We serve clients worldwide. By collaborating with international partners, we also implement projects outside of Europe. We support our clients both on-site and via remote access.

We are a Swiss company specializing in the modernization (retrofit), service (diagnostics, repair, spare parts), and automation of precision grinding machines – particularly HAUSER jig grinding machines. Additionally, we develop custom software solutions for machine tools with FANUC controls and automation systems, and we distribute internal and external cylindrical grinding machines that are precisely tailored to our customers' requirements.

We are based in Switzerland, near Biel/Grenchen – right in the heart of the Swiss machinery industry. Our workshop and offices are located in Arch (BE) and are centrally situated, directly on the A5 motorway, making them easily accessible for customers both domestically and internationally.

Yes. Equipment, software, automation, hydraulics, measurement systems, color, and options can be individually defined.

Yes. We replace older CNC, NC, or PLC controls and handle the complete integration, parameterization, and commissioning.

In most cases, yes. Minor modernizations can also be performed on-site.

1. Analysis of the existing machine

2. Proposal with technical concept

3. Modification & Modernization

4. Commissioning & Training

Depending on the scope, between 8-12 weeks and several months. After our assessment, we will provide you with a binding timeline.

That depends on the condition. Upon request, we overhaul guides, spindles, ball screws, and bearing seats, or measure and correct geometric errors.

Yes. The scope and duration depend on the project content and components.

A retrofit utilizes the machine's high-quality mechanical base and combines it with modern control and measurement technology.

‍

The result: Precision comparable to a new machine, yet more cost-effective.

We use new FANUC CNC controls, such as FANUC 0i-F Plus or 30i-B Plus, including custom software with functionality as required.

FANUC has a global sales and spare parts network. Spare parts are available for at least 25 years – a clear advantage over other control manufacturers and perfectly matched to the long service life of the machine.

Our integrations include:

• Renishaw OMP400 measuring probe system
• Structure-borne sound sensors for process monitoring and avoidance of idle grinding
• Digital process analysis with live display and reporting
• Dressing systems for cylindrical and profile grinding wheels.This makes the grinding process measurable, adaptive, and reproducible.

Yes. Our software is compatible with older control generations, including well-known bore and contour grinding cycles such as: G100, G105, G140, etc. After modernization, existing programs from machines with FANUC controls can largely be reused without modification. This reduces conversion effort and training times.

Yes. Our controllers support:

• Data logging and process recording
• NC program exchange via network
• Machine connectivity according to Industry 4.0 / OPC-UA
• Remote service and remote monitoring

Yes. We can source many suitable components, overhaul them, or replace them with compatible parts.

Maintenance contracts are optimally tailored to customer needs. We offer training, especially for machines with FANUC control. Our operator training covers general machine operation, grinding cycle programming, workpiece setup, taper grinding, Renishaw probes, acoustic emission systems, rotary swivel axes, and much more. Naturally, we will work out customer-specific maintenance contracts for you in detail.

Yes. We develop HMI interfaces, macros, grinding cycles, and automation logic that are precisely tailored to your workpieces, machine configuration, and manufacturing processes. Our software is specifically designed for jig grinding.

Yes. We handle disassembly, transport coordination, reassembly, alignment, re-measurement, and commissioning. This applies to machines revised by us as well as machines in their original condition.

Yes. We offer fully reconditioned HAUSER machines that are mechanically rebuilt and equipped with new FANUC controls. If you do not have a suitable machine for reconditioning, we will organize an appropriate base machine for your application profile.

Upon request, we can perform a complete machine exchange: Your existing machine is dismantled, directly replaced by the reconditioned machine, and taken in as a trade-in. The traded-in machine is then reconditioned and modernized for another customer.

‍

This enables:

• Minimal downtime
• Predictable costs
• Sustainable utilization of existing machine assets

Yes. Together with our partner DragsTec, we analyze and optimize grinding processes directly at the customer's site. This includes, among other things, adapting dressing strategies, feed rates, infeed, tool selection, cooling, and NC sequences to the specific machine and workpiece requirements.

Thanks to this tailored process optimization, processing times can be significantly reduced – in many cases by up to 50% – while simultaneously achieving higher form accuracy and repeatability.

Yes. Through remote diagnostics, we can analyze and fix many errors without a technician needing to be on-site. This reduces response times and minimizes downtime. This is only possible if a control system is equipped with a PC (min. Windows XP with SP3). All machines modernized by Esoma are equipped with remote support as standard.

After the mechanical overhaul, the machine's axes are measured using laser interferometry. This measurement is carried out in collaboration with our partner Kuenz precision AG, an independent, external measurement facility with regularly calibrated measuring equipment (traceability according to ISO 17025).

‍

The geometric inspection of the axes and guideways is carried out in accordance with the applicable ISO and VDI standards for machine tools, including:

• ISO 230-1 / ISO 230-2 – Testing of the accuracy of machine tools
• VDI/DGQ 3441 – Repeatability and positioning accuracy

‍

All measured values are logged, traceably documented, and handed over to you upon machine acceptance. This provides you with neutral, standard-compliant proof of axis accuracy and machine geometry.

Depending on its condition, the machine is completely disassembled, cleaned, measured, and rebuilt. All wear parts are replaced: scraped guides, bearings, spindles, measuring systems, pneumatics, wiring, CNC control, control cabinet, etc.

Yes. The user interface is touch-optimized and is available in German, English, French, and other language versions. This also includes fonts and character sets with extended character encodings (e.g., Chinese (simplified & traditional), Japanese, or Cyrillic).

The interface is structured so that users who have previously worked with older control systems can transition quickly and without extensive training.

All cables and sensors are replaced with modern technology. Additionally, a new, space-saving control cabinet is installed. The electrical concept is designed so that no special electronics are required. This allows the machine operator to largely maintain the machine themselves using standard components or FANUC spare parts, which are available for at least 25 years.

Hand scraping is a purely manual process for the perfect geometric alignment of guideways. This creates micrometer-precise contact points, guaranteeing maximum precision and longevity.

We support both older and newer HAUSER machines, regardless of whether they have been modernized by us or are still in their original condition.

‍

This ensures that both existing machines and newer models can be operated precisely, stably, and productively over the long term.

Essentially, all machine models with increasing electrical or mechanical problems.

‍

Particularly older machine models, such as S3-DR, S3-111, S3-211, S3-311, S3-314, S40-DR, S40-111, S40-311, S40-314, S50-DR, S50-311, S50-314, S50L-311, S50L-314, S35-311, S35-400, S35-600, S40-400, S40-600, S45-400, S50-400, S50-600, S50L-400, S50L-600.

Old machine frames have naturally stabilized and become stress-free over many years. New machines are often built without long material settling periods. This means that carefully overhauled old frames are more stable and dimensionally accurate than many new machines.

No. The CAM system runs directly on the machine. Optionally, a desktop version can also be used. The software is only available as a desktop license.

3D models (e.g., STEP per ISO 10303) are imported. Holes, contours, planes, and machining surfaces are automatically recognized and linked to a grinding or machining process.

A multi-contour toolpath can often be created in 1–2 minutes with approximately 15 clicks. The NC program is immediately ready – no corrections required.

The user clicks on a contour in the model – the system automatically generates all steps: measuring, dressing, grinding, compensation, and process parameters. No manual NC programming is necessary.

J-Grinder is a CAD & CAM system specifically developed for coordinate grinding that automatically generates NC programs – without manual post-processing.
