YG-1 has the image of solid endmills and solid drills manufacturer, but Cominix also has ER collet chucks from YG-1.
The price is more affordable than the collet chucks made by other companies in Japan, but how is the performance?
Appealing sales point 1: Cost advantage*Comparison of similar size to ER20 by double contact BT40

Length line up of collet chuck made by Japanese manuafcturer A: L=75mm, 90mm, 120mm, 165mm, 200mm, and 250mm
Runout accuracyIt is the runout accuracy at the length for each tool diameter.
Please note that Japanese manufacturers often describe it as diameter to μm.
Comparison test report (YG-1 vs. Japanese manufacture A)
Compared with the collet chuck made by Japanese manufacturer A which boasts the top share in Japan with high runout accuracy.
The purpose is to check that it can be used in ordinary processing and whether it can be used as a cost reduction idea.
Result: Under general processing conditions for general steels, it can be used without much difference from high-performance products.
Tesr report is as follows.
Workpiece clamping condition
Size: 200mm square x 30mm length
YG-1 collet chuck
The runoutis 12μm by general collet
Other manufacturer's collet chuck
(The same size as YG-1)
The runout is 4μm by high precision collet.
→ In side milling, there was almost no difference due to collet chucks compared to Japanese top share manufacturer.
There was a difference as a value, but there were some parts where there was no difference by the measurement position.
→ YG-1 collet chuck could be used without problems even in 0.5D slotting.
