KULA CNC Horizontal Honing Machines are designed for high-precision internal bore finishing of small and medium-sized components that require stable stroke movement, accurate dimensional control and consistent surface quality. With CNC automation, horizontal workpiece support and flexible honing parameter adjustment, these machines help manufacturers improve bore accuracy, surface finish and production repeatability.
Compared with a CNC Vertical Honing Machine, a CNC horizontal honing machine is more suitable for parts that need horizontal support, side loading or stable stroke movement during the honing process. For long bore components, hydraulic cylinders or crankshaft bore finishing, you can also compare KULA’s CNC Deep Hole Honing Machine series. As part of KULA’s CNC Honing Machine product line, horizontal honing machines are widely used in automotive, aerospace, machine tool and precision parts manufacturing.
The HM Series CNC Horizontal Honing Machine is engineered for precision finishing of small components, including automotive parts, connecting rods, stators, gears, guiding sleeves and machine tool components. It is suitable for manufacturers that require high surface quality, tight bore tolerance and repeatable machining results in batch production.
This series features dual inverter control, automatic stone wear compensation, touchscreen numerical control and an enhanced stroke drive system. The spindle and stroke movement can be controlled independently to improve process stability, while the automatic compensation function helps reduce downtime caused by honing stone wear. For production lines that process multiple small precision parts, the HM Series offers a flexible and efficient CNC horizontal honing solution.
A CNC horizontal honing machine is often selected when workpieces are easier to support in a horizontal position or when stable reciprocating stroke movement is required. It is especially suitable for small precision parts that need accurate bore size, improved cylindricity and smooth internal surface quality after drilling, boring or reaming.

KULA CNC horizontal honing machines are suitable for parts that require high internal bore precision, stable surface finish and reliable production consistency. The HM Series can be used for many small and medium-sized components across precision manufacturing industries.
Automotive parts: engine components, gears, hydraulic valves and transmission-related parts
Connecting rods: precision bore finishing for small and medium connecting rod components
Stators: internal bore finishing for motor and machine components
Gears: accurate internal hole finishing for gear parts
Guiding sleeves: smooth and accurate bore processing for guide and sleeve components
Machine tool parts: small precision components requiring stable dimensional control
CNC horizontal honing machines are widely used in industries where internal bore accuracy directly affects assembly performance, service life and product stability. They are especially valuable for manufacturers that need repeatable bore finishing in high-volume or multi-variety production.
Automotive manufacturing: used for precision automotive parts such as gears, connecting rods, hydraulic valves and engine-related components.
Aerospace manufacturing: suitable for small high-precision parts requiring tight tolerances and reliable surface quality.
Machine tool manufacturing: used for small intricate components that require stable internal bore finishing and consistent geometry.
Hydraulic components: suitable for valves, sleeves and related components requiring smooth bore surfaces and reliable fit.
Precision parts production: ideal for batch production of small parts with repeated bore accuracy requirements.
The dual inverter system independently controls spindle and stroke movements, helping the machine maintain stable honing conditions for different workpieces. This is useful for improving process consistency and surface finish quality.
During long production cycles, honing stone wear can affect processing stability. The automatic stone wear compensation system helps maintain consistent honing performance and reduces the need for frequent manual adjustment.
The intuitive numerical control system allows operators to adjust honing parameters more efficiently. This helps reduce setup time when switching between different workpieces or bore requirements.
The double-guide stroke bracket and upgraded connecting rod drive system support stable reciprocating movement and improved machining efficiency, especially for small parts that require repeatable finishing quality.
KULA can provide different horizontal honing rods, honing stone push plates, tool connectors, multi-stone honing rods and honing stones for different hole structures, including key slot holes and keyless slot holes.

| CNC Horizontal Honing Machine | Small precision parts and horizontally supported components | Connecting rods, gears, stators, guiding sleeves and automotive parts | Convenient loading, stable stroke movement and flexible processing |
| CNC Deep Hole Honing Machine | Long bore, hydraulic cylinder and crankshaft applications | Hydraulic cylinders, crankshaft bores, aerospace parts and heavy machinery components | Long machining length, deep bore accuracy and strong cooling performance |
A CNC horizontal honing machine is recommended when the workpiece is better supported horizontally, when small precision bores need stable stroke movement, or when the operator needs convenient side loading and flexible parameter adjustment. It is a practical choice for high-precision parts that require smooth internal surfaces and consistent bore dimensions.
Choose horizontal honing when workpieces are easier to locate or clamp horizontally
Choose it for small parts such as connecting rods, gears, stators and guiding sleeves
Choose it when production requires frequent parameter adjustment for different parts
Choose it when automatic stone wear compensation is needed to reduce manual correction
Choose it when the goal is to improve internal bore finish after boring, drilling or reaming
If your workpieces are cylinders, engine blocks or vertically loaded components, a CNC Vertical Honing Machine may be more suitable. If your project involves long bores, hydraulic cylinders or large deep-hole parts, you can choose a CNC Deep Hole Honing Machine.
Different workpieces require different honing tools, fixtures, stroke settings and machining processes.
