Cogsdill Tool Products Inc. will display a variety of deburring and burnishing tools designed for production machining on Swiss-type and other Cemented Carbide Inserts machines. On rod peeling inserts display will be the company’s Micro Roller Burnishing Tool series that includes internal tools for part IDs up to 0.501” in through and bottoming styles. Also on display will be external tools for ODs between 0.054-0.254” in bottoming style. The MRBT tools feature a compact design with short tool projections for use where limited space is available. The tools mount in “gang” toolholders, and they feature a rear adjustment mechanism with 0.0001” incremental adjustment capability. These easy to apply and easy to adjust tools provide the ability to obtain ultra-low surface finishes (as low as 2-4 Ra) in seconds, the company says.

I see way too many CNC programs made up exclusively of the G-code commands needed to machine a workpiece. All CNCs allow users to include clarifying messages (commonly delineated by parenthesis) within the G code. Messages are easy to include in CNC programs, even when entering them through the CNC’s Manual Data Input (MDI) keyboard.

Here are six times operators should include messages in CNC programs:

1. Program headers

Start each program with a series of messages that describe the program. Information should include anything that helps the CNC operator know that they are running the right program, including (at the very least) part name, part number, revision specification, programmer, date created and run time. For example:

Of special note are revision and run time. There may be several versions of the program floating around due to design engineering changes, so leadership must provide the operator with a way to confirm that they are using the correct program. As for run time, after running the job for the first time, including run time in the program header will let people know how long the program takes to run even when the job is not currently running.

2. At the beginning of every toolMilling inserts

If handled properly and consistently, messages placed at the beginning of every tool will serve two purposes. First, and most importantly, operators will understand the cutting tool and/or machining operation(s) being performed. They can additionally determine information about the perishable portion of each cutting tool, like insert size or number. Second, if you always place these messages just before the first G-code command for each cutting tool, the operator will know the restart block for each tool. It will always be the command right after the last message for the tool. For example:

3. At the end of each tool

The idea here is to help people performing setup size in each cutting tool as they run the first workpiece. It can also be helpful for operators during production runs Carbide Grooving Inserts after replacing dull tools. If a CNC allows cutting tools to be rerun, as machining centers and fixed headstock turning centers do, there is likely an M01 optional stop at the end of each tool that allows the setup person or operator to stop the machine and check what the tool has done.

This is the perfect place to insert a series of messages specifying what the cutting tool should have done. Messages can be specific, keeping the setup person from having to reference the workpiece drawing or other documentation, or they can be used to perform calculations, as this example shows:

If this is done for each tool, the setup person can easily check machined surfaces while running the first workpiece. If necessary, they can also adjust the related offset(s) and rerun the tool.

4. When making program changes

We tend to have a rather cavalier attitude about changing programs. While most changes may be appropriate, some may cause future issues. It is not uncommon, for instance, to forget why a change was made in the first place. Additionally, there may be times when users are asked to make changes they do not agree with. Get people in the habit of inserting a message in the program every time a change is made. Include what the command was originally, why the change was made, who made it and when it was made. Here is an example:

5. At every program stop

As the name implies, program stop commands (M00) will cause the machine to stop. All machine functions, like spindle and coolant, will be turned off. It is at this point when an operator is expected to do something. Be sure to specify exactly what it is that the operator is supposed to do, as this example shows:

6. When doing something out of the ordinary

There are times when you need to do something in a program that you do not normally do. Whenever this happens, be sure to make it clear with messages in the program. Place the related messages right at the beginning of the program so they cannot be missed. For example:

Hanwha Machinery’s XD42 is a larger-capacity Swiss-type machine designed to enable operators to produce larger-diameter Swiss parts. The 42-mm (1.653") machine with guide bushing offers an alternative for producing some parts that are too large for a standard Swiss-type lathe, especially in the automotive industry, according to the company. According to the company, the XD42 is an efficient model for setting tools a short distance from the center of the headstock.

The TNMG Insert bearings and toggles on the main and subspindles contribute to a stable machine structure along with strong chucking force via a large hydraulic cylinder as well as the machine bed’s highly rigid single-piece casting.

The machine is said to provide cost-effective parts production for heavy milling and cutting. The horizontal gang-type design offers a stable base and easy chip removal. Cross and back tools are available with ER20M as an option and a powerful motor (cross drill: 2.2 kW, 8 Nm; back drill: 1 kW, 3 Nm). The off-center drill next to the subspindle is powered by gears Carbide Turning Inserts rather than belts.

The machine provides the option of a bar lifting unit for the automatic loading and replenishing of heavy barstock. Two anti-vibration units that are designed for the V block (hybrid static block) to guide the barstock efficiently. Other options include specialized tools, a chip conveyor and a larger coolant tank.

Tungaloy is adding a set of tools with diameters ranging from 6.0 to 9.9 mm to its DrillMeister line. According to the company, DrillMeister provides TNGG Insert simple and fast drill head indexing thanks to its self-clamping system. Tool replacement is performed by simply replacing the drill head; there is no need to remove the entire drill body from the toolholder and readjust the tool overhang, reducing tool-change time. A drill head can be mounted or removed with low torque, and the process can be done in the machine as needed. Because the clamping structure prevents deformation of the drill body, the number of heads per body is substantially increased.

The new diameter ranges will be available with the TID-type drill bodies of 1.5×D, 3×D, 5×D and 8×D, ensuring high drilling performance for small-diameter holemaking in various materials. The flange-type drill body is designed for excellent chip evacuation with a high helical flute angle and polished tungsten carbide inserts flute surface. Good chip evacuation can be achieved even deep holes of 5×D or deeper, where chip evacuation tends to be difficult, the company says.

Spring Technologies will demonstrate its NCSIMUL Solutions 10, an all-in-one digital suite. The company will focus on its most popular modules in the suite, the NCSIMUL Machine and NCSIMUL CAM. With this software, users can simulate, verify, optimize and review machine programs based on the characteristics of the machine tools. According to the company, 3D graphics help to avoid machining crashes while algorithms and embedded process-based knowledge enable cutting conditions to be optimized. The software is said to reduce the time spent on debugging programs and prevent the risk of spindle collision, tool breakage and scrap. It is also designed to improve cycle times and optimize processes.

Also on display will be the NCSIMUL CAM. rod peeling inserts This module Surface Milling Inserts enables users to change the target machine without reprogramming efforts.
