Grooving and punching balsa, PVC and PET core materials

Grooving and punching are distinct core material processing operations. OMAC lists the FNJ1300-2 for shallow grooves in balsa wood, PVC and PET, and the MZ2500-4 for punching those materials and acoustic panels. Select the machine around the required groove or hole pattern, panel size and material behavior.

FNJ1300-2 shallow grooving

The FNJ1300-2 catalog describes two sets of saw shafts, A and B, with PLC and touch screen control for saw blade lifting and automatic positioning. It also describes platform adsorption for plate fixation and belt conveying.

The page lists:

• Processing plate size: 1280 × 1280 mm.
• Maximum panel thickness: 70 mm.
• Shaft spacing: 20 mm.
• Sawtooth thickness: 1.8 mm.
• Groove spacing: 20 ± 2 mm.
• Groove width: 2 ± 0.5 mm.
• Groove thickness, as worded in the original catalog: 2 ± 0.5 mm.

The original use of “groove thickness” should be clarified with OMAC against the required machining drawing. Do not assume that a translated catalog term resolves the final depth or geometry requirement.

MZ2500-4 CNC punching

The MZ2500-4 page lists four drill rows, 22 kW installed motor power and hole spacing of 20 × 20 mm or 40 × 40 mm. Maximum working dimensions are 1220 mm wide, 2500 mm long and 60 mm thick.

MZ2500-4 — catalog-listed four-row punching equipment.

The catalog lists an overall machine size of 3550 × 1800 × 1750 mm and a weight of 4800 kg. Layout, handling and installation needs should be confirmed separately.

What to confirm for your material

Provide the precise grade or density of the core material, dimensions, desired pattern, machining drawing and sample condition. Ask about the specified setup, tooling and clamping or adsorption approach for that material.

This guide identifies documented equipment applications. It does not establish laminate performance, resin compatibility, wind blade certification or a guaranteed production outcome. Those require the relevant engineering assessment and material validation.

Connect the application to the process

OMAC places these models in its wind energy equipment collection. That describes the equipment category; grooving and punching can be discussed for the catalog-listed materials according to your actual project.
