Full Name: HLSQ-400 Plus 4+1 Axis PLC Bridge Saw

Brand: Hualong Machinery

HLSQ-400 Plus PLC bridge saw equipped with retractable 5.5kW high-speed spindle up to 24000rpm. It handles slab cutting, fixed 45° mitre cuts, sink cutouts, edge milling and grooving in one setup for kitchen & bathroom stone countertops.

The HLSQ-400 Plus is a 4+1 axis PLC-controlled bridge saw, featuring a high-speed motorized spindle for multi-functional processing. It is designed specifically for the fabrication of countertops made from marble, granite, sintered stone, and engineered quartz.

Unlike standard bridge saws equipped only with a saw blade, the HLSQ-400 Plus utilizes its saw blade for cutting slabs and shaping outlines, while its motorized spindle handles tasks such as sink cutout, grooving, edge trimming, and milling. This machine covers the entire fabrication process for stone countertops.

Positioned between standard 3-axis bridge saws and high-end 5-axis bridge saws, this machine offers a one-stop solution for countertop fabrication, combining high cost-effectiveness with ease of operation.

Its primary target customers include stone countertop fabricators, small-to-medium-sized stone processing plants, monument/tombstone manufacturers, and stone export-oriented enterprises.

Saw Blade (15kW main motor, Φ350–400mm saw blade):

Capable of straight-line cutting of large slabs, 45° miter cutting for countertop joints, profile cutting, and curved-contour cutting. The saw blade can tilt 45°, allowing for edge chamfering and mitered-edge processing in a single pass. Offers high cutting efficiency.

5.5 kW High-Speed ​​Electric Spindle Unit:

Designed for cutting sink and faucet openings, milling grooves in countertops, trimming edge profiles, and slotting panels. This eliminates the need to transfer workpieces to separate machines for cutting or edge milling, thereby reducing positioning errors caused by repeated handling and re-clamping, while also saving processing time.

Multi-angle cutting:

The machine head rotates 360°, the saw blade tilts 45°, and the worktable tilts from 0° to 85°-allowing for seamless switching between straight cuts, miter cuts, and bevel cuts.

Simple operation, preset graphics library

Includes preset templates for polygons, circles, ellipses, and countertops; operators simply enter the dimensions-no professional CNC programmer required.

Equipped with a Panasonic PLC industrial control system for superior stability.

Structurally stable

The machine features a 4,500 kg heavy-duty bed and utilizes precision linear guides for X/Y/Z-axis transmission, ensuring stable cutting and high cutting accuracy.

Replace multiple machines to win more orders.

Traditional process: slab cutting → sink hole drilling → edge profiling.

HLSQ-400 Plus completes all jobs with saw blade + electric spindle in one clamping. Fabricators can accept complete kitchen countertop orders for higher profits, lower equipment investment and less floor occupation.

Many countertop fabricators lose bids because they cannot offer fully finished countertops in-house. This machine removes that limitation.

You no longer need to outsource sink cutouts or edge profiling to third parties, which eats into your profit and creates quality & scheduling risks. All finished countertop work stays within your own workshop.

It gives you greater control over quality and delivery timeline. You can quote faster, promise tighter lead times and win more high-value countertop contracts against competitors who only offer slab cutting.

Investing in HLSQ-400 Plus is a direct way to expand your service offering, strengthen your competitiveness and increase your profit margin on every countertop job.
