CY Series Eco-friendly Dry Finishing Machine: A Waterless Polishing Solution for Precision Hardware
As environmental regulations tighten and the costs of treating wastewater and sludge from traditional wet polishing remain high, Chengyuan Automation’s CY-4010 dry finishing machine offers an ideal solution. Featuring an intelligent PLC variable-frequency control system, it operates entirely without water, balancing high productivity and superior polishing quality with environmental compliance. It is suitable for processing precision parts in sectors such as bathroom fixtures, 3C electronics, medical devices, and hardware locks.

I. Intelligent Equipment Configuration
The CY-4010 is equipped with a 7-inch touchscreen and a PLC controller. Independent variable-frequency speed control for the main spindle and the processing barrel allows it to meet the grinding requirements of various metal workpieces. The machine comes standard with a main motor and an auxiliary drive motor; it supports standard 380V voltage but can be customized for specific overseas voltage requirements. Its enclosed, sound-insulated housing keeps operating noise below 75 decibels, making it suitable for continuous workshop production. The equipment utilizes a combined orbital and rotational grinding structure with independently adjustable speeds for the barrel and spindle, ensuring all-around friction between media and workpiece—eliminating "dead zones" in complex areas like blind holes and narrow crevices.

II. Versatile Material Compatibility & One-Stop Polishing
The machine is compatible with small parts made of zinc alloy, stainless steel, aluminum, copper, and titanium alloy, handling multiple processes in a single unit:

Deburring and chamfering of die-cast and stamped parts without damaging fine threads;
Removal of machining marks and drawing scratches to achieve uniform surface roughness;
Fine polishing and brightening to achieve a mirror-like finish, with simultaneous surface passivation for rust prevention. Ideal for small-to-medium batch hardware components such as faucet fittings, electronic structural parts, medical micro-components, jewelry, and luggage zippers.
III. Core Advantages: Eco-friendly & Cost-saving Dry Processing
Zero wastewater discharge: No fresh water or liquid grinding agents are used, eliminating the need for wastewater treatment equipment and associated maintenance costs;
Low-dust sealed design: The machine features a built-in dust collection port; connecting a dust collector ensures emissions meet standards, while the dry media itself is non-polluting;
Lower media consumption: Dry grinding media offers a longer service life, effectively reducing consumable costs during long-term mass production. IV. Simple, Safe Operation and Labor Savings
The equipment features multiple safety sensors for the hopper door and overload protection, automatically stopping and sounding an alarm in the event of an anomaly. Workpieces do not require fixtures; they can be loaded directly into the hopper. The touchscreen interface stores multiple processing programs, allowing operators to work independently after brief training. A single operator can manage multiple machines simultaneously, significantly reducing labor requirements at the polishing station.

V. Industry Value
Amidst strict environmental regulations and rising labor costs, the Chengyuan CY series dry polishing machine offers three key advantages: environmental compliance, improved product yield rates, and reduced overall production costs. As the original equipment manufacturer, Chengyuan offers customized models based on workpiece specifications and daily output requirements. We provide comprehensive services—including free sample testing, on-site commissioning, and a full-machine warranty—making our equipment ideal for upgrading polishing lines in both domestic and export-oriented hardware processing plants.
