Industry: Machine Tools Material: S45C Lot: 1 piece Precision: 5/1000 Application: Machine Tool Parts Machinery Used: Lathe, Machining, Grinding Product Size: Outer Diameter Φ344, Length 125 Processing Steps: Lathe - Machining - Grinding This product has strict precision requirements with both parallelism and perpendicularity at 5/1000. Due to the difficulty of gripping the product with a chuck when grinding the end face, we designed and manufactured a jig that allows us to consistently achieve a geometric tolerance of 5/1000. The product has a bowl-like shape, which posed a challenge in how to secure it during processing. We addressed this by repurposing existing jigs and designing and manufacturing new ones. With our extensive experience in processing programs, tool selection, and jig design and manufacturing, we have the know-how to handle even challenging products like this. Please contact us if you have similar products.

Model Name: NLX4000 (Yamazaki Mazak) Stroke: Ф600×750L Number of Units: 1 Features: High-precision large lathe Despite its large diameter, it can maintain a high rotation speed, resulting in a beautifully finished surface near the center. The tool post is located directly in front of the chuck, allowing for easy attachment and detachment from the front, which enhances work efficiency. It can accommodate up to 12 tools, enabling the consolidation of multiple processes. The operability of the control panel is also good, contributing to a reduction in program creation time. Although it may not be clear in the video, for diameters over Ф400, the flatness, perpendicularity, and concentricity are each achieved with an accuracy of 2/100. When machining with machines that are difficult to achieve high precision, a grinding process is necessary; however, with this high-precision large lathe, it is easily attainable, thus shortening the grinding process.

The Vertical Mate85 is a grinding machine that can simultaneously process the inner diameter, outer diameter, and end face with a single chuck. It is designed to hold products vertically, making it less susceptible to the effects of gravity and easier to achieve roundness. The single chuck processing minimizes the risk of product drop and allows for smooth centering setup, resulting in high work efficiency. Compared to horizontal grinding machines, it can perform high-precision machining more quickly and stably. The product shown in the video is a cast product with a geometric tolerance of 1/100, which would typically be challenging to process, but by using a vertical grinding machine, we can consistently achieve high precision and reliably ship to customers on time. If you are facing challenges with stable high-precision manufacturing, please feel free to contact our sales department!

This product has made cost reduction possible by being processed using a 5-axis machining center. Originally, this product required three processes in machining, but with the 5-axis machining center, it has been shortened to two processes. Additionally, since the 5-axis machining center can rotate the tool by 90°, there is no need to create jigs for setting the workpiece. Our company is reducing process and jig costs through such innovations. We are also actively accepting inquiries regarding machining cost reductions. If you are struggling with machining costs, please feel free to consult our sales department!

The LH-55-N features a counter-type turret base, which offers strong rigidity and is suitable for heavy cutting. The stroke is φ1100×2000L. Our machine excels in producing high-precision products with thin-walled pipe shapes. To reduce processing time, we have modified the square turret to accommodate 8 tools. Normally, only 4 tools can be mounted, but by installing two tools at one location, we can shorten setup time and improve production efficiency. For longer products, we ensure solid processing using a vibration stop. If you have flanges or cylindrical shapes with a diameter of 800 or less, please feel free to contact us.

Industry: Machine Tools Material: S45C Lot: 1 piece Accuracy: 2/100 Usage: Seismic isolation device parts Machining Equipment: Composite NC lathe, horizontal machining center Product Size: Outer diameter Φ150, Length 520 The machining process involves quenching and tempering material - lathe - machining. The quenched and tempered material is procured from a partner company. During the reverse R machining on the lathe, care was taken to ensure that the tool did not collide. The tolerance for the sphere is strict at 2/100. In addition to measuring only in the radial direction, multiple diagonal measurements including the Z direction were taken in conjunction with the lathe machinist and inspection as the machining progressed. In machining, the shaft-shaped part was fixed with a V-block, and the machining was carried out. However, due to poor weight balance and instability, the flat part of the sphere was supported with a screw-type locator while parallel alignment was performed on the end face during machining.

This time, I will introduce the machining of cast iron sleeves. Our company specializes in the machining of cast iron, which is often disliked by other companies. Among these, we frequently receive requests for the production of medium-sized sleeve-shaped products. This time, we are showcasing products up to the polishing stage, but we can also carry out polishing processes. Generally, lead machining on a lathe places a heavy load on the machine, so it cannot be done without a rigid machine. Additionally, since the product in this case is long, machining will be done using a steady rest. Our company excels in lathe-shaped machining such as cast iron, steady rests, and lead machining. In machining, we focus on process shortening through jigs and deep hole machining. We can accommodate depths of approximately 30 to 35 times the diameter for φ8.5 (depending on the shape size).

The "Turret Head for NC Lathes" is a product for the machine tool industry, machined from dense bar stock. After being machined from round bars using a multi-tasking lathe (5-axis), it undergoes end face grinding and outer and inner diameter grinding, followed by high-precision finishing of the tool mounting surface with horizontal machining. Since it is a component used in visible areas of NC lathe operators, careful inspection for scratches and rust is necessary. Therefore, it is a high-precision machined product that undergoes full inspection with a three-dimensional measuring machine for dimensional control. 【Features】 ■ Material: Equivalent to FCD450 (dense bar) ■ Industry: Machine tools ■ Machining equipment: Multi-tasking lathe (5-axis), horizontal rotary grinding machine, vertical multi-grinding machine ■ Precision: Coaxiality 0.005, roundness 0.005, parallelism 0.005, perpendicularity 0.05, positional accuracy 0.005, pitch ±0.005, surface error 0.005 ■ Work size: Φ340×100 *For more details, please refer to the PDF document or feel free to contact us.

The "high-precision plate machined from cast iron round bars" is machined from solid round bars of material. It requires numerous processes from NC lathe to final polishing, and further high-precision machining is necessary for the cast iron workpiece. The groove machining on the inner diameter end face requires special machining tools and methods, so we have our own unique machining know-how. By processing with a horizontal axis rotary grinding machine to achieve flatness of 0.005 or less, we finish with high precision in terms of coaxiality, perpendicularity, and cylindricity. 【Features】 ■ Material: FCD450 ■ Industry: Machine tools ■ Machining machines: NC lathe, simultaneous five-axis machining, horizontal machining, horizontal axis rotary grinding machine, vertical grinding machine ■ Precision: Coaxiality, perpendicularity, cylindricity, parallelism, flatness, all at 0.005 ■ Work size: Φ350×70L *For more details, please refer to the PDF document or feel free to contact us.
