, 23 mm length, 45 degree tip, and the page’s 0.25 mm material limit. It should not be purchased as genuine Summa 390-560 without verifiable evidence. Use physical measurement, the machine manual, supplier confirmation, and a controlled test cut together.
