Grinding is used for finishing workpieces requiring high surface quality (e.g. low surface roughness) and high shape and dimensional accuracy. Since the accuracy in grinding dimensions is in the order of 0.000025 mm, it tends to be a finishing operation in most applications and removes relatively little metal, approximately 0.25 to 0.50 mm deep. However, many roughing applications where grinding eliminates very quickly high metal amounts. Therefore, grinding is a broad area.
Many companies are giving valve grinding machines for sale so if you are willing to buy then you can visit their websites or locations.
Some main features of the double station valve grinding machine are as follows.
●The high production speeds.
●Telescopic arm for tensioning of the belt.
●Single-ended and double-ended machines available in two models.
The range of portable industrial valve grinders is a patented design concept which is a proven solution for re-conditioning on-site valves. Repairing leakage valves in industrial pipelines is a laborious operation involving extended downtime, losses in production and significant undesirable costs.
When valves can be grounded inside, losses are reduced, eliminating the need to uninstall or remove faulty valves from the system. These grinders are available in overlapping sizes and combine unparalleled versatility with exceptional ease of procedure and managing.
A combination guaranteed to provide cutting edge performance for these grinders, regardless of the location of the valve. Such valve grinding machines have a special, lightweight universal clamping system that enables fast and precise mounting of seats or wedges for the grinding of the valve. It is possible to carry out operational tests or remove abrasive disks without disrupting the assembly. No realignment is needed when the grinding head is repositioned.
Here are some application fields of valve grinding machine.
●The valve seat grinding machine is like a bed with an attachment to guide and hold the workpiece and a grinding wheel spinning at the obligatory speed. The speed is determined by the diameter of the wheel and the rating of the manufacturer. The grinding head can pass through a fixed workpiece, or it can shift the workpiece while the grinding head stays in a fixed position.
●Using a vernier calibrated handwheel or using the numerical control features, fine control of the grinding head or table position is possible.
●Grinding machines remove material from the workpiece, which can produce significant amounts of heat. Grinding machines incorporate a coolant to cool the workpiece so that it does not burn and exceed its lenience. The coolant also benefits the engineer as burns can be caused by the heat generated. The final grinding stages are typically set up in precision grinding machines to extract about 200 nm per step, this produces so little heat that even without a coolant, the temperature rise is minimal.
