The HKB-21500C is a gantry-fixed, trolley-moving, double-blade edge trimmer driven by full-electric microcomputer control. Steel-wire rope transmission eliminates blade jamming under overload, delivering higher cutting efficiency, superior flatness, and longer blade life while reducing labor and energy costs. Ideal for edge cutting and chamfering of marble, granite, arc kerbstones, and tombstones.
Key Equipment Features
1. Micro-Computer + Full-Electric Control
The one-touch program stores edge length, chamfer angle and feed rate
No hydraulics → cleaner workshop
Remote diagnostic port for on-line support
2. Gantry-Fixed / Trolley-Moving Design
15 m effective travel (extendable) → single-pass trimming of long kerbs or tombstone borders
The gantry frame absorbs vibration
Open front & rear → forklift loading, automatic in-line connection to polishing line
3. Steel-Wire Rope Transmission
The overload slip protects blades from jamming when hitting hard veins
4. Double-Blade Configuration
Upper blade → edge trimming
Lower blade → simultaneous chamfer (45° or 30° adjustable)
Both blades servo-raise/lower independently → instant switch between full-edge or chamfer-only passes
5. High Efficiency & Flatness
Feed speed: 0–6 m/min (inverter variable)
Cutting flatness: ≤ 0.2 mm / m (wire-rope float compensation)
Daily output: 300–450 lm of 150 mm granite kerb (8 h shift)
