One of the major problems of grinding flat and parallel parts is achieving flatness tolerances. What could be more annoying during grinding than reworking your parts and facing rejections due to inaccurate dimensions? Rework or scrapping of parts does not only add to production costs; it reduces the efficiency and mechanical strength of the workpiece.
GCH Machinery has seen these problems happen for years and devised a solution—a new double disc grinder. This double-disc grinder can achieve high dimensional accuracy, with tight tolerances, parallelism and flatness to ±0.0002. This is possible because the GCH double disc grinder holds workpieces between two grinding wheels that rotate in opposite directions. As a result, both sides of the workpiece are simultaneously ground to the same thickness and parallelism.
What Is a Double Disc Grinder and How Does It Work?
Double disc grinding is an abrasive machining process that simultaneously grinds two sides of a workpiece. Here is how it works: a double disc grinder has its grinding discs side-mounted on a pair of opposing spindles, hence, it uses the two opposing abrasive wheels to grind two sides of a blank at the same time. When this is done, the result is a workpiece with better accuracy and higher parallelism.
One unique advantage of a double disc grinder is its speed and automation features. With a GCH double disc grinding machine, the parts feed themselves into the grinder, and you can also program wheel RPMs, feed rates and the amount of material to be removed, reducing time and cost.
Aside from GCH’s double disc grinder being able to reduce production time in half because it grinds simultaneously, the simultaneous grinding process also reduces residual stress, which is crucial to allow the workpiece to remain stable and maintain its intended shape during final machining.
GCH’s double disc grinding machine is suitable for an array of materials such as:
- Bearings
- Brake pads and rotors
- Clutch plates
- Conrods
- Engine valves
- Fuel injectors
- Pinions
- Piston rings
- Precision rings
- Races
- Rollers
- Universal joints
- Valve seats
What Are the Features and Benefits of GCH Machinery’s New Double Disc Grinder?
Here are the features and benefits of GCH Machinery’s new double disc grinder.
Part Tolerance To ±0.0002
This means that the double disc grinder can achieve highly tight dimensional tolerances. Quality standards increase every time, so you want your parts to be accurate, meet these standards and avoid any dimensional discrepancies. In fact, this is a must for industries dealing with components with precise dimensions.
Configuration For Rapid And Easy Setup
GCH’s new double disc grinder can be configured to accommodate different part sizes, shapes and materials. It can adapt to varying types of feed systems, such as rotary, through feed and reciprocating, which is perfect for heavy stock removal or extremely close tolerance requirements. It can also be used for plunge grinding and configured for an automatic, semi-automatic or manual load. These configuration options and flexibility are essential in industries with different production needs, where quick changeovers and consistent quality are important.
Servo-Controlled Dresser Arm
GCH’s double disc grinder has a servo-controlled dresser arm which can adjust the wheel speed and feed rate according to the part specifications and material properties. The servo controlled arm also ensures faster and more accurate dressing.
Full Enclosure
Full enclosure is a vital grinder accessory that prevents the coolant and debris from flying out or spilling on the floor and causing harm to the operators or damaging the surrounding equipment. This ensures your working environment stays clean always.
Integrated, Heavy-Duty, Preloaded Rolling Guide Ways
These are another important feature of GCH’s new double disc grinder. The rolling guideways are designed to support and guide the moving components of the grinding machine. These guideways also help reduce friction and wear and extend the machine’s service life.
Choose GCH Machinery’s New Double Disc Grinder
All the features of GCH’s new double disc grinding machine make it the right choice for any industry that deals with high-volume production. A double disc grinding machine can also reduce pre-machining costs by up to 50% because it does not need to grind the same part twice. This also reduces residual stress on the part and ensures it maintains stability during final machining.
