Deep Hole Drilling Machines: Types, Key Specs, and How to Choose
Buying a deep hole drilling machine? Here's what actually matters — the types of machines, the specifications worth comparing, and how to match a gun drilling or BTA machine to your parts and production volume.
How Deep Hole Drilling Works: Gun Drilling, BTA, and the Physics of a Straight Deep Hole
How do you drill a hole 100× deeper than it is wide — in a single pass, straight, with no pecking? Here's how deep hole drilling works: the high-pressure coolant, the self-guiding tool, and what separates gun drilling from BTA.
What Is Deep Hole Drilling? A Complete Guide to the Process
What is deep hole drilling? It's the process of making holes whose depth far exceeds their diameter — straight, smooth, and in a single pass. Here's the definition, the three classic methods, and when you actually need it.
The Second Machine: Why Customers Come Back to RuidCNC for Another
The most honest review a machine gets is a second order. Here's what the customers who came back for a second RuidCNC machine had in common — and what that first year really looked like.
The Intersection Problem: When a Deep Hole Has to Meet a Cross-Hole Exactly
An oil gallery that misses its intersection by half a millimeter means a scrapped crankshaft. Here's how we hold the intersection point of angular, intersecting deep holes — and what can go wrong when you don't.
Titanium Doesn't Give Warnings: Taming Heat in Micro Deep Hole Drilling
Titanium is the material that turns confident machinists humble — it holds heat, work-hardens, springs back, and can set its own chips on fire. Here's what it really takes to drill clean, straight micro holes in Ti-6Al-4V, hole after hole.
From One Hole at a Time to Four: When Production Outgrew a Single-Spindle Gun Drill
A customer's deep hole drilling had become the bottleneck holding up their whole line — a tiny Ø2mm hole was taking longer than everything else combined. Here's how moving from one spindle to four changed their throughput without changing the hole.
Fishing a Broken Gun Drill Out of a 500mm Hole: An Emergency Rescue That Saved an Expensive Part
A gun drill snapped 400mm down a 500mm-deep hole — in a forged component worth thousands and with weeks of lead time to replace. Here's how we got the broken tool out without wrecking the hole.
The Sample Part That Saved a Rebuild: Why We Always Ask to Drill Your Part Before Shipping
Two customers, two almost identical orders — one skipped the sample, one didn't. Here's what the sample part caught before it became an expensive surprise, and why we push for it on almost every machine we build.
The Part That Outgrew Gun Drilling: Switching to BTA for a Ø60mm × 1500mm Hole
A customer's deep hole application crossed the line where gun drilling stops making sense — Ø60mm, 1500mm deep, in steel. Here's how we diagnosed the crossover and moved them to a BTA single-tube process without overbuilding the machine.
Four Holes a Day: The Stainless Steel Gun Drilling Problem That Was Burning Tooling
A medical parts supplier's gun drill barely survived four holes in 316L stainless — and every hole was slow. The fix wasn't a new machine. It was getting tool geometry, coolant, and feed right, in ways most people get backwards.
A Machine Called Us at 2 AM: How Remote Diagnostics Kept a Customer's Line Running
An overseas customer's gun drilling machine stopped mid-shift on a Friday night, with a full production line waiting. Here's what 24/7 support actually looks like — and how a video call from our engineer got them running again.
When Standard Machines Won't Do: Building a Custom Solution for Compound-Angle Deep Holes
A plastic mold maker needed cooling channels drilled at compound angles across five faces of one part. No catalog machine fit — so we designed the machine around the part. Here's how a custom build actually happens.
The Hole That Wouldn't Stay Straight: Solving a Deep Hole Drift Problem at 600mm Depth
A hydraulic component supplier was scrapping parts because their 600mm-deep holes kept drifting off-axis — and the drills kept breaking. The fix wasn't a new machine. It was understanding why a twist drill can't be pushed past its limits.
From First Inquiry to Production-Ready: How a RuidCNC Project Actually Unfolds
What really happens after you send us a drawing? Here's the step-by-step journey of a deep hole drilling project — feasibility, quoting, build, run-off test, installation, and the support that keeps going for years.
