Built for 20mm Acrylic, Ready for Anything: How We Configured a CX-1325 CNC Router for a Lithuanian Workshop — June 2026

A Note Before We Begin

Not every client comes to us with a complicated situation. Sometimes the most important thing we can do is listen carefully, ask the right questions, and make sure the machine we recommend is genuinely matched to what the client actually does — not what we assume they do.

Our Lithuanian client in June 2026 was exactly that kind of conversation. Clear requirements, specific materials, defined sheet sizes, and one concern that went beyond the machine itself: what happens after it arrives?

Here is how that conversation became a successful project.

1. The Client's Situation: Clear Requirements, One Critical Concern

The client operates a fabrication workshop in Lithuania. Their production is focused but varied:

Primary work: Acrylic cuttingThe core of their daily production is cutting 20mm thick acrylic sheet — a demanding material that requires both cutting power and thermal management. Acrylic at 20mm thickness is not a job for an underpowered spindle. Too little torque means slow feed rates, heat buildup, and melted or chipped edges. Getting the spindle specification right was the most important technical decision in this project.

Secondary work: Relief engravingThe client also performs 3D relief engraving on an occasional basis — decorative panels, custom signage, and artistic woodwork. While not their primary volume activity, it is a meaningful part of their product offering and needed to be supported by the machine configuration.

Sheet size requirements confirmed:The client provided specific minimum and maximum board dimensions — a detail that matters for fixture planning, vacuum or clamping setup, and confirming that the machine's 1300mm × 2500mm working area covered their full range without repositioning.

The concern that shaped the entire conversation:Beyond the technical specifications, the client was explicit about their primary worry: after-sales service. They had seen other workshops in their region purchase machines from overseas suppliers and then find themselves without support when questions arose — no documentation in a usable format, no responsive technical contact, no practical guidance for operators who had never used a CNC router before.

They were not asking for a vague promise. They wanted to know specifically: what will you actually provide, and when?

We answered that question in detail. And then we delivered on it.

2. The Configuration: Why We Specified 7.5KW Water-Cooled Spindle + Full Servo Motors + Pressure Roller

The CX-1325 platform is the foundation. But the configuration we recommended for this client was specifically engineered around their primary material — 20mm acrylic — and their secondary requirement for occasional relief engraving.

7.5KW Water-Cooled Spindle — The Right Power for 20mm Acrylic

This was the most important specification decision in the project, and it required a clear explanation to the client.

Why not the standard 3KW spindle?A 3KW spindle can cut acrylic — but at 20mm thickness, it must do so at reduced feed rates to avoid overloading the motor. Slow feed rates on acrylic create a specific problem: the bit dwells longer in the cut, generating more heat, which causes the acrylic to soften and re-weld behind the cutting edge. The result is rough, melted cut faces that require significant post-processing — or outright scrap on precision pieces.

Why 7.5KW?The 7.5KW water-cooled spindle provides the cutting force to maintain high feed rates through 20mm acrylic — moving the bit through the material fast enough that heat does not accumulate at the cut face. The result is clean, smooth acrylic edges that require minimal or no post-processing.

Water cooling is essential for this application. Acrylic cutting at production speeds generates sustained spindle heat. Water cooling maintains stable spindle temperature across long cutting sessions, protecting the spindle bearings and maintaining consistent cutting performance throughout the shift.

For the occasional relief engraving work, the 7.5KW spindle provides more than sufficient torque for deep 3D carving on wood and MDF — with the water cooling ensuring the spindle can transition from a full-day acrylic cutting run to an engraving session without any thermal recovery time.

Full Servo Motor System — Precision That Closes the Loop

The standard CX-1325 configuration uses stepper motors — reliable and cost-effective for many applications. For this client, we recommended upgrading to a full servo motor system for two specific reasons:

Closed-loop position feedback: Servo motors continuously report their actual position back to the controller. If the motor encounters resistance — from a dense section of acrylic, a knot in wood, or a rapid direction change — the controller detects any deviation and corrects it in real time. Stepper motors, by contrast, operate open-loop: if they lose steps under load, the machine does not know, and the error accumulates silently in the workpiece.

For 20mm acrylic cutting: Thick acrylic generates significant lateral cutting forces, particularly during profiling passes. Full servo drives ensure that these forces do not translate into positional errors — the cut follows the programmed path precisely, regardless of material resistance variations.

For relief engraving: 3D relief work requires smooth, continuous interpolation across all three axes simultaneously. Servo motors provide the acceleration and deceleration smoothness that produces glass-like 3D surface finishes — the difference between a relief carving that looks machined and one that looks crafted.

Pressure Roller — Secure Material Hold for Full-Sheet Acrylic

The pressure roller is a practical addition that directly addresses a common challenge with large-format acrylic cutting: sheet movement during cutting.

Acrylic sheet at 20mm thickness has significant mass. During profiling passes — particularly when cutting internal contours or near sheet edges — cutting forces can cause the sheet to shift if it is not held securely. The pressure roller applies consistent downward force across the sheet surface, working in conjunction with the aluminum T-slot table's mechanical clamping to keep the workpiece absolutely stable throughout the cut.

For a client whose primary production is 20mm acrylic, this is not an optional accessory. It is a core component of cut quality and dimensional consistency.

3. The After-Sales Commitment: Specific, Documented, Delivered

When a client tells you that after-sales service is their primary concern, the correct response is not reassurance. It is specifics.

Here is exactly what we committed to — in writing, before the contract was signed — and what we delivered:

Commitment 1: Pre-Shipment Operation Video Library

Before the machine left our factory, we produced a structured set of operation and maintenance videos covering:

• Machine startup and shutdown sequence

• Workpiece clamping and pressure roller setup for acrylic sheets

• Spindle speed and feed rate parameter settings for 20mm acrylic cutting

• Z-axis zero setting procedure

• Water cooling system startup, flow check, and daily maintenance

• DSP controller: file loading via USB, axis jogging, program execution

• Common fault codes and first-response troubleshooting steps

• Relief engraving: tool selection, depth parameter guidance, 3D toolpath execution

These videos were delivered to the client digitally before shipment — so their operators could begin learning the machine before it arrived. By the time the machine was installed, the team was already familiar with the startup sequence and basic operation.

Commitment 2: Overseas On-Site Training — Available on Request

For clients who require hands-on support beyond remote commissioning, we offer overseas engineer dispatch — our technician travels to the client's facility for in-person installation, calibration, and operator training.

We made this option explicitly available to the Lithuanian client with clear terms and timelines. They had the choice of remote commissioning via video call, or on-site support if they preferred. Knowing that option existed — as a real, documented offer rather than a vague promise — was a significant part of what gave them confidence to proceed.

Commitment 3: Ongoing Remote Technical Support

Post-installation, the client has direct access to our technical support team via WhatsApp. Cutting parameter optimization for new acrylic thicknesses or grades, relief engraving depth guidance, consumable replacement (bits, water cooling fluid), software questions — we treat ongoing support as part of the product delivery, not a separate service.

4. Quality Inspection: Verified Before a Single Video Was Filmed

The operation videos we send to clients show a machine that has already been fully inspected and verified. Our pre-shipment QC for this configuration covered:

• Frame geometry: Gantry squareness and rail parallelism verified across full working area

• Servo system test: All three axes run through positioning accuracy test patterns — closed-loop feedback confirmed on each axis

• Spindle performance: 7.5KW spindle run-in at progressive speeds to 24,000 RPM; water cooling flow rate and temperature stability confirmed; no vibration or noise anomalies

• Pressure roller function: Roller height adjustment range confirmed; downforce consistency verified across full Y-axis travel

• Acrylic cutting test: Full-depth cut through 20mm acrylic sheet at production feed rate — cut face quality, edge smoothness, and dimensional accuracy recorded on video

• Relief engraving test: 3D relief toolpath executed on MDF — surface finish and depth accuracy confirmed

Both test videos — acrylic cutting and relief engraving — were sent to the client before packaging began. The client reviewed and approved both before we proceeded to pack.

6. The Value We Delivered

7. What This Case Means for Workshops Like Yours

✅ Spindle power for acrylic is not about cutting through it — it is about cutting through it cleanlyAny spindle can cut 20mm acrylic if you slow down enough. The problem is that slow feed rates cause heat buildup, which melts and re-welds the acrylic behind the cut. A 7.5KW spindle cuts fast enough to stay ahead of the heat — and the result is a smooth, clean edge that needs no post-processing. If you are cutting thick acrylic and your edges are rough or melted, spindle power is the first thing to check.

✅ Full servo motors are the right choice when material resistance variesAcrylic is not a homogeneous material — density and hardness can vary across a sheet, and cutting forces change with direction. Stepper motors cannot detect or correct for these variations. Servo motors can. If your current machine loses accuracy during aggressive acrylic profiling passes, the drive system is likely the cause.

✅ A pressure roller is not optional for large-format acrylic workLarge acrylic sheets are heavy and smooth — they can shift during cutting even when clamped. A pressure roller eliminates this variable, keeping the sheet stable throughout the cut and ensuring that dimensional accuracy is maintained from the first pass to the last.

✅ After-sales support should be documented before you sign — not promised afterAsk any supplier you are evaluating to put their after-sales commitments in writing before you sign the contract. What videos will they provide? When? What does remote commissioning cover? Is on-site training a real option? If the answers are vague, that tells you what to expect when you actually need help.

✅ Pre-shipment operation videos change the installation experienceA client whose operators have watched the startup sequence, the parameter setup, and the first-cut procedure before the machine arrives is a client who installs faster, makes fewer errors, and reaches full production sooner. This is not a luxury — it is a practical investment in a successful commissioning outcome.

Final Thoughts

This Lithuanian project was, in many ways, a straightforward one. The client knew what they needed to cut, they knew the size of their sheets, and they had a clear concern about support. Our job was to listen carefully, configure the machine correctly, and then back it up with the after-sales commitment they needed to feel confident.

The 7.5KW water-cooled spindle cuts their 20mm acrylic cleanly. The full servo system keeps every cut accurate. The pressure roller keeps every sheet stable. And the operation video library meant their operators were ready before the machine even arrived.

That is what a well-matched machine and a committed supplier look like together.

If your workshop cuts thick acrylic, does decorative relief work, or simply needs a supplier who will still be there six months after delivery — let's have a real conversation.
