"My first machine purchase the SR-2410 rim straightener, was back in 2005 followed by the MR-2540 CNC Lathe in 2006. Lehigh Machines dependability and quality can’t be beat. The short time these machines use to complete their tasks, has made us far more profitable than anything I have ever seen on the market since. Steven has always been available to answer questions and knows his product inside and out. I don’t see how a shop can function without these two machines.​"

"Still on the job after 18 years. This Lehigh MR-2540 CNC lathe was the first purchased from Lehigh Machinery . It has given us great service and still produces a top quality machine finish. We recently had to replace the mother board in the pc. We contacted Steven at Lehigh who has always been available to help with any problems or answer any questions. In a short time we had this machine back on the job. Because of the trouble free service from our first Lehigh MR-2540, we have also purchased a MR-2940 model to handle larger diameter wheels. It also produces a top quality machine finish.​"

What is the Work Process for Diamond Cut Wheel Machine?
There are a few simple steps for using Diamond Cut Wheel machine. After one alloy wheel is installed on the CNC lathe, the operator will determine which part of the rim surface is going to be machined. From that position, a digitizing probe will be used to record the profile. Then, this profile is going to be used as the path for diamond cutter to machine off a very thin layer (0.005”) of the wheel surface in order to generate the brand new refinished wheel surface.
Even though this seems to be a very simple work process for most diamond cut wheel refinishing CNC lathes available on the market now. However, each diamond cut wheel refinishing CNC lathe has its own hardware construction as well as its own matched software. The overall quality and integrity from both hardware and software must work perfectly together to make a top quality diamond cut wheel machine standing out among all the equipment out there. While you only can buy one kind of alloy wheel diamond cut CNC lathe available, you need do your home work well.
It is the overall performance and durability of that alloy wheel diamond cut machine will give the owners of the wheel shops the best value for their investment, not the initial price at all. To choose a low cost Diamond Cut Wheel machine for production purpose could result in spending lots of more money and valuable time to fix various problems and plus unexpected business interruptions and many unhappy customers. This kind of situation could be a major miscalculation for some start-up shops.
