German lorch tools lorch models lorch prices

lorch tools integrate hydraulic systems with conventional tools into a unified assembly. They convert powerful hydraulic power into mechanical motions such as reciprocating linear motion, rotary motion, and cycloidal motion. A complete hydraulic tool system consists of five components: power elements, actuating elements, control elements, auxiliary elements, and hydraulic oil. Hydraulic tools include: hydraulic wrenches, special electric pumps for hydraulic wrenches, hydraulic jacks, hydraulic bolt tensioners, hydraulic flange spreaders, hydraulic nut splitters, hydraulic pullers, etc. Hydraulic tools offer the advantages of high efficiency and convenience.

lorch tool classification

Non-sparking tools are internationally known as "safety tools" and "non-sparking tools," and domestically in China as "explosion-proof tools." Explosion-proof tools produced, sold, and distributed in China can be divided into two main categories by material: 1. Aluminum-copper alloy (commonly known as aluminum bronze) explosion-proof tools, specifically made from high-purity electrolytic copper as the base with added aluminum, nickel, manganese, iron, and other metals to form a copper-based alloy. 2. Beryllium-copper alloy (commonly known as beryllium bronze) explosion-proof tools, specifically made from high-purity electrolytic copper as the base with added beryllium, nickel, and other metals to form a copper-based alloy. Both materials exhibit excellent thermal and electrical conductivity. After heat treatment, the hardness and wear resistance of aluminum bronze are nearly identical to those of beryllium bronze, both reaching above HRC30o. Beryllium bronze is non-magnetic and can be used in strong magnetic field environments. Explosion-proof tools can also be divided into two main categories by manufacturing process: 1. Casting process: This is a traditional manufacturing technology that was internationally common for producing explosion-proof tools in the 80s and has been continuously used by most domestic explosion-proof tool manufacturers to this day. Advantages of the casting process: simple process and low manufacturing cost. Disadvantages: lower product density, hardness, tensile strength, and torque; more pores and sand holes, resulting in shorter product service life. 2. Forging process: The latest international manufacturing technology, using large presses or punch presses with high-heat-resistant forming molds to forge products in a single step. Advantages of the forging process: significantly increases product density, hardness, tensile strength, and torque; basically eliminates pores and sand holes, extending the mechanical performance and service life of products by approximately 1 times compared to traditional casting processes. Disadvantages: higher investment in equipment and molds, resulting in higher costs.

lorch tool usage

1) When placing the diamond dressing tool tip into the holder, take care not to impact the grinding wheel surface. 2) Do not align the single-point diamond dressing tool tip vertically with the center of the grinding wheel; it generally needs to be tilted 10-15°. 3) Do not "quench" (i.e., suddenly cool) heated dressing tools. During dry dressing, maintain sufficient interval time between dressings to allow the heated dressing tool to cool. 4) Do not assume the grinding wheel surface is ideally flat. At the start of dressing, locate the high spots on the grinding wheel and perform dressing. 5) If possible, the amount removed from the grinding wheel per dressing should not exceed 0.001 inches on the radius. Excessive removal can cause premature wear and frequent fracture of the diamond dressing tool tip. 6) However, do not remove too little material each time. Grinding wheels used on old or less rigid machine tools may not require dressing. 7) Note that the dressing tool should not remain in one position for too long. This will polish the grinding wheel surface, generate high temperatures, and damage the diamond dressing tool. Rotate the dressing tool at least once daily. 8) Do not continue to use worn or damaged dressing tools. Adjust or replace them promptly. 9) Do not select excessive removal amounts and fast lateral feed rates during rough dressing, and then select small removal amounts and slow lateral feed rates during fine dressing. This will quickly damage the diamond dressing tool. If possible, it is recommended to use the same lateral feed rate for both rough and fine dressing.
