-
Precision is built-in, with standard accuracy of ±0.01 mm, ensuring reliable results even at extreme depths.
-
Designed for industries like oil & gas, aerospace, power generation, and heavy equipment, the KDH Series delivers straight, accurate holes in the largest and most demanding parts.
-
With high spindle power, robust construction, and versatile CNC controls, this machine family redefines heavy-duty deep-hole drilling.
-
Compact models like the KPGD-4X and KPGD-8X are engineered for high-speed micro-drilling, with built-in ER-16 spindles reaching up to 30,000 rpm.
-
These machines are perfect for aerospace, medical, and precision manufacturing, producing fine, accurate holes with exceptional repeatability.
-
Both KPGD models handle large workpieces up to Ø1400 mm, with the 8X optimized for even bigger diameters.
-
By contrast, the KCNC-36 provides lower spindle speeds (up to 5,000 rpm) through a belt-driven R-8 spindle, enabling the use of heavier tooling up to 6.6 lbs. This makes it highly versatile for general-purpose deep-hole applications.
-
All three machines share a robust 141.7″ (3600 mm) base length, ensuring rigidity and stable performance.
-
With rapid feed rates and micron-level positioning accuracy, they guarantee repeatable, high-quality results.
-
Models range from compact machines with tables 15–27 in. wide and 59–78 in. long, to heavy-duty platforms with travels exceeding 200 in.
-
Spindle speeds reach 8,000 rpm (optional 10,000 rpm) with belt or gear drive systems, plus taper options including DIN or BT.
-
Accuracy is consistent and reliable, with positioning precision of ±0.0004 in. (±0.01 mm) across the lineup.
-
Motor power scales from 7.5 hp to over 40 hp, supporting table loads from 3,300 lb to 110,000 lb.
-
Tooling capacity covers diameters from Ø0.6 in. to Ø5.9 in. (Ø15–150 mm), while advanced models deliver rapid feed rates up to 3,150 ipm.
-
This combination of high accuracy, spindle versatility, and large workpiece handling makes the KMGD Series ideal for automotive, aerospace, mold & die, and heavy equipment industries.
KDH — General‑Purpose Deep‑Hole Drilling
The Kent CNC KDH Series is purpose-built for deep-hole drilling, combining massive capacity with proven precision. Models range from 3,100 mm up to 12,000 mm drilling depth, supported by rigid ballscrews and wide base spans up to 1,400 mm for maximum stability. With gear-driven spindles offering speeds of 3–30 rpm for large-diameter boring, and auxiliary tool spindles reaching 1,000 rpm (optionally 1,250 rpm), the KDH Series balances high torque with operational flexibility. Workholding includes dual chucks up to Ø630 mm (optional Ø800 mm, 3- or 4-jaw), while workpiece weight capacity extends from 20,000 kg to 120,000 kg on larger models. Standard accuracy reaches ±0.01 mm, ensuring reliable results even at extreme depths. Designed for industries such as oil & gas, aerospace, power generation, and heavy equipment, the KDH Series delivers straight, accurate holes in the largest and most demanding parts, backed by high spindle power, robust construction, and versatile control systems.
KPGD — Precision Micro Gundrilling
The Kent CNC KPGD and KCNC Series deliver precision deep-hole drilling solutions across a range of applications. The compact KPGD-4X and KPGD-8X are engineered for high-speed micro-drilling, reaching spindle speeds of up to 30,000 rpm with built-in ER-16 spindles, making them ideal for fine, accurate holes in aerospace, medical, and high-precision components. Both handle large workpieces up to Ø1400 mm, with the 8X tailored for even bigger diameters. By contrast, the KCNC-36 offers lower spindle speeds up to 5,000 rpm with a belt-driven R-8 spindle, supporting heavier tooling up to 6.6 lbs and offering broader versatility for general-purpose deep-hole applications. All three models share a robust 141.7″ (3600 mm) base length, ensuring rigidity, while rapid feed rates and micron-level positioning accuracy deliver repeatable, high-quality results. Together, the KPGD and KCNC families provide a balance between ultra-precision micro-drilling and flexible, heavy-duty performance for shops with diverse production needs.
KMGD — Multitasking Deep Hole Drilling
The Kent CNC KMGD Series offers a wide range of multi-spindle deep-hole drilling centers designed for precision and productivity.
