CIR Parvae Pressionis DTH Ferramenta — Imagines e Operis Metallicis

A customer operating CIR hammers on a mining project sent us these photos. Low-pressure DTH drilling, mixed ground conditions, production work. The bits had completed their service life and were ready for replacement — so they took a few pictures before replacing them.

KAIQIU CIR DTH bit — spline end

CIR bits have existed for decades. They are simple, reliable, and operate using the low-pressure air already available at most job sites — 0.5 to 1.0 MPa, nothing fancy. That is why they remain widely used: water wells, mining, quarrying, construction. The design has changed little over the years, but the difference between a good CIR bit and a mediocre one still lies in the details.

What the Photos Show

Three shots, three angles telling the same story — bits that performed their function and wore out correctly.

Visus frontalis (prima photographia). Omnes butones carburi sunt adhuc in loco. Nulli inserti evulsae, nullae marginis fractae. In bit DTH pressionis infimae, amissio buttonis saepe problema est soldaturae. — Calor ab aere generatus non sufficit ut fissuras thermicas per se causet. Omnis abrasio in superficiebus operativis est, ubi esse debet.

Comparatio collateralis (secunda photographia). Duo bits eadem ex serie, eodem saxo, simili metratura. Abrasio inter eos constans est. Haec res in foraminibus productivis magni momenti est: nam si unus bit 200 metra durat, alter autem 80, programma foraminis perturbatur. Constantia inter bits significat clientem scire quid expectare debeat.

Extremitas splinii (tertia photographia). Splinia motus quae cum malleo coniunguntur sunt abrasa sed integra. — Nullae fissurae ad radices spliniorum, nulla deformatio quae bit in malleo impediens esset. Passagia aeris sunt pura. Bit adhuc libere rotabat cum extractus est.

CIR Bits — Quod Reapse Importat

Categoria CIR est plena. Omnes fornitorēs eās habent. Sed tria rēs distinguunt ferrum quod forat et ferrum quod bene forat:

Gradus carbīdis et sedēs. Quia ferrī CIR in pressiōne aēris parvā operantur, velocitās lavātiōnis minor est quam in malleīs altius pressiōnis. Fragmenta plus tempus in proximitāte faciēs ferrī manent, quod plūs abrasionis in butōnibus et in corpore significat. Gradus durior carbīdis adiuvat, sed tantum si iūnctūra braze fortis satis est ut butōnem in locō teneat. Nimis durum et butōnēs franguntur sub impetū — nimis molle et cito abrāduntur. Hanc aequilibrīum in applicationibus pressiōnis parvae obtinēre est pars difficilis.

Resistentia corporis ad abrasionem. Corpus ferrī percutitur duābus viīs — impetū pistōnis et abrasiōne fragmentōrum quae circum eum vortēbantur. Si ferrum mollis est, corpus abluitur et butōnēs sustentātiōnem amittunt. Si nimis durum est, frangitur. Ferrī in his imaginibus ostendunt abrasionem corporis sed nōn ablūtiōnem — gradus ferrī et tractātus calōris erant perfectī.

Commentārius clientis

The driller told us: "We run CIR hammers because our compressor can't push high-pressure. Some suppliers' bits lose buttons after a couple of shifts. These lasted a full rotation. We are ordering another batch."
