What is peel grinding?
Cylindrical grinding is broadly classified into “external” and “internal” grinding of cylindrical surfaces; there are many methods of external cylindrical grinding of which plunge, traverse, and centerless are the most common.
Peel grinding is also a method of cylindrical grinding. It is the most advanced method of external cylindrical grinding driven by significant advancements in the manufacturing of grinding wheels and their technologies. The word “peel” is derived from the turning process where the material is peeled as the cylindrical blank rotates and passes through a single-point cutting tool. In peel grinding, the cutting tool is replaced by a grinding wheel running at high cutting speeds to peel grind at high material removal rates.
What makes ANCA’s MX7 CNC machine platform ideal for peel grinding?
The MX7 CNC tool grinder is a versatile machine designed to meet the demands of high output and high precision cutting tool manufacturing of tools with diameter sizes from 0.1mm to 32mm. This is possible as the machine comes with a high powered 38kW grinding spindle, tubular motor on the X and Y linear axes, and a polymer concrete base for superior machine stability. In addition, the MX7 comes with a 3,000 RPM head stock. The P-axis Arobotec support system offers faster setup time for different diameters.
What are the advantages of peel grinding?
The main advantage is the large volume of material that can be ground with high material removal rates, thus significantly reducing the grinding cycle time. In most instances, the blank is ground to the required accuracy and tolerance in a single pass. This not only reduces the cycle time but also reduces the thermal or structural damages to the finished part as the grinding wheel and the part are interacting only once.
In what types of machine shops might the MX7 platform find itself?
The MX7 machine is versatile and can be found in different cutting tool manufacturing facilities, including a tool room, small-to-medium-batch and volume-production facilities, R&D centers, and resharpening shops.
How do you see the MX7 improving the efficiency of production?
As the machine is versatile, it is used in various tool grinding applications and shops. Productivity is key in these manufacturing shops, so combining peel grinding to prepare blanks and to grind tool features eliminates one separate process. Additionally, shorter setup times while changing the diameter and the ability to combine blanket grinding process make the process efficient.
What do you expect to be the market response to the MX Peel grind?
The market response is expected to be quite positive. The advanced grinding technology offers several key benefits that are likely to appeal to manufacturers:
Increased productivity: The MX7 platform significantly reduces cycle times by allowing for the grinding of various tool shapes in a single setup.
Enhanced precision: With features like the P-axis Arobotech support and a 3,000 RPM headstock, the MX7 ensures high accuracy and a superior surface finish.
Versatility: The ability to handle a wide range of tool diameters and shapes, including complex geometries such as taper ballnose and lollipop cutters, makes it a versatile solution for different manufacturing needs.
Efficiency: The platform’s capability to perform blanket grinding and bar stock loading streamlines the production process, making it ideal for batch production.
Given these advantages, the MX7 peel grinding solution is likely to be well received in industries such as automotive, aerospace, and medical device manufacturing, where precision and efficiency are critical.
