How a short-stroke honing machine works

The short-stroke honing machine is a specialized machine tool for high-precision fine machining of bores. It is used when the highest demands are placed on dimensional accuracy, surface quality, and dimensional stability. The term "short-stroke honing machine" refers to the short, oscillating stroke of the honing tool, which rotates and moves axially in the bore at the same time.

Short-stroke honing Definition

In short-stroke honing, material is removed by fine abrasives applied to the honing tool. These abrasive particles remove microscopic layers of material from the bore surface. What makes this process special is the simultaneous superimposition of turning and reciprocating movements in very short amplitudes – typical stroke lengths are only a few millimeters at high frequencies. This results in a very uniform and cross-hatched surface with defined contact areas.

The short-stroke honing machine is usually CNC-controlled and can operate several machining units simultaneously. It is capable of maintaining the tightest tolerances in the range of a few micrometers. Typical applications include the reworking of bearing bushes, cylinder bores, injection components, or hydraulic housings. Geometric errors such as ovality, taper, or waviness can be corrected through targeted material removal.

Thanks to state-of-the-art measurement technology, the machine can measure and automatically correct during or after the honing process. This ensures maximum process reliability and repeatability. The use of special coolants and lubricants also minimizes thermal stress, which has a positive effect on dimensional accuracy.

Advantages and disadvantages of short-stroke honing

Short-stroke honing enables extremely high dimensional and shape accuracy as well as very fine surfaces with a defined structure. Even the slightest geometric errors such as ovality or conicity can be corrected precisely. In addition, material removal is minimal and controlled, which is ideal for fine machining.

Disadvantages include the relatively low removal rates, which make it unsuitable for rough pre-machining, and the higher investment costs for machines and tools. The process is also more complex and requires special expertise and suitable operating resources such as high-quality cooling lubricants and measuring systems.

Design of a short-stroke honing machine

A short-stroke honing machine consists of the machine frame, one or more honing spindles with short-stroke mechanics, a CNC control system, and automated workpiece clamping systems. In addition, there are integrated measuring devices for process control, a cooling lubricant circuit with a filter system, and tool changing systems for various honing tools. Depending on the design, the machine can also be equipped with automation units such as robot cells or palletizing systems to enable unmanned series production. The machine is usually modular in design so that it can be adapted to different workpiece geometries.

Applications in industrial manufacturing

Short-stroke honing machines are used wherever maximum precision is required for drilling. They are particularly common in the automotive industry, mechanical engineering, aerospace, and the hydraulics and pneumatics sectors. Typical areas of application include engine manufacturing, gearbox construction, and precision components for pumps and valves.

Examples of workpieces that are machined with short-stroke honing machines include:

• Cylinder liners
• Injection nozzles
• Hydraulic cylinders
• Bearing housings
• Valve guides
• Gearbox housings
• Bushings for camshafts
• Precision sleeves
• Compressor housings
• Control bores for high-pressure systems

Applications such as cylindrical implant components can also be found in medical technology. The extremely high surface quality that can be achieved with short-stroke honing machines reduces friction losses and significantly increases the service life of the components.

What is the difference between short-stroke honing and long-stroke honing?

The main difference between short-stroke and long-stroke honing lies in the length of the axial feed stroke; see the section on long-stroke honing.

Tools for a short-stroke honing machine

High-precision honing tools are used in short-stroke honing machines. These include:

• Honing strips
• Diamond or CBN-coated grinding stones
• Expansion sleeves
• Honing heads with adjustable carriers
• Single-lip honers
• Honing heads with multiple strips
• Grinding sleeves
• Polishing tools
• Fine finishing strips
• Workpiece holding inserts
• Centering mandrels

The selection depends on the material, bore diameter, and desired surface finish. Special tools with integrated measuring systems are often used to enable inline corrections during the honing process.

Accessories and operating materials for a short-stroke honing machine

Operating resources include high-performance cooling lubricants, specially designed filter systems for honing oil, tool holders, clamping devices, and workpiece holding units. Equally important are automatic measuring systems for inline quality control, cleaning systems for workpieces, and tool presetting devices. Robotic cells, palletizing systems, or feed devices can be used on the machine for automation. In addition, wear parts such as honing strips, seals, and guides are required on a regular basis. Precise control technology and software for process monitoring round out the accessory package.
