HLCM-15D 15-Head Multi-Function Straight Edge Stone Polishing Machine

PLC Horizontal Edge Grinder | One-Pass Finish · Pneumatic Compensation · Replaces 15 Manual Workers

The HLCM-15D is a heavy-duty PLC-controlled horizontal edge polishing machine for high-volume stone fabrication. It features 15 precision grinding heads, continuous conveyor feeding, and completes rough grinding, fine polishing, back grooving and R-radius forming in a single pass.

 

Built with Taiwan Delta PLC, Schneider inverters and premium industrial components, it delivers consistent edge quality on quartz, granite, marble, microcrystalline and sintered stone. With pneumatic auto-compensation, internal water cooling and automatic thickness adjustment, it eliminates manual polishing defects and matches the output of 15 skilled workers — ideal for countertop factories, stair tread producers and engineered stone plants.

 

Key Benefits

1.  15-Head One-Pass Processing Integrates rough grinding, flat edge polishing, top/bottom beveling, 1/4 & 1/2 R-radius, grooving and safety edging. Switch between straight and radius edges without changing abrasives; supports reserved non-processing sections on individual slabs. .
2. 15-Head Grinding Arrangement

   Station	Spec	Function
   1st Head	4kW, adjustable height/position, Ø150–200mm wheel	Side rough grinding; front/back grooving
   2nd–7th Heads	1.1kW each, pneumatic compensation, sync height	Side flat edge fine polishing
   8th–11th Heads	1.1kW each, pneumatic + oscillating	Bottom edge polishing; small bottom radius
   12th–15th Heads	1.1kW each, pneumatic + oscillating	Top edge deburring & polishing; small top radius

   
3.  Pneumatic Auto-Compensation All polishing heads maintain constant grinding pressure via pneumatic induction, automatically offsetting abrasive wear. Delivers uniform gloss from first to last slab, cuts rework rate below 2%, and uses oscillating polishing for streak-free radius edges.
4.  Smart PLC Control with Remote Support Delta PLC + touchscreen with recipe memory; Schneider inverters, Omron switches. Built-in network connectivity enables remote troubleshooting. Manual/automatic dual modes; supports continuous or intermittent feeding.
5.  Heavy-Duty Build with Premium Parts Geer 97 gear reducer, Jinchengyi RV motors, SKF bearings. Stainless steel covers, sandblasted + powder-coated frame, galvanized slides. Internal water cooling prevents burn marks on thick slabs.
6.  High Throughput, Fast ROI Adjustable speed 0.5–3 m/min; output equals 15 manual polishers under normal operation. Cuts labor and management costs significantly, typical ROI in 6–12 months.
7.  Customizable Configuration Grinding head count is adjustable from 11 to 24, with flexible head layout and wheel specifications tailored to your actual processing needs. Voltage and control language also available for customization.
