Horizontal Belt Grinder machine for Curved Timing Belts
The Horizontal Belt Grinder for Curved Timing Belts is a compact, easy-to-use finishing machine built to grind, trim, and smooth curved timing belts and related motor or pump components. Its horizontal belt and adjustable contact wheel follow belt contours evenly, delivering consistent edge profiling and removing burrs, flash, or uneven rubber without damaging teeth or cord. Variable speed, precise tracking, and rigid clamping make it suitable for both small-batch repair and inline production, improving belt life and ensuring better fit and quieter operation.
Usage scenarios (three sentences):
- In production lines, it quickly deburrs and profiles curved timing belts after molding or cutting to ensure accurate tooth engagement and reduce vibration in motors and pumps.
- In maintenance and repair shops, technicians use it to recondition worn or slightly damaged belts and to trim excess material for a precise fit on pulleys and sprockets.
- In small factories and prototyping labs, it finishes custom or specialty rubber, polyurethane, or reinforced belts and prepares surfaces for bonding or assembly.
Secure Compact Precision Finishing
The YONGHANG horizontal CNC belt grinder delivers automated, high-precision grinding and polishing for curved timing belts and small internal/external surfaces, reducing manual rework and producing a consistent, smooth finish. PLC- and frequency-controlled speeds, dual-axis replaceable corundum wheels, customizable molding wheels, pneumatic belt tensioning, and protective covers with dust outlets ensure repeatable, durable, and safe operation. Compact horizontal layout, standard secure packing, fast lead times with low MOQ, and ISO9001-backed manufacturing provide reliable quality and quick delivery for production or sample testing.
Precision Curved Belt Grinding
This YONGHANG horizontal CNC belt grinder combines a horizontal layout with abrasive belts and customizable moulding wheels to deliver precise, high-efficiency grinding and polishing of small internal and external curved surfaces on PU rubber timing and drive belts for motor and pump applications. PLC and touch-screen control with frequency-converter motor speed regulation enable programmable automatic or manual operation—allowing adjustment of belt thickness, grinding speed, section division and depth—while a dual-axis, replaceable corundum grinding wheel and pneumatic belt tensioning ensure adaptable, repeatable machining. Equipped with a protective cover, dust outlet, quick wheel replacement and robust construction for continuous production, it offers consistent precision, low downtime and easy maintenance for high-volume synchronous belt processing.
Precision Curved Belt Grinder
The YONGHANG horizontal CNC belt grinder uses abrasive belts and customizable molding wheels to precisely grind and polish small internal and external curved surfaces on PU rubber timing and drive belts. Motor speed and grinding parameters are managed via PLC and touch screen with a frequency converter, while automatic and manual modes—including dual-axis replaceable corundum grinding wheels and pneumatic belt tensioning—enable consistent, repeatable processing. A protective cover, dust outlet, and quick delivery options (typically 3–7 days after payment) support clean operation and fast lead times for samples and production orders.

Here are three 4-word subtitle options:
Built by specialists in industrial finishing, the horizontal belt grinder for curved timing belts and motor/pump parts combines a rigid welded frame, precision-ground worktables and CNC-calibrated belt drives to deliver consistent contouring and edge finishing on complex curved profiles. Its horizontal arrangement and conforming contact wheels provide uniform abrasive contact and minimal part distortion, while variable-speed control, automatic tracking and integrated dust collection protect surface integrity and the working environment. Key features and advantages include modular tooling and quick-change abrasive belts for fast setup, adjustable fixtures and precise tension control for repeatable tolerances, a high-torque low-vibration motor for smooth throughput, and a compact footprint for easy line integration.
Material introduction
The machine’s abrasive system uses high-performance sanding belts and replaceable corundum (aluminium oxide) grinding wheels to deliver efficient cutting and fine polishing on PU rubber timing belts and other curved surfaces. Customisable moulding wheels combine durable metal cores with precision resin or polyurethane profiles, while the dual-axis grinding assembly relies on hardened steel components and precision bearings for stable, repeatable motion. The main frame and protective cover are fabricated from thick sheet steel with a dust outlet for extraction, and industrial-grade pneumatic tensioners, frequency-converter-driven motors, PLC and touch-screen controls ensure long service life and accurate process control.
