Buying Guide: Things you must keep in mind before purchasing a bench grinder machine
Before you purchase the best bench grinder for sharpening lawn mower blades, you must consider a few factors regarding bench grinder machines. These determining factors will help you select the perfect one per your need and use.
Power of Motor
One of the most critical factors of a bench grinder machine is the motor’s power. The motor is the reason which is why the wheel of the grinder rotates. Powerful motors generate higher RPM, which results in higher precision, smoothness, and accuracy in the sharpening, polishing, and shaping of tools.
So, before you purchase a bench grinder machine, you must ensure that the motor of that lathe generates a higher RPM. You need to pick motor power according to the requirements of your job.
Material
It is one of the most important things to consider before purchasing. Good material is responsible for a bench grinder machine’s stability, durability, and longevity. Lack of good material may result in the vibration and shaking of the machine while in operation.
In this regard, the best material is cast iron-based material. The iron-cast material will provide fewer vibrations and better stability. So, you must ensure that you purchase one made of cast iron-based or something better than cast iron material.
Eye protecting shield or Spark Arresting Barrier
It is s transparent flat object made of high-quality plastic. While anyone is grinding, polishing, or sharpening any metal tool, a huge amount of spark is generated from the friction of the wheel and metal tool. If these dispersing sparks hit the eyes, it may make someone partially or wholly blind. That is why a spark-arresting shield is required to protect the eyes.
So, before you purchase the bench grinder machine, you have to ensure that the machine has a transparent eye-protecting shield or spark-arresting barrier.
Built-in Work Lamp
Nowadays, most bench grinder machine comes with a built-in work lamp. This work lamp brightens the object, providing the user with a better and more detailed vision. As a grinding machine is a rotating machine, it may lead to any unexpected hazard or injury at any time due to a lack of proper vision. So, needless to say, a built-in work lamp is necessary.
So, before you purchase, you must ensure that the bench grinder has a built-in mounted work lamp. It is a crucial factor for safety.
Wheel Guard
The wheel is the essential thing a grinder must have to ensure the maximum safety of the user. The absence of a wheel guard in the grinder machine may often lead to fatal accidents or injury. An open rotating wheel without a wheel guard is like an unpinned grenade.
So, it is your compulsory duty to ensure that the grinder machine you buy must have wheel guards.
Warranty
Warranty is also an essential critical factor in purchasing a bench grinder. A bench grinder is an electric machine, so it may often face many electrical or other failure issues. In this regard, the service of the manufacturer company’s experts is needed to repair the machine.
So, before you buy the bench grinder machine, you have to ensure that the one you are buying has a minimum of 2 years of service warranty.
