External diameter finishing with 'external diameter film polishing'

For ultra-finish processing of various shaft outer diameters.

Our company has developed various film polishing machines with the concepts of "high precision" and "environment" and has provided them both domestically in Japan and globally. Based on our technology, experience, and many years of achievements, we are a manufacturer that designs and manufactures according to customer requirements. Our external diameter polishing machines are mainly used in the final finishing and super finishing processes of various shafts for automotive parts, contributing to improved roughness and stable process capability values. 【Applications】 ◆ Balancer shafts ◆ Input/output shafts ◆ Compressor shafts ◆ Turbocharger shafts ◆ Medical devices, etc. The polishing capability of film polishing is said to be able to achieve a roughness that is approximately half of the previous roughness per process. For example, it is possible to reduce the roughness of a shaft with a previous roughness of Rz=1.6μm to below Rz=0.8μm in 15 seconds (see diagram). Additionally, since film polishing is a contour-following process, it can improve roughness without altering the original shape.

Contec has added a BTO menu for the Windows 11-based embedded OS - Windows 11 IoT Enterprise LTSC 2024 to its industrial computer "MR4310 series" and has started accepting orders.

Contec has developed the Ethernet wireless converters "RP-WAH-SR12" and "RP-WAH-SR22," which utilize 920MHz sub-gigahertz wireless (IEEE 802.11ah) to enable Ethernet communication wirelessly even at distances of up to 1 km. Sales began on August 21, 2025. The new products are compact IEEE 802.11ah compliant wireless LAN converters that can be installed in various locations. The new Wi-Fi standard "IEEE 802.11ah," which utilizes sub-gigahertz wireless communication, became available in Japan in September 2022. It operates in the 920MHz band without the need for a license and can be used outdoors. Compared to conventional 920MHz wireless communication, it enables high-speed communication and the establishment of long-distance networks, making it expected to be utilized in large factories, plants, and farms. The new Ethernet wireless converters are designed to be lightweight and compact, allowing for installation in various locations such as walls and DIN rails with the included mounting brackets. Additionally, they support external antennas, enabling the construction of flexible wireless LAN systems.

Contec has developed a super compact business computer equipped with the Intel(R) Core(TM) Ultra processor (Series 1), and has started accepting orders for the business computer "LPC-500 Series" (hereinafter referred to as the new product) from August 28, 2025. The new product is a super compact business computer featuring the Intel(R) Core(TM) Ultra 5 processor 125U (Series 1, Meteor Lake-U). It is equipped with "Intel(R) AI Boost," which integrates an NPU into the CPU, allowing for the execution of AI functions such as image recognition and voice processing at high speed and low power consumption while reducing the load on the CPU and GPU. With ultra-compact dimensions of 150(W) × 150(D) × 33(H) mm, it comes with a vertical stand and VESA mounting brackets, enabling installation in tight spaces on desks, behind displays, or inside equipment without restriction. It adopts a BTO (Build to Order) method that allows customers to freely choose memory capacity, storage, OS, and more, enabling the order of a PC with specifications optimal for their needs and budget starting from just one unit.
