Plate Bevel Machines
Q: What are the power options for the beveling machines?
A: Common power configurations within a U.S. plant are 230/240 VAC 3-Phase 60 Hz,460/480 VAC 3-Phase 60 Hz,120 VAC 1-Phase 60 Hz. These are the standard options offered for each plate beveling machine. The standard Input voltage is 380 to 480 VAC 3 Phase 50/60 Hz. The optional input voltage is 200 to 240 VAC 3 Phase 50/60 Hz (no additional cost). For an additional fee, the machine may be configured for an input power of 500 to 600 VAC 3 Phase 50/60 Hz, or 120 VAC single phase 50/60 Hz. A cord is provided with each machine, but the customer must install a plug on the end of the cord.
Automatic Feed Plate Bevel Machines
Q: Can I upgrade a ART.9xx machine that I already purchased with one of the plate thickness options?
A: It is recommended that the customer purchase the machine with the exact thickness options they need initially. Upgrading a machine after it had been sold involves the installation of many components by a skilled technician.
Q: When should two or four wheels be used for large radius pipe beveling?
A: The two wheel ART.9xx machines are the best choice for pipe radius cutting, down to a minimum radius of 1.5 meters. The four wheel ART.9xx machines may be used to for pipe radius cutting when the radius is greater than 6 meters. Steel rollers on the table with larger diameter (rollers) provide better performance when beveling a pipe radius (special order, with original machine order or after).
Bench Plate Bevel Machines
Q: Is a cutting tool and insert included with the bench plate bevel machines?
A: All bench plate bevel machines include a cutting tool with inserts.
Portable Plate Bevel Machines
Cutting Tools & Holders
Q: What is the "Z#" reference for cutting tools?
A: The "Z#" reference is the number of cutting tool inserts that are installed into the cutting tool. For example, a "Z5" cutting tool accepts five cutting tool inserts.
Q: What is the "T" reference for cutting tools?
A: The "T" reference for cutting tools is for the Tungaloy brand of inserts. You must use Tungaloy cutting tool inserts with Tungaloy brand ("T" P/N reference) cutting tools. You can purchase these as spare parts.
Q: What is the difference between the F00011 and the F00011-T?
A: The F00011 cutter insert holder is a Stellram/Kennametal cutter and uses standardized DIN inserts. This is the cutter normally provided with the ART900 and the ART900 Reverse. The optional F00011-T cutter insert holder is a Tungaloy cutter and may require the use of only Tungaloy branded inserts. The F00011-T has shown better performance when cutting small thickness plates with less vibration. The F00011-T is available with 5 inserts (F00011-T, Z5) or 6 inserts (F00011-T, Z6.)”
Q: What are the ISO references for the cutting tool inserts?
A: See the list below for the cutter International Organization for Standardization references:
| Machine(s) | Cutter Insert | Insert Type | Cutter(s) |
|---|---|---|---|
| ART.760 | 677, 677/R | ISO SPMN 120308 | 761 (Z9) |

Q. What is the difference between a chamfer and a bevel?
A. Within the context of plate bevel machines, they are used interchangeably and are not in general intended to be differentiated. Technically a bevel is a slanted surface machined into the edge of a plate, extending completely from the top surface to the bottom surface. A chamfer is a slanted surface as well, but it does not extend fully from one surface (top) to the other parallel surface (bottom). A sloped edge at a 45 degree angle is commonly referred to as a chamfer.

Q: What is the advantage of a variable speed cutter over a constant speed?
A: The ability to vary the speed of the cutter enables you to optimize the cutting performance, resulting in improved cutting tool life, especially for higher strength / hardness materials. The higher the rotational speed of the cutting tool, the less vibration experienced by the operator, and the better the quality of the cutting finish. The smaller the diameter of the cutter, the higher the rotational speed needed to achieve the same cutting results.
Q: What is the best speed and feed rate for beveling 304 and 316 stainless steel?
A: Machine a bevel in 304 or 316 stainless steel at 600 rpm and a linear feed rate of 0.6 to 0.7 meters/min for the best cutting tool life.
Q: What is the best speed and feed for beveling Inconel and Monel materials?
A: Machine a bevel in Inconel or Monel materials with a speed of 450 to 500 rpm and a linear feed rate of 0.5 meters/min. Reducing the size of the bevel step will also improve cutting tool life.
Q: What is the material known as Monel?
A: Monel is a trade name for a group of nickel-copper alloys made by Special Metals Corporation. Monel alloys exhibit high tensile strength and resistance to corrosion. Some of the grades by trade name are "Monel 400", "Monel 401", "Monel 404", Monel K-500", and "Monel R-405".
Q: What is the material known as Inconel?
A: Inconel is a trade name for more then 20 metal alloys made by Special Metals Corporation. The alloys exhibit high resistance to corrosion, oxidation, carburization, pitting, crevice corrosion, and high temperature strength. Inconel 600 is a type of nickel-chromium alloy that withstands high temperatures and is resistant to corrosion by chloride ions and pure water. Inconel 718 contains nickel, chromium and other metals such as molybdenum, iron, niobium, aluminum and titanium. Inconel 718 is used for welding joints that can withstand temperatures up to about 1300 Fahrenheit.
Q: What is Hardox?
A: Hardox is a wear-resistant quenched and tempered sheet steel manufactured by SSAB.
Q: What is Super Duplex?
A: Super Duplex is a stainless steel that has high strength and enhanced pitting and crevice corrosion resistance. It is particularly effective in high chloride environments.
Q: What is Cladding?
A: Clad metal is a composite of two or more dissimilar metals, metallurgically bonded together.
