Products and Technologies

Throw-away cutter for sheet surface processing of hydraulic parts

Achieves high efficiency and lowers costs compared with conventional integrated tools

a processing example (Material S50C, dry-type, Vc:60m/min、Fz:0.06mm/t)

The sheet surface of hydraulic parts is an important section where hydraulic control is performed, and standards for processing are also very tough.

For the first time in the industry, Maruichi succeeded in changing the tool exclusively for sheet surface processing, of which a solid-type had been the mainstream, into tip replacement-type model, which helps reduce costs for customers.

Maruichi also offers gauges to inspect the shape of the sheet surface after processing.

The gauges are available in four sizes: PF1/8, 1/4, 3/8, and 1/2.

This allows users to check the chamfered diameter and depth at the same time, simply by inserting them into the workpiece.

Milling cutter with adjustable tip (insert)

Groundbreaking cutter to maximize tip performance

The milling cutter “KAGAYAKIMARU series” enables the cutting-edge position to be adjusted in two directions with high accuracy, making it possible to enhance the performance of the insert to 100%.

The TF type of milling cutter for aluminum processing uses aluminum alloy for the body and the surface is treated with hard surface treatment. It is lightweight and has excellent durability.

The adjustment of the tip position is an independent mechanism for both the Z direction and radical direction and can be easily adjusted with a hexagon wrench.

In general, it is pre-set in the tool and adjusted. However, it can also be adjusted directly on the machine if it is only adjusted in the Z direction.

High-performance, high-efficiency chamfering cutter

Phenomenal ease of use based on a unique design

MTMS 20-35-45

Clean cut and high-speed machining is achieved with triple-blade composition (MTMS30 is comprised of four blades), three-face restraint, and high rigidity body. Chamfering up to 4.5C or 7C is possible in one shot by use of MTMS6.5-type or MTMS9-, 20-, and 30-types, respectively.

It is an environmentally-friendly eco-tool, as used lathe tips can also be installed.
Maruichi is also developing a dedicated tip that can improve performance even more.
(Tip specifications: DC●●0702 model, DC●●11T3 model)

It can be used like an end mill to process unprocessed materials.

Ramp cutting is possible as shown in the figure for MTMS20-35-45°and MTMS 30-45-45°.
