Setting the feed and pitch of the thread being cut on an MML 180×300 machine
Information
Metric threads are specified as thread pitch. In the example above, the longitudinal carriage of the caliper moves 1.25 mm per spindle revolution. Inch thread is indicated as the number of complete turns of thread (threads) per inch of length. One inch is 25.4 mm long.
CAREFULLY!
When the lathe is turned on at high speeds and with automatic feed turned on, the longitudinal carriage of the support moves at high speed.
For example, when turning on a lathe with a thread pitch set to 1.25 mm and a spindle speed of 2500 min-1, the speed of movement of the longitudinal carriage of the support will be 52 mm per second.
Thread cutting is always performed at minimum spindle speed.
Cutting speed selection
General consideration: High cutting speeds provide time savings, low cutting speeds provide more cost-effective chips.
Factors affecting cutting speed
Fs = cutting speed [m/min]
t = tool life [min]
The durability of the cutter is the operating time of the cutter in minutes before it becomes necessary to re-sharpen it. It is of great economic importance. When processing the same material, the higher the Fs, the less the t, for example, only a few minutes at Fs = 2000 m/min.
To ensure equal t when processing different materials, different Fs are required. All data in the table below is given for certain constant parameters of the cutting mode (material, tool, etc.). When changing at least one parameter to ensure equal t, Fc must also change.
Cooling the cutting zone
When cutting, the cutting edge of the tool becomes very hot.
Therefore, it is desirable to use cooling of the cutting zone. Cooling the cutting zone with a specially designed coolant system will improve the quality of the cut and significantly extend the life of the tool.
INFORMATION
It is recommended to use a water-soluble, environmentally friendly emulsion as a coolant, which can be handed over to the seller for disposal.
Please note that all used coolant must be collected. Follow the manufacturer's instructions for disposal.
Lathe Metal Master MML 1830V
Metal Master MML 1830V is a table-top screw-cutting lathe with a variator, designed for cutting workpieces made of structural materials (steels, cast irons, non-ferrous alloys), as well as for cutting metric and inch threads.
The main advantage of the lathe: The presence of metal gears with a high service life and increased wear resistance, and the presence of a V-belt will avoid damage to the engine when the load on the spindle is exceeded
The machine is equipped with electronic stepless control of the spindle speed. Data on the number of spindle revolutions is displayed on a digital display on the machine body.
The key on the cross-feed dial mount ensures that the flywheel does not rotate inadvertently and minimizes the risk of changing the size of the part during processing.
The width of the cast iron bed is 100 mm, a record in its class, which significantly increases the rigidity of the machine and affects the processing accuracy.
The machine guides have undergone a scraping procedure, which significantly increases the accuracy of processing on a lathe.
The presence of 6 grease fittings on the lathe support allows you to quickly service and lubricate the support, avoid wear on the guides and enjoy comfortable work and smooth movement of the handle.
Availability of a scale for determining the angle of rotation of the tool holder.
The ability to rotate a thin longitudinal slide allows you to sharpen a cone of a given parameter.
A 100mm quick-release three-jaw chuck is supplied as standard.
The telescopic lead screw chip guard effectively protects the lead screw from wear.
The division price of the cross feed dial is 0.05 mm.
The division price of the fine longitudinal feed dial is 0.02 mm
The division price of the longitudinal feed dial is 0.25 mm
The machine guides have undergone high-frequency hardening (48-52 HRC) and grinding, which helps to increase the level of reliability and accuracy of part processing.
To loosen the tailstock to set the drilling depth and secure long workpieces at centers, the machine is equipped with a quick-release lever.
Tailstock quill reach 60 mm, scale up to 50 mm.
The standard equipment of the machine includes:
- 3-jaw chuck 100 mm.
- 4-position tool holder.
- The center is stubborn.
- Protective guard for the cartridge.
- Chip tray.
- Set of replacement guitar gears.
- Tool box with tools

Equipment prices
Depending on the company where you buy the machine, the price may vary. But on average, the cost of such equipment in Russia is around 50-60 thousand rubles.
If the equipment costs much less than these figures, then you should think about whether it is a fake or defective. If you buy a used machine secondhand, you can buy it 2 times less than the cost of a new one.
It is important that the small metal lathe Metal Master MML 1830 V is not only easy to use, but also inexpensive. At the same time, the quality of the equipment allows it to serve for a long time without repair.
Any home craftsman will be happy with such a machine. Small dimensions and convenient technical characteristics allow you to perform all standard metal turning operations in a home workshop or small workshop.

The machine is gorgeous, I have the same one. I work on it a lot, I’m very pleased. Precision and quality suitable for desktop home use. What I didn't like about it: the engine. Ideally, install the motor and replace the control board, it will pull perfectly at the bottom, and this is at least a plus for cutting threads. The standard engine works great and is comfortable to work with at speeds from 600-800
