Zhuowang Spring Grinding Machine Series Overview
Shandong Zhuowang Machinery manufactures complete spring end grinding machines, including traditional mechanical grinders and intelligent CNC automatic grinding equipment. Our machines are specially designed for double-end surface grinding of compression springs, processing spring wire diameter from 0.3mm to 10mm, spring height from 3mm to 260mm.
Different from other suppliers, all our matching spare parts (cutters, cams, quills, mandrels, feed rollers) are made of integral high-strength solid tungsten carbide, which provides far longer service life than partial inlaid tungsten carbide accessories on the market. Matching grinding wheels are standard consumables, we recommend purchasing multiple pairs for continuous mass production. All models adopt 380V industrial power, stable operation for long-hour factory production.

H2 Matching Accessories & Consumables for Spring Grinder
1. Grinding Wheel (Main Consumable)
Grinding wheels are quick-wear parts, 2 pieces per set at factory price. We suggest customers prepare multiple pairs to avoid production shutdown. Compatible for all ZW & ZWSK models with matched wheel sizes.
2. Full Solid Tungsten Carbide Spare Parts (Our Core Advantage)
All wearing mechanical components for spring grinding machine are integrally made of high-strength tungsten carbide:
- Cutter: Full WC integral cutting knife for spring trimming
- Cam: Anti-wear forming cam discs
- Quill: Guide forming pins
- Mandrel: Spring forming core shafts
- Feed Roller: Wear-resistant wire feeding rollers Competitors only use partial inlaid tungsten carbide on the cutting edge, while our all-solid WC accessories extend service life by over 60%.
