歯切工具ブランクに関する FAQ
What are tungsten carbide gear cutting tool blanks?
炭化タングステン gear cutting tool blanks are preformed, near-finished-size carbide bodies used to manufacture gear hobs, power skiving cutters and bevel gear cutting stick blades. After precision grinding and coating, they become finished gear cutting tools for gear machining.
Can you produce custom sizes and tolerances?
Yes. Yatech Materials manufactures gear cutting tool blanks to customer drawings, with custom outer diameters, bores, widths and tight tolerances that support smooth, accurate finish grinding.
Which carbide grades are available?
We offer standard and fine-grain tungsten 超硬グレード with different cobalt contents to match hobbing, shaving and power skiving applications. See our 炭化タングステングレード for detailed specifications.
Do you support small orders and fast delivery?
Yes. We support both small-batch and volume orders with fast lead times. For a quote on custom タングステンカーバイド gear cutting tool blanks, please お問い合わせ — our engineers will reply within 24 hours.
Frequently Asked Questions
Which tool types do your blanks cover?
Gear hob, power skiving and bevel gear cutting tool blanks in standard and custom dimensions.
Can blanks be produced to my shank and bore specs?
Yes — send your tool drawing including bore, keyway and shank tolerances.
Are blanks ground before delivery?
Ground or as-sintered options are available depending on your finishing process.
What is the MOQ and can I order samples first?
There is no fixed MOQ for standard items. Sample orders are welcome so you can verify quality before volume production; shipping is freight collect.
Which grades are available?
We offer ultra-fine and sub-micron 材種 suited to gear cutting tools; our engineers will recommend per your workpiece material.
